Retrospectively, the first 143 patients who were operated on with bilateral internal thoracic arteries (BITA group) were matched with 143 patients operated on with only one left internal thoracic artery anastomosed on the left anterior descending artery and additional vein grafts (LITA group) and followed up for a maximum of 8 years. At 5 years follow-up there were no significant differences in event-free survival between the groups. After 8 years, the overall survival was 96% and 92% (not significant [NS]), cardiac survival 99% and 97% (NS), angina-free cardiac survival 51% and 35% (NS), infarction-free cardiac survival 95% and 78% (NS), reintervention-free cardiac survival 87% and 88% (NS), and all cardiac event-free survival 49% and 31% (NS) for the BITA and LITA groups, respectively. The incidence of late pulmonary, wound, and other complications was comparable. Cox proportional hazards analysis showed that a higher left ventricular end-diastolic pressure and female sex were predictors of recurrent angina and late cardiac events. During this intermediate-term follow-up, the use of one or two internal thoracic arteries was of no value in predicting angina-free or cardiac event-free survival.

Free arterial grafts were aggressively placed in 39 patients (1991 to 1993). There were 34 males and 5 females, and mean age was 59.9 year old. Of 85 arterial grafts, 41 were free grafts, and their materials included left and right internal thoracic artery (LITA, RITA) and right gastroepiploic artery (GEA). There were one free LITA-left anterior descending coronary artery (LAD), seven free RITA-LAD, three free RITA-diagonal branch (Dx), 14 free RITA-left circumflex coronary artery (LCX), 10 free RITA-right coronary artery (RCA), two sequential RITA-Dx-LCX, one free GEA-Dx, two free GEA-LCX, and one free GEA-RCA bypass. Of 41 free arterial grafts, 38 were in the aorta-coronary position, and the proximal anastomosis was constructed first under single aortic cross-clamping to get the larger anastomotic sites for both at the proximal and distal ends of the arterial graft. The proximal sites of the remaining 3 arterial grafts were placed to concomitantly utilized saphenous vein grafts in two patients and RCA in one patient because of their shortness. Perioperative complications included no exploration for bleeding, myocardial infarction in one (2.6%), intra-aortic balloon pumping in three (7.7%), and wound complications in two (5.1%). 28 cases (72%) were completely revascularized with only arterial grafts. Of 41 free arterial grafts studied within one month after operation, all grafts were patent. All patients were free from angina after a 27 months mean follow-up. We believe that the proximal anastomosis technique for free arterial graft we used could be acceptable alternative for many surgeons. These excellent results justify wider use of free arterial grafts.

The incidence of reoperative coronary artery bypass grafting (reCABG) is recently increasing. However, there has been no report of reCABG in patients with patent internal thoracic artery (ITA) grafts in Japan. We performed reCABG in three such patients with patent ITA grafts. The first patient was a 49-year-old male who had undergone a 2 CABG (left ITA-LAD, SVG-DX 1), 8 years and 7 months prior to the 2nd operation, he received a re 2 CABG (GEA-RCA, RITA-SVG-DX 1) with a patent prior LITA-LAD graft. The second patient was a 65-year-old female who had undergone CABG in which the LITA had been erroneously anastomosed to the DX 2 in place of the LAD. Three year later, the reCABG (RITA-LAD) was performed with a patent prior LITA-DX 2 graft. The third patient was a 51-year-old male who had undergone 3-CABG (RITA-LAD, LITA-DX, SVG-RCA). The RITA was closed most probably due to technical errors and his angina recurred. Tree year after the first operation, he received a re 3-CABG (GEA-LAD, SVG-RCA, SVG-OM) with a patent prior LITA-DX graft. In each patient, PTCA had been tried twice, twice and once prior to redo operations. Their post-redo courses were uneventful, and they were discharged free from angina. In such cases it is important to manage with care the patent ITA grafts at reoperation. Biplane ITA angiograms are quite helpful to evaluate the course of grafts in relation to the sternum. To cover the ITA graft with a GORE-TEX membrane may also be useful for easy identification of the graft at redo operations.

A 54-year-old male with a left ventricular aneurysm and angina after myocardial infarction underwent Cooley's ventricular endoaneurysmorrhaphy with single coronary artery bypass grafting. On cardiopulmonary bypass, an elliptial Dacron felt patch was fashioned to replace the diseased area in the left ventricular cavity, restoring normal shape, contour and volume to the ventricule and stabilizing the still viable and functioning myocardium, and sutured to transition zone between viable myocardium and the fibrotic scarred area. At this time, single coronary bypass grafting (LITA to diagonal branch) was done. His post operative course was uneventful. The left ventricular systolic and diastolic function improved significantly in each variable measured on left ventriculogram analysis.

36 consecutive patients (male:female = 33:3, mean age 57.3) underwent sequential coronary artery bypass grafting (CABG) utilizing the left internal thoracic artery (LITA, n = 30), right gastroepiploic artery (RGEA, n = 8) as in situ grafts. Two patients received sequential bypass grafting with both grafts simultaneously. No right internal thoracic arteries were used except for one as a free nonsequential graft. Taking into account the adjunctive venous anastomoses and the arterial nonsequential anastomoses, there were 3.5 anastomoses per patients. Proxymal side-to-side anastomosis of LITAs were all constructed on the diagonal branches except for one on the proxymal Left Anterior Descending Coronary Artery (LAD), whereas that of the RGEAs were on the proxymal Right Coronary Artery (RCA) (2), distal RCA (6) or distal circumflex (1). Distal end-to-side anastomoses of LITAs were all on the LAD, and those of the RGEAs were on the distal RCA (3) or distal circumflex artery (5). Proxymal side-to-side anastomoses were always performed first, allowing us to assess the distal flow through the graft before we anastomose it to the distal branch. We routinely obtain a preoperative angiogram of the arterial grafts, which enable us to fully assess the suitability of the arteries as in situ grafts. There were no perioperative deaths, nor perioperative myocardial infarctions, however, two patients died of extracardiac causes at 42 and 68 days after operation respectively. For the thirty four survivors, followup was complete (4-49 months, average 12.3 months). One still had angina of Canadian Cardiovascular Society Classification (CCSC) class 2, and 33 were free of angina.(ABSTRACT TRUNCATED AT 250 WORDS)

The current trend in myocardial revascularization is to use arterial grafts in most, if not all cases. The right internal thoracic artery was a logical choice once the left internal thoracic artery patency on the LAD was known. This study presents our experience of using both attached internal thoracic arteries (ITA). Between January and October 1990, 159 myocardial revascularizations were performed in our department. In 117 cases, bilateral ITA grafting was used with non exclusion criteria. There were 100 male and 17 female patients, with a mean age of 61 +/- 8. The LITA was anastomosed to the LAD in 44 cases, and to the marginal artery in 74. The RITA was anastomosed to the LAD in 68 cases, to the marginal artery in 47 and to the right coronary artery in 2. An average of 3.5 bypasses per patient, including saphenous vein grafts, were performed. Six patients (5%) died within 30 days. Four patients (3.4%) were diagnosed as having periperative myocardial infarcts. There were no reoperations for bleeding. One patient (0.9%) presented a sternal wound infection. Mean follow-up was 18 +/- 7 months. Six patients died during the follow-up and the survival rate was 91%. Ninety-five patients (91%) were symptom-free, 9 patients had a recurrent angina. Postoperative coronary angiography was performed in 11 patients (10%).(ABSTRACT TRUNCATED AT 250 WORDS)

A 58-year-old man underwent simultaneous surgery for WPW syndrome complicated by frequent attacks of atrial tachyarrhythmia combined with angina pectoris persisting after anterior myocardial infarction. Repeated PTCA of 3 times failed and restenosis occurred with recurrent angina particularly when atrial tachyarrhythmia took place. The preoperative ECG suggested the presence of a left free wall accessory pathway confirmed by an electro-physiolosical study. Coronary bypass grafting (LITA-LAD, SVG-4 PD) and division with cryoalation of the accessory pathway were performed using a transseptal left atrial approach. The patient is doing well now and free from both angina and tachycardia.

A 47-year-old man with sever angina pectoris was referred for surgery. Preoperative coronary angiogram revealed giant multiple aneurysms of RCA (Seg 1-Seg 3) and LCX (Seg 11) and LAD (Seg 6). Stenoses were found distal to aneurysm, 90% in RCA-Seg 4, CX-Seg 11, 100% in LAD- Seg 6 and DX-Seg 9 and OM-Seg 12, with collaterals from RCA to LAD. Left ventlicle contracted poorly with the EF of 36 due to anteroseptal infarction. Coronary artery bypass grafting were performed to LAD using a LITA, to DX and LCX using a SVG in the sequential fashion. Postoperative coronary cineangiogram demonstrated that all grafts were patent and multiple giant coronary aneurysms resembled coronary arterial changes of Kawasaki's disease.

A 52-year-old man with reduced left ventricular function (ejection fraction 0.27) due to myocardial infarction, underwent coronary artery bypass grafting (CABG; LITA-LAD, free RITA-4PD) for angina pectoris. He had suffered from recurrent sustained ventricular tachycardia (VT) since 5 hours after CABG. This arrhythmia was resistant to various antiarrhythmic agents such as Lidocaine, Mexiletine, Disopyramide, Procainamide and Propafenone. He required mechanical circulatory supports (intra-aortic balloon pumping and percutaneous cardiopulmonary support) for the maintenance of hemodynamics during repeated VT that required cardioversions of a total of 441 times during 18 days. Following the administration of Amiodarone, the VT was successfully suppressed. However, he had repeated episodes of VT on exercise, thus, he underwent insertion of the implantable cardioverter-defibrillator at the 98 post-operative day, and he was successfully discharged at the 134 post-operative day after CABG. The instrument was verified to be normal in function after the VT induction test.

To determine the operative outcome of coronary artery bypass graft surgery (CABG) for severe coronary artery disease in long-term hemodialysis patients, we analyzed a group of 16 patients who underwent CABG over a ten-year period in our institution. Hospital mortality was 12.5% (2 of 16 patients). These two patients died of ischemic colitis and perioperative myocardial infarction, respectively. There were five late deaths: one patient died from myocardial infarction, one from uremia, one from gastro-intestinal bleeding, one from gastric cancer and one from unknown cause. There were four significant postoperative complications (morbidity 25%), consisted of one pulmonary tuberculosis, one sternal dehiscence secondary to mediastinitis, one mediastinal hematoma secondary to late bleeding from the LITA dissection area and one A-V shunt trouble. Graft patency rate within the first two months was 93% (30 to 42 in 13 patients). Hospital survivors experienced complete relief from angina. Actuarial survival was 68.8% at 3 years, 57.3% at 5 years and 28.6% at 7 years. This rate is not significantly different from the survival of all dialysis patients, but seems to be better than that of dialysis patients with not operated coronary artery disease. We concluded that CABG in dialysis patients can be accomplished with acceptable morbidity and mortality and effective relief of symptoms.
