Septal Myectomy and Mitral Valve Repair using Robotic Assistance
Introduction: The left ventricular outflow tract (LVOT) is adjacent to the anterior leaflet of the mitral valve. The patient in this video presented with obstructive symptoms of the LVOT. We attempted treatment for hypertrophy of the ventricular septum using robotic techniques.
Methods: Access to the LVOT and mitral valve were through the right chest and peripheral cannulation was used. The da Vinci™ Robotic System (Intuitive Surgical, Inc.) was used to resect the hypertrophied septum and repair the mitral valve. Myectomy was done after releasing the anterior mitral leaflet from the annulus. After myectomy, the anterior leaflet was reattached, and the mitral valve was repaired.
Results: Successful myectomy and mitral valve repair were done using robotic assistance. The patient made a full recovery.
Conclusions: Improved instrumentation and visualization allowed for precise excision of hypertrophied septum. Many procedures done by traditional approaches can be performed safely using robotic techniques.
