The results of surgery in 21 patients with I.H.S.S. are reported. Dyspnea, angina pectoris and syncope were the most common symptoms in decreasing frequency. Before the operation, 5 patients were in New York Heart Association's functional class II, 10 in class III and 6 in class IV. The mean resting peak systolic pressure gradient was 66 mm Hg in 20 patients and mean left ventricular end-diastolic pressure was 14 mm Hg in 19 patients. The ventriculoseptomyectomy accomplished through a transaortic approach is the procedure of choice. The operative mortality rate was 14% (3 of 21 patients). There were 2 late deaths from congestive heart failure. Any sudden death did not occur. The remaining 16 patients have been followed up for a mean of 75 months (range 12 months to 11 years), 11 patients are in functional class I, 4 in class II and 1 in class III. Complete left-bundle-branch block occurred in 3 patients. Our study with a long post-operative follow-up period, documents that surgery results in good to excellent alleviation of symptoms in survivors. The elevated pre-operative left ventricular end-diastolic pressure has a significantly poor prognosis. We currently recommend surgery for the symptomatic patients who have not responded to medical therapy, not late in the symptomatic course of the disease.

Of 123 patients with identical clinical criteria for preinfarction angina, 35 were treated medically and 88 surgically in a nonrandomized manner. There was no statistical difference between these two therapeutic groups in regard to age range, average age, sex distribution, number and distribution of prior myocardial infarction, and duration of chronic and acute anginal symptoms. With medical therapy, 32 sustained a myocardial infarction, and 14 (40 per cent) of these died within 1 month of hospital admission. Thirteen of 21 survivors or 37 per cent of the original group are asmptomatic on continuing medical therapy an average of 15 months after discharge. The surgical patients were studied by catherization and anigiography and underwent an early operation. Eight (9.4 per cent) demonstrated evidence of postoperative infarction, and 3 (3.4 per cent) died after the operation. Seventy-one (84 per cent) are completely asymptomatic and 6 are less symptomatic an average of 17 months after the operation. Actuarial analysis of the follow-up data reveals that the initial significant difference in survival between the two groups is maintained through the first 36 months. On the basis of this experience, we suggest that surgical intervention is the therapy of choice in patients with preinfarction angina.

In the past 4 years, among 260 patients receiving coronary bypass grafts for coronary artery disease and stable angina pectoris, there were 34 women (13 per cent). The operative mortality rate for women was 8 per cent (3 of 34), and one late death due to myocardial infarction occurred in spite of a patent coronary bypass graft. The intraoperative infarction rate was 20 per cent (6 per cent in men). Although preoperative cardiac pump and muscle function parameters were better in women than in men (p less than 0.05), postoperatively only 30 per cent of women showed improvement in function as compared with 50 per cent of men. At 6 to 46 months' follow-up, 84 per cent of women were free of angina in contrast with 94 per cent of men. The early (4 month) graft patency rate was 50 per cent (14 of 27 grafts), as opposed to 80 per cent (20 of 25 grafts) in men. These results indicate that, although coronary artery disease shows anatomic similarity in women and men, the result of coronary revascularization in women is inferior to that in the male population.

Late stenosis is a rare but potentially lethal complication of coronary perfusion. In 3 patients, anginal pain appeared 2 to 6 months after aortic valve surgery. Coronary angiography was performed because of rapid evolution of symptoms. Severe stenosis of the common left coronary artery was shown in all 3 cases. Immediate aorto-coronary bypass was undertaken with good results. Graft patency was demonstrated in 2 cases, 6 and 7 months after the operations.

A 26-year-old Japanese man was treated for a transmural myocardial infarct caused by multiple aneurysms of the left main (LMC), left anterior descending (LAD), and the right coronary arteries (RCA). He underwent successful double aorta-coronary saphenous vein bypass grafting. The etiology of the aneurysm remains uncertain but an inflammatory origin is most probable. Review of the literature has indicated that this is the seventh case of coronary artery aneurysms without arteriovenous fistulas to be managed by grafting techniques with the saphenous vein. This experience has suggested that young patients presenting with anginal pain or myocardial infarction whould be carefully examined for coronary artery aneurysms. Since most of the patients developed myocardial infarction probably from thrombotic occlusion or embolism of the distal vessel, this lesion should be considered for surgery whenever anatomically feasible. Coronary artery reconstruction by grafting techniques, with or without resection of the aneurysm, is the treatment of choice. Although surgical treatment has provided good clinical amelioration to our patient as well as the patients previoulsy reported, a careful long-term follow-up should be continued for patients with multiple coronary artery aneurysms of doubtful origin.

Survival in patients with ischemic heart disease is closely related to the extent of coronary artery obstruction as determined angiographically. One hundred forty-nine consecutive patients underwent coronary artery bypass surgery from November, 1971, to October, 1974. There were 2 late cardiac deaths, 1 late noncardiac death, and 1 hospital death, an operative mortality rate of 0.7 per cent and a total mortality rate of 2.7 per cent. Coronary angiograms were scored according to the method of Friesinger, Page, and Ross. Fifty-four per cent (80/149) had scores of 10 or greater. Cumulative survival was analyzed according to life-table techniques; in the 80 surgically managed patients with scores of 10 or greater, survival at 3 years was 98 per cent. Friesinger's 47 nonoperated patients with similar angiographic scores had a 3 year cumulative survival of 68 per cent. Although this study compares different groups, the surgical series was composed of older patients (mean age 52 as compared to 44 years), includes 22 patients operated on urgently for preinfarction angina pectoris, and includes 18 patients with abnormal ventricular function. These data suggest that coronary artery bypass surgery can favorably influence prognosis in patients with severe coronary artery disease.

Forty-four adult patients with isolated aortic valve disease underwent coronary arteriography. Seventy precent of patients required aortic valve replacement (AVR). Of 28 men who underwent AVR, 59 percent of those with severe aortic stenosis, 33 percent of those with severe aortic regurgitation and 50 percent of those with mixed aortic stenosis/aortic regurgitation had associated coronary artery disease. Thirty-six percent of men with aortic valve disease not requiring AVR had significant coronary artery disease (CAD). CAD was not found in the 5 female patients studied. In the patients with CAD, the left anterior descending artery was involved 84 percent of the time. Next in frequency were the right coronary artery, the proximal left circumflex artery, and the obtuse marginal artery. Multivessel disease was the rule. All but one patient with significant CAD had angina pectoris, but many patients with angina had normal coronary arteries. The frequent occurence of significant CAD in adult male patients with isolated aortic valve disease argues for the performance of selective coronary arteriography in all such patients in whom AVR is a consideration.

Between December 1970 and October 1973, 74 patients underwent emergency myocardial revascularization for the relief of acute coronary insufficiency. Through our experience in this area, we have established three categories for which we perform emergency surgery. The first of these is cardiogenic shock complicating acute myocardial infarction for which 14 patients underwent emergency saphenous vein grafting. Seven of these patients expired during operation and one died three months after operation. The second category is acute unstable myocardial infarction for which 25 patients received surgery. There were no operative deaths in this group, but two patients died at six weeks and four months after operation. Thrity-five patients were classified as pre-infarctional angina, the third category for which we perform surgery on an emergency basis. There was one operative death and two late deaths at four and ten months in this group of patients. Our experience suggests that immediate coronary angiography and revascularization will improve survival in the three above-named categories.

In a series of 4,522 consecutive patients who underwent aorta-coronary bypass (ACB) with the saphenous vein at the Texas Heart Institute, 32 had a second revascularization procedure. All patients were reoperated upon because of recurrence of incapacitating angina. Reappearance of angina was related to obstruction of the grafts alone in 6 patients, to the disease of other arteries alone in 16, and to both sources in the remaining 10 patients. In 9 patients progression of the native coronary disease was found, in 16 significant coronary obstructions had been left unbypassed at the time of initial operation, and in the remaining 7 patients inadequate indication and/or performance of revascularization was considered responsible for the failure. Of the 31 survivors, 61 per cent experienced complete relief of angina or were improved, whereas 39 per cent were unimproved. Reoperation was more successful in relieving angina when performed in patients with new lesions or with previously unbypassed lisions than when done in patients with graft occlusion. Incidence of myocardial infarction after the first and second procedure was similar (3 per cent). Reoperation was performed with a mortality rate of 3 per cent, comparable to that of the original procedure, but relief of angina was not achieved so consistently.

An aneurysm of the left sinus of Valsalva compressed the left main coronary artery and the patient experienced anginal pain. Surgical correction consisted of obliteration of the orifice of the aneurysm, aortic valve replacement, and a saphenous vein bypass from the ascending aorta to the distal left anterior descending coronary artery. Postoperative studies revealed excellent function of the prosthetic valve, no recurrence of the aneurysm and retrograde filling of the left anterior descending and circumflex coronary arteries. Three years after the operation, the patient is asymptomatic.
