[Compression of the coronary trunk by aneurysm of the antero-left Valsalva sinus associated with acute mitral insufficiency caused by rupture of the chordae following valvular prolapse. Successful triple surgical operation in a 66-year old patient]

Tearing of the chordae is a common complication of prolapse of the mitral valve; which becomes increasingly common with age. In contrast, aneurysm of the Valsalva sinus is rare in patients over 65 years of age. The antero-left sinus is an unusual location, but may be complicated by compression of the left coronary artery, which is reported in 16 cases in the literature. The case reported is unusual due to the combination in a 66-year old subject of acute mitral incompetence, due to tearing of the chordae following prolapse of the mitral valve, and an aneurysm pressing on the coronary trunk whilst remaining asymptomatic. Complete correction of the lesions was successfully achieved by surgery.
