Septal myectomy and mitral plication through a transaortic approach.

Currently, the gold standard treatment for hypertrophic cardiomyopathy in its obstructive variant is a wide septal myectomy through a transaortic approach. In some cases, where mitral regurgitation is added to septal hypertrophy due to systolic anterior movement of the anterior leaflet, concomitant procedures are proposed for the resolution of both. In this tutorial, we present a case of hypertrophic cardiomyopathy with associated systolic anterior movement that was resolved with septal resection and plication of the anterior leaflet of the mitral valve via a transaortic approach.
