Transmitral Myectomy and How to Deal With Systolic Anterior Motion (SAM) in Hypertrophic Obstructive Cardiomyopathy
In this Masters of Cardiothoracic Surgery, Meier and colleagues outline their approach to transmitral myectomy and surgical management of systolic anterior motion in a case vignette of a 45-year-old male with hypertrophic cardiomyopathy. The technique combines a transmitral left ventricular myectomy and a resuspension of the anterior mitral leaflet with a partial, flexible annuloplasty. The perils and pitfalls of this technique are presented in this article, which is accompanied by a narrated video with operative footage.
