Summary

Thirty-one patients were folio wed-up 4 weeks to 11 years postoperatively after myectomy in the region of the interventricular septum for hypertrophic obstructive cardiomyopathy, (HOCM).

The surgical treatment of the HOCM resulted in an improvement in the subjective symptoms by one to two clinical grades (NYHA). Postoperatively, the gradient in the left ventricular outflow tract is considerably reduced or no longer demonstrable. Echocardiographically, an inverse motion of the interventricular septum (58%) frequently occurs postoperatively, the septum remaining considerably thickened; furthermore, a considerable decrease (53%) or a complete disappearance (37%) of the forward motion of parts of the mitral valve apparatus (SAM) is also seen. The end-systolic left ventricular diameter and the left ventricular outflow tract are clearly wider in the surgical patients than in the nonsurgical patients with HOCM. In no case was the transition to a dilatative cardiomyopathy observed.

In contrast to the changes brought about by surgery, the conservative treatment with propranolol of patients with HOCM had no recognizable effect on the echocardiogram.
