Abstract Background/Introduction Transcatheter mitral valve repair (TMVR) in patients with heart failure (HF) and severe mitral regurgitation (MR) entails better clinical and symptomatic status. While emerging evidence indicate that HF duration is linked to adverse outcomes in patients with HF, it is not known whether the HF duration before TMVR has an effect on adverse outcomes. Purpose We aimed to assess the association between duration of HF before TMVR and clinical prognosis after the procedure. Methods We retrospectively enrolled a total of 345 patients who underwent TMVR procedure with MitraClip or Cardioband system for the treatment of symptomatic MR after guideline recommended therapy. The patients were divided into 2 groups according to the duration of HF (>18 months:, n=161, ≤18 months: shorter HF group, n=184). Cox proportional hazards analysis was performed to assess the association between duration and two-year composite endpoint (all-cause mortality, unexpected hospitalization due to HF, and repeat mitral valve therapy). Results Patients with longer duration of HF were more likely to be male, had greater incidence of coronary artery disease (77.0% vs. 51.6%, p<0.001), had received more frequently implantable cardioverter defibrillator or cardiac resynchronization therapy (41.0% vs. 10.3%, p<0.001), and had more decreased left ventricular ejection fraction (41.1±14.5% vs. 49.3±16.0%, p<0.001) compared to patients with shorter duration of HF. Two-year event-free survival rate was significantly lower in patients with longer duration of HF (66.3% vs. 83.8%, Log-rank p=0.01) compared to whose with shorter duration of HF. Similar trends were observed for all-cause mortality (84.8% vs. 95.9%, p=0.06) and repeat mitral valve therapy (93.4% vs. 100%, p=0.02). In the Cox proportional hazard analysis, longer duration of HF was independently associated with increased risk of adverse outcomes (Hazard ratio, 2.26; 95% confidence interval, 1.11–4.62; p=0.02) compared with shorter duration of HF. Conclusion Patients with the longer duration of HF before TMVR is independently associated with increased risk of adverse outcomes after the procedure. It is, however, accompanied by higher prevalence of cardiac co-morbidities in these patients. Our findings suggest that a longer duration of HF is a risk indicator and should be considered into in future clinical trials of TMVR.

Abstract Background Little is known about early right ventricular (RV) response to transcatheter mitral valve repair (TMVR) and its association with clinical outcomes. We assessed the early effect of TMVR on the RV function (RVF) and sought to investigated the prognostic impact of post-procedural RV dysfunction. Methods From January 2011 through April 2019, consecutive patients who underwent MitraClip for severe mitral regurgitation were analyzed. We excluded patients in which the evaluation of RVF were un available. RV dysfunction was defined by an RV fractional area change (RVFAC) &lt;35% or tricuspid annular planar systolic excursion (TAPSE) &lt;16 mm. A Cox proportional regression analysis was conducted to investigate the association of post-procedural RV dysfunction with adverse outcomes (all-cause mortality and rehospitalization due to heart failure [HF]). Results A total of 403 patients were analyzed.Overall, the mean age was 78 years old and 59% of patients were male. The median left-ventricular ejection fraction (LVEF) was 46.1% [IQR 33.1–59.4], RVFAC was 41.9% [IQR 32.9–49.5], and TAPSE was 17 mm [IQR 14–22]. While 68 patients showed an acute improvement of RVF (35% of patients with baseline RV dysfunction), 51 patients (25% of patients with baseline normal RVF) showed an acute worsening of RVF. In patients with baseline normal RVF, atrial fibrillation (OR 4.57, 95% CI 1.56–13.40, p=0.006, HF duration &gt;18 months (OR 2.95, 95% CI 1.32–6.60, p=0.009), LVEF &lt;50% (OR 3.09, 95% CI 1.32–7.25, p=0.009), and tricuspid regurgitation≥3+ (OR 5.62, 2.28–13.90, p&lt;0.001)were associated with an increased risk of acute worsening of RVF. By contrast, in patients with baseline RV dysfunction, HF duration &gt;18 months (OR 0.43, 95% CI 0.22–0.85, p=0.01) and larger RV volume (OR 0.98, 95% CI 0.97–0.99, p&lt;0.001) were associated with less probability of acute RVF improvement. The event-free survival was significantly different according to the subgroup of variation of RVF (p=0.003). Furthermore, post-procedural RV dysfunction was associated with an increased risk of outcomes (adjusted-HR 2.38, 95% CI 1.28–4.43, p=0.006). Conclusion Both acute improvement and worsening of RVF can be observed after TMVR. Post-procedural RV dysfunction is an independent predictor of adverse outcomes.

Abstract Background Left atrial (LA) function predicts clinical outcome in a variety of cardiovascular diseases. However, limited data is available in the setting of mitral regurgitation (MR). Purpose The aim of the present study was to assess potential changes in LA ejection fraction (LA-EF) and its prognostic value in patients following transcatheter mitral valve repair using the mitraclip. Methods A total of 88 consecutive patients undergoing mitraclip implantation with complete echocardiography at baseline and follow-up between 3 and 6 months post-procedure were enrolled. Results LA-EF improved in 58% of the population. Change in LA-EF was associated with residual MR, residual transmitral gradient and left ventricular ejection fraction (LV-EF) changes. Compared to their counterparts, patients with residual MR ≥ grade 2 (−6% [−9 to 1%] vs. 4% [−5 to 15%]; p=0.05) and with residual transmitral gradient ≥5 mmHg (−2% [−9 to 9%] vs. 5% [−4 to 16%]; p=0.03) showed a decline in LA-EF, respectively. Furthermore, LA-EF significantly correlated with changes in LV-EF (r=0.40; p=0.001). With regards to clinical outcome, heart failure symptoms as assessed by NYHA class were more severe in patients with worsened LA-EF at follow-up. Finally, LA-EF change was identified as independent predictor of all-cause mortality (HR 0.94 [0.90–0.98]; p=0.008). Kaplan-Meier estimates for survival Conclusion The present analysis showed changes in LA function in patients undergoing mitraclip implantation to be associated with important measures including residual MR, elevated transmitral gradient and LV function. Importantly, LA function alterations represent a strong predictor for all-cause mortality.

Aims To evaluate whether CMR-derived RV assessment can facilitate risk stratification among patients undergoing transcatheter mitral valve repair (TMVR). Background In patients undergoing TMVR, only limited data exist regarding the role of RV function. Previous studies assessed the impact of pre-procedural RV dysfunction stating that RV failure may be associated with increased cardiovascular mortality after the procedure. Methods Sixty-one patients underwent CMR, echocardiography and right heart catheterization prior TMVR. All-cause mortality and heart failure hospitalizations were assessed during 2-year follow-up. Results According to RV ejection fraction (RVEF) <46%, 23 patients (38%) had pre-existing RV dysfunction. By measures of RV end-diastolic volume index (RVEDVi), 16 patients (26%) revealed RV dilatation. Nine patients (15%) revealed both. RV dysfunction was associated with increased right and left ventricular volumes as well as reduced left ventricular (LV) ejection fraction (all p<0.05). During follow-up, 15 patients (25%) died and additional 14 patients (23%) were admitted to hospital due to heart failure symptoms. RV dysfunction predicted all-cause mortality even after adjustment for LV function. Similarly, RVEDVi was a predictor of all-cause mortality even after adjustment for LVEDVi. Kaplan-Meier survival analysis unraveled that, among patients presenting with CMR indicative of both, RV dysfunction and dilatation, the majority (78%) experienced an adverse event during follow-up (p<0.001). Conclusion In patients undergoing TMVR, pre-existing RV dysfunction and RV dilatation are associated with reduced survival, in progressive additive fashion. The assessment of RV volumes and function by CMR may aid in risk stratification prior TMVR in these high-risk patients.

Abstract Background Moderate-to-severe or severe functional mitral regurgitation (FMR) is associated with higher rates of hospitalizations and with increased mortality in heart failure (HF). Transcatheter mitral valve repair by MitraClip® implantation (TMVrMC) may effectively reduce severe MR, and is associated with symptomatic improvement. However, the long-term clinical effects of this procedure are not well defined. Aims We analyzed outcomes for rehospitalization and survival in HF patients with moderate-to-severe or severe FMR treated by either medical treatment (MT) only versus TMVrMC+MT by meta-analysis. Methods and results By systematic search of bibliographic databases, we evaluated publications comparing HF patients with FMR treated by MT only versus treatment by MT combined with TMVrMC. Studies with a minimum of 25 enrolled patients and a follow/up period of at least 12 months were deemed eligible for this meta-analysis. We identified n=7 studies enrolling 2,884 HFrEF patients, divided into two study arms: TMVrMC+MT (n=1,618), versus FMR patients receiving MT only (n=1,266). At 12 months, there was a significant reduction in all-cause mortality favoring TMVrMC+MT (OR: 0.65; CI 95% 0.53–0.79), compared with the MT only patients. At 24 months, a significant reduction of all-cause mortality in the TMVrMC+MT patient group (OR: 0.54; CI: 95%: 0.43–0.67; p&lt;0.001) was calculated. TMVrMC+MT was associated with significantly lower rates of unplanned re-admissions for heart failure compared with MT only at 12 months (OR: 0.69; 95%; CI 0.53–0.89; p&lt;0.001) and at 24 months (OR: 0.53; 95% CI: 0.39–0.71; p&lt;0.001). In one publication, a survival benefit of TMVrMC+MT over MT alone was shown at 5 years post intervention (HR: 0.75; 95% CI: 0.69–0.94; p=0.012) after weighting for propensity score and controlling for age. Conclusions This meta-analysis on n=2,884 patients with moderate-to-severe or severe FMR reveals that TMVrMC+MT, as compared with MT alone, is associated with a significant reduction of rehospitalizations and improvement of survival up to 24 months after MitraClip implantation. However, the discordant results of 2 randomized controlled trials (MITRA-FR and COAPT) warrant further clarification, i.e. of the eligible FMR patient profiles who might benefit from TMVrMC+MT in terms of improvement of prognosis. These data imply additional evidence for TMVrMC in eligible HF patients with relevant FMR, which might be important for an update of the corresponding guidelines.

Background Optimizing risk stratification in patients undergoing transcatheter mitral valve repair is an ongoing challenge. The Mitral Regurgitation International Database (MIDA) score represents a user‐friendly mortality risk stratification tool that is validated on a large‐scale registry of patients with degenerative mitral regurgitation (MR). We here assessed the potential benefit of the MIDA risk score for patients with functional or degenerative MR undergoing transcatheter mitral valve repair. Methods and Results In total, 680 patients undergoing MitraClip implantation were stratified according to MIDA score tertiles into a low (0–7), intermediate (8–9), and a high (10–12) MIDA score group. MR was assessed in follow‐up echocardiograms in 416 patients at 323±169 days after transcatheter mitral valve repair. During 2‐year follow‐up, 8.2% (15/182) of patients with low, 21.3% (64/300) with intermediate, and 26.3% (52/198) with high MIDA score died (log‐rank test P <0.001). Hazard of all‐cause mortality increased by 13% (95% CI, 3%–25%) with every additional point of the MIDA score. Subanalysis of 431 patients with functional MR showed similar results. Furthermore, rates of a combined end point of mortality and hospitalization for heart failure were higher with increasing MIDA score (30% [54/182], 38% [113/300] and 48% [94/198], respectively, log‐rank test P =0.001). Frequency of residual MR ≥II at follow‐up increased with increasing MIDA score group (33%, 44%, and 59%, respectively, P <0.001). Conclusions The MIDA mortality risk score maintains its predictive utility in patients undergoing transcatheter mitral valve repair, regardless of MR cause. Moreover, it was predictive of worse event‐free survival regarding a combined end point of mortality and hospitalization for heart failure, and was associated with postprocedural residual MR ≥II and MR recurrence.

Abstract Background Hepatorenal dysfunction is a strong prognostic predictor in patients with heart failure. However, the prognostic impact of the hepatorenal dysfunction in patients undergoing transcatheter mitral valve repair (TMVR) has not been well studied. Methods In consecutive patients who underwent edge-to-edge TMVR at three German centers, the model for end-stage liver disease excluding international normalized ratio (MELD-XI) score was calculated as 5.11 × ln [serum total bilirubin (mg/dl)] + 11.76 × ln [serum creatinine (mg/dl)] + 9.44. Patients were stratified into high (> 11) or low (≤ 11) MELD-XI score of which an incidence of the composite outcome, consisting of all-cause mortality and heart failure hospitalization, within 2 years after TMVR was assessed. Results Of the 881 patients, the mean MELD-XI score was 11.0 ± 5.9, and 415 patients (47.1%) had high MELD-XI score. The MELD-XI score was correlated with male, effective regurgitant orifice area, and tricuspid regurgitation severity and inversely related to left ventricular ejection fraction. Patients with high MELD-XI score had a higher incidence of the composite outcome than those with low MELD-XI score (47.7% vs. 29.8%; p < 0.0001), and in multivariable analysis, the high MELD-XI score was an independent predictor of the composite outcome [adjusted hazard ratio (HR) 1.34; 95% confidence interval (CI) 1.02–1.77; p = 0.04). Additionally, the MELD-XI score as a continuous variable was also an independent predictor (adjusted HR 1.02; 95% CI 1.00–1.05; p = 0.048). Conclusions The MELD-XI score was associated with clinical outcomes within 2 years after TMVR and can be a useful risk-stratification tool in patients undergoing TMVR.

<b><i>Background:</i></b> Severe secondary mitral regurgitation (MR) is associated with poor prognosis in heart failure patients with left ventricular systolic dysfunction. Few observational and randomized controlled studies demonstrated the efficacy of transcatheter mitral valve repair in heart failure patients with significant MR. A meta-analysis of published studies was performed to evaluate the role of transcatheter mitral valve repair using the MitraClip device in heart failure patients with significant secondary MR. <b><i>Methods:</i></b> A literature search was performed using PubMed, Cochran CENTRAL, and Embase databases using the search terms “percutaneous mitral valve repair” or “transcatheter mitral valve repair” and “heart failure.” Studies that compared medical therapy plus transcatheter mitral valve repair using MitraClip to medical therapy alone in heart failure patients with significant secondary MR were included for pooled analysis. A random-effects model with the Mantel-Haenszel method was used to analyze the data. <b><i>Results:</i></b> Four studies, 2 randomized controlled and 2 nonrandomized studies met the criteria for analysis. Pooled analysis included a total of 1,421 patients, of which 746 patients underwent transcatheter mitral valve repair and 675 patients received medical therapy alone. When compared to medical therapy, transcatheter mitral valve repair significantly decreased all-cause mortality (OR 0.58, 95% CI 0.37–0.91; <i>p</i> = 0.02). A trend toward significant reduction in rehospitalizations (OR 0.35, 95% CI 0.12–1.00; <i>p</i> = 0.05) was also observed. Periprocedural complications ranged from 7.5 to 12.6%. <b><i>Conclusion:</i></b> Evidence from pooled analysis suggests that transcatheter mitral valve repair using MitraClip on top of medical therapy, in appropriately selected symptomatic heart failure patients with significant secondary MR, provides survival benefit and may decrease hospitalizations when compared with guideline-directed medical therapy alone.
