Three Achilles’ heels of alcohol septal ablation

Abstract

<p>This manuscript looks at basic limitations of alcohol septal ablation in obstructive hypertrophic cardiomyopathy. They include high-grade atrioventricular blockages, residual obstructions of the left ventricular outflow tract and the so-called proarrhythmic effects of alcohol septal ablation procedure. All these weaknesses are reviewed in the context of incidence, etiology, and prevention.</p><p>Received 25 February 2017.

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

“…According to current literature data, the recurrence of residual obstruction after ASA in patients with HOCM varies from 15 to 28%. However, most authors do not indicate the exact number of patients with residual obstructions, but just the number of re‐interventions …”
