Abstract
|
|
|
Surgical treatment is possible for the obstructive form of hypertrophic cardiomyopathy and transaortic left ventricular septal myectomy and myotomy has been the procedure of choice. If coexisting intrinsic mitral valve disease exists, mitral
valve
replacement has been performed. But abnormal systolic anterior motion of anterior mitral leaflet(SAM) with intrinsic normal mitral valve disease is the typical feature of IHSS and we prefer not to replace mitral valve. 3 patients underwent
transaortic
myotomy and myectomy for IHSS with mitral regurgitation. 2 patients of them have coexisting intrinsic mitral valve diseases such as mitral valve vegetation and chorda rupture.
Concomittent mitral valve replacement were performed. 1 patient shows SAM of mitral anterior leaflet but has intrinsic normal mitral valve morphologically and transepicardial echocardiogram and direct monitoring of pressure gradient during the
operative
procedure gives better information for subsided mitral regurgitation. Post operative course during the 12 months follow-up was uneventful. (Korean J Thoracic Cardiovas Surg 1994; 27:313-7)
