Between December 1994 and December 2002, surgical repair of aneurysm of the abdominal aorta (AAA) was performed in 139 patients, 32 of whom had ruptured AAA. Thirty-nine patients were 80 years old or older (O) and 100 patients were younger (Y) than 80. The ratio between ruptured and unruptured AAA was significantly higher among older patients (O: 41.0% versus Y: 16.0%, p=0.002). Surgical mortality was identical in those receiving elective repair (O: 0% versus Y: 0%) and similar in those receiving repair following rupture (O: 13.3% versus Y: 28.5%, p=0.314). A diagnosis of AAA had been made before rupture in only 10 patients, whose survival rate was relatively higher (100%) than that of patients without known AAA (66.7%). Ten patients died of ruptured AAA without surgery. Four of them had intractable cardiopulmonary arrest despite attempts at resuscitation. Four other patients were debilitated due to other disease even before rupture of AAA. Another 2 patients were diagnosed as ruptured AAA at autopsy. In conclusion, elective surgical repair is safe in elderly patients with AAA. The survival rate of elderly patients following rupture of AAA is comparable to that of younger patients. Some patients, however, should be excluded from aggressive treatment because of associated conditions such as marked debilitation prior to rupture or uncorrectable cardiopulmonary arrest on arrival. Patient selection is a sensitive but important issue in the era of society being composed of many elderly people.

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.
