Anomalous aortic origin of the coronary arteries is uncommon but clinically significant. Manifestations vary from asymptomatic patients to those who present with angina pectoris, myocardial infarction, heart failure, syncope, arrhythmias, and sudden death. We describe 4 patients, aged 34 to 59 years, who were diagnosed with right coronary artery arising from the left sinus of Valsalva, confirmed by coronary angiography, which was surgically repaired. Three patients presented dyspnea and angina, and one with acute myocardial infarction. At operation, the right coronary artery was dissected at the take-off from the intramural course, and reimplanted into the right sinus of Valsalva. There was no mortality. One patient had associated coronary artery disease that required stent placement postoperatively. This reimplantation technique provides a good physiological and anatomical repair, eliminates a slit-like ostium, avoids compression of the coronary artery between the aorta and the pulmonary artery, and gives superior results to coronary artery bypass grafting or the unroofing technique.  相似文献

We present the clinical, angiographic and surgical findings in a 63-year-old man with anomalous origin of the left main coronary artery from the right sinus of valsalva. The course of the left main artery was abnormal in that it passed between the aorta and the pulmonary artery; in addition, there was obstructive disease involving the left main coronary artery. The association of these two entities in this age group is unusual.  相似文献

We present the case of a 67-year-old female who was admitted to our institution because of anginal chest pain. Selective coronary angiography revealed separate ostial origins of the left anterior descending (LAD) artery and the right coronary artery (RCA) from the right coronary sinus (RCS). The left circumflex (LCx) coronary artery arose from the proximal RCA. The left anterior descending had an anterior free wall and the LCx had a retroaortic course. To our knowledge, this type of combination of anatomical variation of coronary circulation has not been described in the literature.  相似文献

The clinical and angiographic findings in 10 patients with anomalous origin of the left main (LM) coronary artery from the right sinus of Valsalva are presented. The initial course of the anomalous artery was between the aorta and the pulmonary trunk in 6 patients (5 men and 1 woman), and posterior to the aorta in 4 patients (3 women and 1 man). The best coronary angiographic projection to determine the course of the LM coronary artery in relation to the aorta and pulmonary trunk was the right anterior oblique and lateral projections, with a catheter in the pulmonary trunk as a guide. In the right anterior oblique projection left ventriculogram, an increased density at the base of the aorta was seen in all patients with posterior-to-aorta course of the anomalous artery. The blood supply to the first portion of the ventricular septum is provided by 1 or 2 descending septal branches from the anomalous LM artery, when the anomalous vessel is coursing between the aorta and pulmonary trunk. When the anomalous LM courses posteriorly to the aorta, it does not provide any septal branches. In patients with this anomaly, the blood supply to the first portion of the septum is usually provided by descending septal branches originating from the right sinus of Valsalva or from the first portion of the right coronary artery. Six of the 10 patients had severe obstructive coronary artery disease. Four of the 6 patients had significant LM coronary artery disease.  相似文献

Ectopic origin of the right coronary artery is an infrequent anomaly. We report a case in which the right coronary artery arose from the ascending aorta above the left sinus. This anomaly was associated with a bicuspid aortic valve. Techniques for delineation of the ectopic origin of the right coronary artery are discussed.  相似文献

Various anomalies of coronary arterial origin have been described. These anatomical variations are discovered either by coronary angiography or at autopsy. We are reporting a case of anomalous origin of the right coronary artery above the left sinus of Valsalva. To our knowledge, this anomaly has not been described before. A technique for selectively catheterizing such an aberrant coronary artery is described.  相似文献

A 77-year-old male presented with a recent posterior myocardial infarction for coronary angiography. This angiogram revealed a rare, previously unreported anomalous origin of the right coronary artery from the proximal left anterior descending coronary artery distal to the first major diagonal branch.

This is the first presentation of anomalous origin of right coronary artery (RCA) from mid-left anterior descending (LAD) coronary artery. A 77-year-old male was catheterized because of recent onset of fatigue during exertion. The LAD demonstrated 50–60% narrowing just proximal to the anomalous origin of the RCA. The patient was maintained on oral medication. Cathet. Cardiovasc. Diagn. 44:328–329, 1998. © 1998 Wiley-Liss, Inc.  相似文献

We present the case of a patient with a dilated cardiomyopathy in which an anomaly in the origin of the left coronary artery, that arose from the right sinus of Valsalva through an own ostium and followed a retro aortic course, was recognized as an angiographic finding. The possible pathways the anomalous artery may follow, and their different clinical significances are reviewed. The angiographic sign of the aortic root, described for the identification of the anomalous origin of circumflex artery, is reviewed and its utility in the case of anomalous left coronary artery is demonstrated. In our case, Thallium-201 didn't show myocardial ischemia with the exercise and that justified, beside the doubtful efficacy of surgery as prophylaxis of sudden death when the anomalous course is retro-aortic, to maintain a conservative attitude.  相似文献

BACKGROUND: Anomalous origin of the right coronary artery (RCA) from the left coronary sinus can cause sudden cardiac death. Whether this unique anatomical defect also predisposes to early development of coronary artery disease (CAD) remains uncertain. METHODS: Demography, cardiovascular risk factor profiles and coronary angiograms were reviewed in 1,532 consecutive patients over the past 3 years. RESULTS: Thirteen patients (0.8%) had anomalous RCA from the left coronary sinus, while the rest had normal origin from the right coronary sinus. CAD was found in 9/13 anomalous RCA patients (group A) and in 795/1,519 patients with normal RCA origin (group B). There were no differences in the distributions of age, sex or cardiovascular risk factors between the two groups. The distribution of critical lesions among the 3 major coronary arteries showed no significant differences either. However, among the patients with RCA involvement, the anomalous RCA group was significantly younger (54.8 +/- 4.8 years versus 64.9 +/- 10.1 years; p = 0.022). CONCLUSION: The anomalous RCA from left coronary sinus is associated with early development of CAD. The affected patients are 10 years younger.  相似文献

A 41-year-old man with no relevant cardiac history presented for evaluation of episodic syncope. Electrocardiography showed sinus rhythm with right bundle-branch block and Q waves in leads II, III, and aVF. Subsequent exercise treadmill testing and technetium 99m sestamibi study revealed a reversible posterior defect. Coronary angiography later showed a right coronary artery that arose from the left coronary sinus--an anomaly that has been associated with angina, myocardial infarction, and sudden cardiac death. After being informed of the potential risks and options associated with this anomaly, the patient chose long-term beta-blocker medical therapy. At follow-up, this treatment appeared to have resolved his episodic syncope.  相似文献

The rare anomalous origin of the right coronary artery from the left sinus of Valsalva has recently been shown to be associated with myocardial ischemia and sudden death. A patient is presented with overwhelming evidence of myocardial ischemia corrected by a single-vessel bypass of the right coronary artery.  相似文献

Origin of the left circumflex coronary artery from the right sinus of Valsalva or the right coronary artery is a well-described anomaly. We report 3 cases which suggest a familial association of this anomaly. The familial clustering that we report has not been previously demonstrated. © 1993 Wiley-Liss, Inc.  相似文献
