Outcome Prediction score for mitral transcatheter edge-to-edge repair in patients with concomitant significant tricuspid regurgitation. Hellenic J Cardiol 2024; 78:3-15. [PMID: 37696418 DOI: 10.1016/j.hjc.2023.09.006] [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: 07/01/2023] [Revised: 09/01/2023] [Accepted: 09/05/2023] [Indexed: 09/13/2023] Open
Abstract
BACKGROUND Tricuspid regurgitation (TR) adversely affects prognosis following mitral transcatheter edge-to-edge repair (TEER). We aimed to derive a risk stratification tool for patients undergoing TEER for mitral regurgitation while exhibiting significant TR. METHODS This is a single-center, retrospective analysis of 217 consecutive individuals referred to an isolated mitral TEER who had moderate-to-severe or greater TR at baseline. The primary outcome was the 1-year composite of all-cause mortality or heart failure hospitalizations. The cohort was randomly split in a 75%-to-25% ratio, creating train (n = 163) and test (n = 54) datasets. Model development, discrimination, and calibration were based on the train dataset. Internal validation was applied to the test dataset. RESULTS Overall, 81 (37.3%) patients experienced the primary outcome. After multivariable analysis, a score for predicting the primary outcome was constructed that utilized a 0-to-3 scale, in which each point represented one of three baseline variables independently associated with this combined endpoint: serum B-natriuretic peptide (BNP) level >1,000 pg/mL, qualitative right ventricular (RV) dysfunction on transthoracic echocardiogram, and cardiac implantable electronic device (CIED). C-statistic of the model was 0.66 (95% CI, 0.57-0.75, p = 0.002) and 0.75 (95% CI, 0.61-0.89, p = 0.004) in the train and test datasets, respectively-representing comparable performance to current, more complex tools. Neither this BNP-RV-CIED (BRC) score nor other models were prognostically meaningful in 32 patients excluded from the main analysis who underwent a combined mitral-tricuspid TEER. CONCLUSION The BRC score is a simple clinical prediction tool that may aid in the triage of isolated mitral TEER candidates with significant pre-existing TR.

Abstract
Although existing guidelines offer strong recommendations for single valvular dysfunction, the growing prevalence of multiple valvular heart disease (MVHD) in our aging population is challenging the clarity of clinical guidance. Traditional diagnostic modalities, such as echocardiography, face inherent constraints in precisely quantifying valvular dysfunction due to the hemodynamic interactions that occur with multiple valve involvement. Therefore, many patients with MVHD present at a later stage in their disease course and with an elevated surgical risk. The expansion of transcatheter therapy for the treatment of valvular heart disease has added new opportunities for higher-risk patients. However, the impact of isolated valve therapies on patients with MVHD is still not well understood. This review focuses on the etiology, diagnostic challenges, and therapeutic considerations for some of the most common concomitant valvular abnormalities that occur in our daily clinic population.

Abstract
Treatment for mixed valve disease has historically been limited, often surgery being the only option. With the recent advancement of transcatheter therapies, percutaneous approaches are quickly becoming viable therapeutic considerations in inoperable or high-risk patients, also offering the option for a staged or same-session treatment. Guidelines are primarily focused on single-valve disease. However, patients often present with multiple pathologies. This review summarizes the data and literature on transcatheter treatment of patients with mitral regurgitation who concomitantly have aortic stenosis or regurgitation, tricuspid regurgitation, or ischemic cardiomyopathy. Pathophysiology, hemodynamics, available therapies as well as order and timing of interventions are discussed.

Abstract
Tricuspid valve regurgitation (TR) is becoming increasingly more clinically important. While considered as an accompanying symptom of left heart pathologies in the past, TR is now seen as an independent and clinically significant condition. TR can lead to volume overload of the right ventricle, resulting in dilatation of the tricuspid valve annulus and worsening of the regurgitation. Undetected or untreated severe TR can lead to recurrent cardiac decompensation with hospitalization, reduced quality of life and death. Previous treatment options were limited to cardiac surgery and associated with high complication and mortality rates, especially in isolated TR. Therefore, many patients are considered inoperable so that the new interventional treatment measures nowadays often represent the only treatment option. Interventional treatment options such as the edge-to-edge procedure (T-TEER) with TriClip™ or the PASCAL™ system are very safe interventions that have already shown promising results, including reduction of TR, improvement in heart failure symptoms and the quality of life. The influence on the mortality and the necessity for hospitalization due to heart failure are currently being investigated in several randomized studies. Patient selection and timing of the intervention are crucial. Cardiovascular imaging plays a decisive role in selecting the appropriate method and timing of the intervention. The prognosis depends on factors, such as the severity of TR, right ventricular dysfunction, and pulmonary arterial hypertension. Overall, interventional TR treatment is a promising advancement in treatment from which many patients can benefit in the future.

Abstract
BACKGROUND Improvement in concomitant tricuspid regurgitation (TR) after mitral valve transcatheter edge-to-edge repair (M-TEER) for mitral regurgitation (MR) occurs frequently; however factors determining the post-procedural course of TR are not well understood. We investigated the parameters associated with TR improvement after M-TEER. METHODS AND RESULTS A total of 300 patients were consecutively included in this retrospective analysis. MR and TR severity as well as heart chamber metrics were assessed before the procedure and at follow-up. Device success was achieved in 97.3% of patients. TR decreased in 30.2% of patients. Patients with improved TR were more often female, had more severe TR at baseline, and their right heart dimensions at baseline trended to be smaller. Female sex (odds ratio (OR) 2.997), baseline MR-Grade (OR 3.181) and baseline TR-Grade (OR 2.653) independently predicted TR reduction. More pronounced right heart reverse remodeling was observed in patients with improved TR. TR regression independently predicted lower mortality (hazard ratio (HR) 0.333, 95% confidence interval 0.112-0.996, p = 0.049). CONCLUSIONS A reduction in concomitant TR severity after M-TEER occurred mainly in females and in patients with high-grade TR and MR at baseline. TR regression is associated with better survival after M-TEER.

Abstract
AIMS To evaluate the impact of tricuspid regurgitation (TR) on echocardiographic and functional outcome after mitral valve transcatheter edge-to-edge-repair (M-TEER). METHODS AND RESULTS A total of 740 patients underwent M-TEER at our center from 2010 to 2021. Patients were analyzed according to severity of concomitant TR at the time of M-TEER procedure: low-grade TR (grade ≤I [trace-mild], 279 patients [37.7%]), moderate TR (grade II, 170 patients [23.0%]) and high-grade TR (grade III-V [severe-torrential], 291 patients [39.3%]). Patients with moderate to high-grade TR had higher morbidity. Procedural success of M-TEER was achieved similarly in all groups (98.2% vs. 97.6% vs. 95.9%, p = 0.22). TR severity decreased rapidly and consistently after M-TEER to only 48.0% of high-grade TR patients after 3 months (p < 0.001) and to 46.8% after 12 months (p = 0.99). High-grade TR patients had significantly higher mortality (21.5% vs. 18.2% vs. 11.1%, p = 0.003) up to 12 months after M-TEER. However, high-grade TR did not independently predict mortality (HR 1.302, 95% CI 0.937-1.810; p = 0.116). Echocardiographic and functional outcome was similar in both secondary and primary MR patients. CONCLUSIONS High-grade concomitant TR did not independently predict adverse outcome following M-TEER. A wait-and-observe approach for these patients is reasonable.

Abstract
Background Severe tricuspid regurgitation (TR) may persist after a mitral transcatheter edge-to-edge repair (M-TEER) and is associated with worsened clinical outcomes and survival. It is unclear which patients with concomitant mitral regurgitation (MR) and TR will have TR reduction after M-TEER. The aim of this study was to identify the predictors of residual TR after transcatheter edge-to-edge repair (TEER). Methods Data were collected from the Northwell TEER registry, a prospectively maintained mandatory database including 4 high-volume transcatheter aortic valve replacement/TEER centers. Transthoracic echocardiograms, both pre-TEER and post-TEER, were evaluated. Univariate and multivariate logistic regression analyses were performed to identify predictors of severe TR after M-TEER. Significant TR reduction was defined as a reduction in TR grade by at least 1+ with moderate (2+) or less TR at 1 month. Results Of the 479 patients who underwent M-TEER, 107 patients with concomitant severe MR/TR were included. Successful MR reduction occurred in 89 patients (84%) and a significant TR reduction in 45 (42%). On the univariate analysis, the only predictors of severe residual TR were right atrial area and unsuccessful M-TEER. On the multivariate logistic regression model, the only predictor variable for patients with a reduction in TR was MR reduction of ≥3+ with M-TEER. Conclusions In patients with concomitant severe MR and TR, TR reduction after isolated M-TEER occurs in only ∼40% of patients. MR grade reduction ≥3+ was the only independent predictor for TR reduction. Other clinical and echocardiographic variables (including pulmonary hypertension, right ventricular function, tricuspid annular dilation, atrial fibrillation, and presence of a cardiac implantable electrical device) were not associated with residual TR. Inability to predict TR reduction after M-TEER highlights the importance of establishing transcatheter tricuspid valve therapies and should factor in heart-team discussions.

Abstract
BACKGROUND The fourth-generation MitraClip G4 System builds on the previous NTR/XTR system with additional wider clip sizes (NTW and XTW), an independent grasping feature, and an improved clip deployment sequence. OBJECTIVES The primary objective of this study was to assess the safety and performance of the MitraClip G4 System within a contemporary real-world setting. METHODS EXPAND G4 is a prospective, multicenter, international, single-arm, postapproval study that enrolled patients with primary (degenerative) mitral regurgitation (MR) and secondary (functional) MR at 60 centers. Follow-up of the full cohort has been conducted through 30 days. Echocardiograms were analyzed by an echocardiography core laboratory. Study outcomes included MR severity, functional capacity measured by NYHA functional class, quality of life measured using the Kansas City Cardiomyopathy Questionnaire, major adverse event rates, and all-cause mortality. RESULTS In EXPAND G4, 1,141 subjects with primary MR and secondary MR were treated from March 2021 to February 2022. Implantation and acute procedural success rates were 98.0% and 96.2%, respectively, with a mean of 1.4 ± 0.6 clips implanted per subject. MR was significantly reduced at 30 days compared with baseline (98% achieved MR ≤ 2+, and 91% achieved MR ≤ 1+; P < 0.0001). Functional capacity and quality of life were substantially improved, with 83% of patients achieving NYHA functional class I or II. Likewise, an 18-point improvement was observed in Kansas City Cardiomyopathy Questionnaire summary scores compared with baseline. The composite major adverse event rate was 2.7%, and the all-cause death rate was 1.3% at 30 days. CONCLUSIONS This study demonstrates for the first time the effectiveness and safety of MitraClip G4 System at 30 days in a cohort of >1,000 patients with MR in a contemporary, real-world setting.

Abstract
Background There are limited data on repeat mitral transcatheter edge-to-edge repair for recurrent significant mitral regurgitation (MR). Methods and Results We conducted a single-center, retrospective analysis of consecutive patients referred to a second mitral transcatheter edge-to-edge repair after a technically successful first procedure. Clinical, laboratory, and echocardiographic measures were assessed up to 1 year after the intervention. The composite of all-cause death or heart failure (HF) hospitalizations constituted the primary outcome. A total of 52 patients (median age, 81 [interquartile range, 76-87] years, 29 [55.8%] men, 26 [50.0%] with functional MR) met the inclusion criteria. MR recurrences were mostly related to progression of the underlying cardiac pathology. All procedures were technically successful. At 1 year, most patients with available records (n=24; 96.0%) experienced improvement in MR severity or New York Heart Association functional class that was statistically significant but numerically modest. Fourteen (26.9%) patients died or were hospitalized due to HF. These were higher-risk cases with predominantly functional MR who mostly underwent an urgent procedure and exhibited more severe HF indices before the intervention, as well as an attenuated 1-month clinical and echocardiographic response. Overall, 1-year course was comparable to that experienced by patients who underwent only a first transcatheter edge-to-edge repair at our institution (n=902). Tricuspid regurgitation of greater than moderate grade was the only baseline parameter to independently predict the primary outcome. Conclusions Repeat mitral transcatheter edge-to-edge repair is feasible, safe, and clinically effective, especially in non-functional MR patients without concomitant significant tricuspid regurgitation.

Abstract
Multiple valve heart disease refers to the simultaneous presence of several valvular anomalies, while mixed valvular heart disease refers to the combination of stenotic lesions or regurgitation affecting the same valve. The pathophysiology of multiple and mixed valvular heart disease depends on the combination of affected valves and the severity of the individual valvular defects. Imaging is essential for diagnosis and assessment of disease severity. The treatment of combined valvular defects currently represents a challenge for both cardiac surgeons and interventional cardiologists since only few data in the literature address the clinical and therapeutic decision-making process related to these complex lesions. These are heterogeneous conditions, which differ from each other in the combination of the valves involved, in the pathogenesis with which they develop, in the severity of the individual lesions, in the associated surgical risk, in the possibility of being repaired, and in the undergoing transcatheter treatments. In addition to the severity of the individual valve defects, the choice of treatment also depends on the ventricular function and the general condition of the patient. This work aims to provide a review of the state of the art regarding the possible management strategies of the most common multiple valve diseases in clinical practice.

Abstract
Secondary (functional) tricuspid regurgitation (sTR) is common in patients with mitral regurgitation (MR). Because combined valvular heart disease affects long-term survival, in comparison with isolated MR or tricuspid regurgitation, it is essential to offer patients adequate treatment. Despite considerable experience, no conclusive data are yet available on the prognostic impact of concomitant tricuspid valve surgery at the time of mitral valve surgery. Emerging transcatheter treatments offer the opportunity to treat both conditions (MR and sTR) simultaneously or in a stepwise fashion. This review provides a clinical overview on available data regarding the rationale for treatment of sTR in patients with relevant MR undergoing mitral transcatheter edge-to-edge repair, focusing on clinical and anatomical selection criteria.

Abstract
Mitral regurgitation (MR) is the most prevalent valvular heart disease and, when left untreated, results in reduced quality of life, heart failure, and increased mortality. Mitral valve transcatheter edge-to-edge repair (M-TEER) has matured considerably as a non-surgical treatment option since its commercial introduction in Europe in 2008. As a result of major device and interventional improvements, as well as the accumulation of experience by the interventional cardiologists, M-TEER has emerged as an important therapeutic strategy for patients with severe and symptomatic MR in the current European and American guidelines. Herein, we provide a comprehensive up-do-date overview of M-TEER. We define preprocedural patient evaluation and highlight key aspects for decision-making. We describe the currently available M-TEER systems and summarise the evidence for M-TEER in both primary mitral regurgitation (PMR) and secondary mitral regurgitation (SMR). In addition, we provide recommendations for device selection, intraprocedural imaging and guiding, M-TEER optimisation and management of recurrent MR. Finally, we provide information on major unsolved questions and "grey areas" in M-TEER.

Abstract
AIM To evaluate short-term changes in tricuspid regurgitation (TR) after transcatheter edge-to-edge mitral valve repair (M-TEER) in secondary mitral regurgitation (SMR), their predictors and impact on mortality. METHODS AND RESULTS This is a retrospective analysis of SMR patients undergoing successful M-TEER (post-procedural mitral regurgitation ≤2+) at 13 European centres. Among 503 patients evaluated 79 (interquartile range [IQR] 40-152) days after M-TEER, 173 (35%) showed ≥1 degree of TR improvement, 97 (19%) had worsening of TR, and 233 (46%) remained unchanged. Smaller baseline left atrial diameter and residual mitral regurgitation 0/1+ were independent predictors of TR ≤2+ after M-TEER. There was a significant association between TR changes and New York Heart Association class and pulmonary artery systolic pressure decrease at echocardiographic re-assessment. At a median follow-up of 590 (IQR 209-1103) days from short-term echocardiographic re-assessment, all-cause mortality was lower in patients with improved compared to those with unchanged/worsened TR (29.6% vs. 42.3% at 3 years; log-rank p = 0.034). Baseline TR severity was not associated with mortality, whereas TR 0/1+ and 2+ at short-term follow-up was associated with lower all-cause mortality compared to TR 3/4+ (30.6% and 35.6% vs. 55.6% at 3 years; p < 0.001). A TR ≤2+ after M-TEER was independently associated with a 42% decreased risk of mortality (p = 0.011). CONCLUSION More than one third of patients with SMR undergoing successful M-TEER experienced an improvement in TR. Pre-procedural TR was not associated with outcome, but a TR ≤2+ at short-term follow-up was independently associated with long-term mortality. Optimal M-TEER result and a small left atrium were associated with a higher likelihood of TR ≤2+ after M-TEER.

Abstract
Since transcatheter edge-to-edge repair (TEER) has become a valuable therapy in the treatment of both, mitral (MR) and tricuspid regurgitation (TR), the question of optimized patient selection has gained growing importance. After years of attributing rather little attention to the right ventricle (RV) and its function in the setting of valvular heart failure, this neglect has recently changed. The present review sought to summarize anatomy and function of the RV in a clinical context and aimed at presenting the current knowledge on how the RV influences outcomes after TEER for atrioventricular regurgitation. The anatomy of the RV is determined by its unique shape, which necessitates to use three-dimensional imaging methods for detailed and comprehensive characterization. Complex parameters such as RV to pulmonary artery coupling (RVPAc) have been developed to combine information of RV function and afterload which is primary determined by the pulmonary vasculature and LV filling pressure. Beyond that, TR, which is closely related to RV function also plays an important role in the setting of TEER. While mitral valve transcatheter edge-to-edge repair (M-TEER) leads to reduction of concomitant TR in some patients, the prognostic value of TR in the setting of M-TEER remains unclear. Overall, this review summarizes the current state of knowledge of the outstanding role of RV function and associated TR in the setting of TEER and outlines the unsolved questions associated with right-sided heart failure.

Abstract
PURPOSE OF REVIEW In this review, we have focused on the currently available transcatheter tricuspid valve therapies, device selection, as well as role and management of tricuspid regurgitation (TR) in the setting of other transcatheter valvular procedures. RECENT FINDINGS In this review, we have enlisted the recently finished as well as ongoing trials in the percutaneous tricuspid valve therapies. TR is highly prevalent yet remains underrecognized and is often untreated. TR has traditionally been managed conservatively with medical therapies including diuretics for volume management, whereas surgical therapies are reserved for those undergoing left-sided valvular surgery. Although the transcatheter devices for tricuspid repair and replacement are in clinical trials, the experience to date for their effectiveness and safety has been reassuring.

Abstract
Heart failure through the spectrum of reduced (HFrEF), mid-range (or mildly reduced or HFmEF), and preserved ejection fraction (HFpEF), continues to plague patients' quality of life through recurrent admissions and high mortality rates. Despite tremendous innovation in medical therapy, patients continue to experience refractory congestive symptoms due to adverse left ventricular remodeling, significant functional mitral regurgitation (FMR), and right-sided failure symptoms due to significant functional tricuspid regurgitation (FTR). As most of these patients are surgically challenging for open cardiac surgery, the past decade has seen the development and evolution of different percutaneous structural interventions targeted at improving FMR and FTR. There is renewed interest in the sphere of left ventricular restorative devices to effect reverse remodeling and thereby improve effective stroke volume and patient outcomes. For patients suffering from HFpEF, there is still a paucity of disease-modifying effective medical therapies, and these patients continue to have recurrent heart failure exacerbations due to impaired left ventricular relaxation and high filling pressures. Structural therapies involving the implantation of inter-atrial shunt devices to decrease left atrial pressure and the development of implantable devices in the pulmonary artery for real-time hemodynamic monitoring would help redefine treatment and outcomes for patients with HFpEF. Lastly, there is pre-clinical data supportive of soft robotic cardiac sleeves that serve to improve cardiac function, can assist contraction as well as relaxation of the heart, and have the potential to be customized for each patient. In this review, we focus on the role of structural interventions in heart failure as it stands in current clinical practice, evaluate the evidence amassed so far, and review promising structural therapies that may transform the future of heart failure management.

Abstract
OBJECTIVES Investigate the impact of concomitant tricuspid regurgitation (TR) on clinical outcomes during long-term follow-up in patients undergoing percutaneous treatment of mitral regurgitation (MR) with the MitraClip system. BACKGROUND Patients undergoing mitral repair using the MitraClip frequently present with concomitant TR. It is uncertain how the presence of TR impacts the long-term outcomes of such patients. METHODS We analyzed consecutive patients with MitraClip implantation from the prospective MitraSwiss registry. Endpoints were all-cause mortality, hospitalization for heart failure, and the composite endpoint of the two. RESULTS We enrolled 177 patients (mean age 76 ± 9 years, 37% female). Acute procedural success was achieved in 149 (84%). Concomitant moderate or severe TR was present in 31% at baseline and 32% before discharge. After a median follow-up of 1103 days (IQR: 555-1766 days), 70 (40%) of patients had died, and 34 (19%) were hospitalized for heart failure. In multivariable analysis, TR at baseline was associated with an increase in all-cause mortality (HR: 2.34, 95% CI: 1.36-4.03, p < 0.01), hospitalization for heart failure (HR: 3.19, 95% CI: 1.37-7.41, p = 0.01), and the composite endpoint (HR: 2.00, 95% CI: 1.19-3.36, p = 0.01). CONCLUSION Despite treatment of MR, TR did not improve in most patients. The presence of relevant TR at baseline was associated with reduced survival and higher rates of hospitalization for heart failure. More research is needed to understand the causal role of TR in such patients and to investigate if simultaneous treatment of concomitant TR may improve prognosis in patients undergoing percutaneous treatment of MR.

Early symptomatic benefit indicates long-term prognosis after transcatheter mitral valve edge-to-edge repair in functional and degenerative etiology. Int J Cardiol 2021; 344:141-146. [PMID: 34563598 DOI: 10.1016/j.ijcard.2021.09.038] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Revised: 09/04/2021] [Accepted: 09/17/2021] [Indexed: 01/29/2023]
Abstract
BACKGROUND Mitral regurgitation (MR) is common in patients with heart failure and constitutes an independent risk factor for adverse prognosis besides NYHA-class. The predictive value of dyspnea reduction after transcatheter mitral valve repair (TMVr) on outcome has not been investigated up to now. METHODS AND RESULTS We enrolled 627 consecutive patients (47.0% female, 57.4% functional MR; median follow-up 486 days[IQR 157/961]; survival status available in 96.8%; symptoms assessed in n = 556 at baseline / n = 406 at 1 month) treated with isolated percutaneous mitral valve edge-to-edge repair in our center from 06/2010-03/2018 (exclusion of combined forms of TMVr) in a monocentric retrospective analysis. Survival was 97.6% at discharge, 73.9% after 1, 54.5% after 3, 37.6% after 5 and 21.7% after 7-years. Before TMVr, NYHA-classes III/IV were found in 89.0%. Of these, 74.7% reported symptomatic relief (reduction in NYHA-class) one month after procedure (NYHA class recorded in 406 patients at 30 days). NYHA-classes III/IV were documented in 37.2% (p < 0.001) at 30 days and in 36.6% (p < 0.001) at 1 year without significant changes between the follow-ups. Dyspnea reduction was accompanied by significantly improved long-term survival (1 year, 89.1 vs 71.2%, p = 0.001, 2 years: 75.5 vs 58.7%, p = 0.039) and was identified as an independent predictor for lower mortality (1-year HR for increased mortality by missing symptomatic improvement 2.94 [95%CI 1.53-5.65], p = 0.001; long-term HR 1.95 [95%CI 1.29-2.94], p = 0.001) independently in both etiologies of MR. CONCLUSION TMVr by edge-to-edge therapy enables early and sustainable symptomatic improvement in nearly 75% of the symptomatic patients. The simple assessment of postinterventional changes in NYHA-class might serve as an independent predictor for mid- and long-term prognosis in both FMR and DMR.

Impact of gender on in-hospital mortality and 90-day readmissions in patients undergoing transcatheter edge-to-edge mitral valve repair: Analysis from the National Readmission Database. Catheter Cardiovasc Interv 2021; 98:E954-E962. [PMID: 34343407 DOI: 10.1002/ccd.29887] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 07/07/2021] [Accepted: 07/16/2021] [Indexed: 11/11/2022]
Abstract
BACKGROUND Patients undergoing transcatheter edge-to-edge mitral valve repair (TEER) carry a high risk of rehospitalization due to disease, procedure, patient, hospital, and system related factors. AIMS We aimed to explore the impact of gender on in-hospital mortality and 90-day readmissions in patients undergoing TEER. METHODS We utilized the National Readmission Database from 2012 to 2018 to identify individuals who underwent TEER for mitral regurgitation. Gender-based differences in in-hospital mortality and 90-day readmissions were explored using multivariable logistic regression models. RESULTS Between 2012 and 2018, an estimated 21,415 TEER procedural hospitalizations were identified, of which 9893 (46.2%) were in women and 11,522 (53.8%) were in men. Compared with men, women were older, from a lower socioeconomic status but had a lower co-morbidity burden. In-hospital mortality rate during the index hospitalization was similar in women and men (2.1% vs. 2.1%, p = 0.908). Ninety-day all-cause and heart failure readmission rates were significantly higher in women compared to men (30.2% vs. 25.4%; p < 0.001 and 28.1% vs. 23.9%; p = 0.020 respectively). In a multivariable analysis, women had 36% greater odds of 90-day readmission compared to men (adjusted odds ratio [aOR] 1.36, 95% CI: 1.22-1.52; p < 0.001). Trend analysis revealed no significant improvement in rates of 90-day readmission during the observation period for men or women (p = 0.245, p = 0.429, respectively). CONCLUSIONS Following TEER, there has been no significant improvement in 90-day readmission rates between 2012 and 2018. Female gender is associated with higher 90-day all-cause and heart failure readmission rates.

JACC Cardiovasc Interv 2021; 14:1538-1548. [PMID: 34020928 DOI: 10.1016/j.jcin.2021.04.001] [Citation(s) in RCA: 36] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 04/01/2021] [Accepted: 04/06/2021] [Indexed: 02/07/2023]
Abstract
OBJECTIVES This study reports 2-year outcomes from the multicenter, prospective, single-arm CLASP study with functional mitral regurgitation (FMR) and degenerative MR (DMR) analysis. BACKGROUND Transcatheter repair is a favorable option to treat MR. Long-term prognostic impact of the PASCAL transcatheter valve repair system in patients with clinically significant MR remains to be established. METHODS Patients had clinically significant MR ≥3+ as evaluated by the echocardiographic core laboratory and were deemed candidates for transcatheter repair by the heart team. Assessments were performed by clinical events committee to 1 year (site-reported thereafter) and core laboratory to 2 years. RESULTS A total of 124 patients (69% FMR, 31% DMR) were enrolled with a mean age of 75 years, 56% were male, 60% were New York Heart Association functional class III to IVa, and 100% had MR ≥3+. At 2 years, Kaplan-Meier estimates showed 80% survival (72% FMR, 94% DMR) and 84% freedom from heart failure (HF) hospitalization (78% FMR, 97% DMR), with 85% reduction in annualized HF hospitalization rate (81% FMR, 98% DMR). MR ≤1+ was achieved in 78% of patients (84% FMR, 71% DMR) and MR ≤2+ was achieved in 97% (95% FMR, 100% DMR) (all p < 0.001). Left ventricular end-diastolic volume decreased by 33 ml (p < 0.001); 93% of patients were in New York Heart Association functional class I to II (p < 0.001). CONCLUSIONS The PASCAL repair system demonstrated sustained favorable outcomes at 2 years in FMR and DMR patients. Results showed high survival and freedom from HF rehospitalization rates with a significantly reduced annualized HF hospitalization rate. Durable MR reduction was achieved with evidence of left ventricular reverse remodeling and significant improvement in functional status. The CLASP IID/IIF randomized pivotal trial is ongoing.
