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.

Multicenter StudyImproved Outcomes of Heart Transplantation in Adults With Congenital Heart Disease Receiving Regionalized Care.
The number of adult congenital heart disease (CHD) patients undergoing heart transplantation is increasing rapidly. CHD patients have higher surgical risk at transplantation. High-volume adult CHD transplant centers may have better transplant outcomes. ⋯ Designated expertise in CHD care is associated with improved waitlist outcomes for CHD patients listed for transplantation. Post-transplant survival was improved at the highest volume regional center. These findings suggest a possible advantage of regionalization of CHD transplantation.

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. (Efficacy and Safety of LCZ696 Compared to Valsartan, on Morbidity and Mortality in Heart Failure Patients With Preserved Ejection Fraction [PARAGON-HF]; NCT01920711).

Multicenter StudyImprovement in Pediatric Cardiac Surgical Outcomes Through Interhospital Collaboration.
Patients undergoing complex pediatric cardiac surgery remain at considerable risk of mortality and morbidity, and variation in outcomes exists across hospitals. The Pediatric Cardiac Critical Care Consortium (PC4) was formed to improve the quality of care for these patients through transparent data sharing and collaborative learning between participants. ⋯ This analysis demonstrates improving cardiac surgical outcomes at children's hospitals participating in PC4. This change appears unrelated to secular improvement trends, and likely reflects PC4's commitment to transparency and collaboration.

Multicenter Study Observational StudyLong-Term Cardiovascular Risk in Women With Hypertension During Pregnancy.
History of a hypertensive disorder of pregnancy (HDP) among women may be useful to refine atherosclerotic cardiovascular disease risk assessments. However, future risk of diverse cardiovascular conditions in asymptomatic middle-aged women with prior HDP remains unknown. ⋯ Hypertensive disorders of pregnancy are associated with accelerated cardiovascular aging and more diverse cardiovascular conditions than previously appreciated, including valvular heart disease. Cardiovascular risk after HDP is largely but incompletely mediated by development of chronic hypertension.
