Robotic endoscopic transmitral septal myectomy and concomitant mitral valve repair for hypertrophic obstructive cardiomyopathy

Hypertrophic obstructive cardiomyopathy is a disease of the heart in which the patient develops left ventricular outflow tract obstruction due to the interaction of the mitral valve and the intraventricular septum. Although septal myectomy remains the gold standard treatment for hypertrophic obstructive cardiomyopathy, several other approaches have been described in the literature, such as a transaortic, transapical or transmitral approach via a sternotomy. All of these approaches have been shown to produce reliable reduction in left ventricular outflow tract gradients. Robotic-assisted cardiac surgery has recently become a safe and effective alternative approach to a sternotomy for several intracardiac procedures, especially mitral valve repair and, in experienced centres, septal myectomy.
