Guideline-directed medical therapy assessment in heart failure patients undergoing percutaneous mitral valve repair.
Full text linkAIMS
Achieving optimized guideline-directed medical therapy (GDMT) is recommended prior to transcatheter mitral valve edge-to-edge repair (M-TEER) for secondary mitral regurgitation (SMR). We aimed to propose and validate an easy-to-use score for assessing the quality of GDMT in patients with heart failure with reduced ejection fraction (HFrEF) undergoing M-TEER.
METHODS AND RESULTS
Among the 1641 EuroSMR patients enrolled in the EuroSMR Registry who underwent M-TEER, a total of 1072 patients [median age 74, interquartile range (IQR) 67-79 years, 29% female] had complete data on GDMT and a left ventricular ejection fraction ≤ 40% and were included in the current study. We proposed a GDMT score that considers the dosage levels of three medication classes (angiotensin-converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitors, beta-blockers, and mineralocorticoid receptor antagonists), with a maximum score of 12 points indicating optimal GDMT. The primary outcome was all-cause mortality. The median GDMT score was 4 points (IQR 3-6). All three domains of the scoring system were associated with all-cause mortality (P < 0.05 for all). The overall GDMT score was associated with all-cause mortality (hazard ratio 0.90, 95% confidence interval 0.86-0.95 for each 1-point increase in the GDMT score). This association remained significant after adjusting for renal function and co-morbidities.
CONCLUSIONS
This study demonstrates the utility of a simple GDMT scoring system for assessing the adequacy of GDMT in HFrEF patients with relevant SMR undergoing M-TEER. The GDMT score has potential applications in guiding the design of future clinical trials and aiding clinical decision-making processes

Randomized investigation of the MitraClip device in heart failure: Design and rationale of the RESHAPE‐HF2 trial design
No full textAbstract
Aims
The safety and effectiveness of the MitraClip device to treat functional mitral regurgitation (FMR) has been tested in previous clinical trials yielding somewhat heterogeneous results in heart failure (HF) patients. Over time, the MitraClip device system has been modified and clinical practice evolved to consider also less severely diseased HF patients with FMR for this therapeutic option. The RESHAPE‐HF2 trial aims to assess the safety and effectiveness of the MitraClip device system on top of medical therapy considered optimal in the treatment of clinically significant FMR in symptomatic patients with chronic HF.
Methods
The RESHAPE‐HF2 is an investigator‐initiated, prospective, randomized, parallel‐controlled, multicentre trial designed to evaluate the use of the MitraClip device (used in the most up‐to‐date version as available at sites) plus optimal standard of care therapy (device group) compared to optimal standard of care therapy alone (control group). Eligible subjects have signs and symptoms of HF (New York Heart Association [NYHA] class II–IV despite optimal therapy), and have moderate‐to‐severe or severe FMR, as confirmed by a central echocardiography core laboratory; have an ejection fraction between ≥20% and ≤50% (initially 15–35% for NYHA class II patients, and 15–45% for NYHA class III/IV patients); have been adequately treated per applicable standards, and have received appropriate revascularization and cardiac resynchronization therapy, if eligible; had a HF hospitalization or elevated natriuretic peptides (B‐type natriuretic peptide [BNP] ≥300 pg/ml or N‐terminal proBNP ≥1000 pg/ml) in the last 90 days; and in whom isolated mitral valve surgery is not a recommended treatment option. The trial has three primary endpoints, which are these: (i) the composite rate of total (first and recurrent) HF hospitalizations and cardiovascular death during 24 months of follow‐up, (ii) the rate of total (i.e. first and recurrent) HF hospitalizations within 24 months, and (iii) the change from baseline to 12 months in the Kansas City Cardiomyopathy Questionnaire overall score. The three primary endpoints will be analysed using the Hochberg procedure to control the familywise type I error rate across the three hypotheses.
Conclusions
The RESHAPE‐HF2 trial will provide sound evidence on the MitraClip device and its effects in HF patients with FMR. The recruitment was recently completed with 506 randomized patients
Transcatheter Valve Repair in Heart Failure with Moderate to Severe Mitral Regurgitation

No full textABSTRACT Aim The RESHAPE‐HF2 trial is designed to assess the efficacy and safety of the MitraClip device system for the treatment of clinically important functional mitral regurgitation (FMR) in patients with heart failure (HF). This report describes the baseline characteristics of patients enrolled in the RESHAPE‐HF2 trial compared to those enrolled in the COAPT and MITRA‐FR trials. Methods and results The RESHAPE‐HF2 study is an investigator‐initiated, prospective, randomized, multicentre trial including patients with symptomatic HF, a left ventricular ejection fraction (LVEF) between 20% and 50% with moderate‐to‐severe or severe FMR, for whom isolated mitral valve surgery was not recommended. Patients were randomized 1:1 to a strategy of delivering or withholding MitraClip. Of 506 patients randomized, the mean age of the patients was 70 ± 10 years, and 99 of them (20%) were women. The median EuroSCORE II was 5.3 (2.8–9.0) and median plasma N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP) was 2745 (1407–5385) pg/ml. Most patients were prescribed beta‐blockers (96%), diuretics (96%), angiotensin‐converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor–neprilysin inhibitors (82%) and mineralocorticoid receptor antagonists (82%). The use of sodium–glucose cotransporter 2 inhibitors was rare (7%). Cardiac resynchronization therapy (CRT) devices had been previously implanted in 29% of patients. Mean LVEF, left ventricular end‐diastolic volume and effective regurgitant orifice area (EROA) were 31 ± 8%, 211 ± 76 ml and 0.25 ± 0.08 cm 2 , respectively, whereas 44% of patients had mitral regurgitation severity of grade 4+. Compared to patients enrolled in COAPT and MITRA‐FR, those enrolled in RESHAPE‐HF2 were less likely to have mitral regurgitation grade 4+ and, on average, HAD lower EROA, and plasma NT‐proBNP and higher estimated glomerular filtration rate, but otherwise had similar age, comorbidities, CRT therapy and LVEF. Conclusion Patients enrolled in RESHAPE‐HF2 represent a third distinct population where MitraClip was tested in, that is one mainly comprising of patients with moderate‐to‐severe FMR instead of only severe FMR, as enrolled in the COAPT and MITRA‐FR trials. The results of RESHAPE‐HF2 will provide crucial insights regarding broader application of the transcatheter edge‐to‐edge repair procedure in clinical practice.Abbott Fund https://doi.org/10.13039/10000004
Hospitalization of Symptomatic Patients With Heart Failure and Moderate to Severe Functional Mitral Regurgitation Treated With MitraClip

No full text: 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
