Key Words: Intra aortic balloon pump Papillary muscle Triple coronary bypass
The patient, a 64yearold male, presented to hospital because of ongoing chest pain. He was endotracheally intubated because of hypoxemic respiratory failure, and taken to the cardiac catheterization suite where his circumflex coronary artery was stented and an intra aortic balloon pump (IABP) inserted. Because moderate mitral regurgitation was noted, a transesophageal echocardiogram was subsequently performed. Findings included an akinetic inferior wall, rupture of the postero-medial papillary muscle, and a flail anterior mitral leaflet. (Fig. 1A)
. The following day the patient was taken to the operating room. The mitral valve was exposed through a right atrial incision, and the ruptured papillary muscle identified (Fig. 1B). The native mitral valve was excised and a 31 mm St. Jude's mechanical mitral prosthesis inserted. A triple coronary bypass was performed. The following day the patient was extubated and the IABP removed. He has made a satisfactory recovery.
