Abstract
The intraoperative application of argon-laser irradiation for the treatment of hypertrophic cardiomyopathy (HC) represents the first successful use of laser light for the treatment of cardiovascular disease in a live patient [1]. Conventional surgical treatment for patients with HC who are refractory to medical therapy involves a left ventricular septal myotomy and myectomy (Morrow procedure) [2] or myotomy alone [3, 4]. Both operations are performed via a complete median sternotomy. Following institution of cardiopulmonary bypass, an aortotomy is created and the left ventricular outflow tract is visualized below the aortic valve. Retracting the valve cusps, an incision (myotomy) is then made in the thickened basal portion of the ventricular septum. The procedure as designed by Morrow includes removal of a relatively small piece (0.5–2.0 gm) of septal myocardium (myectomy).
