Three-Dimensional Transesophageal Echocardiography in the Anatomical Assessment of Isolated Parachute Mitral Valve in an Adult Patient.

Parachute mitral valve (PMV) is a rare congenital anomaly of the mitral valve apparatus usually evidenced in infants and young children. Adult presentation is extremely rare and is generally mild in terms of mitral stenosis. A 73-year-old woman was admitted to the emergency department due to progressive dyspnea, with NYHA functional class IV symptoms on presentation.
