Transcatheter Myotomy for Left Ventricular Outflow Tract Obstruction.

The article focuses on introducing a new transcatheter myotomy technique, SESAME, aimed at addressing left ventricular outflow tract obstruction in patients with hypertrophic cardiomyopathy (HCM) and facilitating transcatheter valve replacement (TVR). It is reported that this innovative approach utilizes intramyocardial guidewires and electrosurgery to widen the LVOT (Left Ventricular Outflow Tract), improving symptoms in HCM and TVR patients.
