Changes in left atrial function, left ventricle remodeling, and fibrosis after septal myectomy for obstructive hypertrophic cardiomyopathy.
This study aimed to investigate the impact of septal myectomy on left atrial function, left ventricle remodeling, and fibrosis in patients with obstructive hypertrophic cardiomyopathy. ⋯ Septal myectomy alleviated left ventricle hypertrophy and reversed left atrium and left ventricle remodeling in patients with obstructive hypertrophic cardiomyopathy. Late gadolinium enhancement in the left ventricle increased despite myectomy in patients with obstructive hypertrophic cardiomyopathy.

Randomized Controlled TrialVentricular reshaping with a beating heart implant improves pump function in experimental heart failure.
The left ventricle remodels from an ellipsoidal/conical shape to a spherical shape after a myocardial infarction. The spherical ventricle is inefficient as a pumping chamber, has higher wall stresses, and can lead to congestive heart failure. We sought to investigate if restoring physiological ventricular shape with a beating heart implant improves pump function. ⋯ Reshaping a postinfarction, failing left ventricle to restore its physiological conical shape significantly improves long-term pump function.
