Abstract
Operative intervention has been an important part of the therapeutic strategy for patients with obstructive hypertrophic cardiomyopathy (HCM) for the past 30 years [1–16]. Cleland [1], in 1958, was the first to successfully perform a transaortic myectomy operation in a patient with this disease by resecting a small amount of muscle from the thickened upper portion of ventricular septum. Shortly thereafter, Morrow [2, 3] modified and refined the ventricular septal myotomy-myectomy operation (also known as left ventricular myotomy-myectomy, ventriculomyectomy, or the Morrow procedure), which he ultimately performed on 350 patients at the National Institutes of Health. Abouth the same time, in Toronto, Bigelow et al. [4] successfully pioneered the myotomy operation (ventriculomyotomy) which was similar to the myotomy-myectomy except that no muscle was ultimately removed from the ventricular septum.
