Abstract
INTRODUCTION AND OBJECTIVES To evaluate the prevalence, clinical characteristics, and outcomes of patients with angina undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis. METHODS A total of 1687 consecutive patients with severe aortic stenosis undergoing TAVR at our center were included and classified according to patient-reported angina symptoms prior to the TAVR procedure. Baseline, procedural and follow-up data were collected in a dedicated database. RESULTS A total of 497 patients (29%) had angina prior to the TAVR procedure. Patients with angina at baseline showed a worse New York Heart Association (NYHA) functional class (NYHA class> II: 69% vs 63%; P=.017), a higher rate of coronary artery disease (74% vs 56%; P <.001), and a lower rate of complete revascularization (70% vs 79%; P <.001). Angina at baseline had no impact on all-cause mortality (HR, 1.02; 95%CI, 0.71-1.48; P=.898) and cardiovascular mortality (HR, 1.2; 95%CI, 0.69-2.11; P=.517) at 1 year. However, persistent angina at 30 days post-TAVR was associated with increased all-cause mortality (HR, 4.86; 95%CI, 1.71-13.8; P=.003) and cardiovascular mortality (HR, 20.7; 95%CI, 3.50-122.6; P=.001) at 1-year follow-up. CONCLUSIONS More than one-fourth of patients with severe aortic stenosis undergoing TAVR had angina prior to the procedure. Angina at baseline did not appear to be a sign of a more advanced valvular disease and had no prognostic impact; however, persistent angina at 30 days post-TAVR was associated with worse clinical outcomes.

Abstract
In a preoperative evaluation, 35 consecutive patients with aortic stenosis were examined by means of exercise ECG, Doppler and direct manometric measurements of the pressure difference over the aortic valve (delta P) and angiocardiography. Coronary artery disease (CAD) was found in 43% of the patients. Those with CAD had a lower mean maximum physical performance expressed as a percentage of the normal value (Wmax%), larger ST depressions and a higher effort angina (EA) score at the exercise test than the non-CAD group. Mean delta P was equal in the two groups. A myocardial coronary obstruction score covariated positively with a coronary insufficiency index (CT index = 100 X STdepr/Wmax%) and the EA score. There was no correlation between delta P and the EA score or the CI index. A CI index less than 3 and an EA score less than 2 were found in 49% of the patients and excluded the presence of CAD with a predictive accuracy of 88%, a better diagnostic complement to coronary arteriography than a history of EA.

Abstract
BACKGROUND Angina pectoris has long been recognised as one of the principal symptoms of severe aortic valve stenosis (AS), even in patients without significant coronary artery disease (CAD). However, controversy exists concerning the prevalence of angina pectoris and associated CAD in such patients. OBJECTIVE To determine the prevalence of CAD detectable by angiography and its relation to angina pectoris and coronary risk factors in patients with severe AS. PATIENTS AND METHODS All patients with symptomatic AS who had undergone aortic valve replacement and preoperative cardiac catheterisation at the Austin and Repatriation Medical Centre between 1 January 1986 and 31 May 1996 were retrospectively analysed. Those patients with multiple valve disease, aortic regurgitation of grade 2 or more in severity, or who had had prior coronary artery or valve surgery were excluded from this analysis. RESULTS A total of 328 consecutive patients with severe AS (242 men and 86 women; mean age 72 years, range 39-84 years) were studied. Significant CAD (reduction in luminal diameter > or = 50%) was found in 162 patients (49.4%). Typical angina was present in 74.7% of these 162 patients but it was also found in 44.6% of the 166 patients without obstructive CAD. Of the patients without angina (n = 133), 30.8% had significant CAD. By multivariate logistic regression, we have identified seven significant predictors for CAD among severe AS patients. Five factors increased risk. Expressed as odds ratio with 95% confidence interval, these included: (i) age in years (1.07; 1.04-1.11, P = 0.001); (ii) male gender (2.09; 1.14-3.80, P = 0.016); (iii) angina pectoris (3.19; 1.89-5.37, P < 0.001); (iv) history of myocardial infarction (2.87; 1.38-5.97, P = 0.005); and (v) peripheral vascular disease (2.28; 1.28-4.05, P = 0.005). Factors associated with decreased likelihood of CAD were serum high density lipoprotein (HDL) cholesterol (0.58; 0.34-0.71, P = 0.002) and peak systolic gradient across the aortic valve (0.97; 0.95-0.99, P = 0.0113). CONCLUSION Coronary arteriography can probably be omitted for a patient with severe AS if that patient has no symptoms of angina and has no risk factors known to increase its incidence.

Abstract
Exposure for aortic valve operations after previous coronary artery bypass grafting may be technically difficult owing to the presence of patent vein grafts on the proximal aorta. A patch or "island" aortotomy technique that allows excellent exposure of the aortic valve is presented here. In select patients this approach may facilitate cardioplegia administration.

Abstract
Early and late outcome was studied in 630 patients who underwent aortic valve replacement between 1974 and 1982. Group 1 (506 patients) did not have important coronary artery disease, group 2 (69 patients) had coronary artery disease and underwent coronary artery bypass grafting, and group 3 (55 patients) had coronary artery disease but did not undergo myocardial revascularisation. Early mortality (within 30 days of operation) was significantly lower for group 1 (6%) than for group 2 (13%) and for group 3 (16%). Operative mortality in all three groups was lower in patients operated on more recently. The three year survival of patients in group 1 (83%) was significantly higher than that of patients in group 3 (62%) but not than that of patients in group 2 (76%). The findings of this study suggest that the presence of coronary artery disease increases the risk of aortic valve replacement whether or not coronary artery grafting is performed. Myocardial revascularisation, however, seems to return patients with aortic valve and coronary artery disease to a survival curve similar to that of patients with isolated aortic valve disease.

Abstract
A consecutive series of 192 patients (121 men and 71 women, mean age 59 years, range 28 to 82) with isolated, severe valvular aortic stenosis was with isolated, severe valvular aortic stenosis was analyzed retrospectively to determine the relation of angina pectoris and coronary risk factors to angiographically significant coronary artery disease (CAD). Significant CAD (diameter reduction greater than or equal to 50%) was found in 47 patients (24%). Angina was present in 83% of them, but it was also found in 61% of the non-CAD patients. This symptom had as a result a low positive predictive value (31%). Of the patients without angina (n = 65) 12% had significant CAD. The negative predictive value of angina alone was thus 88%. By using multivariate logistic regression, a risk score could be calculated based on angina, age and sex, which increased the negative predictive value to 95%. It was concluded that coronary arteriography can only be omitted in severe aortic valvular stenosis, when patients have no angina and when they are less than 40 years of age for men and less than 50 years for women. For all other cases, coronary arteriography should be recommended.

Abstract
A consecutive series of 198 patients (148 men and 50 women, mean age 51 years, range 18 to 76) with pure, isolated, severe aortic regurgitation was retrospectively studied to determine the prevalence of angiographically significant coronary artery disease (CAD) and its relation to angina pectoris and coronary risk factors. Significant CAD (coronary diameter stenoses greater than 50%) was found in 28 patients (14%). Typical angina was present in 18% and atypical chest pain in 16%. Angina alone had a sensitivity of 57% to detect significant CAD. The predictive accuracy of a positive history of angina was 46% and that of a negative test 93%. By using multivariate logistic regression, a risk score could be calculated that increased the sensitivity to 74% at equal specificity. Almost 40% of the total population had a risk score of less than -2.9 (only 1 patient in this group had CAD). It is concluded that coronary arteriography can safely be omitted in many patients with severe aortic regurgitation if they have no symptoms of myocardial ischemia or risk factors known to increase its incidence.

Abstract
Data from 1,156 patients greater than or equal to 30 years of age who underwent aortic valve replacement alone or with coronary artery bypass grafting from 1967 through 1976 (early series) and 227 similar patients operated on during 1982 and 1983 (late series) were reviewed. In the early series, 414 patients (36%) had preoperative coronary arteriography (group 1): group 1A (n = 224) did not have coronary artery disease, group 1B (n = 78) had coronary artery disease but did not undergo bypass grafting and group 1C (n = 112) had coronary artery disease and underwent bypass grafting. The 742 patients in group 2 did not have preoperative arteriography. Operative mortality rates (30 day) in groups 1A, 1B, 1C and 2 were 4.5, 10.3, 6.3 and 6.3%, respectively (p = NS). The 10 year survival in both groups 1 and 2 was 54%; in groups 1A, 1B and 1C it was 63, 36 and 49%, respectively (1A and 1B, p less than 0.01). In the late series, the 227 patients were divided into similar groups (group 1A, n = 73; 1B, n = 32; 1C, n = 99), and 90% had preoperative coronary arteriography. Operative mortality rates (30 day) for groups 1A, 1B and 1C were 1.4, 9.4 and 4.0%, respectively; that for group 2 (no preoperative arteriography, n = 23) was 4.3%. Definition of coronary anatomy by angiography seems important in most patients greater than or equal to 50 years old who are candidates for aortic valve replacement, and bypass grafting is recommended for those with significant coronary artery disease.

Abstract
Among 646 patients with pure aortic stenosis who underwent valve replacement at our institution between 1981 and 1985, the three most frequent causes were calcification of congenitally bicuspid aortic valves (38%), degenerative (senile) calcification of tricuspid aortic valves (33%), and postinflammatory (presumably rheumatic) calcification and fibrosis (24%). Among the 324 patients younger than 70 years of age, calcified bicuspid valves were observed in 50%. In contrast, among 322 patients 70 years of age or older, degenerative calcification accounted for 48% of the stenotic aortic valves. During the 5 years of the study, the relative frequency of postinflammatory disease decreased from 30% to 18%, and that of bicuspid valves decreased from 37% to 33%. In contrast, the relative frequency of degenerative calcification increased from 30% to 46%. Consequently, degenerative (senile) calcification is currently the most common cause of aortic stenosis among patients undergoing valve replacement at our institution. This finding may be related to changes in life expectancy in the general population, alterations in patient referral practices, and an increased willingness of surgeons to operate on older patients. Regardless of cause, the observed temporal changes in etiologic factors for aortic stenosis may indicate a potential source of increasing health-care costs among the elderly population.

Abstract
Ninety-six consecutive patients older than 40 years with severe mitral stenosis were retrospectively analyzed to determine the relation of angina pectoris (AP) and coexistent coronary artery disease (CAD). Of the 96 patients, 27 (28%) had angiographically significant CAD, 10 (37%) with AP and 17 (63%) without AP. Of the 96 patients, 21 had AP, 10 (48%) with angiographically significant CAD and 11 (52%) without (CAD). Of 75 patients without AP, 17 (23%) had angiographically significant CAD AP had a specificity of 84% and a sensitivity of 37% in its ability to detect significant CAD. The pulmonary artery systolic, diastolic and mean pressures and the pulmonary vascular resistance did not differ between patients with and those without AP (p greater than 0.05). It is concluded that coexistent CAD is commonly found in patients older than age 40 with severe MS, and is usually clinically silent.

Abstract
Seventy-eight patients with isolated, severe aortic regurgitation (AR) were studied retrospectively to determine the prevalence of angiographically significant coronary artery disease (CAD) and its relation to angina pectoris (AP). Angiographically, significant CAD was present in 29 of 78 patients (37%), and 36 patients (46%) had AP. Twenty-one of 36 patients (58%) with AP and 8 of 42 patients (19%) without AP had angiographically significant CAD. AP as a predictor of significant CAD had a sensitivity of 73%, specificity of 69% and a risk ratio of 3:1. The predictive accuracy of detecting CAD in the absence of AP was 81%. The benefit from concomitant coronary artery bypass grafting at the time of aortic valve replacement for AR has not been clearly demonstrated; therefore, routine coronary angiography is still recommended for all AR patients older than 40 years undergoing aortic valve replacement.

Abstract
One hundred three patients with isolated, severe aortic stenosis (AS) were retrospectively analyzed to determine the relation of angina pectoris to angiographically significant coronary artery disease (CAD). All patients underwent coronary angiography regardless of the presence or absence of angina. Angina was significantly associated with CAD (p less than 0.002), with a sensitivity of 78% and a specificity of 53%. However, 25% of the patients without angina had angiographically significant CAD, and in these patients there was a 70% prevalence of 1-vessel disease. Patients with isolated, severe AS should undergo coronary angiography to identify coexistent CAD accurately. The absence of angina does not reliably exclude angiographically significant CAD.

Abstract
The incremental risk of coronary bypass surgery was analyzed in 718 patients undergoing mitral valve replacement between 1971 and 1983. Ninety-eight patients (14%) had significant coronary artery disease requiring coronary bypass surgery. In 70 of these patients, the origin of the mitral valve disease was nonischemic, whereas 28 patients had ischemic mitral regurgitation unsuitable for conservative valve surgery. There were six operative deaths (9%) and four perioperative myocardial infarctions (6%) after mitral valve replacement and coronary bypass surgery for nonischemic mitral valve disease. Operative mortality was related to low output cardiac failure before operation or perioperative myocardial infarction. Actuarial curves predict survival (+/- standard error) of 55 +/- 7% at 5 years and 43 +/- 8% at 10 years. Preoperative functional class was the only significant predictor of long-term survival in this group (p less than 0.05). The actuarial survival of the 620 patients without coronary artery disease who underwent mitral valve replacement alone was 63 +/- 3% at 10 years. This was significantly better than that of the 70 patients who underwent mitral valve replacement and coronary bypass surgery for nonischemic mitral valve disease (p less than 0.001). Conversely, 5 year survival of the 28 patients with ischemic mitral regurgitation was 43 +/- 10%. This confirms the negative detrimental effect of an ischemic origin of mitral valve disease on survival after mitral valve replacement and coronary bypass surgery (p less than 0.0001).

Abstract
The prevalence of significant coronary artery disease (reduction in luminal diameter by more than 50%) among 88 consecutive patients with aortic stenosis requiring aortic valve replacement at Hammersmith Hospital was examined. Twenty two (34%) patients had significant coronary disease. Nineteen of 42 (45%) patients with typical angina had coronary disease; three of 20 (15%) patients with atypical chest pain had coronary disease, while none of 26 patients free of chest pain had significant coronary disease. Risk factors for coronary disease were equally distributed among patients with and without significant luminal obstruction. Because of the small, but definite, hazard of coronary arteriography and in the interest of cost containment it is suggested that patients with aortic stenosis who are free of chest pain do not require routine coronary arteriography. This applies particularly to patients requiring urgent aortic valve replacement.

Abstract
In our report, the presence or absence of angina pectoris did not predict the presence of coronary artery disease. A significant number of patients with aortic stenosis and angina pectoris have coronary artery disease but coronary artery disease also exists in asymptomatic form in a significant number of patients with severe aortic stenosis that could not be detected clinically and therefore suggests that the routine use of selective coronary arteriography is indicated in patients over 40 years undergoing cardiac catheterization because of aortic stenosis. This is very important in the preoperative evaluation and in planning the technique of operation to employ during extracorporeal circulation and in determining the necessity of combining aortic valve replacement and myocardial revascularization.

Forty-one patients underwent valve surgery at our institution based solely on clinical, M-mode echocardiographic, phonocardiographic, and external pulse recording findings without preoperative cardiac catheterization. Patients with clinical evidence of coronary artery disease were excluded from the study. Preoperatively, 83% of the patients were New York Heart Association functional class III or IV. In all patients, the noninvasive evaluation was considered sufficiently diagnostic of the nature and severity of valvular heart disease to allow surgery without preoperative catheterization. In 23 of 41 cases (group 1), cardiac catheterization was not performed due to the patients' unstable hemodynamic condition at the time surgery was being considered. In the remaining 18 patients (group 2), the probability of obtaining data at catheterization that would significantly affect management decisions was thought to be low, thus not justifying the cost and potential morbidity of this procedure. In all cases, the noninvasive diagnosis was corroborated at operation; there were no unexpected findings nor deaths related to incomplete or incorrect diagnoses. Over a followup period of 4.5 +/- 1.4 years, no patient experienced signs or symptoms of ischemic heart disease. In selected patients without anginal chest pain syndromes, appropriate and successful valve surgery may be performed on the basis of combined clinical and noninvasive evaluation without the need for cardiac catheterization.

Abstract
Coronary hemodynamic effects of controlled left ventricular outflow obstruction stimulating aortic valve stenosis were studied in 20 open-chest dogs, with and without graded coronary artery diameter narrowing. Aortic stenosis was regulated so that a mean left ventricular-aortic pressure gradient of 46 +/- 20 mm Hg (mean +/- standard deviation) was created as both heart rate and stroke volume were unchanged. In addition, during aortic stenosis, mean aortic pressure (105 +/- 17 to 84 +/- 15 mm Hg, p less than 0.05) and diastolic pressure time index/systolic pressure time index ratio (1.2 +/- 0.3 to 0.6 +/- 0.2, p less than 0.05) decreased and end-diastolic left ventricular pressure (7 +/- 4 to 14 +/- 6 mm Hg, p less than 0.05) increased. With no coronary narrowing, mean coronary flow increased during aortic stenosis (53 +/- 23 to 62 +/- 23 ml/min) as the percentage of diastolic flow increased (83 +/- 6 to 89 +/- 4) and endocardial/epicardial ratio decreased (1.14 +/- 0.16 to 0.95 +/- 0.24) (all p less than 0.05). Peak reactive hyperemic flow also decreased (168 +/- 85 to 125 +/- 73 ml/min, p less than 0.05). This value with no coronary narrowing was similar to peak hyperemic flow with 60% narrowing without aortic stenosis. With 90% coronary narrowing, mean coronary flow decreased with or without aortic stenosis. Transmural flow distribution also decreased but was lower during aortic stenosis (0.86 +/- 0.19 to 0.61 +/- 0.25, respectively; p less than 0.05). These data suggest that although mean coronary flow is increased during aortic stenosis, endocardial flow may be limited, and coronary reserve exposed during reactive hyperemia appears decreased. When a coronary artery is narrowed, aortic stenosis has an even more important hemodynamic influence on the coronary circulation.

Abstract
A prognostic index for predicting significant coronary artery disease was established using multiple logistic regression analysis of clinical data from 643 patients with valvular heart disease who had undergone routine coronary arteriography before valve replacement. The index or equation obtained incorporated the presence of angina, a family history of ischaemic heart disease, age, cigarette smoking habits, mitral valve disease, sex, and electrocardiographic evidence of myocardial infarction. The equation was validated using prospective data from 387 patients with valvular disease and shown to enable almost a third of routine coronary arteriograms to be omitted while maintaining 95% sensitivity for patients with coronary artery disease. Similar analysis of the more detailed prospective data produced a second discriminant function incorporating diastolic blood pressure, total cigarettes smoked in life, the severity of angina, family history of ischaemic heart disease, age, current cigarette smoking habits, and the ratio of total to high density lipoprotein cholesterol. This method improved the discrimination between patients with and without coronary artery disease, allowing omission of 30% of routine coronary arteriograms with 100% sensitivity for patients with coronary disease and omission of 41% with a 96% sensitivity level.

Abstract
To determine the prevalence and significance of exercise-induced localized perfusion defects in symptomatic patients with aortic valve disease, thallium-201 rest and exercise studies were performed in a consecutive series of 29 such patients prior to left heart catheterization with coronary arteriography. Eight patients had repeat studies after aortic valve replacement. Twelve of 17 patients with predominant aortic regurgitation (AR) had distinct LV apical defects during exercise despite normal coronary arteries, while 10 of 12 patients with aortic valve disease and associated coronary artery disease (CAD) had localized perfusion defects in LV areas other than the apex. In patients with AR, reversible apical perfusion defects can occur without CAD; these apical defects are probably a reflection of severe LV volume overload in AR. LV perfusion defects in areas other than the apex are specific for CAD in aortic valve disease, and concomitant CAD may not provoke regional LV perfusion deficits in aortic stenosis patients with severe LV hypertrophy.

Abstract
Eighty-two patients with mitral stenosis underwent cardiac catheterization with coronary angiography. Twenty-one patients (26 percent) had coronary artery disease. Characteristics of the mitral valve area, cardiac output, pulmonary artery pressure, pulmonary vascular resistance, left ventricular end-diastolic pressure, left ventricular ejection fraction, and atypical chest pain did not correlate with findings of angina pectoris or of coronary artery disease; however, there was correlation with sex, age, and angina. Coronary artery disease occurred only after the age of 40 years and was more frequent in males with angina. Coronary artery disease could not be ruled out in patients with mitral stenosis, especially those over age 40, without coronary arteriography.

Abstract
An in-depth statistical analysis of early and late results of aortic valve replacement using the Björk-Shiley tilting-disc prosthesis is presented. Our experience with this prosthesis indicates that replacement carries a low surgical risk, a low incidence of complications (embolization, infection, or hemorrhage due to long-term use of anticoagulants), and good long-term survival. Coexisting coronary artery disease increases surgical mortality significantly, and simultaneous, complete revascularization is essential. Patients undergoing isolated aortic valve replacement did significantly better than those requiring other simultaneous procedures or those who had had previous operations. Earlier operation is imperative since progress of aortic valve disease is unpredictable by duration of symptoms, and patients in New York Heart Association Functional Class II have a low surgical risk and a greatly increased survival. It would appear from this study that additional criteria, such as increasing ventricular dilatation and hypertrophy determined by echocardiographic studies and gated nuclear studies showing deterioration of ejection fraction on exercise, should be used to help determine time of surgical intervention rather than symptomatology alone.

Abstract
Thirty-three patients with aortic valve disease, fifteen with regurgitation, eleven with stenosis and seven with mixed disease, undergoing assessment for valve replacement which included adequate coronary angiography, were studied. A symptom limited graded treadmill exercise test was undertaken with administration of 40-70 MBq of 201Tl. Myocardial imaging was started within 15 minutes and repeated after four hours using a 37 PM tube Searle gamma camera. Myocardial images were read independently by three observed. Of the 33 sets of images, 21 were -ve, 5 +ve, 2 I (Indeterminate) and 5 D (Difference of opinion). Eight of the 33 patients had significant coronary artery disease (CAD) and of these three were scored +ve (all triple vessel). Two patients without CAD were scored +ve. Eight subjects developed angina during exercise testing, of whom four had CAD, and four with CAD did no develop angina. Historically, 13 of the 33 subjects had typical angina, six having CAD; an additional eight had other significant chest pain, two having CAD. In these subjects with severe aortic valve disease, exercise testing and myocardial imaging with 201 TI was of little value in detecting CAD. All patients with CAD gave a history of significant chest pain.

Abstract
The case notes, cardiac catheterisation data, and coronary arteriograms of 239 patients investigated for valvular heart disease during a five year period were reviewed. Angina present in 13 of 95 patients with isolated mitral valve disease, 43 of 90 patients with isolated aortic valve disease, and 18 of 54 patients with combined mitral and aortic valve disease. Significant coronary artery disease was present in 85 per cent of patients with mitral valve disease and angina, but in only 33 per cent of patients with aortic valve disease and angina. Patients with no chest pain still had a high incidence of coronary artery disease, significant coronary obstruction being present in 22 per cent with mitral valve disease, 22 per cent with aortic valve disease, and 11 per cent with combine mitral and aortic valve disease. Several possible clinical markers of coronary artery disease were examined but none was found to be of practical help. There was, however, a significant inverse relation between severity of coronary artery disease and severity of valve disease in patients with aortic valve disease. Asymptomatic coronary artery disease is not uncommon in patients with valvular heart disease and if it is policy to perform coronary artery bypass grafting in such patients, routine coronary arteriography must be part of the preoperative investigation.

Abstract
Experience with aortic valve replacement over a 9-year period is reviewed. Hospital mortality was 5.0%, with an additional late mortality of 15.0% during a mean follow-up period of 4.3 years. There was a 7.5% mortality among the 93 patients who were operated on using direct coronary perfusion. There were no early deaths among the 48 patients operated on using cold cardioplegic arrest. Paravalvular leaks developed in 20 patients, and 9 had reoperation. There were no early deaths following elective reoperations for prosthetic valve dysfunction, but urgent reoperation was associated with a 40% mortality. Eighty percent of all patients are still alive at a maximum follow-up of 9 years. Eighty-six percent of the survivors who were in New York Heart Association Functional Class III or IV before operation are now in Class I or II. Hypothermic cardioplegic arrest was found to be preferable to coronary perfusion as a method of myocardial protection during aortic valve replacement. Patients with paravalvular leaks who have a history of left ventricular failure prior to aortic valve replacement should be considered candidates for early elective reoperation, owing to the significantly greater mortality associated with urgent reoperation.

Abstract
There is widespread agreement that aortocoronary bypass grafting generally lessens the symptoms and functional limitations of patients with angina pectoris. Evidence for prolongation of life or prevention of myocardial infarction, arrhythmias and ventricular dysfunction is inconclusive. Harmful effects associated with surgical management of coronary artery disease can be documented in terms of operative mortality, perioperative myocardial infarction, graft occlusion and progression of occlusive disease in the native circulation. In this review of published experience, the accomplishments and the limitations of myocardial revascularization are considered in various clinical settings. Critical assessment of evolving information leads to the conclusion that widespread application of this procedure beyond the alleviation of symptoms refractory to medical therapy is not justified by present data.

Abstract
The pre-operative clinical and haemodynamic findings of 139 consecutive patients with aortic stenosis were analysed in an attempt to determine the incidence and influence of coronary heart disease on the mode of presentation of patients with aortic stenosis. The overall incidence of coronary heart disease was 32%. 105 patients (76%) presented with angina and of these, 41 patients (39%) had significant coronary heart disease as compared to 4 (13%) of the remaining 34 patients who did not present with angina. Clinical parameters including age, sex, severity of angina together with the presence of associated symptoms and precipitating factors were unhelpful in distinguishing those patients with coronary heart disease. Evidence of previous transmural myocardial infarction or the presence of ST-T abnormalities in the absence of digitalis and the changes of left ventricular hypertrophy were reliable electrocardiographic signs of coronary heart disease. Although peak systolic aortic valve gradient tended to decrease with increasing severity of coronary heart disease, the severity of aortic stenosis was not a reliable indicator of the presence of coronary disease. Patients with coronary heart disease in the absence of angina all had a combination of moderate aortic stenosis and single vessel disease. It is concluded that coronary heart disease cannot be predicted in patients with angina and, in the absence of angina occurs with an incidence sufficiently high to advocate the use of coronary angiography as part of the investigation of all patients with aortic stenosis being considered for valve replacement.

Abstract
Pre-infarction angina, in the absence of coronary artery disease, was found in a 62 year-old man with severe calcific aortic stenosis. After application of intraaortic balloon pump counter-pulsation, the condition was stabilized, and coronary arteriograms were safely carried out. Interestingly, an elevated right atrial and right ventricular end-diastolic pressure with an associated Bernheim's effect was demonstrated by cardiac catheterization. The hemodynamics of the right heart returned to normal after surgical correction of the aortic stenosis. The clinical indications for intra-aortic balloon pump counterpulsation in this setting are discussed.

Abstract
The present review has attempted to summarize the classic symptoms and signs of aortic valve stenosis, especially in an adult. It is emphasized that all the classic signs rarely are present and their absence may mislead an unwary clinician. The diagnostic help provided by noninvasive tests, including echocardiography and phonocardiography, has been emphasized. A need for cardiac catheterization and angiography in most patients prior to corrective surgery is stressed. The natural history of the disease without operative intervention is dim and a significant risk of sudden death exists. The current surgical approach with immediate and long-term results is summarized. Finally, attention has been drawn to the special clinical circumstances when the aortic valve stenosis provides a strinkingly different clinical picture. We cannot find a better way to end this review than by quoting a warning note given by Thomas Lewis in 1920: "It is the faint cry of an anguished and fast failing muscle, which, when it comes, all should strain to hear, for it is not long repeated. A few months, a few years at most, and the end comes."

Abstract
Twenty-six consecutive patients underwent combined aortic valve replacement and myocardial revascularization at the Emory University Affiliated Hospitals between May, 1973 and March, 1976. Acute myocardial infarction resulted in two operative deaths (8%). There have been four late deaths, all Class IV preoperative. The age range was 37 to 79 years with an average age of 60. Preoperatively all patients were Class IV or late Class III. Twenty-three patients had symptoms of angina pectoris; congestive heart failure was evident in 56%. Postoperatively, 70% are now Class 1 or II. Single coronary bypass was performed in 16 patients, double in 6, and triple in three. Double bypass plus mitral valve replacement was required in two with aneurysmectomy in one. The rate of intraoperative infarction was 27% for the series but only 7% in the last year. The methods of intraoperative myocardial preservation and the technical approach for the operative procedures were variable. Results with each method are correlated, and currently preferred techniques are presented and discussed. Best results were obtained in patients who presented early in their symptomatic course with isolated proximal coronary lesions and good renoff vessels. Excellent results could be achieved despite advanced age of patients, requirement for multiple bypass grafts, and correction of other associated cardiac lesions. Poorest results were obtained when long-standing ventricular failure was combined with poor vessels distal to coronary stenoses.

Abstract
In order to relate the frequency of angina pectoris to associated coronary artery disease, 66 consecutive patients with severe aortic valvular disease were studied by cardiac catheterization, including coronary angiography. Angina pectoris was found in 63 per cent of patients with predominant aortic stenosis, 62 per cent with aortic regurgitation, and 67 per cent with mixed disease. Associated coronary artery disease (larger than or equal to 75 per cent luminal stenosis) ranged from 14 to 28 per cent and averaged 20 per cent for the entire group of 66 patients. Only one patient without angina had significant coronary artery stenosis. Our studies indicate that angina pectoris is equally common in all forms of severe aortic valve disease and is usually not associated with significant coronary artery disease.

Abstract
To evaluate the usefulness of routine coronary arteriography in patients undergoing cardiac catheterization for the evaluation of valvular heart disease, we performed coronary arteriographic studies routinely in a series of 201 patients primarily catheterized for such evaluation. Coronary artery obstructive lesions in excess of 50% of the lumen were present in 45 of the 201 patients. In 18 of the 45 there was no history of chest pain. Three of the 18 had three vessels involved while 2 had two vessels involved. A total of 27 patients (13.4%) had luminal obstruction greater than 70%, and 9 of these had no pain. In 35 of the 201 patients, classic angina pectoris existed in the absence of radiographically significant disease. Severe coronary disease was found to coexist with hemodynamically severe valvular heart disease and was not predictable noninvasively.

Abstract
From 1967 through 1973, 80 consecutive patients underwent simultaneous aortic valve replacement (AVR) and coronary bypass grafting. Fourteen (18%) experienced no angina pectoris and had no history or electrocardiographic evidence of coronary atherosclerosis. Seven of these 14 had severe multiple vessel disease. All operations were performed under normothermic conditions without coronary perfusion. Seven patients (9%) died during operation. Intra-operative myocardial infarction was documented in eight (10%). After a mean follow-up of 35 months, overall mortality was highest in aortic regurgitation patients [seven of 13 (54%)] compared to aortic stenosis [17 of 54 (31%)] (P less than 0.07), and mixed pathology [1 of 13 (8%)]. Thirty-one of 34 (91%) grafts in 25 patients were patent an average of 12 months postoperatively. After 42 months a 65% actuarial survival was found in the combined AVR and graft(s) series versus a 76% survival in 300 AVR patients proven by angiography not to have severe coronary atherosclerosis.

Abstract
The safety of combined operative procedures for valvular and coronary artery disease was reviewed in 27 patients. Twelve patients had aortic valve disease and 15 had mitral valve disease. Forty-seven coronary artery reconstructions were performed, and average of 1.7 per patient. Twenty-two patients underwent valve replacement and 5 had valvuloplasty. Congestive heart failure was the major symptom in 20 patients, and angina was the major symptom in 7. Eight of the patients with congestive heart failure had no angina, but significant coronary stenoses were demonstrated at routine coronary angiography. Coronary reconstruction was performed before valve repair. Two patients died postoperatively (a hospital mortality of 7.4%), and there were 4 late deaths from 2 to 28 months postoperatively. There were no postoperative myocardial infarctions. Contrary to previous reports, coronary artery reconstruction and valve repair need not be associated with an increased risk. Protection of the myocardium by coronary perfusion through reconstructed coronary arteries enables valve repair to be done without greater risk than valve repair alone. All patients considered for valve repair should have coronary angiography.

Abstract
To clarify the association between chest pain and significant coronary artery disease in patients who have aortic valve disease, 76 consecutive candidates for aortic valve replacement were evaluated prospectively with use of a historical questionnaire and coronary arteriography. Of the 76 patients, 19 (25 percent) had no chest pain, 21 (28 percent) had chest pain that was not typical of angina pectoris and 36 (47 percent) had chest pain typical of anigina pectoris. In 18 of 19 patients the absence of chest pain correlated with the absence of coronary artery disease. The single patient without chest pain who had coronary artery disease had evidence of an inferior myocardial infarction in the electrocardiogram. Thus, absence of chest pain and the absence of electrocardiographic evidence of infarction predicted the absence of coronary disease in all cases. The presence of chest pain did not predict the presence of coronary artery disease, but the more typical the pain of angina pectoris the more likely were patients to have significant coronary artery disease. Of the 21 patients with atypical chest pain, 6 (29 percent) had coronary artery disease, but of the 36 patients with typical angina pectoris 23 (64 percent) had significant coronary artery disease. In addition, when patients with chest pain not typical of angina pectoris also had coronary artery disease, the diseased vessels usually supplied smaller areas of the left ventricle than when the pain was typical of angina pectoris. In 21 of 23 patients (91 percent) with typical angina pectoris and significant coronary artery disease, lesions were present in the left coronary artery. There was no systolic pressure gradient across the aortic valve that excluded the presence of coronary artery disease, although all patients with a calculated aortic valve area of less than 0.4 cm2 were free of coronary artery disease. Patients with severe left ventricular dysfunction were more likely to have normal coronary arteries.

Abstract
Between July 1, 1971, and March 1, 1975, 45 patients underwent combined valvular and coronary artery operation. Aortic valve disease was present in 30 patients, mitral valve disease in 13, aortic and mitral valve disease in 1, and tricuspid valve disease in 1. The average age was 57 years. Seventeen patients were in New York Heart Association Functional Class IV. Seventeen patients had had a previous myocardial infarction. Significant coronary artery disease was an unexpected finding at the time of coronary angiography in 14 patients. The average number of grafts inserted was 2.5 per patient. The grafts were placed prior to valve replacement, and periods of myocardial ischemia were kept at a minimum by maintaining coronary perfusion throughout the operation. Operative mortality was 16%; late mortality was 8%. Perioperative myocardial infarction occurred in 2 patients.

Abstract
Of 60 patients aged 45 to 66 years with aortic valve stenosis, 28 (47 per cent) had angina pectoris. Significant coronary arterial obstruction was shown by selective coronary cineangiography in 14 of them. Systolic pressure gradients across the aortic valve were lower in patients with angina than in those without. In those with angina, systolic gradients were higher in those with normal coronary arteriograms than in those with demonstrable coronary arterial disease. Aortic valve replacement relieved the angina in all patients who had normal coronary arteriograms. When valve replacement was combined with coronary bypass grafting in those with coronary arterial disease, surgical mortality was higher and symptomatic relief less predictable. Incapacitating angina in patients with aortic stenosis was nearly always associated with significant coronary disease. In those with less severe angina it was impossible to predict the state of the coronary arteries. Two patients, who did not have angina and who did not undergo coronary arteriography, died after aortic valve replacement and were found at necropsy to have unsuspected severe coronary disease. We, therefore, suggest that coronary arteriography should be carried out in all patients over the age of 40 years in whom surgery is being considered for aortic stenosis.

Abstract
The surgical treatment of the completely obstructed left main coronary artery is aortocoronary saphenous-vein bypass to the left coronary artery system. Without surgical intervention, this lesion has an exceedingly poor prognosis. This report describes a patient with atherosclerotic obstruction of the left main coronary artery and congenital pulmonary valvular stenosis, an unusual combination of lesions not previously documented together. The patient remains asymptomatic 22 months after aortocoronary saphenous-vein bypass and pulmonary valvotomy.

Abstract
The data from 88 patients (pts) with aortic stenosis (AS) were reviewed to determine relationships between angina pectoris (AP) and coronary artery disease (CAD). Results of surgery performed in 81 of these pts was analyzed. All pts had coronary arteriograms, and lesions greater than or equal to 50% were considered significant. Fifty-nine pts had an aortic valve gradient measured at catheterization greater than or equal to 40 mmHg, and in 29 pts, AS was confirmed at operation. Sixty-eight pts (77%) experienced AP, and 32 had coexisting CAD (47%); 9 of 20 pts without AP had CAD (45%). There were no significant differences in the incidence of AP in pts divided into subgroups by the aortic valve gradient (40-50, 51-100, 101-200 mmHg) or age (40-59, 60-81 years). Also, no significant differences were found in the incidence or extent of CAD between the two age groups; the extent of CAD was similar regardless of the presence or absence of AP. In pts with AP (1) CAD was more likely in pts greater than or equal to 60 years of age; (2) CAD was less likely when the aortic valve gradient was greater than 100 mmHg, suggesting that AP in these pts was due to hemodynamically severe AS. All pts with 3-vessel CAD experienced AP, and the aortic valve gradient was less in these pts than in those with no CAD or less extensive CAD. In 19 pts with combined AS and CAD who had both the aortic valve replaced and a revascularization operation only 1 of pts died in the hospital, while 3 of 19 pts with combined AS and CAD who had aortic valve replacement alone died. In this study a significant number of pts with AS experienced AP, and the presence or absence of AP did not predict coexisting CAD. Coronary arteriography is recommended in the evaluation of pts greater than or equal to 40 years of age with AS. The operative mortality appears to be decreased in pts with AS and CAD who have combined surgery.

Abstract
Of 88 consecutive patients aged 20 to 77 years with severe symptomatic aortic valve disease requiring surgery, 51 patients had angina pectoris; of these 51, 41 had predominant aortic stenosis and 10 had severe aortic regurgitation. All patients with angina pectoris underwent coronary angiography; significant coronary arterial disease was encounted in 24 per cent of those with aortic stenosis and 20 per cent of those with aortic regurgitation. By contrast, of 37 patients without angina pectoris 19 underwent coronary arteriography; none showed significant coronary artery disease (P smaller than 0.05). Among patients with angina pectoris, 17 per cent of those with aortic stenosis experienced prolonged, rest or nocturnal pain, compared to 70 per cent of those with aortic regurgitation (P smaller than 0.005). At the time of onset of angina pectoris, there were features of heart failure in 34 per cent of those with aortic stenosis, and in 90 per cent of those with aortic regurgitation (P smaller than 0.005). Nitroglycerin promptly relieved angina pectoris in 56 percent of patients with aortic stenosis and in 50 per cent of those with aortic regurgitation (P smaller than 0.05). Neither the pattern of angina pectoris nor the response to nitroglycerin was dependent upon the coexistence of significant coronary artery disease. In patients with aortic stenosis, there was not significant difference between those with angina pectoris, and those without angina with regard to left ventricular end-diastolic volume, end-diastolic pressure, ejection fraction, peak systolic pressure, wall thickness, cardiac index, or the product of these factors. In patients with aortic regurgitation, cardiac index was significantly lower (P smaller than 0.05), left ventricular end-diastolic volume tended to be larger, and ejection fraction tended to be lower in patients with angina pectoris as opposed to those without angina pectoris.

Abstract
Twenty-eight patients who underwent aortic valve replacement and coronary artery bypass grafts (group A) were compared, with respect to clinical presentation, operative mortality and morbidity and follow-up clinical status, with 40 patients who had normal coronary arteriograms and underwent aortic valve replacement only (group B). Groups A and B had a similar incidence of angina pectoris, cardiomegaly, and radiographic evidence of congestive heart failure prior to operation. Group A had a higher incidence of positive history of congestive heart failure, electrocardiographic changes indicative of an old myocardial infarction, and pure aortic regurgitation or mixed aortic stenosis-aortic regurgitation. In patients with pure aortic stenosis, the aortic valve area was greater and the aortic valve gradient was lower when there was associated coronary artery disease. The operative mortality was 14.3% in group A; 0% in group B. Postoperative morbidity was similar, except for a higher incidence of perioperative myocardial infarction in group A (10.7% vs 0%). There have been no late deaths in group A; four in group B. In the survivors, 23 of 24 group A and 36 of 36 group B patients are in NYHA class I or II, with good relief of symptoms. We conclude that the diagnosis of coronary artery disease in aortic valve disease is difficult to make without coronary arteriography. Combined aortic valve replacement and coronary artery bypass graft surgery carries a higher operative mortality than aortic valve replacement or coronary artery bypass graft surgery alone, but the clinical results at 1-3 year follow-up are equally satisfactory.
