Atrial septal defect resulting from mitral balloon valvuloplasty: relation of defect morphology to transseptal balloon catheter delivery.

abstract：BACKGROUND:A previous randomized controlled trial evaluating the use of spironolactone in heart failure patients reported a low risk of hyperkalemia (2%) and renal insufficiency (0%). Because treatments for heart failure have changed since the benefits of spironolactone were reported, the prevalence of these complicati...
