[A successful cryosurgical treatment of malignant ventricular tachycardia following left ventricular aneurysm]

A 61-year-old man underwent cryoablation in addition to aneurysmectomy and single aorto-coronary bypass for sustained ventricular tachycardia (VT) following left ventricular aneurysm. Two types of VT were observed clinically and electrophysiologically with programmed stimulation. During operation, VT was induced but could not be maintained on normothermic cardio-pulmonary bypass. Therefore cryoablation was performed on the two sites where the delayed potentials were recorded. Postoperatively recurrence of VT was never recognized clinically and electrophysiologically.
