Safe and Effective Ultrasound-guided Myectomy and Mitral Valve Repair for HCM.

Surgery for obstructive hypertrophic cardiomyopathy with mitral abnormality requires a combined procedure of myectomy and mitral leaflet plication for relieving mitral systolic anterior motion and left ventricular outflow tract obstruction. We report a combined procedure of myectomy using intracardiac high-resolution ultrasonography and mitral bileaflet shortening in obstructive hypertrophic cardiomyopathy. Stepwise real-time verification of residual ventricular mass using high-resolution ultrasonic probe would be a potent addition to our armamentarium. This modality provides safe and effective myectomy, which has been a most technically challenging surgical procedure especially for inexperienced surgeons.
