Video-assisted thoracoscopic transaortic myectomy for hypertrophic obstructive cardiomyopathy.

Abstract Hypertrophic obstructive cardiomyopathy remains one of the more common inherited cardiac disorders with often a major impact on quality of life. Even today, most frequently a sternotomy is performed to conduct the myectomy. Several minimally invasive procedures, under direct vision or via transmitral access, have been demonstrated to operate these patients. However, we believe our video-assisted transaortic approach could provide a more precise and complete resection than other minimal invasive approaches, because of a clearer visualization of the septum and outflow tract. This could further increase the benefits for these patients and potentially make more frail patients eligible for surgery.
