Parachute mitral valve. Demonstrates a case of a ‘Parachute’ Mitral Valve, in which all anchoring chordae tendineae supporting the mitral valve arise from a single papillary muscle. This is a consequence of abnormal fusion of myocardial trabeculae during delamination. (A,B) Apical four-chamber view using 2D echocardiography to show (A) the single anchoring papillary muscle and (B) color flow Doppler showing mitral regurgitation from the maladaptive tethering apparatus. (C) Cardiac MRI image showing the ‘Parachute’ mitral valve.
