title: [Holosystolic mitral valve prolapse and "SAM" after surgical treatment of hypertrophic obstructive cardiomyopathy (author's transl)].
abstract: In a 49-year-old male patient surgical treatment of hypertrophic obstructive cardiomyopathy (HOCM, clinical grade III, NYHA) by means of transaortic myotomy and myectomy was performed in November 1979. 6 months later the M-mode-echocardiogram revealed a distinct systolic anterior motion of parts of the mitral valve apparatus (SAM) as well as a marked holosystolic mitral valve prolapse (MVP). The two-dimensional echocardiographic examination demonstrated that the "SAM"-phenomenon was caused solely by chordae tendineae of the anterior mitral leaflet, while the prolapse was due to the posterior mitral leaflet itself.
