Outcome after Simultaneous Abdominal Aortic Aneurysm Repair and Aortocoronary Bypass

Myocardial infarction remains the leading cause of early and late death after abdominal aortic aneurysm (AAA) repair. Myocardial revascularization is staged either before or concomitant with AAA resection, but results are far from uniform. We retrospectively analyzed our experience with patients who underwent concomitant AAA resection and aortocoronary bypass (ACB) to examine the factors affecting early morbidity/mortality and early results. Forty-two patients (all men; mean age, 67.2 years) underwent simultaneous ACB grafting and AAA repair between 1975 and 1998. All were managed postoperatively in the cardiothoracic intensive care unit (mean stay, 6.1 days). The mean total hospital stay was 17.2 days. Two died in the early postoperative period (4.8%): 1 of sustained myocardial failure following a third ACB, and 1 of coagulopathy after concomitant ACB, aortic valve replacement, and AAA. One patient developed a nonfatal MI on postoperative day 3. The incidence of wound and bleeding complications was higher for patients undergoing both ACB and AAA repair than for patients undergoing AAA resection alone. On follow-up (mean, 10 years; range, 7 months to 15 years), only 2 of 10 late deaths were due to cardiovascular causes. We believe that concomitant myocardial revascularization is warranted in select patients requiring elective or urgent AAA resection in order to decrease perioperative risk and improve late survival. Cardiac failure or ischemia during aortic surgery can be prevented by proper perfusion with or without cardiopulmonary bypass. In patients undergoing simultaneous procedures, the increased risk is related to the severity of the vascular and coronary artery disease and not to the combined operations.     

Management of cholelithiasis in patients with abdominal aortic aneurysm.

Gallstones were detected in 42 of 865 patients with abdominal aortic aneurysm (4.9%). Eighteen patients underwent concomitant aneurysm resection and cholecystectomy. Eleven patients had aneurysmectomy without cholecystectomy. Thirteen patients underwent cholecystectomy alone. There were no significant increases in operative mortality, duration of operation, or length of hospital stay when cholecystectomy was added to aneurysm resection. However, there was one instance of prosthetic infection which occurred in a patient who did not have his graft retroperitonealized prior to cholecystectomy, and who also underwent gastrostomy and drainage of the liver bed. There have been no graft complications in the remaining 17 consecutive patients who had their graft retroperitonealized prior to cholecystectomy. Nine of 11 patients who underwent aneurysmectomy without cholecystectomy experienced an episode of acute cholecystitis during a mean follow-up period of 2.9 years. Two of these episodes occurred in the immediate postoperative period and one patient died of biliary sepsis. On the basis of these findings, concomitant aneurysmectomy and cholecystectomy is advised in those patients with cholelithiasis undergoing aortic aneurysm resection providing no contraindications exist.     

Anomalous origin and distribution of coronary arteries. Review of 38 patients who underwent operation.

Between October 1961 and December 1973, 38 patients with an anomaly in origin (15 patients) or distribution (23 patients) of the main coronary artery or one of its branches underwent operation at the Texas Heart Institute. The left coronary artery originating from the pulmonary artery occurred most frequently-in 13 of 15 patients. An aortocoronary artery bypass was performed in 12 patients with the saphenous vein used in ten of the 12, initially in 1965; and a Dacron tube graft in the other two. Of the 15 patients, only one died during the early period after operation. A follow-up of ten years revealed 11 asymptomatic patients; to date the longest period of patency of a saphenous vein graft is seven years in an 11-year-old girl. Of 23 patients with an unusual coronary artery distribution, 22 had tetralogy of Fallot, 20 of whom underwent total correction. In 21 of the 23 patients the left anterior descending coronary artery originated from the right coronary artery and crossed the right ventricular outflow tract. In two patients this abnormally distributed artery was injured through a vertical right ventriculotomy; both patients died from myocardial failure during the early postoperative period. Subsequently a transverse right ventriculotomy, either alone or combined with a right ventricular outflow and/or pulmonary artery patch enlargement was performed in 16 patients, and a double outlet right ventricle was created through insertion of a Dacron tube graft in two patients. With this method injury to the abnormal left anterior descending coronary artery was avoided and all 18 patients survived the operation. On the basis of our experience and today's advanced techniques, it is believed that most patients, including some under two years of age, can undergo correction of a left coronary artery originating from the pulmonary artery through insertion of a saphenous vein graft between the aorta and left coronary artery. During the surgical correction of cardiac anomalies necessitating a right ventriculotomy, a transverse or double incision in the right ventricular outflow tract in most patients will prevent injury to an abnormally distributed coronary artery branch; sometimes insertion of a Dacron tube graft between the right ventricular outflow tract and pulmonary artery is necessary.     

Surgical treatment of aortic arch aneurysm combined with coronary artery stenosis.

OBJECTIVE: We present operative results of aortic arch aneurysm associated with coronary artery stenosis, and evaluate the operative risk of graft replacement of the aortic arch and concomitant coronary artery bypass grafting (CABG). PATIENTS AND METHODS: From January 1991 to December 2001, we treated 16 patients with aortic arch aneurysm and coronary artery stenosis. The patients, 3 women and 13 men (study group) ranged from 58 to 79 years of age, average 68.1 5.3 years. With the aid of deep hypothermic cardiopulmonary bypass, we performed graft replacement of the aortic arch aneurysm and concomitant CABG. We bypassed 31 coronary arteries. The bypass grafts included saphenous vein (n=16), left internal thoracic artery (n=4), right internal thoracic artery (n=1), right gastroepiploic artery (n=5) and inferior epigastric artery (n=2). The number of bypassed coronary arteries per patient ranged from 1 to 3, average 2.1 0.8/patient. A comparative study was performed between the study group and a control group of patients (n=39) who had undergone only graft replacement of the aortic arch. RESULTS: There was no significant difference between the two groups regarding: operation time, cardiopulmonary bypass time, cardiac arrest time, intraoperative bleeding volume, and early mortality rate. However, in the patients (n=4) of the study group who had undergone total arch graft replacement with three vessel CABG, the cardiopulmonary bypass time was significantly longer than that of the patients in the control group who underwent total arch graft replacement (n=19, P<0.05). Two of the 16 study group patients died in the early postoperative period, resulting in 12.5% early mortality rate. In the control group, four of 39 patients (10.3%) died in the early postoperative period. CONCLUSIONS: CABG combined with graft replacement of the aortic arch does not increase operative risk when the number of bypassed vessels is within two vessels, but may increase risk when three or more vessels are bypassed.

心血管手术同期施行冠状动脉搭桥

为提高心血管手术同期施行冠状动脉搭桥（ＣＡＢＧ）的疗效,降低手术死亡率,作者于１９８４年１１月至１９９６年７月施行此类手术５１例,其中瓣膜手术４５例,室间隔穿孔和室壁瘤切除４例,左房粘液瘤摘除术和腹主动脉瘤切除术各１例。术后早期死亡３例,死亡率５．８８％（１９９０年以后为４．１７％）,晚期死亡３例。作者认为：５０岁以上或有心绞痛症状和心电图缺血依据的心血管外科患者,应常规行冠状动脉造影。对狭窄程度＞５０％的主要分支,在纠正其他心血管病变同时,须行ＣＡＢＧ。术中充分再血管化,注意心肌保护,尽量减少升主动脉阻断时间。     

The treatment of patients with recurrent ventricular fibrillation.

During the four year period from 1972 to 1975, eleven patients, eight with recurrent and three with first attacks of ventricular fibrillation, underwent aortocoronary bypass graft and/or resection of ventricular aneurysm. All patients had old myocardial infarction from seven weeks to six years. Left ventricular angiography demonstrated discrete aneurysm of the anterior wall of the left ventricle in nine of the patients and akinesis or hypokinesis of the anterior and posterior wall of the left ventricle in the remaining two. Coronary angiography was carried out in ten patients and revealed significant disease of the left anterior descending and right coronary arteries in ten and nine patients, respectively. There was no operative mortality, and there were two late deaths. Eight patients have improved significantly and have had no further sign of ventricular irritability. The present study indicates that aortocoronary bypass graft and/or resection of ventricular aneurysm is an effective method of therapy for patients with repeacted ventricular fibrillation who have ventricular aneurysm and ischemic heart disease.     

Incidence of postinfarction aneurysm within one month of infarct. Experiences with sixteen patients in Hawaii.

BACKGROUND: We report on sixteen patients with a left ventricular aneurysm presenting at less than a month following myocardial infarction. METHODS: All patients had significant left anterior descending coronary artery disease, and in eight cases (50%), this was the only significant pathology. Two patients who were treated conservatively, died within three months of infarction. RESULTS: Of the fourteen surgically treated patients, one died. There have been two late deaths, one at ten months and the other at four years postinfarction. Patients who present early after infarction, usually have a large anterior aneurysm, requiring early surgical repair with ventricular aneurysmectomy and revascularization. This group of patients showed a higher risk for major complications (such as thrombo-embolism, arrhythmias) and/or death. Emergency coronary artery bypass surgery may prove beneficial in the prevention of aneurysm formation by revascularizing the viable but ischemic tissue in that area.     

Left ventricular aneurysmectomy in patients with poor left ventricular function.

Physical performance and left ventricular (LV) function in the resting state were assessed in 22 patients with postinfarction anterior-apical left ventricular aneurysm (LVA) and global ejection fraction less than or equal to 20% who subsequently underwent radical LVA resection. The basic findings in the 20 survivors of surgery were significant improvement of global systolic LV function and more or less complete recovery of regional ejection fraction in the predominantly viable low and high lateral LV wall. This improvement was evident in patients with concomitant bypass grafting as well as in those with isolated and ungraftable lesions of the left anterior descending (LAD) coronary artery. We conclude that postinfarction anterior-apical LVA in a poorly functioning LV is suitable for surgical treatment, which can be accomplished with acceptable risk. All graftable stenotic major coronary arteries should be bypassed, in addition to the LVA resection, but a minority of patients with isolated, ungraftable LAD disease are likely to benefit from aneurysmectomy alone.     

The effect of coronary bypass on the outcome of peripheral vascular operations in 1093 patients

One of the greatest risks in peripheral vascular operations is the presence of significant coronary artery disease. To assess the proper timing and demonstrate a possible protective effect of coronary artery bypass (CAB), 1093 patients who underwent one or more peripheral vascular operations in addition to CAB from 1976 through 1984 were analyzed. During that same period, 24,441 patients underwent CAB procedures, and 8530 patients underwent major vascular operations. Carotid endarterectomy (493 patients), abdominal aneurysm resection (130 patients), renal artery bypass (12 patients), aortofemoral bypass (77 patients), femoral-popliteal-tibial bypass (190 patients), and combined vascular procedures (191 patients) were included. The patients were divided into three groups according to severity of disease, which determined timing of the procedure. Group I (255 patients) underwent simultaneous CAB and peripheral vascular operation because of unstable coronary artery disease and severe vascular disease. The early mortality rate for group I was 4% (10 patients). Seven of the 10 deaths were cardiac. In group II, 279 patients had CAB and peripheral vascular operation during the same hospital admission with the same operative mortality rate (4%, 10 patients). Six deaths were from cardiac causes, three from neurologic causes, and one from hemorrhage. In group III, 559 patients underwent CAB first, then peripheral vascular operation during a separate hospital admission. There were no cardiac-related deaths and only one neurologic-related death (operative mortality rate, 0.2%). These data demonstrate the protective effect of CAB in patients who undergo elective vascular surgery. The increased risk in patients undergoing simultaneous or same admission procedures was related to the severity of the vascular and coronary artery disease and not to the combined operations. Operative complications were not increased by performing simultaneous or same admission procedures.     

Coronary artery bypass with ventricular restoration is superior to coronary artery bypass alone in patients with ischemic cardiomyopathy

BACKGROUND: Coronary artery bypass is an acceptable therapy in patients with ischemic cardiomyopathy. However, it has been demonstrated that patients with increased left ventricular volume have a worse outcome than patients with normal ventricular volume. Our hypothesis was that ventricular restoration plus coronary artery bypass provides improved outcome compared with coronary artery bypass alone in ischemic cardiomyopathy with ventricular enlargement. METHODS: A retrospective analysis was performed of patients with ischemic cardiomyopathy (ejection fraction <30%) who underwent operation between 1998 and 2002. Patients with enlarged ventricles (end-diastolic dimension > or =6.0 cm) who underwent either coronary artery bypass alone or coronary artery bypass with ventricular restoration were compared. Preoperative and postoperative ejection fraction, morbidity, mortality, and freedom from heart failure (hospitalization secondary to heart failure) were assessed. RESULTS: Ninety-five patients were included in the study. Thirty-nine patients had coronary artery bypass alone, whereas 56 patients had ventricular restoration with coronary artery bypass. Both groups demonstrated an improved postoperative ejection fraction; however, the improvement was significantly greater in the ventricular restoration plus coronary artery bypass group (P <.01). There were no hospital deaths in either group; however, late mortality was higher in the coronary artery bypass group. Freedom from heart failure was achieved in all but 2 of the ventricular restoration plus coronary artery bypass patients (2/56, or 3.6%) versus 7 in the coronary artery bypass group (7/39, or 18%). The combined outcomes of freedom from failure and late mortality were significantly improved in the ventricular restoration plus coronary artery bypass group (P <.05). CONCLUSIONS: Ventricular restoration affords significant improvement in ejection fraction compared with coronary artery bypass alone, without added mortality. Most importantly, left ventricular restoration reduces late morbidity and mortality compared with coronary artery bypass alone in patients with large ventricles.     

Elective operations for post-infarction left ventricular aneurysms.

During a two-year period (February 1973 to February 1975) 20 consecutive patients with post-infarction left ventricular aneurysm, seen at the Wessex Cardiac and Thoracic Centre, underwent aneurysmectomy with or without aorta-to-coronary artery saphenous vein bypass grafts, ventricular septal defect closure, or valve replacement. The diagnoses were established by clinical means, plain chest radiographs, left ventriculography, and selective coronary arteriography. The indications for surgery were uncontrollable congestive heart failure and angina, ventricular arrhythmias, or a rapidly growing aneurysm. Low cardiac indices or high left ventricular end-diastolic pressure were not considered to be contraindications to operation. Resection of the left ventricular aneurysm was performed with the use of normothermic cardiopulmonary bypass with haemodilution. In addition to the aneurysmectomy, four of these patients had concomitant closure of post-infarction ventricular septal defects; four had valve replacements; two had grafts to coronary arteries; and one had both replacement of the mitral valve and a right coronary vein graft. There were two hospital deaths (10%) and two late deaths (10%), making an overall mortality of 20%. All but one of the deaths were related to coronary artery disease. The survivors are active, and their rehabilitation was satisfactory. The longest survivor is doing well two years after left ventricular aneurysmectomy, ventricular defect closure, and tricuspid valve replacement. It is evident from our experience and from the reports of others that surgery has an established place in the management of post-infarction left ventricular aneurysm.     

Results from coronary artery bypass surgery combined abdominal aortic aneurysm repair.

OBJECTIVE: Complication from coronary artery disease is a major cause of mortality and morbidity in patients undergoing abdominal aortic aneurysm repair. We report our results from coronary artery bypass surgery performed in combination with abdominal aortic aneurysm repair in patients with coronary artery disease and abdominal aortic aneurysm, each being an indication for an emergency operation. METHODS: Seventeen patients underwent combined coronary artery bypass surgery and abdominal aortic aneurysm repair. The mean age of the patients was 67.6 +/- 5.2 years. Four had left main disease, 8 patients had triple-vessel disease, and 12 had a prior myocardial infarction. The average left ventricular ejection fraction was 0.49 +/- 0.13. The average abdominal aortic aneurysm diameter was 6.2 +/- 1.0 cm (range 4.5-8.0 cm). Thirteen patients underwent coronary artery bypass surgery followed by abdominal aortic aneurysm repair after discontinuation of cardiopulmonary bypass. In the remaining four patients, including one patient with severe left ventricular dysfunction, cardiopulmonary bypass was continued as a circulatory assist until the abdominal aortic aneurysm repair was completed. The left internal thoracic artery was used in 14 patients, and the right internal thoracic artery in one patient. RESULTS: Postoperative surgical complications occurred in three patients (bleeding in one patient requiring reoperation, abdominal subcutaneous wound infection in another and transient neural disorder in the others). There were no surgical or in-hospital death. There was no late cardiac complication and no late cardiac death after a mean of 29 months follow-up. CONCLUSIONS: We concluded that combined surgery was reasonable for selected patients with combined coronary artery disease and abdominal aortic aneurysm, each of which is an indication for an urgent operation. The aortic aneurysm repair during cardiopulmonary bypass for patients with severe left ventricular dysfunction was safe and effective.     

Surgical treatment of giant coronary artery aneurysm

OBJECTIVE: Giant coronary artery aneurysm is an extremely uncommon disease. Most previous reports have involved only single cases. This report describes 6 patients with giant coronary artery aneurysm, examines its causes, and aims to establish the optimal surgical strategies for this exceptional and rare pathology. METHODS: From July 1996 to October 2004, a total of 30,268 patients underwent heart surgery at Fuwai Hospital in Beijing. Among these, 6 patients had giant coronary artery aneurysm diagnosed and underwent operation. Various surgical strategies were used for the operations of these 6 patients, such as coronary artery aneurysm resection, coronary artery reconstruction, and concomitant coronary bypass. Additional procedures, such as fistula closure, aortic valve replacement, aortoplasty, and embolectomy, were done at same time for the patients with complications of coronary fistula, aortic valve insufficiency, or thrombus. Patients were followed up from 8 to 87 months, with a mean of 48 months. Doppler echocardiography, ultrafast computed tomography, and 3-dimensional aerial image studies were performed during follow-up. RESULTS: Five of these six cases were found combined with coronary artery fistula, and the cause for these giant coronary artery aneurysms was congenital. The remaining case was caused by atherosclerosis. After surgery, all patients recovered uneventfully, without in-hospital mortality. None died during the follow-up, nor did any have recurrence of the symptoms or giant coronary artery aneurysm. CONCLUSION: Giant coronary artery aneurysm is a rare entity that is commonly caused by congenital malformation and combined with other cardiac anomalies. An optimal surgical operation should be based on the specific cardiac anomaly of the individual patient.     

Unstable angina pectoris. Factors influencing operative risk.

Experience was reviewed with 471 consecutive patients who had coronary artery bypass (CAB) operation alone. The hospital mortality rate was 2% in 341 patients operated on for treatment of stable angina pectoris. There were ten deaths (7.7%) in the 130 patients who underwent CAB for treatment of unstable angina. In this series, age greater than 70 years, poor left ventricular function, distal coronary arteries unfavorable for grafting and the presence of main left coronary artery disease were factors associated with increased operative mortality. In 78 patients with unstable angina who had none of these increased risk factors, the mortality rate was 1.3%. Hospital mortality was 33% in patients older than 70 years and 29% in patients with poor left ventricular function and/or distal vessels unfavorable for grafting. In 23 of the 130 patients, the only increased risk factor present was severe stenosis of the main left coronary artery and one of them (4.3%) died. Thus, when elderly patients and patients with poor left ventricular function or poor distal vessels were excluded, the hospital mortality rate associated with CAB in patients with unstable angina was low (2.0%, 2/101 patients) and equal to that for operation in patients with stable angina pectoris.     

Aorta-coronary bypass in patients with coronary artery disease who do not have angina

During an 8 year period we performed coronary bypass operations in 118 consecutive patients who were not experiencing angina when selected for surgical treatment. Their mean age was 45 years, collectively they had had 87 myocardial infarcts, and 42% had at least moderately abnormal ventriculograms. Considering 50% coronary stenosis "significant," 9% had single-, 23% double-, and 68% triple-vessel disease; 15% had left main coronary artery disease also. Operations, which involved placing a mean of 3.6 grafts per patient, included 39 endarterectomies and 11 ventricular aneurysm repairs. There were no operative deaths, but eight (6.8%) died during a mean 6.7 year follow-up. A retrospective comparison was made between these 118 patients and a consecutive series of 605 others, mean age 46 years, having angina and also treated surgically during the same period. Five (0.83%) of these latter patients died perioperatively and 42 (6.9%) during a mean follow-up of 6.4 years. The no-angina patients had significantly more prior myocardial infarcts and more abnormal ventriculograms; the angina group had a significantly higher reoperation rate. However, there were no significant differences between the two groups in age, coronary disease severity, results of treadmill testing, number of grafted vessels, endarterectomies, ventricular aneurysm repairs, perioperative infarcts, operative or late mortality, or early, 1 year, and 5 year graft patency rates. We have concluded that, with the exception of cardiac ischemia warning, our patients without angina, treated surgically, were similar in most important respects to patients in a concurrent series in which angina was one of the indications for operation. We believe that coronary bypass is safe for such individuals without angina and probably as as effective as for those with cardiac pain.     

Fatal myocardial infarction following abdominal aortic aneurysm resection. Three hundred forty-three patients followed 6--11 years postoperatively.

Routine preoperative coronary angiography has been recommended to all patients scheduled for elective abdominal aortic aneurysm resection at the Cleveland Clinic since 1978. Patients found to have severe, correctable coronary artery disease (CAD) have been advised to undergo myocardial revascularization prior to aneurysm resection in an attempt to reduce the incidence of fatal postoperative myocardial infarction. In order to provide an historic standard with which the results of this approach may eventually be compared, complete follow-up information has been obtained for 96% of 343 consecutive patients who underwent abdominal aortic aneurysm resection between 1969 and 1973. Fatal myocardial infraction accounted for 37% of early postoperative deaths and occurred in 6% of the entire series. Among the patients who survived operation, the five-year mortality rate was 31% and the 11-year mortality rate was 52%. Complications of CAD caused 39% of the deaths that occurred within five years after operation and 41% of the deaths that occurred within 11 years. The late incidence of fatal myocardial infarction among patients who had preoperative evidence of CAD was statistically significant (p < 0.05).     

Surgical resection of acute post-myocardial infarction ventricular aneurysm. A clinical study

Clinical follow-up of 24 patients who developed left ventricular aneurysm early after myocardial infarction is presented. All patients developed left ventricular failure within two weeks of infarction. The indication for operation was resistant left ventricular failure in 21 patients and a combination of left ventricular failure and unstable angina in three. Complete occlusion or severe stenosis (greater than 70 per cent) of the left anterior descending coronary artery was the most common findings. There were 3 hospital (12.5 per cent) and 2 late (8.3 per cent) deaths. Impairment of septal mobility was associated with a poor prognosis. All patients who develop progressive left ventricular failure early following myocardial infarction should be clinically and haemodynamically evaluated for the presence of left ventricular aneurysm. Surgical resection of the aneurysm and correction of associated lesions should be aggressively pursued.     

Left ventricular aneurysm repair with myocardial revascularization: an analysis of 246 consecutive patients over 15 years

From 1970 to 1985, 246 consecutive patients with left ventricular (LV) aneurysm underwent repair and concomitant myocardial revascularization at Ochsner Foundation Hospital. The overall incidence of perioperative death was 7.3%. Although the deaths were mainly cardiac related (10/18) with congestive heart failure (CHF) as the leading cause (6/10), 8 deaths were of noncardiac origin. Perioperative mortality increased significantly in patients with mitral regurgitation (MR) (22%; p = 0.0008); perioperative mortality for patients without MR was 4.8%. The overall 5-year survival was 69%. Late deaths were caused most commonly by myocardial infarction (20/32) with only 7 due to CHF. Predictors of long-term survival were related to LV function preoperatively: absence of CHF (p = 0.001); LV end-diastolic pressure less than or equal to 20 mm Hg (p = 0.03); and ejection fraction greater than or equal to 35% (p = 0.02). Factors that did not significantly affect long-term survival were type of aneurysm repair (resection or plication), morphology of left anterior descending coronary artery (occlusion or stenosis), and size of the aneurysm.     

Influence of coronary artery disease and left ventricular dysfunction on postoperative mortality in vascular surgery.

In an attempt to assess the influence of coronary artery disease and left ventricular dysfunction on postoperative mortality, 107 patients consisting of 32 AAA resections and 44 aortoiliac and 31 femoropopliteal reconstructions were reviewed. All patients had a preoperative coronary angiograms and underwent cardiac catheterization to prevent cardiac-related deaths. Severe coronary artery disease was angiographically demonstrated in 40.6% of AAA, 31.8% of AI and 3.2% of FP patients. Severe left ventricular dysfunction was found in 21.9% of AAA, 18.2% of AI and 6.5% of FP. Both of the early and 5 (45.5%) of the 11 late deaths were caused by cardiac events. The nine-year survival rate (53.3%) in the patients with a documented combination of coronary artery disease and left ventricular dysfunction was significantly lower than those in patients with normal disease, normal left ventricular function and either documented coronary artery disease or left ventricular dysfunction. It is suggested from this series that left ventricular dysfunction is one of the most important risk factors in patients who undergo AAA resection and AI reconstruction and that severe disease and postoperative mortality are possibly reduced by certain kinds of interventional coronary therapies.
