Abstract:
A 68-year-old man underwent percutaneous transluminal coronary angioplasty (PTCA) to left anterior descending artery (LAD) seg 7 after acute anteroseptal myocardial infarction 8 years previously. He was admitted because of syncope attack due to sustained ventricular tachycardia and subsequent fibrillation. He was treated medically in the ICU after cardiopulmonary resuscitation. Medical treatment with amiodarone and lidocaine was not successful and he was transferred to our hospital for surgical treatment of malignant ventricular tachycardia (VT) associated with left ventricular aneurysm and acute cholecystitis that occurred during admission. Left ventriculogram showed left ventricular aneurysm (ejection fraction: 35%) without any significant coronary lesions. The patient successfully underwent a Dor operation (left ventriculoplasty), double encircling endocardial cryoablation without endocardial resection, and preoperative and intraoperative endocardial mapping. Cholecystectomy was simultaneously performed after complete closure of the median chest incision. The recurrence of VT was never recognized clinically or electrophysiologically. The extended encircling endocardial cryoablation without endocardial resection and preoperative and intraoperative electrophysiological study, was a simple and effective method for ventricular tachycardia.
