Outcomes After Repeat Alcohol Septal Ablation in Patients With Obstructive Hypertrophic Cardiomyopathy.

ABSTRACT:

Background

Alcohol septal ablation (ASA) may necessitate a repeat procedure if the obstructive myocardium is not sufficiently ablated; however, the outcomes after repeat ASA are not well studied.

Objectives

The objective of the study was to evaluate outcomes in patients with obstructive hypertrophic cardiomyopathy after repeat ASA.

Methods

Of the 663 patients with obstructive hypertrophic cardiomyopathy who underwent ASA, 84 with repeat ASA were analyzed. Residual left ventricular (LV) obstruction was stratified according to proximal or distal obstruction. The primary outcome was the absence of symptomatic residual LV obstruction, defined as NYHA functional class I or LV gradient <50 mm Hg, or both at 12 months after repeat ASA.
