Massive mitral regrgitation from chordal rupture and coronary artery disease.
The precise mechanism that causes spontaneous rupture of chordae tendineae remains unknown. That it may occur in patients with no disease other than underlying or associated coronary artery occlusion has not been previously reported. Six patients with chordal rupture were found among 600 patients who underwent operation for mitral regurgitation in a 6-year period. All 6 patients without exception underwent simultaneous mitral valve replacement and coronary revascularization. The salient clinical features of these patients are summarized, and 1 case is reported in detail.
