The lordotic right posterior oblique projection of the left coronary artery is obtained by combining cranial angulation of the X-ray beam with rotation of the patient into the right posterior oblique position. This projection is helpful for separation of the main left coronary artery and the proximal portions of the left anterior descending and circumflex divisions, especially in patients in wh...

Coronary arteriography of a-72-year-old woman revealed prominent aneurysms of left main coronary, left anterior descending and right coronary arteries with a fistula from the left and right coronary systems draining into the right ventricular intramural hemangioma (Figs. 1 and 2). Fig. 1. Aneurysms of left main trunk and left anterior descending artery with normal appearance of circumflex arter...

In an 18-year-old asymptomatic male athlete, the left anterior descending coronary artery was found to arise from the pulmonary trunk. The remainder of the left coronary arterial tree arose through two stems from the aorta. Collateral retrograde filling of the left anterior descending coronary artery from the right coronary artery and the left circumflex coronary artery was demonstrated, but we...

We report the case of a rare anomaly of the right coronary artery originated from the middle third of the left anterior descending (LAD) coronary artery with a proximal atheromatous obstructive lesion immediately before the emergence of the right coronary artery (RCA). The patient underwent successful angioplasty with stent implantation in the left anterior descending coronary artery. Only 7 ca...

INTRODUCTION AND OBJECTIVE Patients with lesions of the proximal left anterior descending coronary artery are a special high-risk group. In the present study we analyzed the efficacy and safety of coronary stenting in such lesions and the factors related to a less favorable prognosis in long-term follow-up. METHODS Ninety-eight consecutive patients with severe left anterior descending artery ...

From 1984 to 1987, 537 consecutive patients (mean age 58 years; range 34 to 79) underwent angioplasty for proximal left anterior descending coronary artery disease. The procedure was clinically successful in 516 (96.1%). Procedural complications included myocardial infarction (2.2%; Q wave 0.9%, non-Q wave 1.3%), in-hospital bypass surgery (3%) and death (0.4%). Follow-up was obtained in 534 pa...

 Background: Coronary arteriovenous fistulas (CAVFs) are direct connections from one or more coronary arteries to cardiac chambers or a large vessel. They are mostly of congenital origin. The aim of this study was to describe clinical presentation and also delineate the course and management of CAVF. Methods: Clinical data, chest x-rays, echocardiographic and angiographic evaluation of...

Myocardial bridging, a congenital coronary anomaly, is a cluster of myocardial fibers crossing over the epicardial coronary arteries. It is most frequently seen in the left anterior descending artery (LAD), and rarely involves the circumflex (CX) and right coronary artery (RCA). We report a patient with an unusual coronary bridge crossing over the left anterior descending, obtuse marginal and r...

A patient with anomalous aortic origin of the left anterior descending coronary artery was studied. The clinical picture and the preliminary angiographic findings simulated obstruction of the left anterior descending coronary artery near its origin. Careful catheter exploration of the right coronary sinus led to the correct diagnosis, emphasizing the importance of complete visualization of all ...
