Outcomes of hypertrophic obstructive cardiomyopathy patients undergoing alcohol septal ablation with a standard 3 mL dose of ethanol: Focus on long-term safety.

Objectives: The objective of this research was to assess the long-term results of alcohol septal ablation in patients with hypertrophic obstructive cardiomyopathy (HOCM), with all of them receiving a standard 3 mL ethanol dose.

Background: Generally, ethanol (0.5-3 mL) is infused depending on a septal artery width or interventricular septum (IVS) thickness during alcohol septal ablation.

Results of Ten-Year Follow-Up of Alcohol Septal Ablation in Patients with Obstructive Hypertrophic Cardiomyopathy.

This study looks at 10-year follow-up outcomes of alcohol septal ablation in patients with obstructive hypertrophic cardiomyopathy. Between 2000 and 2008, 40 patients with obstructive hypertrophic cardiomyopathy (27 males, 13 females) underwent alcohol septal ablation. The median follow-up period was 123 (2-179) months.
