“…Unileaflet mitral valve is the rarest kind of congenital mitral valve anomalies (2). This anomaly, which is mostly due to hypoplastic PMVL, is often fatal in infancy without any surgical intervention due to severe mitral regurgitation (2,3). There are some adult case reports regarding unileaflet mitral valve due to hypoplasia of posterior mitral leaflet without severe MR who were identified just after auscultation of systolic murmur during check-up physical examination (4,5).…”

Introduction: Congenital malformation of mitral valve could encounter in isolation or with other congenital heart diseases. Objectives: Here, we report a case of congenital hypoplastic anterior mitral valve leaflet (AMVL). Methods: A 30-year-old male with a history of diabetes mellitus was referred with pleuritic chest pain since the previous day. He was admitted with impression of pericarditis. Trans thoracic echocardiography showed no pericardial effusion with incidental finding of lipomatous change of mitral valve annulus and hypoplastic AMVL with mild to moderate mitral regurgitation. Results: Cardiac magnetic resonance imaging showed thickening and fibrosis replacement of intervalvular fibrosa which extended to AMVL and resulted in restricted mitral valve annulus (12.4 mm) with subsequent restricted MV opening without significant mitral stenosis or regurgitation. These data were in favor of congenital hypoplastic MV annulus. Conclusions: Hypoplastic AMVL with restricted mitral valve annulus is a rare cause of mitral valve malformation and could be well tolerated since adulthood with good prognosis.
