Mitral valve repair with neo-chordae.

A 56-year-old male patient presented with an isolated posterior mitral leaflet (PML) prolapse due to degenerative mitral valve (MV) disease. The preoperative transthoracic echocardiography showed severe mitral regurgitation (MR) due to a flail P2 segment. Echocardiographic examination revealed a normal left ventricular ejection fraction of 67%, the mitral annulus with a diameter of 39 mm and normal right ventricle contractility with a tricuspid annular plane systolic excursion (TAPSE) of 38 mm. The vena contracta was measured to be 0.8 cm and the effective regurgitant orifice area (EROA) was 0.7 cm. The left atrium was slightly enlarged at 23 cm. The patient was in New York Heart Association functional class II. His medical history was otherwise unremarkable.
