Echo analysis of the left atrium and mitral annulus also showed that use of the MitraClip was associated with significant positive remodeling. In a multivariable analysis, postprocedural MR grade ≥ 2+ ...

We describe two siblings with a homozygous loss-of-function variant in CORIN. Both presented with cardiomyopathy, hypertension, fibrosis, and arrhythmia isolated to the left atrium.

A novel transcatheter-implanted system that shunts blood flow from the left to right atrium through the coronary sinus has shown an incremental clinical benefit from the 1-year to 2-year follow-up.

Atrial cardiopathy, characterized by abnormal size and function of the left atrium, has been associated with an increased risk of stroke and atrial fibrillation (AF), and because both stroke and ...
