Surgical myectomy remains the gold standard treatment for critically symptomatic patients with hypertrophic obstructive cardiomyopathy sixty years after its pioneering introduction.
Surgical myectomy remains the gold standard treatment for highly symptomatic patients with hypertrophic obstructive cardiomyopathy.
A peak gradient ≥50 mmHg and advanced symptoms expressed as New York Heart Association (NYHA) classess III/IV, angina and/or syncope are acknowledged indications to surgically treat hypertrophic obstructive cardiomyopathy (HOCM). This is still a relatively neglected disease despite surgical myectomy has shown extreme efficacy since it was introduced by Morrow and Brockenbrough in 1961.(1) Over the past six decades, credit went to Morrow and Brockenbrough, although Kirklin and Ellis also published their first experience with resection of diffuse subaortic stenosis through the left ventricle.(2) There were only a couple of months difference in the chronology of these pioneering contributions and both groups reported surgery in critically symptomatic young patients. This is the gold standard sixty years later.
