Small left ventricular aneurysms in patients with ventricular tachyarrhythmias and normal coronary arteriograms.

Abstract

To the Editor: Ouyang et al1 report on 4 patients with recurrent exercise-induced syncope attributable to fast ventricular tachycardia, aneurysms in the inferior-lateral wall of the left ventricle, and a peculiar subepicardial arrhythmogenic substrate. The authors speculate that this presentation may constitute a distinct clinical syndrome and may be amenable to epicardial catheter ablation. A recent study has demonstrated that inflammatory left ventricular microaneurysms, often of viral origin, can be a cause of idiopathic ventricular tachyarrhythmias.2 Additionally, we recently reported a case of left ventricular microaneurysms as a cause of apparently idiopathic ventricular fibrillation in a 36-year-old woman.3 Both the study by Chimenti et al …
