Two cases of vein patch angioplasty for ischemic heart disease were presented. The first case (59-year-old female) admitted to our hospital because of posterolateral infarction. Preoperative coronary angiogram (CAG) showed stenosis of 4-PD of RCA, proximal LAD and distal LCX. The second case (62-year-old male) admitted for operation of abdominal aortic aneurysm. Preoperative CAG showed stenosis of proximal RCA and mid LAD. Stenosis of 4-PD and proximal RCA was relieved by patch angioplasty using saphenous vein graft and coronary artery bypass to LAD was performed by left internal thoracic artery graft. Both cases showed successful enlargement of RCA stenosis and good graft patency at the postoperative CAG. Vein patch angioplasty is thought to be an alternative method for coronary revascularization to ischemic heart disease.

Improved technique in coronary artery surgery has allowed coronary artery bypass graftings (CABG) to be placed on beating heart. The effects of extracorporeal circulation and cardiac arrest are eliminated. From Jan. 1991 to June, 1992, we performed CABG surgery without cardiopulmonary bypass and cardiac arrest in 15 patients; the age ranged from 47 to 82 years with the mean of 65. Patients who had LAD and/or RCA stenosis were candidate of this procedure in early series. However in recent series, we extended the candidate to three-vessel or LMT stenosis cases who were considered ineligible for standard CABG because of renal failure or poor left ventricular function. Distal anastomoses were performed with interruption of coronary flow. From one to two distal anastomosis to the LAD and/or RCA (mean 1.4/patient) were performed. The ITA was used in all 15 patients. Combined cardiac or vascular operation was performed in 5 patients (AAA repair, TAA repair, carotid endarterectomy or coronary endarterectomy). There were no deaths and no perioperative myocardial infarction. Postoperative angiography were performed in 12 patients with a patency rate of 89%.

A 69-year-old man was referred to us with the diagnosis of abdominal aortic aneurysm (7 cm in diameter). Additionally his coronary arteriogram showed severe stenosis (LMT 75% and #6 99% delay). Because his ascending aorta was calcified severely, double CABG (LITA to LAD and RGEA to PL) was carried out in hypothermic ventricular fibrillation. Abdominal aortic aneurysm was replaced thereafter while the patient was still on cardiopulmonary bypass. His postoperative courses was satisfactory. In cases requiring early operation for both myocardial ischemia and abdominal aortic aneurysm, one stage operation was recommended. When atherosclerotic changes in the ascending aorta were severe, in situ arterial bypass grafting for ischemic heart disease under hypothermic ventricular fibrillation was useful.

The clinical experiences of 29 consecutive MIDCAB procedures performed at our institution between October, 1996, and October, 1997, were analyzed. Preoperative patient's characteristics were as follows; LAD single vessel disease: 25, double vessel disease: 1, triple vessel disease: 1, RC single vessel disease: 1, LMT lesion: 1, concomitant procedures: 2 (ASO: 1, AAA: 1). LITA harvesting was performed using the video-assisted thoracoscopy in initial 4 patients, and in last 10 patients we used the specially designed retractor THORALIFT (Autosuture Co., Ltd.) for harvesting LITA by direct vision. LAD was stabilized mechanically using the stabilizer when we performed the anastomosis in last 10 patients to enhance the quality of the anastomosis. The patency rate was 96%, but there were two patients (6%) who had the stenosis of the anastomosis site. Coronary artery occlusion time was 13.2 minutes in the mean. We also studied the hemodynamics of blood flow in LITA grafts with the aid of 7.5 MHz transthoracic duplex imaging in these MIDCAB patients and compared with the LITA grafts in conventional CABG performed in same periods. There were no statistical differences between the two groups about the graft flow and velocity. We conclude that MIDCAB would be an alternative procedure that can be performed with low risk and acceptable early results in selected patients.
