Abstract
Injury to coronary arteries during mitral surgery is a rare but life-threatening procedural complication, an anomalous origin and course of the left circumflex artery (LCx) increase this risk. Recognizing the anomaly by the characteristic angiographic pattern and identifying its relationship with the surrounding anatomical structure using imaging techniques, mainly transesophageal echocardiography (TOE) or coronary computed tomography angiography (CCTA), is of crucial importance in setting up the best surgical strategy. We report a case of anomalous origin of a circumflex artery (LCx) from the proximal portion of the right coronary artery (RCA) with a pathway running retroaortically through the mitro-aortic space. An integrated diagnostic approach using a multidisciplinary team with a cardiologist and an imaging radiologist allowed us to decide the surgical strategy. We successfully performed a mitral valvular repair using a minimally invasive minithoracotomic approach and implanting a complete semirigid ring.

Abstract
BACKGROUND The superior transseptal approach (STA) for mitral valve surgery is associated with a higher risk of developing macroreentrant incisional atrial flutter (AFL) than the left atrial approach. This study aimed to describe the linear lesions for the complex AFL circuit after the STA and to propose an option for the linear ablation target site. METHODS Of the 26 patients who underwent radiofrequency catheter ablation for AFL after mitral valve surgery, data from seven patients with STA incisions were retrospectively analyzed. RESULTS All patients who had undergone the STA had incisional AFL rotated in a long loop within the right atrium (RA) and cavo-tricuspid isthmus (CTI)-dependent AFL. The linear lesions were created in the CTI, the superior RA vestibule, and between the RA-free wall incision or the septal incision and the inferior vena cava. Procedural success was achieved with dual linear lesions in the CTI and superior RA vestibule. Two of seven patients had AFL recurrence during a mean observation period of 22.5 ± 16.7 months. The circuits of recurrent AFL were CTI-dependent AFL and perimitral AFL, respectively. No AFL recurrence was noted with reconduction of the superior RA vestibular lesion. CONCLUSION Dual linear lesions in the CTI and superior RA vestibule are an effective treatment option for RA macroreentrant AFL after the STA.

Abstract
BACKGROUND Mitral valve (MV) disease is the most common form of valvular heart disease. Findings that indicate women have a higher risk for unfavorable outcomes than men remain controversial. This study aimed to determine the sex-based differences in epidemiological distributions and outcomes of surgery for MV disease.Methods and Results: Overall, 18,572 patients (45.3% women) who underwent MV surgery between 2001 and 2018 were included. Outcomes included in-hospital death and all-cause mortality during follow up. Subgroup analysis was conducted across different etiologies, including infective endocarditis (IE), degenerative, ischemic, and rheumatic mitral pathology. The overall MV repair rate was lower in women than in men (20.5% vs. 30.6%). After matching, 6,362 pairs (woman : man=1 : 1) of patients were analyzed. Women had a slightly higher risk for in-hospital death than men (10.8% vs. 9.8%; odds ratio [OR]: 1.11, 95% confidence interval [CI]: 0.99-1.24; P=0.075). Women tended to have a higher incidence of de novo dialysis (9.8% vs. 8.6%; P=0.022) and longer intensive care unit stay (8 days vs. 7.1 days; P<0.001). Women with IE had poorer in-hospital outcomes than men; however, there were no sex differences in terms of all-cause mortality. CONCLUSIONS Sex-based differences of MV intervention still persist. Although long-term outcomes were comparable between sexes, women, especially those with IE, had worse perioperative outcomes than men.

Abstract
OBJECTIVES The aim of surgical treatment of mitral valve disease is to reverse heart failure and to restore life expectancy and quality of life (QoL). In mitral valve surgery, QoL has not been studied extensively, especially regarding the surgical approach. The current study aimed to evaluate QoL after mitral valve surgery through full sternotomy and a minimally invasive approach (MIMVS). METHODS All patients undergoing mitral valve surgery between 2013-2018 through sternotomy or a MIMVS approach (right anterolateral mini-thoracotomy, sternal-sparing), with or without concomitant tricuspid valve surgery, surgical ablation, or atrial septal defect closure were eligible for inclusion in this multicentre nationwide registry in the Netherlands. Quality of life was measured using the 12- and 36-item short form surveys, before surgery and postoperatively at 1 year. Independent predictors for loss of QoL were evaluated. RESULTS 485 patients were included (full sternotomy: n = 276, and MIMVS: n = 209). Overall, patients experienced a significant increase in physical component score (56 [42-75] vs 74 [57-88], p < 0.001) and mental component score at 1-year (63 [52-74] vs 70 [59-86], p < 0.001). Baseline QoL scores and new onset of atrial arrhythmia were independently associated with a clinically relevant reduction in physical and mental QoL. CONCLUSIONS Mitral valve surgery is associated with significant improvement in physical and mental QoL. Baseline QoL scores and new onset of atrial arrhythmia are associated with a clinically relevant reduction in postoperative QoL.

Abstract
BACKGROUND Cox-Maze procedure is currently the gold standard treatment for atrial fibrillation (AF). However, data on the effectiveness of the Cox-Maze procedure after concomitant mitral valve surgery (MVS) are not well established. The aim of this study was to assess the safety and efficacy of Cox-Maze procedure versus no-maze procedure n in AF patients undergoing mitral valve surgery through a systematic review of the literature and meta-analysis. METHODS A systematic search on PubMed/MEDLINE, EMBASE, and Cochrane Central Register of Clinical Trials (Cochrane Library, Issue 02, 2017) databases were performed using three databases from their inception to March 2023, identifying all relevant randomized controlled trials (RCTs) comparing Cox-Maze procedure versus no procedure in AF patients undergoing mitral valve surgery. Data were extracted and analyzed according to predefined clinical endpoints. RESULTS Nine RCTs meeting the inclusion criteria were included in this systematic review with 663 patients in total (341 concomitant Cox-Maze with MVS and 322 MVS alone). Across all studies with included AF patients undergoing MV surgery, the concomitant Cox-Maze procedure was associated with significantly higher sinus rhythm rate at discharge, 6 months, and 12 months follow-up when compared with the no-Maze group. Results indicated that there was no significant difference between the Cox-Maze and no-Maze groups in terms of 1 year all-cause mortality, pacemaker implantation, stroke, and thromboembolism. CONCLUSIONS Our systematic review suggested that RCTs have demonstrated the addition of the Cox-Maze procedure for AF leads to a significantly higher rate of sinus rhythm in mitral valve surgical patients, with no increase in the rates of mortality, pacemaker implantation, stroke, and thromboembolism.

Abstract
BACKGROUND Left atrial dissection (LAtD) is a rare but potentially life-threatening complication of mitral valve surgery. Its management is not well stablished in the literature. However, early recognition through intraoperative TEE and attention to changes in the left atrial free wall during saline leak testing can lead to avoidance of severe complications. CASE PRESENTATION We report a case of LAtD detected by intraoperative transesophageal echocardiogram (TEE) following mitral valve repair for primary mitral valve regurgitation secondary to degenerative mitral valve disease with MAZE IV procedure for atrial fibrillation. LAtD was noted on TEE as an expanding double density along the wall of the left atrium with a jet originating at the posterior annulus flowing into the LAtD which was repaired. Separation from bypass following LAtD repair was complicated by severe biventricular dysfunction requiring significant inotropic support and placement of an intra-aortic balloon pump (IABP). Patient's post-operative course was further complicated by right sided heart failure requiring placement of a right sided impella which was subsequently removed on POD 4. Patient was discharged home on POD 17. Transthoracic echo at 1 month, 3 months demonstrated resolution of the LAtD. A follow up echo at 4 years showed complete resolution of the LAtD with an intact mitral repair, trace mitral regurgitation, and a mean gradient across the repair of 3 mm Hg. CONCLUSIONS Left atrial dissection is a rare but serious complication of mitral valve surgery. We provide a review of the current literature regarding LAtD, emphasizing the need to consider this complication early during mitral surgery to allow for uncomplicated repair.

Abstract
PURPOSE Mitral valve surgery in children involves correcting congenital and acquired pathologies, with a reported mortality rate of 0.9%. Low cardiac output syndrome (LCOS) is a serious complication with the incidence of 20-25%. The aim of the study was to estimate possible prognostic factors of LCOS in children undergoing mitral valve procedure. MATERIAL AND METHOD This single-center retrospective analysis enrolled children aged <18 years who underwent mitral valve surgery during 24 year period. Preoperative clinical and laboratory parameters, and operative factors were analyzed. RESULTS Thirty consecutive pediatric patients (11 (37%) males and 19 (63%) females) in median (Q1 - Q3) age of 57 (25-115) months, who underwent mitral valve replacement, were included. The 30-day mortality was 7% (2 patients) and was related to postoperative multiorgan failure. LCOS occurred in 8 (27%) children. The receiver operator curve (ROC) analysis established parameters that have predictive value for LCOS occurrence: cardiopulmonary bypass (CPB) time, with 89 min as optimal cut-off point (AUC = 0.744, p = 0.011) yielding sensitivity of 100% and specificity of 42.9%; left ventricular ejection fraction (LVEF) < 60 % (AUC = 0.824, okp = 0.001) with sensitivity of 62.5% and specificity of 93.75%; and red blood cell distribution width (RDW) above 14.5 % (AUC = 0.840, p < 0.001; sensitivity of 87.5% and specificity of 75%). CONCLUSIONS In mitral valve replacement in pediatric patients, CPBtime above 89 min, preoperative LVEF below 60% and preoperative RDW above 14.5% can be regarded as the potential predictors of LCOS.

Abstract
BACKGROUND Transcatheter mitral valve replacement (TMVR) faces anatomical challenges, currently limiting widespread adoption. OBJECTIVES To describe the natural history and prognosis of patients ineligible for various TMVR devices. METHODS During a 4-year period (2019-2023) 3 TMVR devices (SAPIEN M3, Intrepid and Alta Valve) became available at a single institution (The Christ Hospital, Cincinnati, OH) in the setting of pivotal clinical trials or early feasibility study. Consenting patients who were deemed ineligible ≥1 of these trials were prospectively studied to capture anatomical reasons for ineligibility, cross-over to alternative mitral valve therapies (surgery or high-risk mitral transcatheter edge to edge repair [M-TEER]), and clinical events. RESULTS A total of 61 patients (out of 71 consenting patients or 85.9 %) were deemed ineligible for TMVR during the study period. The mean age was 79.2 ± 8.8 years, 65.6 % were female, with elevated surgical risk (median STS 4.3, IQR: 2.7-7.3). The 2 most common anatomical reasons for ineligibility were increased risk of left ventricular outflow tract obstruction (LVOTO) (n = 24, 39.3 %) and annular size (n = 29, 47.5 %). During follow-up (median 277 [162-555] days) there were 7 deaths (11.5 %) and 12 (19.7 %) hospitalizations for heart failure. Management strategies included high-risk M-TEER in 11 patients (1 death [9.0 %], 0 HF hospitalizations [0 %]), surgery in 9 patients (0 deaths, 1 HF hospitalizations [11.1 %]), and medical management in 41 patients (6 deaths [14.6 %], 11 HF hospitalizations [26.8 %]) (p = 0.715 for mortality and p = 0.093 for HF hospitalizations). Residual MR ≥ moderate was 0 %, 50 %, and 100 % for surgery, M-TEER and medical treatment, respectively (p < 0.001). CONCLUSIONS One third of patients deemed ineligible for TMVR are candidates for high-risk M-TEER or surgery with acceptable morbidity and mortality. Our results have practical implications for patient management.

Abstract
BACKGROUND This study aimed to report the risk and learning curve analysis of a minimally invasive mitral valve surgery program performed through a right mini-thoracotomy at a single institution. METHODS From January 2013 through December 2019, 266 consecutive patients underwent minimally invasive mitral valve surgery in our department and were included in the current study. Multiple logistic regression analysis was used for the adverse event outcome. Distribution over time of perioperative complications, defined as clinical endpoints in the Valve Academic Research Consortium-2 (VARC-2) consensus document, as well as CUSUM charts for assessment of cardiopulmonary bypass and aortic cross-clamping duration over time, has been performed for learning curve assessment. RESULTS Overall incidences of postoperative stroke (1.1%), myocardial infarction (1.1%), and thirty-day mortality (1.5%) were low. The mitral valve reconstruction rate in our series was 95%. Multivariable analysis revealed that concomitant tricuspid valve surgery (OR 4.44; 95%CI 1.61-11.80; p = 0.003) was significantly associated with adverse event outcomes. Despite a trend towards adverse event outcomes in patients with preexisting active mitral valve endocarditis (OR 2.69; 95%CI 0.81-7.87; p = 0.082), mitral valve pathology did not significantly impact postoperative morbidity and mortality. Distribution over time of perioperative complications, defined as clinical endpoints in the VARC-2 consensus document, showed a trend towards an improved complication rate after the initial 65-100 procedures. CONCLUSIONS Mitral valve surgery via right-sided mini-thoracotomy can be implemented safely with low perioperative morbidity and mortality rates. Careful patient selection regarding isolated mitral valve surgery in the presence of degenerative mitral valve disease may represent a significant safety issue during the learning curve. TRIAL REGISTRATION The cantonal ethics commission of Zurich approved the study (registration ID 2020-00752, date of approval 24 April 2020).

Abstract
Introduction Mitral valve repair (MVr) has been shown to achieve better outcomes than mitral valve replacement (MVR) in degenerative aetiology. However, that cannot be applied in rheumatic mitral valve disease. Therefore, this study aims to evaluate early and late clinical outcomes and mid-term survival in RHD compared to the non-RHD group and whether mitral valve repair is a better surgical approach in RHD patients. Methods Patients who underwent mitral valve surgery with or without coronary artery bypass grafting were included in this study. All patients were divided into the RHD and non-RHD group by the type of mitral surgery performed. Early and late outcomes were evaluated, and mid-term cumulative survival was reported. Results A total of 1382 patients post MV surgeries were included. The 30-day mortality was significantly higher in the RHD group compared to the non-RHD group (8.7% vs. 4.4%, p = 0.003). There was no difference in 30-day mortality between repair and replacement in each respective group. During follow-up (12-54 months), all-cause mortality between RHD and non-RHD groups (16.7% vs. 16.2%) was not different. In the RHD group, the survival of MVr was 85.6% (95% CI 82.0%-88.5%), and MVR was 78.3% (95% CI 75.8%-80.6%), p-value log rank 0.26 However, in the non-RHD group, patients who underwent MVr had better survival than MVR, with cumulative survival of 81.7% (95% CI 72.3%-88.2%) vs. 71.1% (95% CI 56.3%-81.7%) p-value log rank 0.007. Conclusion Early mortality rate in rheumatic mitral valve surgery was higher than in non-rheumatic valve surgery. Although in rheumatic MV disease MV repair did not show a significant survival advantage over MV replacement, a trend towards more favourable survival in the repair group was observed.

Abstract
BACKGROUND Global trends in mitral valve surgery (MVSx) suggest increasing repair compared with replacement, especially in the United States and European countries. The relative use, and outcomes of, MV repair and replacement in Australia are unknown. METHODS New South Wales residents who underwent isolated MVSx between 2001 and 2017 were identified from the Admitted-Patient-Data-Collection database. Mortality outcomes were tracked to 31 Dec 2018 and adjusted based on age, sex, urgency of operation, and comorbidity status. RESULTS The study cohort comprised 5,693 patients: 2020 (35%) underwent repair (MVr), 1,656 (29%) underwent mechanical replacement (mech.MVR), and 2017 (35%) underwent bioprosthetic replacement (bio.MVR). Respective median ages [interquartile range] were 67 yo [59-75 yo], 64 yo [55-71 yo], and 75 yo [68-80 yo] (p<0.001 across groups). Between 2001 and 2017, total MVSx increased steadily with population growth. Whereas the relative use of MVr remained static (34% to 38%), that for bio.MVR (22% to 50%) and mech.MVR (45% to 13%) changed significantly. MVr had the best outcome with 1.2% in-hospital, 2.5% 1-year, and 21.6% total cumulative mortality during a median follow-up of 6.5 years. Compared to MVr, the adjusted hazard ratio (aHR) for mech.MVR and bio.MVR for long-term mortality were 1.41 (95% confidence interval [CI]=1.24-1.61) and 1.73 (95% CI=1.53-1.95), respectively. Heart failure and sepsis were the main cardiovascular and noncardiovascular causes of death in all groups. CONCLUSION In this statewide Australian cohort examined over 17 years, MVr is potentially underutilised despite having superior outcomes to MVR. Access to quality dataset which provides the indication for MVSx and quantitative clinical factors is critical to further improve MVr coverage and outcome MVSx.

Abstract
Mitral annular disjunction is a cardiac structural abnormality characterized by the distinct separation between the top of the left ventricular myocardium and the mitral annulus supporting the posterior mitral leaflet occurring during systole. It has recently gained wide attention due to the increasing recognition of the link between mitral annular disjunction and arrhythmogenic mitral valve prolapse, particularly, with the increased risks of ventricular arrhythmias resulting in sudden cardiac death. This review has summarized the recent progress in the diagnostic modalities, clinical implications of mitral annular disjunction, and its specific surgical considerations.

Abstract
BACKGROUND The management of an enlarged left atrium (LA) in mitral valve (MV) disease with atrial fibrillation (AF) is still being debated. It has been postulated that a reduction in LA size may improve patient outcomes. This meta-analysis aimed to assess rhythm and clinical outcomes of combined surgical AF treatment with or without LA volume reduction (LAVR) in patients undergoing MV surgery. METHODS A systematic review was performed and all available literature to May 2022 was included. The primary endpoint was analysis of early and late mortality and rhythm outcomes. Secondary outcomes included early and late cerebrovascular accident (CVA) and permanent pacemaker implantation. RESULTS The search strategy yielded 2,808 potentially relevant articles, and 19 papers were eventually included. The pooled estimated rate of 30-day mortality was 3.76% (95% CI 2.52-5.56). The incidence rate of late mortality and late cardiac-related mortality was 1.75%/year (95% CI 0.63-4.84) and 1.04%/year (95% CI 0.31-3.53), respectively. At subgroup analysis when comparing the surgical procedure with and without AF ablation, the ablation subgroup showed a significantly lower rate of postoperative CVA (p<0.0001) and higher restoration to sinus rhythm at discharge (p=0.0124), with only a trend of lower AF recurrence at 1 year (p=0.0608). At univariable meta-regression, reintervention was significantly associated with higher late mortality (p=0.0033). CONCLUSION In enlarged LA undergoing MV surgery, LAVR combined with AF ablation showed a trend of improved rhythm outcomes when compared with AF ablation without LAVR. Each LAVR technique has its advantages and disadvantages, which must be managed accordingly.

Abstract
OBJECTIVES The aim of this study was to examine the incidence and predictors of stroke after minimally invasive mitral valve surgery (mini-MVS) and to assess the role of preoperative CT scan on surgical management and neurological outcomes in the large cohort of Mini-Mitral International Registry. METHODS Clinical, operative and in-hospital outcomes in patients undergoing mini-MVS between 2015 and 2021 were collected. Univariable and multivariable analyses were used to identify predictors of stroke. Finally, the impact of preoperative CT scan on surgical management and neurological outcomes was assessed. RESULTS Data from 7343 patients were collected. The incidence of stroke was 1.3% (n = 95/7343). Stroke was associated with higher in-hospital mortality (11.6% vs 1.5%, P < 0.001) and longer intubation time, ICU and hospital stay (median 26 vs 7 h, 120 vs 24 h and 14 vs 8 days, respectively). On multivariable analysis, age (odds ratio 1.039, 95% confidence interval 1.019-1.060, P < 0.001) and mitral valve replacement (odds ratio 2.167, 95% confidence interval 1.401-3.354, P < 0.001) emerged as independent predictors of stroke. Preoperative CT scan was made in 31.1% of cases. These patients had a higher risk profile and EuroSCORE II (median 1.58 vs 1.1, P < 0.001). CT scan influenced the choice of cannulation site, being ascending aorta (18.5% vs 0.5%, P < 0.001) more frequent in the CT group and femoral artery more frequent in the no CT group (97.8% vs 79.7%, P < 0.001). No difference was found in the incidence of postoperative stroke (CT group 1.5, no CT group 1.4%, P = 0.7). CONCLUSIONS Mini-MVS is associated with a low incidence of stroke, but when it occurs it has an ominous impact on mortality. Preoperative CT scan affected surgical cannulation strategy but did not led to improved neurological outcomes.

Abstract
This case presents a Commando procedure with posterior atrioventricular groove reconstruction in a patient after double-valve replacement performed in another hospital with a posterior atrioventricular groove patch due to mitral annular calcification for aortomitral Streptococcus agalactiae endocarditis. The patient was transferred to our institution on postoperative day 6 under femoro-axillary venoarterial extracorporeal membrane oxygenation with cardiogenic shock and pulmonary oedema due to patch dehiscence and severe periprosthetic mitral leak. To control pulmonary oedema and decrease myocardial tension, left atrial venting was performed in the intensive care unit through a redo sternotomy. After 24 hours, repeat reconstruction surgery was performed after improvement of pulmonary infiltrates and contractility. We alternate operative images with a porcine wet-lab model to facilitate understanding of this advanced reconstruction.

Abstract
BACKGROUND There is still ongoing debate about the benefits of mini-thoracotomy (MTH) approach in mitral valve surgery in comparison with complete sternotomy (STER). This study aims to update the current evidence with mortality as primary end point. METHODS The MEDLINE and EMBASE databases were searched through June 2022. Two randomized studies and 16 propensity score matched studies published from 2011 to 2022 were included with a total of 12,997 patients operated on from 2005 (MTH: 6467, STER: 6530). Data regarding early mortality, stroke, reoperation for bleeding, new renal failure, new onset of atrial fibrillation, need of blood transfusion, prolonged ventilation, wound infection, time-related outcomes (cross clamp time, cardiopulmonary bypass time, ventilation time, length of intensive care unit stay, length of hospital stay), midterm mortality and reoperation, and costs were extracted and submitted to a meta-analysis using weighted random effects modeling. RESULTS The incidence of early mortality, stroke, reoperation for bleeding and prolonged ventilation were similar, all in the absence of heterogeneity. However, the sub-group analysis showed a significant OR in favor of MTH when robotic enhancement was used. New renal failure (OR 1.67, 95% CI 1.06-2.62, p = 0.03), new onset of atrial fibrillation (OR 1.31, 95% CI 1.15-1.51, p = 0.001) and the need of blood transfusion (OR 1.77, 95% CI 1.39-2.27, p = 0.001) were significantly lower in MTH group. Regarding time-related outcomes, there was evidence for important heterogeneity of treatment effect among the studies. Operative times were longer in MTH: differences in means were 20.7 min for cross clamp time (95% CI 14.9-26.4, p = 0.001), 36.8 min for CPB time (95% CI 29.8-43.9, p = 0.001) and 37.7 min for total operative time (95% CI 19.6-55.8, p < 0.001). There was no significant difference in ventilation duration; however, the differences in means showed significantly shorter ICU stay and hospital stay after MTH compared to STER: - 0.6 days (95% CI - 1.1/- 0.21, p = 0.001) and - 1.88 days (95% CI - 2.72/- 1.05, p = 0.001) respectively, leading to a significant lower hospital cost after MTH compared to STER with difference in means - 4528 US$ (95% CI - 8725/- 326, p = 0.03). The mid-term mortality was significantly higher after STER compared to MTH: OR = 1.50, 1.09-2.308 (95% CI), p = 0.01; the rate of mid-term reoperation was reported similar in MTH and STER: OR = 0.76, 0.50-1.15 (95% CI), p = 0.19. CONCLUSIONS The present meta-analysis confirms that the MTH approach for mitral valve disease remains associated with prolonged operative times, but it is beneficial in terms of reduced postoperative complications (renal failure, atrial fibrillation, blood transfusion, wound infection), length of stay in ICU and in hospitalization, with finally a reduction in global cost. MTH approach appears associated with a significant reduction of postoperative mortality that must be confirmed by large randomized study.

Abstract
BACKGROUND Functional mitral regurgitation (FMR) worsens the prognosis of patients with heart failure with preserved ejection fraction (HFpEF). While concomitant mitral valve surgery (MVS) is recommended for severe FMR during aortic valve replacement (AVR), the optimal treatment of moderate FMR, especially in those with HFpEF, remains unclear. This study aimed to evaluate the effect of MVS in patients with moderate FMR and HFpEF undergoing AVR. METHODS A total of 212 consecutive patients (AVR: 34.0%, AVR-MVS: 66.0%) during 2010 and 2019 were enrolled. Survival outcomes were compared. Inverse probability treatment weighting (IPTW) was used to balance the baseline characteristics. Kaplan-Meier curve and log-rank test were applied to compare the survival outcomes. The primary endpoint was the overall mortality. RESULTS The mean age was 58.9 [Formula: see text] 11.9 years, and 27.8% of them were female. During a median follow-up of 16.4 months, AVR-MVS did not reduce the risk of mid-term MACCE (hazard ratio [HR]: 1.53, 95% confidence interval [CI]: 0.57-4.17, Plog-rank = 0.396), while it showed a tendency toward higher MACCE risk in the IPTW analysis (HR: 2.62, 95% CI: 0.84-8.16, Plog-rank = 0.096). In addition, AVR-MVS increased the risk of mortality as compared to isolated AVR (0 vs. 10%, Plog-rank = 0.016), which was sustained in the IPTW analysis (0 vs. 9.9%, Plog-rank<0.001). CONCLUSION In patients with moderate FMR and HFpEF, isolated AVR might be more reasonable than AVR-MVS.

Abstract
OBJECTIVES There is still ongoing debate about the benefits of robotic assistance (R-MVS) in comparison with video assistance (V-MVS) in minimally invasive mitral valve surgery. This study aims to update the current evidence. METHODS Three propensity score-matched studies published from 2011 to 2021 were included with a total of 1193 patients operated on from 2005 (R-MVS: 536, V-MVS: 657). Data regarding early mortality, postoperative event, and time-related outcomes were extracted and submitted to a meta-analysis using weighted random-effects modeling. RESULTS The incidence of early mortality, stroke, renal failure, conversion, atrial fibrillation, and prolonged ventilation were similar, all in the absence of heterogeneity. Reoperation for bleeding (odds ratio [OR]: 0.36, 95% confidence interval [CI] 0.16-0.81, p = 0.01) and the need for blood transfusion (OR: 0.30, 95% CI, 0.20-0.56, p = 0.001) were significantly lower in V-MVS group. Regarding time-related outcomes, there was evidence for important heterogeneity of treatment effect among the studies. Operative times were longer in R-MVS: differences in means were 20.7 min for cross-clamp time (95% CI, 9.07-32.3, p = 0.001), 20.7 min for cardiopulmonary bypass time (95% CI, 2.5-38.9, p = 0.03) and 40.2 min for total operative time (95% CI, 24.5-55.8, p < 0.001). Intensive care unit stay and hospital stay were reported in one study, and longer after R-MVS compared to V-MVS; the differences in means were 0.17 days (p = 0.005) and 0.6 days (p = 0.017), respectively. Total cost of both procedures was reported in an additional dedicated propensity score-matched series including 448 patients; it was 21% higher for R-MVS than for V-MVS. CONCLUSIONS This meta-analysis showed excellent outcomes of both video and robotic techniques with low incidence of morbidity and mortality. However, there is no evidence for an added value of robotic assistance in comparison with video assistance; the drawbacks of mini access are reported higher regardless the induced over cost.

Abstract
We compare outcomes of endo-aortic balloon occlusion (EABO) vs external aortic clamping (EAC) in patients undergoing minimally invasive mitral valve surgery (MIMVS) in the Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database. Adults undergoing mitral valve surgery (July 2017-December 2018) were identified within the STS database (N = 60,607). Total 7,978 patients underwent a minimally invasive approach (including robotically assisted). About 1,163 EABO patients were 1:1 propensity-matched to EAC patients using exact matching on age, sex, and type of mitral procedure, and propensity score average matching for 16 other risk indicators. Early outcomes were compared. Categorical variables were compared using logistic regression; hospital and intensive care unit length of stay were compared using negative binomial regression. In the matched cohort, mean age was 62 years; 35.9% were female, and 86% underwent mitral valve repair. Cardiopulmonary bypass time was shorter for EABO vs EAC group (125.0 ± 53.0 vs 134.0 ± 67.0 minutes, P = 0.0009). There was one aortic dissection in the EAC group and none in the EABO group (P value > 0.31), and no statistically significant differences in cross-clamp time, major intraoperative bleeding, perioperative mortality, stroke, new onset of atrial fibrillation, postoperative acute kidney injury, success of repair. Median hospital LOS was shorter for EABO vs EAC procedures (4 vs 5 days, P < 0.0001). In this large, retrospective, STS database propensity-matched analysis ofpatients undergoing MIMVS, we observed similar safety outcomes for EABO and EAC, including no aortic dissections in the EABO group. The EABO group showed slightly shorter CPB times and hospital LOS.

Abstract
BACKGROUND The cut-and-sew maze (CSM) procedure has an excellent efficacy for the elimination of long-standing persistent atrial fibrillation (AF) concomitant with mitral valve surgery. Because of the complexity and prolongation of cardiopulmonary bypass, CSM has not been widely used. The aim of this study was to examine a modified maze procedure that preserves the "cut-and-sew" procedure in the left atrium and uses cryoablation in the right atrium along with cavotricuspid isthmus. METHODS From December 2013 to December 2018, 229 patients underwent CSM, and 43 underwent the modified maze procedure during mitral valve surgery. Propensity score matching analysis was used to perform selective 1:2 ratio matching of the 43 patients undergoing the modified maze procedure with 86 patients undergoing CSM. Early operative outcomes were analyzed for differences. The absence of AF recurrence without the use of anti-arrhythmic drugs was calculated at 2 years by a generalized linear model analysis. RESULTS One (1.1%) early death occurred in the CSM group, and no deaths occurred in the modified maze group (p=0.722). The aortic cross-clamp durations were 76.30±8.86 minutes for the modified maze and 92.38±10.88 for the CSM procedure (p<0.001). There were no late strokes or deaths during the 2-year follow-up. The modified maze group showed similar rates of absence of AF without the use of anti-arrhythmic drugs as the CSM group within the 2 years (p=0.332). CONCLUSION This modified maze simplifies the "cut-and-sew" procedure and reduces operating time while retaining the efficacy of CSM.

Abstract
Tricuspid regurgitation (TR) severity after mitral transcatheter edge-to-edge repair (TEER) has been shown to impact outcomes but unknown in patients requiring mitral valve (MV) surgery after TEER. We sought to determine the impact of preoperative TR severity and right ventricular (RV) dysfunction on MV surgery after TEER. From 7/2009 to 7/2020, 260/332 patients in the CUTTING-EDGE registry who underwent MV surgery after TEER had paired echocardiographic evaluation on TR severity, and ≥moderate (2+) vs <2+ TR at the time of index TEER were compared. Median follow-up post-MV surgery was 9.1 months, 96.5% complete at 30 days and 81.9% complete at 1 year. Mean age was 73.8 ± 10.3; with primary/mixed and secondary MR present in 65.6% and 32.0%, respectively. Proportion of ≥2+ TR increased from TEER to MV surgery (40% vs 57%, P < 0.001). Compared to <2+ TR group, ≥2+ pre-TEER TR patients were older, had higher STS risk score at TEER, higher RVSP, more RV dysfunction, more MR post-TEER, and a shorter median interval from TEER to MV surgery (1.9 vs 4.9 months, P = 0.023). Mortality was higher in the ≥2+ pre-TEER TR group at 30 days(24.2% vs 13.8%, P = 0.043) and 1 year (45.3% vs 22.3%, P = 0.003). On Kaplan-Meier analysis, cumulative mortality was 23.8% at 1 year and 31.6% at 3 years after MV surgery overall, and was associated with preoperative RV dysfunction (P = 0.023), ≥2+ TR at pre-TEER (P = 0.001) and presurgery (P = 0.004), but not concomitant tricuspid surgery. Moderate or greater pre-TEER TR was associated with worse outcomes, and pre-TEER TR worsened significantly at MV surgery. Concomitant tricuspid surgery did not increase overall mortality.

Abstract
OBJECTIVES Concerns exist about higher rates of pacemaker implantation using the extended superior transseptal approach for mitral valve surgery. This study aims to compare the extended superior transseptal and the left-atrial approach regarding the need for pacemaker implantation after mitral valve surgery. METHODS We performed a retrospective analysis of the data of patients undergoing mitral valve surgery through either a sternotomy and transseptal approach or a mini-thoracotomy and left-atrial approach in a single center in the period 01/2010-05/2021. The primary outcome was the evaluation of the postoperative pacemaker implantation rate. RESULTS Overall, 677 patients were included, 333 with transseptal and 344 with left-atrial approach, and 58 (8.6%) patients underwent pacemaker implantation postoperatively. There was no significant difference in the rate of pacemaker implantation between the two groups [overall: 34(10.2%) vs 24(7%), p = 0.133; for sinus node dysfunction: 12(3.6%) vs 9(2.6%), p = 0.459; for high-degree atrioventricular block: 22(6.6%) vs 15(4.4%), p = 0.199; transseptal vs left-atrial approach respectively]. A subgroup analysis of the relative effect of transseptal vs left atrial approach on the rate of postoperative pacemaker implantation revealed mitral replacement as a statistically significant confounder (p = 0.019). The exclusion of patients undergoing concomitant cardiac procedures did not lead to a statistically significant difference in the pacemaker implantation rate between the two approaches. CONCLUSIONS The analysis of the data of these patients shows no significant difference in the rate of permanent pacemaker implantation between the extended superior transseptal and the left-atrial approach for mitral valve surgery.

Abstract
BACKGROUND Rheumatic heart disease remains one of the leading causes of heart valve disease worldwide despite being a preventable condition. Mitral valve repair is superior to replacement in severe degenerative mitral valve disease, however its role in rheumatic valve disease remains controversial. This meta-analysis compared mitral valve repair and replacement in rheumatic heart disease. METHODS Medline, EMBASE, Cochrane and Scopus were searched from January 1980 to June 2016 for original studies reporting outcomes of both mitral valve repair and replacement in rheumatic heart disease in adults, children or both. Two (2) authors independently assessed studies for inclusion, followed by data extraction and analysis. RESULTS The search yielded 930 articles, with 98 full-texts reviewed after initial screening and 13 studies subsequently included for analysis, totalling 2,410 mitral valve repairs and 3,598 replacements. Pooled rates and odds ratio (95% confidence interval) for operative mortality of repair versus replacement was 3.2% versus 4.3%, 0.68 (0.50-0.92; p=0.01). Pooled odds ratios (95% confidence interval) were for long-term mortality 0.41 (0.30-0.56; p<0.001); reoperation 3.02 (1.72-5.31; p<0.001); and bleeding 0.26 (0.11-0.63; p=0.003). There was a trend towards lower thrombo-embolism 0.42 (0.17-1.03; p=0.06), and no significant difference in endocarditis (p=0.76), during follow-up. CONCLUSION Mitral valve repair is associated with reduction in operative and long-term mortality and bleeding, so is recommended in rheumatic mitral valve disease where feasible, but it does entail a higher rate of reoperation during follow-up.

Abstract
AIMS Transcatheter mitral valve implantation (TMVI) represents a novel treatment option for patients with mitral regurgitation (MR) unsuitable for established therapies. The CHOICE-MI registry aimed to investigate outcomes of patients undergoing screening for TMVI. METHODS AND RESULTS From May 2014 to March 2021, patients with MR considered suboptimal candidates for transcatheter edge-to-edge repair (TEER) and at high risk for mitral valve surgery underwent TMVI screening at 26 centres. Characteristics and outcomes were investigated for patients undergoing TMVI and for TMVI-ineligible patients referred to bailout-TEER, high-risk surgery or medical therapy (MT). The primary composite endpoint was all-cause mortality or heart failure hospitalization after 1 year. Among 746 patients included (78.5 years, interquartile range [IQR] 72.0-83.0, EuroSCORE II 4.7% [IQR 2.7-9.7]), 229 patients (30.7%) underwent TMVI with 10 different dedicated devices. At 1 year, residual MR ≤1+ was present in 95.2% and the primary endpoint occurred in 39.2% of patients treated with TMVI. In TMVI-ineligible patients (n = 517, 69.3%), rates of residual MR ≤1+ were 37.2%, 100.0% and 2.4% after bailout-TEER, high-risk surgery and MT, respectively. The primary endpoint at 1 year occurred in 28.8% of patients referred to bailout-TEER, in 42.9% of patients undergoing high-risk surgery and in 47.9% of patients remaining on MT. CONCLUSION This registry included the largest number of patients treated with TMVI to date. TMVI with 10 dedicated devices resulted in predictable MR elimination and sustained functional improvement at 1 year. In TMVI-ineligible patients, bailout-TEER and high-risk surgery represented reasonable alternatives, while MT was associated with poor clinical and functional outcomes.

Abstract
OBJECTIVES Minimally invasive mitral valve repair (MVR) promises major advantages over median sternotomy regarding cosmetic results and faster recovery. However, the long-term functional outcome of minimally invasive MVR has been questioned by critics because the limited access may not exclusively promise high-quality repair. This study examines the long-term outcome regarding survival and reoperation rate. METHODS All patients undergoing minimally invasive MVR from February 2000 until March 2020 were included in this study. Baseline clinical and surgical characteristics were summarized from the internal database. Primary end points were survival and freedom from reoperation, analysed via Kaplan-Meier curves. Secondary end points were periprocedural complications after minimally invasive MVR and incidence for recurrent mitral regurgitation >II°. RESULTS A total of 1194 patients underwent minimally invasive MVR, in 17 cases mitral valve replacement was required. The mean age was 55.1 years [47.6; 62.7]. The successful minimally invasive repair rate was 97%. The 30-day mortality was 0.6%. Survival was 96.7% [standard deviation (SD): 5.8%], 91.6% (SD: 1.1%) and 80.0% (SD: 11.2%) at 5, 10 and 20 years. The incidence of reoperation was 4.4% (SD: 3.2%), 10.3% (SD: 7.4%) and 16.7% (SD : 7.4%) at 5, 10 and 20 years, respectively. Concomitant procedures such as tricuspid valve repair and modified Cryo-maze procedure were performed in 263 cases. CONCLUSIONS Minimally invasive MVR for degenerative mitral regurgitation is safe, shows excellent functional long-term results and is associated with low perioperative and late mortality.

Abstract
Various interventional and minimally invasive surgical approaches are currently available for the treatment of mitral valve pathologies. However, only a few of these options are applicable in patients with previously operated on mitral valves. In this case report, we provide detailed insight into the step-by-step guidance of a percutaneous transseptal transcatheter mitral valve-in-valve implant under cerebral protection in a patient with a deteriorated surgically implanted mitral bioprosthesis.

Abstract
Background Report the incidence and results of peri-operative extracorporeal membrane oxygenation (ECMO) and intra-aortic balloon pump (IABP) of patients undergoing mitral valve surgery (MVS) through right mini-thoracotomy (RT) and conventional full sternotomy (FS) for a period of 6 years from eleven tertiary Cardiac Surgery Institutes of GVM Care & Research Italia. Methods From January 2016 to November 2021, a total of 5901 consecutive patients underwent MVS through RT and FS. The primary outcome of the study was the mortality and incidence of low cardiac output syndrome (LCOS) treated with intra-aortic balloon pump (IABP) with or without inotropic support and the incidence of Postcardiotomy Cardiogenic Shock (PCS) treated with Veno-arterial (VA) Extracorporeal Membrane Oxygenation (ECMO) on patients undergoing mitral valve surgery (MVS) through right mini-thoracotomy (RT) versus conventional full sternotomy (FS). Results The mean age was 66 ± 15 years, 3389 patients underwent in RT approach 2512 in FS, 3081 (52%) patients were male and 2.3% had previous cardiac operations. Cardiopulmonary bypass time was 93 min for RT and 81 min for FS and cross clamp time 75 min for RT and 63 min for FS for mitral valve repair. Incidence of perioperative IABP for the treatment of low cardiac output was reported on 99 patients (1.6%), 51 for RT (1.5%), 35% used inotropic support (adrenaline and milrinone) and 48 in FS (1.9), 28% use inotropic support, 21 patients died after IABP (3 RT and 18 FS). Incidence of perioperative VA-ECMO for the PCS treatment was 13 and 4 with IABP, 9 RT (0.2%) and 4 FS approach (0.15%), 12 patients died after VA-ECMO. Conclusion Minimally invasive mitral valve surgery is a safe and reproducible approach associated with low mortality and morbidity. ECMO and IABP incidence for the treatment of PCS was 0.2% and for Low cardiac output syndrome (LCOS) was 1.6% in elective mitral valve surgery is very low. The patients that use the perioperative IABP in minimally invasive mitral valve surgery (MIMVS) trough RT reported a reduced mortality compared to FS in relation to the operative risk and surgical technique. Low incidence of VA-ECMO was found in RT and FS approach, only one patient survived after VA-ECMO after minimally invasive mitral valve surgery.

Abstract
OBJECTIVES Minimally invasive mitral valve surgery (MIMVS) has been performed increasingly for the past 2 decades; however, large comparative studies on short- and long-term outcomes have been lacking. This study aims to compare short- and long-term outcomes of patients undergoing MIMVS versus median sternotomy (MST) based on real-world data, extracted from the Netherlands Heart Registration. METHODS Patients undergoing mitral valve surgery, with or without tricuspid valve, atrial septal closure and/or rhythm surgery between 2013 and 2018 were included. Primary outcomes were short-term morbidity and mortality and long-term survival. Propensity score matching analyses were performed. RESULTS In total, 2501 patients were included, 1776 were operated through MST and 725 using an MIMVS approach. After propensity matching, no significant differences in baseline characteristics persisted. There were no between-group differences in 30-day mortality (1.1% vs 0.7%, P = 0.58), 1-year mortality (2.6% vs 2.1%, P = 0.60) or perioperative stroke rate (1.1% vs 0.6%, P = 0.25) between MST and MIMVS, respectively. An increased rate of postoperative arrhythmia was observed in the MST group (31.3% vs 22.4%, P < 0.001). A higher repair rate was found in the MST group (80.9% vs 76.3%, P = 0.04). No difference in 5-year survival was found between the matched groups (95.0% vs 94.3%, P = 0.49). Freedom from mitral reintervention was 97.9% for MST and 96.8% in the MIMVS group (P = 0.01), without a difference in reintervention-free survival (P = 0.30). CONCLUSIONS The MIMVS approach is as safe as the sternotomy approach for the surgical treatment of mitral valve disease. However, it comes at a cost of a reduced repair rate and more reinterventions in the long term, in the real-world.

Abstract
Background Macro-reentrant atrial tachycardias (MATs) are a common complication after cardiac valve surgery. The MAT types and the effectiveness of MAT ablation might differ after different valve surgery. Data comparing the electrophysiological characteristics and the ablation results of MAT post-tricuspid or mitral valve surgery are limited. Methods Forty-eight patients (29 males, age 56.1 ± 13.3 years) with MAT after valve surgery were assigned to tricuspid valve (TV) group (n = 18) and mitral valve (MV) group (n = 30). MATs were mapped and ablated guided by a three-dimensional navigation system. The one-year clinical effectiveness was compared in two groups. Results Nineteen MATs were documented in TV group, including 16 cavo-tricuspid isthmus (CTI)-dependent AFL and 3 other MATs at right atrial (RA) free wall, RA septum and left atrial (LA) roof. Thirty-nine MATs were identified in MV group, including15 CTI-dependent AFL, 8 RA free wall scar-related, 2 RA septum scar-related, 8 peri-mitral flutter, 3 LA roof-dependent, 2 LA anterior scar-related, and 1 right pulmonary vein-related MAT. Compared with TV group, MV group had significantly lower prevalence of CTI-dependent AFL (38.5% vs. 84.2%), higher prevalence of left atrial MAT (35.9 vs.5.3%) and higher proportion of patients with left atrial MAT (40 vs. 5.6%), P = 0.02, 0.01 and 0.01, respectively. The acute success rate of MAT ablation (100 vs. 93.3%) and the one-year freedom from atrial tachy-arrhythmias (72.2 vs. 76.5%) was comparable in TV and MV group. No predictor for recurrence was identified. Conclusion Although the types of MATs differed significantly in patients with prior TV or MV surgery, the acute and mid-term effectiveness of MAT ablation was comparable in two groups. Trial registration: This study was registered as a part of EARLY-MYO-AF clinical trial at the website ClinicalTrials. gov (NCT04512222).

Abstract
OBJECTIVE To investigate the safety and medium- and long-term efficacy of surgical radiofrequency ablation to treat atrial fibrillation during concomitant mitral valve surgery. METHODS From January 2014 to December 2018, 280 patients with mitral valve disease and the comorbidity of preoperative atrial fibrillation were recruited for the study. Among them, 130 patients received only mitral valve surgery (non-ablation group), and 150 patients were underwent surgical radiofrequency ablation for the atrial fibrillation during concomitant mitral valve surgery (ablation group). Among the 150 patients of the ablation group, 80 had biatrial ablation, and 70 had left atrial ablation. Under general anesthesia, median sternotomy was done on all patients and cardiopulmonary bypass was established through the ascending aorta and superior and inferior venae cavae. After aortic occlusion, patients in the ablation group underwent the ablation procedure with the Atricure® bipolar ablation device, using the Cox Maze Ⅲ procedure as a reference. In addition, the left atrial appendage was removed and electrocautery of the ligament of Marshall and Waterston's groove were performed in all Cox Maze cases. Following ablation, mitral valve replacement or repair was performed. All patients were given 200 mg oral amiodarone on the first day after surgery, for three times/d×7 d, which was followed by twice/d×7 d, and then oral amiodarone 200 mg/d was maintained till the end of 3 months after surgery (ablation group) or 12 months after surgery (non-ablation group). Patients were followed up at the intervals of 3 months, 6 months, 12 months, 2 years, 3 years, and 5 years after discharge. The follow-up service included standard 12-lead chest electrocardiogram (ECG) and 24-h dynamic ECG. The primary end point of the study was the time point of postoperative atrial fibrillation and the secondary endpoints were major cardiovascular events, death, and readmission due to heart failure. RESULTS The surgeries were successfully performed in all subjects of the study. A total of 30 patients were lost to follow-up within 5 years after operation (10.7% losses to follow-up), including 11 patients in the ablation group and 19 patients in the non-ablation group. The proportion of patients who did not have atrial fibrillation in the ablation group and the non-ablation group at 6 months, 12 months, 2 years, 3 years and 5 years after surgery was 83.3% and 27.7%, 72.7% and 20.8%, 66.0% and 15.4% 61.3% and 13.1%, and 43.3% and 10.8%, respectively, with the data from the two groups showing statistically significant difference ( P<0.001). The proportion of patients who did not have atrial fibrillation in the biatrial ablation and the left atrial ablation group at 6 months, 12 months, 2 years, 3 years and 5 years after surgery was 87.3% and 87.5%, 92.4% and 82.8%, 90.5% and 85.7%, 94.8% and 88.1%, and 75.5% and 69.4%%, respectively, with the data from the two groups showing no statistically significant difference ( P>0.05). However, the cumulative incidence of atrial fibrillation in the two groups showed statistically significant difference ( P<0.001). There were no deaths within 30 days after operation in either group. There was no significant difference in cerebrovascular accident, readmission for heart failure, pulmonary infection and mediastinal infection between the two groups within one year after operation ( P>0.05). However, the proportion of patients who had permanent pacemaker installed due to Ⅲ-degree atrioventricular block in the ablation group was higher than that in the non-ablation group ( P<0.05). The proportion of patients who required re-drainage due to delayed pericardial effusion in the ablation group was higher than that in the non-ablation group ( P<0.05). CONCLUSION In the group of patients who had modified Cox Maze procedure with bipolar ablation device to treat atrial fibrillation during concomitant mitral valve surgery, the maintenance rate of sinus rhythm after cardioversion was significantly higher than that in the non-ablation group. The surgery showed better safety and significantly better medium- and long-term outcomes. Left atrial ablation and biatrial ablation were both considered safe and effective surgical treatment for atrial fibrillation. Compared with the left atrial ablation group, the biatrial ablation group achieved better effects in restoring and maintaining sinus rhythm without an increase the incidence of perioperative complications.

Abstract
OBJECTIVES Papillary muscle rupture (PMR) is a rare but potentially fatal complication of acute myocardial infarction. The aim of this study was to analyse the patient characteristics and early outcomes of the surgical management of post-infarction PMR from an international multicentre registry. METHODS Patients underwent surgery for post-infarction PMR between 2001 through 2019 were retrieved from database of the CAUTION study. The primary end point was in-hospital mortality. RESULTS A total of 214 patients were included with a mean age of 66.9 (standard deviation: 10.5) years. The posteromedial papillary muscle was the most frequent rupture location (71.9%); the rupture was complete in 67.3% of patients. Mitral valve replacement was performed in 82.7% of cases. One hundred twenty-two patients (57%) had concomitant coronary artery bypass grafting. In-hospital mortality was 24.8%. Temporal trends revealed no apparent improvement in in-hospital mortality during the study period. Multivariable analysis showed that preoperative chronic kidney disfunction [odds ratio (OR): 2.62, 95% confidence interval (CI): 1.07-6.45, P = 0.036], cardiac arrest (OR: 3.99, 95% CI: 1.02-15.61, P = 0.046) and cardiopulmonary bypass duration (OR: 1.01, 95% CI: 1.00-1.02, P = 0.04) were independently associated with an increased risk of in-hospital death, whereas concomitant coronary artery bypass grafting was identified as an independent predictor of early survival (OR: 0.38, 95% CI: 0.16-0.92, P = 0.031). CONCLUSIONS Surgical treatment for post-infarction PMR carries a high in-hospital mortality rate, which did not improve during the study period. Because concomitant coronary artery bypass grafting confers a survival benefit, this additional procedure should be performed, whenever possible, in an attempt to improve the outcome.

Abstract
BACKGROUND We examined whether the early development of exercise-induced pulmonary hypertension (EIPH) and right ventricular dysfunction during exercise stress echocardiography (ESE) may predict clinical deterioration in so-called "asymptomatic" patients with primary, at least moderate mitral regurgitation (MR). METHODS 79 consecutive patients underwent a symptom-limited, graded ESE protocol on semi-supine bicycle at the beginning of the study. During the test, we assessed symptom development, test duration, and the following echocardiographic parameters: MR severity, maximum velocity of the tricuspid regurgitation jet (TR Vmax), pulmonary artery systolic pressure (PASP), and tricuspid annulus systolic excursion (TAPSE). All patients were then followed-up for at least 12 months for clinical end-points (heart failure-related symptoms requiring pharmaceutical therapy, heart failure hospitalization, and/or mitral valve surgery in case of refractory symptoms). RESULTS After 16 ± 4 months of follow-up, 75 patients completed the study; 26 of them achieved any clinical end-point and were classified as 'high-risk', while the rest (49 patients) were assigned to the 'low-risk' group. High-risk group showed significantly higher exercise-induced TR Vmax and PASP levels at maximum workload of ESE than low-risk counterparts (p<0.001). Based on receiver operating characteristic analysis, the early (within the first two stages of ESE or up to 50 W) steep rise of calculated PASP ≥51 mmHg (TR Vmax ≥3.4 m/s) had a 92.3% sensitivity and 100% specificity to predict clinical deterioration within the following year. That cut-off value seemed superior predictor than peak value of PASP at the end of ESE. TAPSE levels during ESE did not add prognostic value in our sample. CONCLUSION This is the first study demonstrating that the early development of EIPH has prognostic value in asymptomatic patients with primary at least moderate MR and may become a new valid determinant of mitral valve surgery. Additional larger prospective studies are needed to validate our findings.

Abstract
BACKGROUND Tricuspid valve repair for functional regurgitation is effectively performed with different annuloplasty devices. However, it remains unclear whether there are advantages associated with rigid rings compared to flexible bands. This prospective randomised study aimed to compare results of using a flexible band ring versus a rigid ring for functional tricuspid regurgitation in patients undergoing mitral valve surgery. METHODS A single-centre randomised study was designed to allocate patients with functional tricuspid regurgitation undergoing mitral valve surgery to be treated with a flexible band or rigid ring. These patients were analysed by echocardiographic follow-up. The primary outcome was freedom from recurrent tricuspid regurgitation at 12-months follow-up. Secondary outcomes were 30-day mortality, survival, freedom from tricuspid valve reoperation, right ventricular reverse remodelling, and rate of major adverse events. RESULTS A total of 308 patients were allocated to receive concomitant tricuspid valve annuloplasty with the flexible band or rigid ring. There was no between-group difference in freedom from recurrent tricuspid regurgitation: 97.3% in Rigid group (95% CI, 93.0-98.8) and 96.2% in the Flexible group (95% CI, 92.0-98.5) at 12-months follow-up (log-rank, p=0.261). Early mortality, survival, freedom from tricuspid valve reoperation, and global right ventricle systolic function were also comparable in both groups of patients. However, the flexible band had advantage in restoring regional right ventricle function (Doppler-derived systolic velocities of the annulus [S], tricuspid annular plane systolic excursion) at 12-months follow-up. CONCLUSION Both the rigid ring and flexible band offered acceptable outcomes for functional tricuspid regurgitation correction without significant differences, as assessed at 12-months follow-up.

Abstract
BACKGROUND Right ventricular (RV) impairment may have prognostic value in patients undergoing mitral valve surgery. It is unclear whether RV dysfunction predicts long-term mortality, especially in the era of minimally invasive mitral surgery. METHODS We performed a retrospective analysis of consecutive patients referred for conventional (via sternotomy) and minimally invasive mitral valve surgery (MIMVS) between 01 January 2013 and 29 August 2018 in a tertiary cardiac centre. We truncated follow-up times at 25 March 2020. RV impairment was defined by reduced RV longitudinal function (TAPSE <17 mm) and/or dilated basal RV diameter (RVD1 > 42 mm). Primary outcome was all-cause mortality. RESULTS The study cohort included 359 patients followed up for a median period of 4.2 (1.8) years. MIMVS approach was performed in 127 (35.4%) and conventional approach in 232 (64.6%) patients of whom 36 (28%) and 45 (19%), respectively, had RV impairment. EuroSCORE II was significantly higher in patients with RV impairment compared with patients with preserved RV function, irrespective of the surgical approach. Consequently, in both groups, patients with RV impairment had significantly higher mortality compared to patients with preserved RV function. RV impairment adjusted for EuroSCORE II predicted mortality in the whole cohort (HR 2.139, 95% CI 1.249-3.663) and in conventional approach (HR 2.361, 95% CI 1.249-4.465) in contrast to MIMVS (HR 1.570, 95% CI 0.493-4.997). CONCLUSION In this real world cohort, patients with RV impairment and/or dilation had reduced long-term survival following both conventional surgery and MIMVS. Patients should be referred to surgery prior to worsening of RV function.

Abstract
AIMS Severe mitral regurgitation (MR) following acute myocardial infarction (MI) is associated with high mortality rates and has inconclusive recommendations in clinical guidelines. We aimed to report the international experience of patients with secondary MR following acute MI and compare the outcomes of those treated conservatively, surgically, and percutaneously. METHODS AND RESULTS Retrospective international registry of consecutive patients with at least moderate-to-severe MR following MI treated in 21 centres in North America, Europe, and the Middle East. The registry included patients treated conservatively and those having surgical mitral valve repair or replacement (SMVR) or percutaneous mitral valve repair (PMVR) using edge-to-edge repair. The primary endpoint was in-hospital mortality. A total of 471 patients were included (43% female, age 73 ± 11 years): 205 underwent interventions, of whom 106 were SMVR and 99 PMVR. Patients who underwent mitral valve intervention were in a worse clinical state (Killip class ≥3 in 60% vs. 43%, P < 0.01), but yet had lower in-hospital and 1-year mortality compared with those treated conservatively [11% vs. 27%, P < 0.01 and 16% vs. 35%, P < 0.01; adjusted hazard ratio (HR) 0.28, 95% confidence interval (CI) 0.18-0.46, P < 0.01]. Surgical mitral valve repair or replacement was performed earlier than PMVR [median of 12 days from MI date (interquartile range 5-19) vs. 19 days (10-40), P < 0.01]. The immediate procedural success did not differ between SMVR and PMVR (92% vs. 93%, P = 0.53). However, in-hospital and 1-year mortality rates were significantly higher in SMVR than in PMVR (16% vs. 6%, P = 0.03 and 31% vs. 17%, P = 0.04; adjusted HR 3.75, 95% CI 1.55-9.07, P < 0.01). CONCLUSIONS Early intervention may mitigate the poor prognosis associated with conservative therapy in patients with post-MI MR. Percutaneous mitral valve repair can serve as an alternative for surgery in reducing MR for high-risk patients.

Abstract
Minimally invasive mitral valve surgery (MIMVS) has become the standard approach for mitral valve pathology in many centres. The anterolateral mini thoracotomy access is beneficial in reoperative surgery by avoiding repeat sternotomy associated risks. The aim of this study is to analyse the safety of this technique. All patients undergoing reoperative MIMVS between 2008 and 2019 were studied retrospectively. Primary endpoint was 30-day major complications and mortality; secondary outcome was long term survival, reoperation rate and rate of more than moderate recurrent regurgitation. 146 Patients underwent reoperative MIMVS with a mean age of 68 ± 8 years. The composite outcome of 30-day major complication and mortality was 29.5%. 30-Day mortality was 6.2% and stroke rate 3.4%. Survival for the whole cohort was 89.7 ± 2.5% at 1-year, 71.6 ± 4.3% at 5 year and 50.9 ± 5.9% at 8-year follow up. Cox regression analysis revealed reduced left ventricular function (HR 2.8; 95%CI 1.5 - 5.0), GFR < 60 (HR 2.1; 95%CI 1.2 - 3.7) and active endocarditis (HR 6.4; 95%CI 2.7 - 15.4) as variables associated with reduced long-term survival. The cumulative incidence of re-operation after mitral valve replacement was 11.3 ± 3.2% at 5-year and for repair 16.2 ± 7.5% at 5-year. The cumulative incidence of more than moderate recurrent regurgitation after mitral valve repair was 25.4 ± 9.0% at 3-year. Minimally invasive access in reoperative mitral valve surgery in the current study showed similar 30-day mortality and stroke rate compared to repeat sternotomy results reported in literature.

Abstract
Aims Unipolar voltage (UV) mapping is increasingly used for guiding ablative therapy of atrial fibrillation (AF) as unipolar electrograms (U-EGMs) are independent of electrode orientation and atrial wavefront direction. This study was aimed at constructing individual, high-resolution sinus rhythm (SR) UV fingerprints to identify low-voltage areas and study the effect of AF episodes in patients with mitral valve disease (MVD). Methods and results Intra-operative epicardial mapping (interelectrode distance 2 mm) of the right and left atrium, Bachmann’s bundle (BB), and pulmonary vein area was performed in 67 patients (27 male, 67 ± 11 years) with or without a history of paroxysmal AF (PAF). In all patients, there were considerable regional variations in voltages. UVs at BB were lower in patients with PAF compared with those without [no AF: 4.94 (3.56–5.98) mV, PAF: 3.30 (2.25–4.57) mV, P = 0.006]. A larger number of low-voltage potentials were recorded at BB in the PAF group [no AF: 2.13 (0.52–7.68) %, PAF: 12.86 (3.18–23.59) %, P = 0.001]. In addition, areas with low-voltage potentials were present in all patients, yet we did not find any predilection sites for low-voltage potentials to occur. Conclusion Even in SR, advanced atrial remodelling in MVD patients shows marked inter-individual and regional variation. Low UVs are even present during SR in patients without a history of AF indicating that low UVs should carefully be used as target sites for ablative therapy.

Abstract
OBJECTIVES Conduction disturbances requiring permanent pacemaker (PPM) implantation remain a complication following valvular surgery. PPMs confer the risk of infection, tricuspid valve regurgitation and pacing-induced cardiomyopathy. Literature examining PPM placement in mitral valve surgery (MVS) is limited. METHODS Our institutional mitral valve (MV) database was retrospectively reviewed for adult patients undergoing surgery from 2011 to 2019. Patients with preoperative PPM were excluded. Patients were stratified by the receipt of PPM following their index operations. Multivariable logistic regression was performed to determine patient and operative risk factors for PPM. Subgroup analysis was performed on patients who underwent isolated MVS. Kaplan-Meier analysis and a multivariable Cox proportional hazards model were utilized to assess the association between PPM implantation and long-term survival. RESULTS A total of 3391 (2991 non-PPM and 400 PPM) patients met the study criteria. Significant predictors of PPM included increased decade of age (odds ratio: 1.23; 95% confidence interval: 1.12-1.35), concomitant aortic (1.44; 1.10-1.90) and tricuspid valve procedures (2.21; 1.64-2.97) and prior history of myocardial infarction (1.48; 1.07-1.86). In the isolated MV repair population, annuloplasty with ring prosthesis was associated with PPM (3.09; 1.19-8.02). Patients in the replacement population did not have significant identifiable risk factors. There was no survival difference found, and postoperative PPM placement was not found to be an independent predictor of mortality. CONCLUSIONS Our primary aim was to elucidate predictors for PPM implantation in MVS and found increasing age and concomitant procedures to be risk factors. Receipt of PPM is associated with worse long-term survival but does not independently predict survival. Among patients undergoing isolated MV repair, use of an annuloplasty ring confers a higher risk of PPM compared to an annuloplasty band.

Abstract
OBJECTIVES Although indications for the MitraClip are becoming increasingly liberal, the number of patients requiring valve surgery after an insufficient outcome of the procedure is growing. Referral to surgery is, however, frequently delayed. During this time, the patients often deteriorate. We retrospectively analysed patients before MitraClip implantation and after mitral valve surgery. METHODS A total of 49 patients who received a mitral valve replacement (average 8 ± 12 months after MitraClip implantation) were assessed. Of these, 53% had 2-4 clips inserted. The mean age was 73 years, and the mean log EuroSCORE was 20.79 ± 14.42%. Echocardiographic data obtained prior to MitraClip implantation and preoperatively, 10 days and 6 and 12 months after cardiac surgery were reviewed. Survival analysis, risk profile and postoperative complications were analysed. RESULTS The 30-day and 1-year mortality was 26.5% and 59.2%, respectively. Prior to MitraClip implantation, 42.8% of patients had mild tricuspid insufficiency and 6.1% had moderate tricuspid insufficiency. Prior to surgery, 26.5% showed mild, 32.7% moderate and 38.8% severe tricuspid insufficiency (P < 0.001). Furthermore, right heart function assessed by tricuspid annular plane systolic excursion deteriorated significantly after Implantation of the MitraClip (P < 0.001). In patients with a MitraClip, the pulmonary artery pressure was significantly higher at the time of mitral replacement than it was before the MitraClip was implanted (P < 0.001). CONCLUSIONS A subgroup of patients does not benefit from a MitraClip and shows progressive deterioration in cardiac function, making valve replacement under difficult circumstances inevitable. The earlier these patients are operated on, the better it is. It can be assumed that some patients would be better off with primary surgery, especially if mitral reconstruction is then still feasible. Therefore, the indications for MitraClip implantation should be carefully considered and caution should be exercised during monitoring.

Abstract
Aims The morphology of unipolar single potentials (SPs) contains information on intra-atrial conduction disorders and possibly the substrate underlying atrial fibrillation (AF). This study examined the impact of AF episodes on features of SP morphology during sinus rhythm (SR) in patients with mitral valve disease. Methods and results Intraoperative epicardial mapping (interelectrode distance 2 mm) of the right and left atrium (RA, LA), Bachmann’s bundle (BB), and pulmonary vein area (PVA) was performed in 67 patients (27 male, 67 ± 11 years) with or without a history of paroxysmal AF (PAF). Unipolar SPs were classified according to their differences in relative R- and S-wave amplitude ratios. A clear predominance of S-waves was observed at BB and the RA in both the no AF and PAF groups (BB 88.8% vs. 85.9%, RA 92.1% vs. 85.1%, respectively). Potential voltages at the RA, BB, and PVA were significantly lower in the PAF group (P < 0.001 for each) and were mainly determined by the size of the S-waves amplitudes. The largest difference in S-wave amplitudes was found at BB; the S-wave amplitude was lower in the PAF group [4.08 (2.45–6.13) mV vs. 2.94 (1.40–4.75) mV; P < 0.001]. In addition, conduction velocity (CV) at BB was lower as well [0.97 (0.70–1.21) m/s vs. 0.89 (0.62–1.16) m/s, P < 0.001]. Conclusion Though excitation of the atria during SR is heterogeneously disrupted, a history of AF is characterized by decreased SP amplitudes at BB due to loss of S-wave amplitudes and decreased CV. This suggests that SP morphology could provide additional information on wavefront propagation.

Abstract
![]()
OBJECTIVES Posterior ventricular anchoring neochordal (PVAN) repair is a non-resectional technique for correcting mitral regurgitation (MR) due to posterior leaflet prolapse, utilizing a single suture anchored in the myocardium behind the leaflet. This technique has demonstrated clinical efficacy, although a theoretical limitation is stability of the anchoring suture. We hypothesize that the PVAN suture positions the leaflet for coaptation, after which forces are distributed evenly with low repair suture forces. METHODS Porcine mitral valves were mounted in a 3-dimensional-printed heart simulator and chordal forces, haemodynamics and echocardiography were collected at baseline, after inducing MR by severing chordae, and after PVAN repair. Repair suture forces were measured with a force-sensing post positioned to mimic in vivo suture placement. Forces required to pull the myocardial suture free were also determined. RESULTS Relative primary and secondary chordae forces on both leaflets were elevated during prolapse (P < 0.05). PVAN repair eliminated MR in all valves and normalized chordae forces to baseline levels on anterior primary (0.37 ± 0.23 to 0.22 ± 0.09 N, P < 0.05), posterior primary (0.62 ± 0.37 to 0.14 ± 0.05 N, P = 0.001), anterior secondary (1.48 ± 0.52 to 0.85 ± 0.43 N, P < 0.001) and posterior secondary chordae (1.42 ± 0.69 to 0.59 ± 0.17 N, P = 0.005). Repair suture forces were minimal, even compared to normal primary chordae forces (0.08 ± 0.04 vs 0.19 ± 0.08 N, P = 0.002), and were 90 times smaller than maximum forces tolerated by the myocardium (0.08 ± 0.04 vs 6.9 ± 1.3 N, P < 0.001). DISCUSSION PVAN repair eliminates MR by positioning the posterior leaflet for coaptation, distributing forces throughout the valve. Given extremely low measured forces, the strength of the repair suture and the myocardium is not a limitation.

Abstract
BACKGROUND Isolated tricuspid valve (TV) surgery is associated with markedly worse outcomes than isolated mitral valve (MV) surgery. We hypothesized that this is related to late referral of patients with isolated TV disease. METHODS Adult patients who underwent isolated TV or MV surgery in 2016-2017 were identified in the National-Readmission-Database. We compared the outcomes of isolated TV and MV surgery before and after adjustment for surrogates of late referral. RESULTS A total of 21,446 patients who had isolated MV (n = 19,933), or TV surgery (n = 1153) were included. Patients in the TV group were younger (55.7 ± 16.6 vs. 63.4 ± 12.3 years), had lower socioeconomic status, but higher prevalence of surrogates for late referral [acute HF 41.0% vs. 22.0%, advanced liver disease 16.8% vs. 2.6%, non-elective surgery status 44.3% vs. 23.5%, need for peri-operative mechanical circulatory support 27.7% vs. 4.7%, and unplanned admissions in the 90 days before surgery 31.0% vs. 18.8%, (P < 0.001 for all)]. Surgery was performed on day 0/1 of the admission in 80% of patients in the MV group and 52% in the TV group, P < 0.001. Repair rate was 63.5% in the TV group and 56.3% in the MV group (P < 0.001). In-hospital mortality was 3-folds higher after TV surgery (8.7% vs. 2.5%; OR = 3.41, 95%CI 2.73-4.25, p < 0.001). However, this difference became non-significant after adjusting for baseline characteristics including surrogates for late referral (OR = 1.24, 95%CI 0.85-1.82, p = 0.27). CONCLUSION The poor outcomes of isolated TV surgery compared with isolated MV surgery may be largely explained by the late referral for intervention in patients with isolated TR.

Abstract
Patients with mitral valve prolapse (MVP), undergoing early surgery for severe regurgitation, are usually characterized by a low degree of right chambers' remodeling. In this selected population, the mechanisms leading to tricuspid annular (TA) dilatation (TAD) are not well understood. In this setting, we aimed to evaluate, using three-dimensional echocardiography (3DE), how right chambers affect TA size and might contribute to functional tricuspid regurgitation (FTR) progression. We studied 159 patients treated with early isolated surgery for MVP, characterized by: sinus rhythm; normal biventricular function; normal or elevated pulmonary artery pressure; tricuspid regurgitation (TR) ≤ mild; no concomitant cardiac disease. All patients reached a 3-year echocardiographic follow-up. Based on two-dimensional echocardiography, patients were divided in Group 1 (N = 68, 43%, TAD, TA ≥ 21 mm/m2) and Group 2 (N = 91, 57%, no TAD, TA < 21 mm/m2). By 3DE, Group 1 showed larger TA size, right atrial (RA) volume and right ventricular (RV) conical remodeling compared to Group 2 (p < 0.05). The multivariate analysis revealed that RA volume, RV basal diameter and function were independently correlated to TA size (p < 0.05). At the 3-year follow-up there was a low incidence of FTR, with a trend towards FTR progression in Group 1 (p = 0.07). In patients undergoing early surgery for MVP, TAD seems to result from distinctive early-onset geometrical changes of the right chambers, preceding TR, RV dilatation and pulmonary hypertension at rest. An integrated approach, including right chambers' assessment by 3DE, might help to better recognized patients at higher risk for TAD and, potentially for FTR.
