Abstract

Fifty patients with anteroapical left ventricular aneurysm secondary to prior myocardial infarction underwent aneurysmectomy, at which time endocardial sinus rhythm mapping was performed. Forty patients had a history of recurrent sustained monomorphic ventricular tachycardia, and 10 had an aneurysm hot no history of spontaneous sustained tachycardia. A comparison of the clinical, angiographic and sinus rhythm endocardial clectrographic characteristics of these two groups revealed that the patients without spontaneous ventricular tachycardia had more severe coronary artery disease (2.6 ± 0.5 versus 1.9 ± 0.8 coronary arteries having >70% stenosis; p <0.03), underwent surgery earlier after infarction (3 ± 2 versus 46 ± 53 months; p <0.003) and had less extensive wall motion abnormalities on contrast ventriculography (0 of 8 versus 13 of 35 patients assessed had an abnormally contracting ventriculographic segment length >60%; p <0.04). During intraoperative programmed electrical stimulation, all 40 patients with and 4 of 10 without a history of spontaneous ventricular tachycardia had induciblc tachycardia. The patients with inducible tachycardia had a larger area of endocardium from which abnormal electrograms (duration >70 ms or amplitude 90 ms, amplitude
