Mitral valve repair in severe mitral regurgitation due to Barlow's disease with concomitant mitral annular disjunction: a case report.

ABSTRACT:

Background

Mitral annular disjunction (MAD) is characterized by the detachment of the mitral valve-left atrial junction from the left ventricular myocardium. The association of MAD with Barlow's disease and its relevance to treatment are increasingly recognized.

Case presentation

A 75-year-old male with a history of mitral regurgitation (MR) and ablation for paroxysmal atrial fibrillation was diagnosed with severe MR due to Barlow's disease, as confirmed by echocardiography. Imaging revealed disjunction at the mitral valve's posterior annulus. During surgery, the posterior leaflet was resected along the annulus with precise height adjustments. A 6-mm separation between the mitral valve-left atrial junction and the left ventricular myocardium was sutured using a four-stitch m
