Abstract
Although MitraClip has been studied in numerous trials, its evidence in the long term is based on a few original studies. We used an original technique of evidence synthesis to review long-term comparative trials evaluating MitraClip. We searched the PubMed database to select long-term comparative trials of MitraClip. The endpoint was all-cause mortality (minimum follow-up, one year). Included trials were analyzed using the IPDfromKM (reconstruct Individual Patient Data from published Kaplan-Meier survival curves) method to reconstruct individual patient data from Kaplan-Meier curves. Standard survival statistics were used to interpret these long-term efficacy data. The survival benefit per patient was estimated from the restricted mean survival time (RMST). Six comparative studies of MitraClip were included; 973 patients were treated with MitraClip (six arms), 717 with medical therapy (five arms), and 80 with surgical repair or replacement (one arm). In our main analysis, the outcomes observed in patients treated with MitraClip were significantly better than those of medical therapy (hazard ratio for all-cause mortality, 0.5276; 95% confidence interval, 0.4412 to 0.6309; p < 0.001); the number of patients treated with surgery was too small to make reliable comparisons. Median survival was 30.4 months for medical therapy versus not reached for the other two groups. RMST was 43.931 and 33.756 months for MitraClip and controls, respectively, yielding a gain per patient of 10.17 months (95% confidence interval, 7.47 to 12.88). In our simplified cost-effectiveness evaluation, a gain of approximately 10 months per patient compared favorably with the device cost. Our analysis provided an original interpretation of the long-term evidence available on MitraClip.

Abstract
BACKGROUND Mitral regurgitation (MR) is the most common valvular disease in the United States and increases the risk of death and hospitalization. The economic burden of MR in the United States is not known. METHODS AND RESULTS We analyzed inpatient hospitalization data from the 1 221 173 Maryland residents who had any in-state admissions from October 1, 2015, to September 30, 2019. We assessed the total charges for patients without MR and for patients with MR who underwent medical management, transcatheter mitral valve repair or replacement, or surgical mitral valve repair or replacement. During the study period, 26 076 inpatients had a diagnosis of MR. Compared with patients without MR, these patients had more comorbidities and higher inpatient mortality. Patients with medically managed MR incurred average total charges of $23 575 per year; MR was associated with $10 559 more in charges per year and an incremental 3.1 more inpatient days per year as compared with patients without MR. Both surgical mitral valve repair or replacement and transcatheter mitral valve repair or replacement were associated with higher charges as compared with medical management during the year of intervention ($47 943 for surgical mitral valve repair or replacement and $63 108 for transcatheter mitral valve repair or replacement). Annual charges for both groups were significantly lower as compared with medical management in the second and third years postintervention. CONCLUSIONS MR is associated with higher mortality and inpatient charges. Patients who undergo surgical or transcatheter intervention incur lower charges compared with medically managed MR patients in the years after the procedure.

Abstract
This systematic review and meta-analysis aimed to investigate whether percutaneous mitral valve repair (PMVr) using MitraClip was more effective than surgery or medical therapy for long-term morbidity and mortality. We searched MEDLINE, EMBASE, and CENTRAL (Cochrane Library) databases to identify relevant studies that recruited adult patients with functional or secondary mitral valve regurgitation who underwent PMVr with MitraClip implantation using appropriate search terms and Boolean operators. The odds ratios (ORs) were pooled using the random-effects model. A total of 14 studies recruiting 2,593 patients were included. Within 12 months of follow-up, patients who underwent PMVr did not maintain mitral valve regurgitation grade 2+ (OR 0.22, 95% confidence interval [CI] 0.12 to 0.41, p <0.0001, I2 = 0.0%, p = 0.52) or symptom-free heart failure (OR 0.47, 95% CI 0.29 to 0.77, p = 0.0028, I2 = 0.0%, p = 0.66) compared with their surgical counterparts. Patients were more likely to be rehospitalized for heart failure (OR 2.79, 95% CI 1.54 to 5.05, p = 0.0007, I2 = 0.0%, p = 0.51). However, there was no difference between the groups in terms of all-cause or cardiovascular mortality. Whereas, in comparison with medical therapy, PMVr significantly reduced all-cause mortality at 12 and ≥24 months of follow-up (OR 0.41, 95% CI 0.24, 0.69, p = 0.0009, I2 = 32%, p = 0.23 and OR 0.55, 95% CI 0.40, 0.75, p = 0.0002, I2 = 0.0%, p = 0.45, respectively). In conclusion, there was no difference in all-cause death at 12 or 24 months of follow-up between PMVr and the surgical approach, but the durability of valvular repair was inferior with PMVr. In comparison with medical therapy, there was a significant reduction in mortality with PMVr.

Abstract
Heart failure (HF) is a major health concern, which accounts for 1-2% of all hospital admissions. Nevertheless, there remains a knowledge gap concerning which interventions contribute to effective prevention of HF (re)hospitalization. Therefore, this umbrella review aims to systematically review meta-analyses that examined the effectiveness of interventions in reducing HF-related (re)hospitalization in HFrEF patients. An electronic literature search was performed in PubMed, Web of Science, PsycInfo, Cochrane Reviews, CINAHL, and Medline to identify eligible studies published in the English language in the past 10 years. Primarily, to synthesize the meta-analyzed data, a best-evidence synthesis was used in which meta-analyses were classified based on level of validity. Secondarily, all unique RCTS were extracted from the meta-analyses and examined. A total of 44 meta-analyses were included which encompassed 186 unique RCTs. Strong or moderate evidence suggested that catheter ablation, cardiac resynchronization therapy, cardiac rehabilitation, telemonitoring, and RAAS inhibitors could reduce (re)hospitalization. Additionally, limited evidence suggested that multidisciplinary clinic or self-management promotion programs, beta-blockers, statins, and mitral valve therapy could reduce HF hospitalization. No, or conflicting evidence was found for the effects of cell therapy or anticoagulation. This umbrella review highlights different levels of evidence regarding the effectiveness of several interventions in reducing HF-related (re)hospitalization in HFrEF patients. It could guide future guideline development in optimizing care pathways for heart failure patients.

Abstract
Background Percutaneous mitral valve repair (PMVR) provides an available choice for patients suffering from secondary mitral regurgitation (SMR), especially those whose symptoms persist after optimal, conventional, heart-failure therapy. However, conflicting results from clinical trials have created a problem in identifying patients who will benefit the most from PMVR. Objective To pool mortality data and assess clinical predictors after PMVR among patients with SMR. To this end, subgroup and meta-regression analyses were additionally performed. Methods We searched PubMed, EMBASE, and Cochrane databases, and 13 studies were finally included for meta-analysis. Estimated mortality and 95% confidence intervals (CIs) were obtained using a random-effects proportional meta-analysis. We also carried out a meta-regression analysis to clarify the potential influence of important covariates on mortality. Results A total of 1,259 patients with SMR who had undergone PMVR were enrolled in our meta-analysis. The long-term estimated pooled mortality of PMVR was 19.3% (95% CI: 13.6–25.1). Meta-regression analysis showed that mortality was directly proportional to cardiac resynchronization therapy (CRT) (β = 0.009; 95% CI: 0.002–0.016; p = 0.009), an effective regurgitant orifice (ERO) (β = 0.009; 95% CI: 0.000–0.018; p = 0.047), and a mineralocorticoid receptor antagonist (MRA) use (β = −0.015; 95% CI: −0.023–−0.006; p < 0.001). Subgroup analysis indicated that patients with preexisting AF (β = −0.002; 95% CI: −0.005– −0.000; p = 0.018) were associated with decreased mortality if they received a mitral annuloplasty device. Among the edge-to-edge repair device group, a higher left ventricular (LV) ejection fraction, or lower LV end-systolic diameter, LV end-systolic volume, and LV end-diastolic volume were proportional to lower mortality. Conclusion and Relevance The pooled mortality of PMVR was 19.3% (95% CI: 13.6–25.1). Further meta-regression indicated that AF was associated with a better outcome in conjunction with the use of a mitral annuloplasty device, while better LV functioning predicted a better outcome after the implantation of an edge-to-edge repair device.

Abstract
OBJECTIVES Scientific literature debates on the economic affordability of transcatheter aortic valve implantation (TAVI) in order to give a useful support to decision makers aiming at establishing a reimbursement scheme for TAVI. For this reason, it is important to assess the quality and the generalizability of the existing economic evidences. METHODS The first step was to run a literature search according to a predefined population, intervention, comparator, and outcome on the cost and effectiveness of the TAVI procedure in comparison to medical therapy and traditional surgery. Second, a manual search was carried out on the Web sites of the main HTA agencies. Third, the checklist developed by Augustovski et al. was applied in order to assess the quality and the generalizability of the articles resulting from the selection process. RESULTS Overall, 106 articles were obtained. Of these, sixty-five articles were excluded since the title was not consistent with the objective. Further selection took place after abstract and full-text reading. In the end, thirty-one documents were included for the review. According to the checklist, none of the articles was considered generalizable and only one was considered transferable which compares the TAVI procedure with Medical Management in inoperable patients. CONCLUSIONS Despite the overall quality of the selected studies was considered good, there is still a lack of evidence on whether evidences generated in different contexts can be considered generalizable. Further research on resource consumption and preferences is needed in order to provide decision makers with more robust evidences.

Abstract
To assess the cost-effectiveness of mitral valve repair with the MitraClip delivery system for patients with mitral regurgitation and heart failure, a systematic literature search was conducted in various electronic databases to January 3, 2020. Eligibility criteria are the population (patients with mitral regurgitation (MR)), intervention (transcatheter mitral valve repair using the MitraClip), comparator (conventional medical treatment), outcomes, and designs (Model-based or trial-based full economic evaluations).The quality of included studies was assessed using the CHEERS checklist. Mortality and survival rate, quality-adjusted life year (QALY), life years gained (LYG), total cost, and the incremental cost-effectiveness ratio (ICER) regarding the use of MitraClip System were considered as the key outcomes. Eight articles were eligible for full-text assessment. Ultimately, a total of seven studies were considered in the current systematic review. Results demonstrated that MitraClip reduces mortality rate and increases survival rate. The mortality rate at 1 year and 10 years was 16.7% versus 29.77% and 70.9% versus 98.8%, respectively. Total cost data based on 2019 USD show that the MitraClip has the highest cost in the USA ($121,390) and the lowest cost in Italy ($33,062). The results showed that in all selected countries, willingness-to-pay (WTP) thresholds are upper than the cost per QALY; also, the highest ICER for the MitraClip is in the USA ($55,600/QALY) and the lowest in Italy ($10,616/QALY). To conclude, evidence from this systematic review suggests that MitraClip Delivery System improved both life expectancy and QALY compared with medical treatment in patients at high surgical risk and it was also a cost-effective treatment option for patients with mitral regurgitation.

Abstract
BACKGROUND The first two randomized control trials (RCTs) studying the role of MitraClip in patients with secondary mitral regurgitation (MR) had antagonizing results. We, therefore, performed an updated meta-analysis of RCTs and propensity score-matched observational studies investigating the role of MitraClips in patients with secondary MR. A novel method of Kaplan Meier Curve reconstruction from derived individual patient data will be used to compare the survival probability of control groups in COAPT and MITRA HF trail, and hence, access inter-study heterogeneity. METHODS Medline and Cochrane databases was used for systematic search. We used the Mantel-Haenszel method with a random-effect model to calculate risk ratio (RR) with 95% confidence interval (CI) and inverse variance method with a random-effect model to calculate the mean difference (MD) with 95% confidence interval (CI). We used a fixed-effect approach for meta-regression. RESULTS MitraClip reduced the risk of all-cause mortality [RR: 0.72, CI: 0.55-0.95, P value = 0.02, I2 = 55%, χ2P-value = 0.08] and readmission [RR: 0.62, CI: 0.42-0.92, P value = 0.02, I2 = 90%, χ2P-value<0.01] at two years follow-up. There was no effect of MitraClip on change in cardiovascular mortality and 6 m walking distance at 12 months follow-up. Meta-regression indicated left ventricular end diastolic volume and age among the factors affecting outcomes. Reconstructed Kaplan Meier curves confirmed considerable heterogeneity among patients randomized in MITRA HF and COAPT trial. CONCLUSION The present meta-analysis confirms the beneficial role of percutaneous mitral valve repair in patients with secondary MR. However, all the results were associated with considerable heterogeneity.

Abstract
Introduction The purpose of this meta-analysis is to compare the efficacy of MitraClip plus medical therapy versus medical therapy alone in patients with functional mitral regurgitation (FMR). FMR caused by left ventricular dysfunction is associated with poor prognosis. Whether MitraClip improves clinical outcomes in this patient population remains controversial. Methods We conducted an electronic database search of PubMed, CINAHL, Cochrane Central, Scopus, Google Scholar, and Web of Science databases for randomized control trials (RCTs) and observational studies with propensity score matching (PSM) that compared MitraClip plus medical therapy with medical therapy alone for patients with FMR and reported on subsequent mortality, heart failure re-hospitalization, and other outcomes of interest. Event rates were compared using a random-effects model with odds ratio as the effect size. Results Five studies (n = 1513; MitraClip = 796, medical therapy = 717) were included in the final analysis. MitraClip plus medical therapy compared to medical therapy alone was associated with a significant reduction in overall mortality (OR = 0.66, 95% CI = 0.44–0.99, P = 0.04) and heart failure (HF) re-hospitalization rates (OR = 0.57, 95% CI = 0.36–0.91, P = 0.02). There was reduced need for heart transplantation or mechanical support requirement (OR = 0.48, 95% CI = 0.25–0.91, P = 0.02) and unplanned mitral valve surgery (OR = 0.21, 95% CI = 0.07–0.61, P = 0.004) in the MitraClip group. No effect was observed on cardiac mortality (P = 0.42) between the two groups. Conclusions MitraClip plus medical therapy improves overall mortality and reduces HF re-hospitalization rates compared to medical therapy alone in patients with FMR.

The COAPT trial (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients With Functional Mitral Regurgitation) demonstrated that edge-to-edge transcatheter mitral valve repair (TMVr) with the MitraClip resulted in reduced mortality and heart failure hospitalizations and improved quality of life compared with maximally tolerated guideline-directed medical therapy (GDMT) in patients with heart failure and 3 to 4+ secondary mitral regurgitation. Whether TMVr is cost-effective compared with GDMT in this population is unknown.
Methods:
We used data from the COAPT trial to perform a formal patient-level economic analysis of TMVr+GDMT versus GDMT alone for patients with heart failure and 3 to 4+ secondary mitral regurgitation from the perspective of the US healthcare system. Costs for the index TMVr hospitalization were assessed using a combination of resource-based accounting and hospital billing data (when available). Follow-up medical care costs were estimated on the basis of medical resource use collected during the COAPT trial. Health utilities were estimated for all patients at baseline and 1, 6, 12, and 24 months with the Short Form Six-Dimension Health Survey.
Results:
Initial costs for the TMVr procedure and index hospitalization were $35 755 and $48 198, respectively. Although follow-up costs were significantly lower with TMVr compared with GDMT ($26 654 versus $38 345;
P
=0.018), cumulative 2-year costs remained higher with TMVr because of the upfront cost of the index procedure ($73 416 versus $38 345;
P
<0.001). When in-trial survival, health utilities, and costs were modeled over a lifetime horizon, TMVr was projected to increase life expectancy by 1.13 years and quality-adjusted life-years by 0.82 years at a cost of $45 648, yielding a lifetime incremental cost-effectiveness ratio of $40 361 per life-year gained and $55 600 per quality-adjusted life-year gained.
Conclusions:
For symptomatic patients with heart failure and 3 to 4+ secondary mitral regurgitation, TMVr increases life expectancy and quality-adjusted life expectancy compared with GDMT at an incremental cost per quality-adjusted life-year gained that represents acceptable economic value according to current US thresholds.

Abstract
BACKGROUND The benefit of percutaneous mitral valve repair (PMVR) in patients with secondary MR is still debated. We aimed to compare the outcome of PMVR with optimal medical therapy (OMT) versus OMT alone in patients with secondary mitral regurgitation (MR) and to assess the role of potential effect modifiers. METHODS We performed a systematic review and meta-analysis of 2 randomized clinical trials (RCT) and 7 non-randomized observational studies (nROS). Hazard ratios (HR) and 95% confidence intervals (CI) were pooled through inverse variance random-effects model to compute the summary effect size for all-cause death, cardiovascular death and cardiac-related hospitalization. Subgroup and meta-regression analysis were also performed. RESULTS An overall population of 3118 individuals (67% men; mean age, 73 years) was included: 1775 PMVR+OMT and 1343 OMT patients, with mean follow-up of 24 ± 15 months. PMVR+OMT was associated with a lower risk of all-cause death (HR: 0.77; 95% CI: 0.68-0.87), cardiovascular death (HR: 0.55; 95% CI: 0.34-0.89) and cardiac-related hospitalization (HR:0.77; 95% CI: 0.64-0.92). Meta-regression analysis showed that larger left ventricular end-diastolic volume index (LVEDVI) portends higher risk of all-cause death, cardiovascular death and cardiac-related hospitalization after PMVR (p < 0.001 for all). CONCLUSIONS This study-level meta-analysis shows that PMVR+OMT is associated with reduced all-cause death, cardiovascular death and cardiac-related hospitalization when compared with OMT alone in secondary MR. LVEDVI is a predictive marker of efficacy, as patients with smaller LVEDVI have been shown to derive the largest benefit from PMVR.

Abstract
BACKGROUND Functional mitral regurgitation (FMR) is a common finding among patients with heart failure (HF) and it is related to adverse events. Outcomes in patients undergoing transcatheter mitral valve repair (TMVR) are still a matter of debate. We performed a meta-analysis to assess mid- and long-term outcomes of patients with FMR treated with MitraClip® compared to medical management. METHODS We conducted an electronic database search of all published data PubMed Central, Embase, the Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and Google Scholar databases. The primary end-point was all-cause mortality. The secondary end-points were hospitalizations for HF, need for heart transplantation or left ventricular assist device, unplanned mitral valve surgery, myocardial infarction and stroke. RESULTS Five studies (n = 1513 patients) were included in the analysis. The summary estimate including all the available studies showed a statistically significant reduction in all-cause mortality favoring MitraClip® (HR 0.56, CI 95% [0.38-0.84]) and HF hospitalizations (HR 0.65; CI 95% [0.46-0.92]). A significant reduction in the indication for advanced HF therapies (OR 0.48; CI 95% [0.25-0.90]) or the need for unplanned mitral valve surgery (OR 0.20; CI 95% [0.07-0.57]) was also found in the group of patients that underwent TMVR. No differences in the incidence of myocardial infarction or stroke were found between both groups of treatment. No publication bias was detected. CONCLUSION TMVR with MitraClip® system was related to a significant reduction in all-cause mortality, hospitalizations for HF and the need for HF transplant, left ventricular assist device or unplanned surgery beyond 1-year follow up.

Abstract
Objectives To compare percutaneous mitral valve repair (PMVR) with optimal medical therapy (OMT) in patients with heart failure (HF) and severe functional mitral regurgitation (FMR). Background Many patients with HF and FMR are not suitable for surgical valve replacement and remain symptomatic despite maximal OMT. PMVR has recently emerged as an alternative solution. Methods We performed a systematic review and a meta-analysis to address this question. Cochrane CENTRAL, MEDLINE, and Scopus were searched for randomized (RCT) and nonrandomized studies comparing PMVR with OMT in patients with HF and FMR. Primary endpoint was all-cause midterm mortality (at 1 and 2 years). Secondary endpoints were 30-day mortality and cardiovascular mortality and HF hospitalizations, at maximum follow-up. Studies including mixed cohort of degenerative and functional MR were allowed initially but were excluded in a secondary sensitivity analysis for each of the study's end points. This meta-analysis was performed following the publication of two RCTs (MITRA-FR and COAPT). Results Eight studies (six observational, two RCTs) comprising 3,009 patients were included in the meta-analysis. In comparison with OMT, PMVR significantly reduced 1-year mortality (RR: 0.70 [0.56, 0.87]; p=0.002; I2=47.6%), 2-year mortality (RR: 0.63 [0.55, 0.73]; p<0.001; I2=0%), and cardiovascular mortality (RR: 0.32 [0.23, 0.44]; p<0.001; I2=0%). No significant difference between PMVR+OMT and OMT was noted in HF hospitalization (HR: 0.69 [0.40, 1.20]; p=0.19; I2=85%) and 30-day mortality (RR: 1.13 [0.68, 1.87]; p=0.16; I2=0%). Conclusions In comparison with OMT, PMVR significantly reduces 1-year mortality, 2-year mortality, and cardiovascular mortality in patients with HF and severe MR.

Abstract
OBJECTIVES To evaluate the safety and efficacy of percutaneous mitral valve repair for the management of functional mitral insufficiency. BACKGROUND Severe FMR is present in 25-30% of patients with heart failure and is an independent predictor of mortality and hospitalizations in patients with both ischemic and nonischemic cardiomyopathy. MitraClip therapy has been approved for high surgical risk patients with primary mitral regurgitation. Recent studies including two randomized trials have yielded conflicting results in terms of its clinical efficacy and outcomes for FMR. A quantitative evaluation and synthesis of this information are essential in elucidating the role of MitraClip repair for FMR. METHODS We performed a literature search using PubMed, EMBASE, and Cochrane Central Register of Controlled Trials from September 2008 to September 2018. Studies comparing percutaneous mitral valve repair using the MitraClip device against conservative therapy for the management of functional mitral regurgitation were included. RESULTS Seven studies with 1,174 patients in MitraClip group and 1,015 patients in medical therapy group met inclusion criteria. The 12-month mortality in the MitraClip group was 18.4% compared with 25.9% in the medical therapy group (odds ratio [OR]: 0.65 [0.50, 0.86]; p < .002). The rate of readmission at 12 months was 29.9% in the MitraClip group compared with 54.1% in the medical therapy group (OR: 040 [0.32-0.49]; p < .0001. The prognostic efficacy of MitraClip repair appears to be more substantial over longer follow-up period over medical therapy alone. CONCLUSIONS Based on the results of this meta-analysis, percutaneous mitral valve repair with MitraClip appears to be superior to medical therapy for symptomatic moderate-to-severe functional mitral insufficiency. Further clinical research is needed to identify the ideal patient subgroups who receive maximum benefit with the MitraClip therapy.

Abstract
AIMS Survival benefit of percutaneous mitral valve repair with the MitraClip over conservative treatment of functional mitral regurgitation (MR) remains unclear. The purpose of this meta-analysis is to compare survival outcomes of MitraClip with those of medical therapy in patients with functional MR. METHODS AND RESULTS A comprehensive literature search of PubMed, MEDLINE, and Google Scholar was conducted including studies evaluating MitraClip vs. medical therapy with multivariate adjustment and with >80% of patients with functional MR. Death from any cause was the primary endpoint, while freedom from readmission was the secondary one, evaluated with random effects. These analyses were performed at study level and at patient level including only functional MR when available, evaluating the effect of MitraClip in different subgroups according to age, ischaemic aetiology, presence of implantable cardioverter defibrillator/cardiac resynchronization therapy, and left ventricular ejection fraction and volumes. We identified six eligible observational studies including 2121 participants who were treated with MitraClip (n = 833) or conservative therapy (n = 1288). Clinical follow-up was documented at a median of 400 days. At study-level analysis, MitraClip, when compared with medical therapy (P = 0.005), was associated with significant reduction of death (P = 0.002) and of readmission due to cardiac disease. At patient-level analysis, including 344 patients, MitraClip confirmed robust survival benefit over medical therapy for all patients with functional MR and among the most important subgroups. CONCLUSIONS Compared with conservative treatment, MitraClip is associated with a significant survival benefit. Importantly, this superiority is particularly pronounced among patients with functional MR and across all the main subgroups.
