Abstract
OBJECTIVE Atrial fibrillation (AF), if left untreated, is associated with increased intermediate and long-term morbidity/mortality. Surgical treatment for AF is lacking standardization in patient selection and lesion set, despite clear support from multi-society guidelines. The aim of this study was to analyze a statewide cardiac surgery registry to establish whether or not there is an association between center volume and type of index procedure with performance of surgical ablation (SA) for AF, the lesion set chosen, and ablation technology used. METHODS Adult, first-time, nonemergency patients with preoperative AF between 2014 and 2022 excluding standalone SA procedures from a statewide registry of Society of Thoracic Surgeons data were included (N = 4320). AF treatment variability by hospital volume (ordered from smallest to largest) and surgery type were examined with χ2 analyses. Hospital-level Spearman correlations compared hospital volume with proportion of AF patients treated with SA. RESULTS Overall, 37% of patients with AF were ablated at the time of surgery (63% of mitral procedures, 26% of non-mitrals) and 15% had left atrial appendage management only. There was a significant temporal trend of increasing performance of SA for AF over time (Cochran-Armitage = 27.8; P < .001). Hospital cardiac surgery volume did not correlate with the proportion of AF patients treated with SA (rs = 0.19; P = .603) with a rate of SA below the state average for academic centers. Of cases with SA (n = 1582), only 43% had a biatrial lesion set. Procedures that involved mitral surgery were more likely to include a biatrial lesion set (χ2 = 392.3; P < .001) for both paroxysmal and persistent AF. Similarly, ablation technology use was variable by type of concomitant operation (χ2 = 219.0; P < .001) such that radiofrequency energy was more likely to be used in non-mitral procedures. CONCLUSIONS These results indicate an increase in adoption of SA for AF over time. No association between greater hospital volume or academic status and performance of SA for AF was established. Similar to national data, the type of index procedure remains the most consistent factor in the decision to perform SA with a disconnect between AF pathophysiology and decision making on the type of SA performed. This analysis demonstrates a gap between evidence-based guidelines and real-world practice, highlighting an opportunity to confer the benefits of concomitant SA to more patients.

Abstract
OBJECTIVE Minimally invasive cardiac surgery (MICS) is increasing worldwide. In most cases, the surgical technique includes cannulation of the groin for the establishment of cardiopulmonary bypass, requiring a second surgical incision (SC) for exposure and cannulation of the femoral vessels. With the introduction of arterial closure devices, percutaneous cannulation (PC) of the groin has become a possible alternative. We performed a meta-analysis and systematic review to compare clinical endpoints between the patients who underwent PC and SC for MICS. METHODS Three databases were assessed. The primary outcome was any access site complication. Secondary outcomes were perioperative mortality, any wound complication, any vascular complication, lymphatic complications, femoral/iliac stenosis, stroke, procedural duration, and hospital length of stay (LOS). A random effects model was performed. RESULTS A total of 5 studies with 2,038 patients were included. When compared with PC, patients who underwent SC showed a higher incidence of any access site complication (odds ratio [OR] = 3.09, 95% confidence interval [CI]: 1.87 to 5.10, P < 0.01), any wound complication (OR = 10.10, 95% CI: 3.31 to 30.85, P < 0.01), lymphatic complication (OR = 9.37, 95% CI: 2.15 to 40.81, P < 0.01), and longer procedural duration (standardized mean difference = 0.31, 95% CI: 0.12 to 0.51, P < 0.01). There was no significant difference between the 2 groups regarding perioperative mortality, any vascular complication, femoral/iliac stenosis, stroke, or hospital LOS. CONCLUSIONS The analysis suggests that surgical groin cannulation in MICS is associated with a higher incidence of any access site complication (especially wound complication and lymphatic fistula) and with a longer procedural time compared with PC. There was no difference in perioperative mortality.

Navigating the challenges of minimally invasive mitral valve surgery: a risk analysis and learning curve evaluation. J Cardiothorac Surg 2024; 19:24. [PMID: 38263168 PMCID: PMC10807125 DOI: 10.1186/s13019-024-02479-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Accepted: 01/10/2024] [Indexed: 01/25/2024] Open
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
The adoption of minimally invasive mitral valve surgery (MIMVS) has become a prominent trend in mitral valve procedures. This article emphasizes that the success of the MIMVS program relies not only on effective teamwork but also on comprehensive hospital support and a clearly defined training strategy. Additionally, targeted marketing initiatives that highlight the value of the heart valve centre are crucial for sustaining the program's success and attracting a consistent patient flow. The implementation of these strategies requires diligent execution, consistent maintenance, and continuous improvement to ensure the triumph of the MIMVS program. This article aims to share our experience in implementing MIMVS at our centre, providing valuable insights for centres that have yet to adopt this approach or have low adoption rates. While acknowledging that sharing our centre's experience cannot guarantee success in all centres, customizing the implementation by selecting appropriate features and access points is vital. Each centre may encounter unique challenges, and tailoring the strategy to address specific needs will enhance the effectiveness of the MIMVS program.

Abstract
BACKGROUND The adoption of minimally invasive techniques to perform mitral valve repair surgery is increasing. This is enhanced by the compelling evidence of satisfactory short-term results and lower major morbidity. We analyzed mid-term follow-up results of our experience, and further compared two techniques: isolated leaflet resection and neochord implantation for posterior leaflet prolapse. METHODS Data for all consecutive endoscopic mitral valve repairs via video-assisted right anterior mini-thoracotomy were analyzed between December 2012 and September 2021. The early and mid-term follow-up results were ascertained. The main outcome was the incidence of mortality and the recurrence of significant mitral regurgitation during follow-up which were summarized by the Kaplan-Meier estimator and compared between treatment arms using the stratified log-rank test. Secondary outcomes were the early-postoperative results including 30-days mortality and the occurrence of major complications. RESULTS A total of 309 patients were included. Along with ring annuloplasty, 136 (44.4%) patients received posterior leaflet resection (122 isolated) whereas 97 (31.1%) underwent posterior leaflet chords implantation (88 isolated). Forty-nine patients had annuloplasty alone. In-hospital mortality was 1.0%. Mean follow-up was 28.8 ± 22.0 months (maximum 8.3 years). Kaplan-Meier survival rate at 5 years was 97.3 ± 1.0%, mitral regurgitation ([Formula: see text]3+) or valve reoperation free-survival at 5 years was estimated as 94.5 ± 2.3%. Subgroup time-to-event analysis for the indexed outcomes showed no statistical significance between the techniques. CONCLUSIONS Endoscopic mitral valve repair is safe and associated with excellent short- and mid-term outcomes. No differences were found between leaflet resection and gore-tex chords implantation for posterior leaflet prolapse.

Abstract
Importance The safety and effectiveness of mitral valve repair via thoracoscopically-guided minithoracotomy (minithoracotomy) compared with median sternotomy (sternotomy) in patients with degenerative mitral valve regurgitation is uncertain. Objective To compare the safety and effectiveness of minithoracotomy vs sternotomy mitral valve repair in a randomized trial. Design, Setting, and Participants A pragmatic, multicenter, superiority, randomized clinical trial in 10 tertiary care institutions in the UK. Participants were adults with degenerative mitral regurgitation undergoing mitral valve repair surgery. Interventions Participants were randomized 1:1 with concealed allocation to receive either minithoracotomy or sternotomy mitral valve repair performed by an expert surgeon. Main Outcomes and Measures The primary outcome was physical functioning and associated return to usual activities measured by change from baseline in the 36-Item Short Form Health Survey (SF-36) version 2 physical functioning scale 12 weeks after the index surgery, assessed by an independent researcher masked to the intervention. Secondary outcomes included recurrent mitral regurgitation grade, physical activity, and quality of life. The prespecified safety outcomes included death, repeat mitral valve surgery, or heart failure hospitalization up to 1 year. Results Between November 2016 and January 2021, 330 participants were randomized (mean age, 67 years, 100 female [30%]); 166 were allocated to minithoracotomy and 164 allocated to sternotomy, of whom 309 underwent surgery and 294 reported the primary outcome. At 12 weeks, the mean between-group difference in the change in the SF-36 physical function T score was 0.68 (95% CI, -1.89 to 3.26). Valve repair rates (≈ 96%) were similar in both groups. Echocardiography demonstrated mitral regurgitation severity as none or mild for 92% of participants at 1 year with no difference between groups. The composite safety outcome occurred in 5.4% (9 of 166) of patients undergoing minithoracotomy and 6.1% (10 of 163) undergoing sternotomy at 1 year. Conclusions and relevance Minithoracotomy is not superior to sternotomy in recovery of physical function at 12 weeks. Minithoracotomy achieves high rates and quality of valve repair and has similar safety outcomes at 1 year to sternotomy. The results provide evidence to inform shared decision-making and treatment guidelines. Trial Registration isrctn.org Identifier: ISRCTN13930454.

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
OBJECTIVE This study evaluated the ergonomics and time requirements of using a novel automated suturing and titanium fastener deployment technology for chordal replacement in human heart specimens in open and minimally invasive cardiac surgery (MICS) simulators. METHODS Five cardiac surgeons used novel, manually powered expanded polytetrafluoroethylene (ePTFE) suturing devices to automate suture placement between mitral leaflets and papillary muscles in explanted cadaver hearts, along with customized titanium fastener delivery devices to secure suture and trim suture tails. This mitral chordal replacement test was conducted using surgical models simulating open and MICS mitral repair access. The study was approved by the institutional ethical board. RESULTS After a brief introduction to this technique using plastic models, study surgeons performed 48 chordal replacements in human mitral valves, placing 18 in an open model and 30 in a right minithoracotomy model. The time range to complete a single chordal replacement was between 55 s and 8 min, with an overall mean duration of 3.6 ± 1.5 min. No difference in duration of implantation was recorded for the MICS and open sternotomy simulators used. Good control of suture delivery was reported in 95.8% (n = 46) of leaflet aspect of the sutures and in 100% (N = 48) of papillary muscle sutures. CONCLUSIONS Automated mitral chordal ePTFE suturing simulated through open and MICS access demonstrated quality handling and accurate placement of sutures in human heart specimens. A clinical trial using this technology is currently ongoing. This innovation may present an important advance facilitating enhanced minimally invasive mitral valve repair.

Abstract
Minimally invasive mitral valve surgery is evolving rapidly since the early 1990’s and is now increasingly adopted as the standard approach for mitral valve surgery. It has a long and challenging learning curve and there are many considerations regarding technique, planning and patient selection when starting a minimally invasive program. In the current review, we provide an overview of all considerations and the decision-making process during the learning curve.

Abstract
BACKGROUND Although transcatheter edge-to-edge repair (TEER) is effective and safe, there is a need for better prediction of optimal outcomes. We aimed to determine predictors of optimal reduction in mitral regurgitation (MR) and survival with TEER. METHODS We examined mitral anatomy and its change with TEER on outcomes in 183 patients (age, 82 [77-87] years; 53% women). Coaptation reserve was measured as the distance of continuous apposition of the A2 and P2 leaflet segments in 2-dimensional apical long-axis imaging at the site of the predominant jet of MR. Augmentation in coaptation was measured as the total amount of leaflet insertion. Addressable coaptation area was calculated using the physical boundaries of the TEER device. RESULTS Coaptation reserve, its augmentation, and addressable coaptation area were strong predictors of MR reduction (all P<0.001), as well as heart failure hospitalization and death. For patients with either mild or no residual MR, median values for coaptation reserve, its augmentation, and addressable coaptation area were 3.7 (2.8-4.5) mm, 7.3 (5.2-9.5) mm, and 59.0 (48.0-71.8) mm2, respectively. Receiver operating characteristic analyses determined the best values for optimal MR reduction as a coaptation reserve of >3.0 mm (P<0.001), addressable coaptation area of ≥52 mm2 (P<0.001), and coaptation augmentation of ≥4.7 mm (P<0.001). These values were associated with greater 2-year survival free of all-cause mortality and persisting even in analyses restricted to those with mild or no residual MR after TEER. CONCLUSIONS Coaptation reserve and its augmentation are simple, independent parameters that predict optimal MR reduction and better survival in patients undergoing TEER. These findings may have implications for patient selection and expanded use of the therapy.

Abstract
Consistent evidence recognizes minimally invasive valve surgery as the top-tier surgical approach for heart valve pathology. Conversely, the overall adoption of minimally invasive coronary surgery remains low. Notwithstanding, excellent clinical outcomes have been recently reported, further consolidating a technique that addresses major concerns associated with the traditional approach for the most frequently performed cardiac operation, including sternal dehiscence (i.e., sternal sparing), stroke (i.e., no-touch aorta), but that also guarantees a reduced resort to blood transfusions, diminished pain, and faster recovery. More to the point, the suitability of minimally invasive strategies for combined coronary and valve procedures remains debatable. Almost no reports of such combined procedures are available in literature and the very few published experiences appear scarce and heterogeneous about the surgical access (i.e., single versus bilateral mini-thoracotomy). However, bilateral mini-thoracotomy has been proposed as a feasible and safe strategy for different cardiac operations like surgical ablation and left ventricular assist device implantation, but also for isolated multivessel minimally invasive coronary surgery. Here we describe feasibility of combined minimally invasive mitral valve and coronary surgery performed through bilateral mini-thoracotomy and we report outcomes of our initial series of 3 cases.

Abstract
OBJECTIVE Up to 28% of patients may need mitral valve (MV) surgery after transcatheter edge-to-edge repair (TEER). This study evaluates the outcomes of minimally invasive MV surgery after TEER. Methods: International multicenter registry of minimally invasive MV surgery after TEER between 2013 and 2020. Subgroups were stratified by the number of devices implanted (≤1 vs >1), as well as time interval from TEER to surgery (≤1 year vs >1 year). Results: A total of 56 patients across 13 centers were included with a mean age of 73 ± 11 years, and 50% were female. The median Society of Thoracic Surgeons Predicted Risk of Mortality (STS PROM) score for MV replacement was 8% (Q1-Q3 = 5% to 11%) and the ratio of observed to expected mortality was 0.9. The etiology of mitral regurgitation (MR) prior to TEER was primary MR in 75% of patients and secondary MR in 25%. There were 30 patients (54%) who had >1 device implanted. The median time between TEER and surgery was 252 days (33 to 636 days). Hemodynamics, including MR severity, MV area, and mean gradient, significantly improved after minimally invasive surgery and sustained to 1-year follow-up. In-hospital and 30-day mortality was 7.1%, and 1-year actuarial survival was 85.6% ± 6%. Conclusions: Minimally invasive MV surgery after TEER may be achieved as predicted by the STS PROM. Most patients underwent MV replacement instead of repair. As TEER is applied more widely, patients should be informed about the potential need for surgical intervention over time after TEER. These discussions will allow better informed consent and post-procedure planning.

Abstract
BACKGROUND The durability of surgical repair for degenerative versus ischemic mitral regurgitation (MR) is thought to be markedly different. We, therefore, examined late outcomes and durability for mitral repair in a large cohort of patients receiving a single annuloplasty device. METHODS A total of 749 consecutive patients receiving mitral repair for degenerative mitral regurgitation (DMR) or ischemic mitral regurgitation (IMR) were evaluated from a prospective database. Patients with tricuspid or maze surgery were included. Papillary muscle rupture and mixed valve etiologies were excluded. Outcomes were compared for IMR versus DMR. RESULTS Patients with DMR were younger and less urgent. Patients with IMR had mean end-systolic diameter 4.5 ± 1.1 cm. All patients received the same complete semirigid annuloplasty device with median ring size 32 mm for DMR and 24 mm for IMR. New York Heart Association failure class improved from 2.8 to 1.5 (p < .001). Patients with DMR had lower operative mortality (1/384 [0.3%] vs. 26/365 [7%], p < .0001) and shorter length of stay. A 15-year survival was better with DMR (63% ± 3% vs. 13% ± 2%, p < .001). At 10 years, the incidence of recurrent ≥2+ MR (10% ± 2% vs. 16% ± 2%, p = .16) was not significantly different. Predictors of recurrent ≥2+ MR were female gender (odds ratio [OR]: 3.0 (1.9-4.8, p < .0001), and prior operation (OR: 2.4 [1.3-4.5], p = .02) but not IMR (OR: 1.4 [0.9-2.3], p = .15). CONCLUSIONS In this series, where patients with IMR had relatively preserved ventricular dimensions, the primary determinants of late recurrent MR were female gender and prior operation but not IMR versus DMR. Selected patients with IMR can obtain relatively durable mitral repair despite higher operative risk and lower survival compared to DMR.

Abstract
BACKGROUND Concerns regarding long-term durability of surgical repair for functional mitral regurgitation are based on short-term data, with few comparisons of ischemic (IMR) versus non-ischemic (NIFMR) etiology. METHODS 788 consecutive patients receiving mitral repair for functional mitral regurgitation were evaluated from a prospectively maintained database. Patients with other surgical procedures were included. Propensity score matching was used to compare outcomes in IMR versus NIFMR. RESULTS Unmatched IMR patients tended to be older men with greater comorbidities. 198 matched pairs of IMR versus NIFMR patients had similar demographics with relatively preserved ejection fraction 40±13% and end-systolic diameter 4.3±1.1cm. Concomitant coronary revascularization occurred in 70% of matched IMR patients. All patients received an annuloplasty ring, usually 24-26 mm. Heart failure class improved from 2.8 preop to 1.5 at 5 years (P<0.0001). Survival at 15 years was worse with IMR (12±3% v 43±5%, P<0.0001). At 10 years, cumulative incidence of moderate or more (>=2+) mitral regurgitation (27±4% v 26±4%, P=0.4), severe regurgitation (10±3% v 8±2%, P=0.5), and mitral reoperation (3±1% v 3±1%, P=0.4) were not different between IMR v NIFMR. Recurrent moderate regurgitation was associated with heart failure readmission but not with mortality. CONCLUSIONS In propensity-matched patients, IMR versus NIFMR had worse survival but similar repair durability, with moderate regurgitation in 27% at 10 years and rare severe regurgitation or mitral reoperation. In selected patients with relatively preserved function, mitral repair for IMR or NIFMR can improve symptoms with durable mild regurgitation in most patients out to 10 years.

Abstract
Introduction: During the past five years the approach to procedural planning, operative techniques and perfusion strategies for minimally invasive mitral valve surgery (MIMVS) has evolved. With the goal to provide a maximum of patient safety the procedure has been modified according to individual patient characteristics and is largely based on preoperative imaging.Areas covered: In this review article we describe the important factors in image based therapy planning and simulation, different access strategies, the operative key-steps, a rationale use of devices, and highlight a few future developments in the field of MIMVS. Published studies were identified through pearl growing, citation chasing, a search of PubMed using the systematic review methods filter, and the authors' topic knowledge.Expert opinion: With the help of expert teams including surgeons specialized in mitral repair, anesthesiologists and perfusionists a broad spectrum of mitral valve pathologies and related pathologies can be treated with excellent functional outcomes. Avoiding procedure related complications is the key for success for any MIMVS program.
