Hypoplasia of the posterior mitral valve leaflet is a rare congenital condition that can present in adulthood with severe mitral regurgitation and can be diagnosed using 2D and 3D transesophageal echocardiography.
May aid TEE diagnosis of rare adult mitral anomalies; leaves open need for larger validation before practice change.
Hypoplasia of the posterior mitral valve leaflet (PMVL) is a rare congenital heart disease, usually presenting in infancy and childhood with severe mitral regurgitation, either in isolation or associated with other cardiac lesions. We report a case of a 69-year-old woman with recent-onset exertional dyspnea and severe mitral regurgitation. Two- and three-dimensional transesophageal echocardiography showed severe hypoplasia of the PMVL, confirmed by surgical inspection.
