Randomized Controlled Trial Multicenter StudyEchocardiographic Outcomes After Transcatheter Leaflet Approximation in Patients With Secondary Mitral Regurgitation: The COAPT Trial.
In the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation) trial among patients with heart failure (HF) and moderate-to-severe (3+) or severe (4+) secondary mitral regurgitation, patients treated with transcatheter mitral valve repair (TMVr) through leaflet approximation had reduced rates of HF hospitalization and mortality compared with guideline-directed medical therapy (GDMT) alone. ⋯ HF patients in the COAPT trial with 3+ or 4+ secondary mitral regurgitation, selected using strict echocardiographic criteria, benefitted from TMVr with reduced 2-year rates of death and HF hospitalization. Strict application of these echocardiographic criteria should enable the COAPT results to be translated to clinical practice.

Randomized Controlled Trial Multicenter StudyEchocardiographic Features of Patients With Heart Failure and Preserved Left Ventricular Ejection Fraction.
The PARAGON-HF (Prospective Comparison of ARNI With ARB Global Outcomes in HF With Preserved Ejection Fraction) trial tested the efficacy of sacubitril-valsartan in patients with heart failure with preserved ejection fraction (HFpEF). Existing data on cardiac structure and function in patients with HFpEF suggest significant heterogeneity. ⋯ Diastolic dysfunction, left atrial enlargement, and pulmonary hypertension were common in PARAGON-HF. LV hypertrophy, elevated left- and right-sided pressures, and right ventricular enlargement were independently predictive of incident heart failure hospitalization or cardiovascular death. Echocardiographic differences among HFpEF trials despite similar clinical event rates highlight the heterogeneity of this syndrome.
