A 33-year-old man underwent coronary artery bypass graft surgery for relief of angina pectoris. His postoperative course was complicated by hemorrhage and mediastinitis. Death, which occurred after severe hemorrhage from the operative site, was shown at autopsy to be caused by dehiscence of the proximal anastomosis of the right coronary artery graft. The same graft also had a mycotic aneurysm in its midportion. Graft disruption thus appears to be a potential complication of mediastinal infection in patients with saphenous vein bypass grafts.

Internal mammary artery (IMA) bypass to the anterior descending coronary artery (ADA) was performed in 5125 patients from January 1978 to December 1990. The average age of patients was 68 years; males accounted for 68% (3485 patients) and 82% (4203) were NYHA Class III. Left ventricular function was impaired (ejection fraction < 40%) in 68% (3485 patients). The average number of additional saphenous vein graft (SVG) per patient was 2.2. Operative mortality was 1.8%. Mediastinitis occurred in 51 patients (1.0%). Reoperation for bleeding was necessary in 56 patients (1.1%). Perioperative myocardial infarction was seen in 102 patients (2.0%) and neurological complications occurred in 51 patients (1%). Repeat coronary angiography was performed in 1414 patients (28%) and demonstrated a patency rate of 96% in IMA grafts and 75% in SVG grafts (p < 0.001). Survival at 13 years was 80% from all causes and 90% when non-cardiac deaths were excluded. Recurrence of angina occurred in 768 patients (15%) and reoperation or PTCA was performed in 61 (1.2%). During the same time period, 2345 patients underwent coronary artery bypass utilizing solely SVG. Survival at 13 years was 68% from all causes and 78% when non-cardiac deaths were excluded (p < 0.001). Recurrent angina was present in 727 patients (31%) (< 0.001). This data suggests that long-term probability of cumulative survival and occlusion free survival were significantly greater and the probability of recurrent angina and reoperative CABG and death from cardiac causes were significantly less in the IMA patients and should be the conduit of choice in coronary bypass surgery.

From 1985 to november 1989, 270 patients underwent sequential anastomosis with left internal mammary artery (LIMA) on left descending artery (LDA) and diagnonal artery (DA). The first 120 cases have 100% one year follow-up. The perioperative status was: angina stage III or IV: 59%; myocardial infarction (MI): 45%, stenosis of 3 vessels: 52.5%; stenosis of main coronary artery: 10.8%. 2.25 anastomoses were performed per patient. Side-to-side anastomosis (kissing) were not diamond anastomoses but axial and longitudinal. The use of fibrin gllude provides regular curves of the graft between anastomosis. Mortality was 0.8%, morbidity was: MI: 4.2% (2 small infarcts in anterior vessels, 3 others in non-grafted vessels); mediastinitis: 1%; severe bleeding (reoperation): 1%. At one year 93% of patients are free from angina and 71 patients underwent angiographic assessment (145 LIMA anastomosis). Results are as follow: side-to-side anastomosis patency: 98.5%; distal anastomosis obliteration: 3%; LDA anastomosis patency: 95.7% overall sequential anastomosis patency: 97.6%. These results have led our cardiologist in Brest to naturally prefer a surgical approach than percutaneous angioplasty when LDA and DA are involved.

In the two year period from 1989 to 1990, 22 patients (18 men, 4 women; age range from 40 to 59 years) underwent coronary artery bypass grafting (CABG) using in situ and free internal thoracic arteries (ITAs). 23 of total 38 ITA grafts were free grafts in the aorta-coronary position, mainly to provide sufficient graft length. All of 34 ITA grafts were patent in 20 patients with coronary arteriography about one month after operation. There were no early and late death, and all patients were free from angina after a 9.4 month mean follow-up. Perioperative complications included reoperation for the bleeding in one case and the elevation of left diaphragm in one case, but there was no other major complication such as perioperative myocardial infarction, cerebral infarction or mediastinitis. These results indicated that the free ITA could be applied as well as the in situ ITA in multiple CABG of the Japanese with good patency rate and low operative risk.

Fifty-two patients with a mean age of 67.6 years underwent coronary artery bypass plus mitral valve replacement from 2 April 1984, through 6 February 1989. All but four of these 25 males and 27 females were in the New York Heart Association Functional Classes III and IV, with presenting symptoms of angina and/or dyspnea. Twenty-four patients (44.2%) presented with acute myocardial infarctions, and eleven patients (21.2%) had a past history of rheumatic fever or rheumatic heart disease. Forty-five patients (86.5%) had a diagnosis of coronary artery disease plus mitral regurgitation. Treatment included a mean of 2.3 bypass grafts per patient plus mitral valve replacement with Carpentier-Edwards (41), St. Jude (10), and Bjork-Shiley (1) prostheses. The four operative deaths (7.7%) were attributed to congestive heart failure (1), mediastinal bleeding (1), mediastinitis (1), and stroke (1). There were eight late cardiac deaths (16.7%) and six late noncardiac deaths (12.5%), a mean of 16.6 and 18.9 months postoperatively, respectively. Thirty-four patients have survived from 10 to 65 (mean 33.7) months postoperatively with a mean New York Heart Association Functional Class 1.6. Follow-up determination of patients' attitudes toward their surgery was ascertained in 28 of the 34 survivors, and 26 (92.8%) patients indicated that they were pleased with their surgery. These results compare favorably with data reported in the recent literature. In addition, the study shows that patients requiring supportive treatment in a critical care unit preoperatively had the same operative mortality but more postoperative complications and a longer mean hospital stay than the equal number of patients who were not in a critical care unit preoperatively.(ABSTRACT TRUNCATED AT 250 WORDS)

Internal mammary artery bypass (IMA) to the anterior descending coronary artery was performed in 2900 patients from January 1978 to December 1987. The average age of the patients was 64 years. Males accounted for 68% (1972 patients) and 82% (2378 patients) were in New York Heart Association (NYHA) class III. Left ventricular function was impaired in 51%. The average number of additional saphenous vein grafts per patient was 1.8. The operative mortality was 1.6%. Mediastinitis occurred in 29 patients (1%). Reoperation for bleeding was necessary in 32 patients (1.1%). Perioperative myocardial infarction (MI) was seen in 58 patients (2%) and neurological complications occurred in 32 patients (1.1%). Repeat coronary angiography was performed in 703 patients (25%) and demonstrated a patency rate of 96% in IMA grafts and 81% in saphenous vein grafts (SVG). Survival at 9 years was 90% from all causes and 95% when noncardiac deaths were excluded. Recurrence of angina occurred in 522 patients (18%) and reoperation was performed in 15 patients (0.5%). During the same time period, 1783 patients underwent coronary artery bypass utilizing a SVG. Survival at 9 years was 78% from all causes and 83% when noncardiac deaths were excluded. Recurrent angina was present in 546 patients (39%). These data suggest that a patent-IMA to the anterior descending protects against recurrent angina and death from cardiac causes and should be the conduit of choice.

Ninety-four patients 70 years of age and older underwent coronary artery bypass grafting (CABG) between 1979 and 1985. Thirty-two percent were females. An internal mammary artery was used in 49% and concomitant cardiac procedures were performed in 51% of the operations. Early mortality was 12%. Five of 11 early deaths were from non-cardiac causes: ascending aortic disease (2), cerebral damage (2) and septicaemia (1). Postoperative morbidity included neurological complications in 16%, reoperation for bleeding in 12%, mediastinitis or sternal dehiscence in 4% and perioperative acute myocardial infarction in 4%. At follow-up, a median of 2.5 years after surgery, 83% were completely free from angina, 5% much improved, 9% improved and 3% had unchanged symptoms of angina. Actuarial survival, inclusive of early mortality, was 84% at 3 years. Female sex and concomitant cardiac surgery were common in elderly patients who had CABG. Early mortality from noncardiac causes and postoperative morbidity were increased but dramatic relief of symptoms was achieved in the majority of survivors.

Cardiac disease continues to be a major cause of death in patients undergoing long-term hemodialysis. The results of coronary artery bypass grafting (CABG) for severe coronary artery disease in long-term hemodialysis patients have been studied in a group of 12 patients who underwent CABG between January 1979 and December 1983. Hospital mortality was 8% (1 of 12 patients). This patient died of ventricular arrhythmia. Two late deaths occurred, 1 from peritonitis in a patient undergoing long-term peritoneal hemodialysis and 1 from metastatic renal cell carcinoma. The two postoperative complications (morbidity 17%) consisted of a sternal dehiscence secondary to mediastinitis and a perioperative cerebrovascular accident. Ten of the 11 hospital survivors experienced complete relief from angina. In the other patient the angina became easier to control with medication. Combining this series of patients with those previously reported in the literature allows determination of actuarial survival in a group of 25 patients followed up for 1 to 79 months (mean, 33 months). Actuarial survival was 83% at one year, 69% at three years, and 48% at five years. This is not significantly different from the survival of long-term hemodialysis patients who have coronary disease but have not undergone CABG. It appears that CABG, when performed in long-term hemodialysis patients, is associated with an only slightly greater risk of mortality and morbidity than CABG performed in routine patients. Although CABG provides considerable symptomatic relief of angina, no statistically significant change in actuarial survival can be demonstrated.

This case illustrates the previously unreported combination of severe fibrosing mediastinitis involving the entire intrapericardial aorta, pulmonary artery, and innominate artery in a patient requiring coronary revascularization for chronic angina and multivessel coronary artery disease. Due to the mediastinal fibrosis, normal revascularization procedures and myocardial preservation techniques were altered and are described.

The performance of open heart surgery in a patient with a tracheostoma can present difficult problems, including postoperative mediastinitis and inadequate operative exposure. Recently, we experienced two cases in which tracheostomy had been done preoperatively due to heart failure and reported the satisfactory results in this paper. Case 1; A 59-year-old woman who had mitral stenosis and massive regurgitation received mitral valve replacement and left atrial raphy. The approach to heart was performed in according to the following. A transverse submammary skin incision was made from right anterior axillar line to left mammary line and then a bilateral thoracotomy was made at the fourth intercostal space. Case 2; A 73-year-old man who had old myocardial infarction and postinfarction angina received coronary artery bypassgrafting to right coronary artery and left anterior descending branch, using saphenous vein grafts. A skin incision was placed at the second intercostal space in the fashion of "collar skin incision" and then made from the center of collar skin incision to the xiphoid process. The sternum was transected at the second intercostal space and divided longitudinally to the xiphoid process. These two approaches provided the adequate operative field. The cannulation of the ascending aorta, the superior vena cava and the inferior vena cava presented no difficulty and the operative procedure could be performed easily in a routine manner. We think that in a case of open heart surgery of a patient with a tracheostoma the approach in which the skin incision is distant from the area of a tracheostoma and no dissection near a tracheostoma is necessary have to be selected in order to decrease the risk of postoperative wound infection and mediastinitis.
