Over the past 50 years, improvements in surgical techniques and expanded understanding of hypertrophic cardiomyopathy (HCM) and its pathophysiology have led to the current era in which septal myectomy has excellent, reproducible results. Based on formal guidelines, those patients with symptomatic obstructive HCM who have failed medical management and have left ventricular outflow gradients of >50 mmHg should be considered for septal myectomy. A better understanding of septal myectomy in terms of echocardiographic evaluation, operative techniques, and reported outcomes is critical in treating this heterogeneous and complex disease.

摘要

Over the past 50 years, improvements in surgical techniques and expanded understanding of hypertrophic cardiomyopathy (HCM) and its pathophysiology have led to the current era in which septal myectomy has excellent, reproducible results. Based on formal guidelines, those patients with symptomatic obstructive HCM who have failed medical management and have left ventricular outflow gradients of >50 mmHg should be considered for septal myectomy. A better understanding of septal myectomy in terms of echocardiographic evaluation, operative techniques, and reported outcomes is critical in treating this heterogeneous and complex disease.
