The choice between alcohol septal ablation and surgical myectomy for obstructive hypertrophic cardiomyopathy requires a highly individualized approach based on patient-specific and anatomical factors.
Hypertrophic cardiomyopathy (HCM) is characterized by the presence of increased thickness of the left ventricular wall that is not solely explained by abnormal loading conditions. Two-thirds of the patients with HCM have an obstruction in the left ventricle after provocation or even while at rest. This obstruction is associated with more symptoms and a worse prognosis. The two main therapeutic approaches for treating a left ventricular obstruction are alcohol septal ablation and surgical myectomy. Both these techniques are discussed in this article. Currently, the final decision concerning the optimal invasive therapy for patients with obstructive HCM must be individualized to each patient depending on his/her wishes and expectations, way of life, age, heart morphology, and hemodynamics, as well as the experience of the treating center.

Josef Veselka (2015) conducted a review in Hypertrophic cardiomyopathy with left ventricular obstruction. Alcohol septal ablation and surgical myectomy was evaluated. Alcohol septal ablation and surgical myectomy are the main therapeutic approaches for treating left ventricular obstruction in hypertrophic cardiomyopathy, requiring individualized patient selection.
