Severe functional mitral regurgitation arising from isolated annular dilatation.
Functional mitral regurgitation or functional tricuspid regurgitation most commonly result from maladaptive remodeling due to ischemic heart disease or idiopathic dilatative cardiomyopathy. We report a case of significant functional mitral regurgitation and functional tricuspid regurgitation arising from isolated annular dilatation secondary to atrial fibrillation and associated atrial remodeling. The patient underwent successful mitral and tricuspid valve repair and a bi-atrial Maze procedure.
