Coronary artery anomalies are a rare type of congenital anomalies with an incidence of 1.3% during routine cardiac catheterization. Anomalous origin of the coronary arteries is considered an incidental finding without clinical significance. This case describes a patient in whom evaluation of chest pain revealed an obstructive left anterior descending artery as well as an anomalous right coronar...

with a history of arterial hypertension and dyslipidaemia, was admitted to our department for a scheduled coronary angiographic examination. Two months before entry, the patient had been admitted to another hospital for an extensive anterior myocardial infarction, treated with intravenous thrombolysis. The coronary angiogram recorded one week after the acute infarction depicted an ulcerated ath...

A 61-year old female presented with cardiac arrest. The diagnostic process following successful cardiopulmonary resuscitation was consistent with a left anterior descending to pulmonary artery fistula (Figs. 1 and 2). The patient underwent surgical ligation of the fistula, under cardiopul-monary bypass without complications. Fig. 1. Coronary angiogram showing fistulous vessel (arrow) from the l...

 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...

AIMS The accuracy of magnetic resonance angiography in detecting proximal coronary artery stenoses is unclear. We postulated that fast magnetic resonance angiography is capable of (1) imaging proximal coronary arteries, and (2) detecting stenoses of > or = 50% of their luminal diameter. METHODS AND RESULTS Thirty-five patients, referred for analysis of angina pectoris, underwent both conventi...

OBJECTIVE To perform a comparative assessment of two surgical techniques that are used creating an acute myocardial infarc by occluding the left anterior descending coronary artery in order to generate rats with a left ventricular ejection fraction of less than 40%. METHODS The study was completely randomized and comprised 89 halothane-anaesthetised rats, which were divided into three groups....

The purpose of this study was to determine the coronary microvascular sites of autoregulation. The epimyocardial coronary microcirculation was observed through an intravital microscope by stroboscopic epi-illumination in anesthetized open-chest dogs (n = 20). Aortic pressure and heart rate were held constant by an aortic snare and atrial pacing, respectively. Distal pressure of the left anterio...

Although dual left anterior descending arteries are found in about 1% of the population, identification and localization these coronaries remains a challenge for cardiac surgeons throughout coronary artery bypass graft surgery. We present case (LAD) disease highlight techniques used identifying vessels.

A single coronary artery (SCA) arising from the sinus of Valsalva and supplying the entire heart is a rare congenital anomaly. According to the modified Lipton's classification, R-1 is by far the most rare subtype of SCA, with an incidence of 0.0008% in patients undergoing coronary angiography. We present a case with an unreported anomaly, classified as Lipton R-I subtype, which initially follo...

BACKGROUND The objective was to evaluate the impact of complete revascularization (CR) versus reasonable incomplete surgical revascularization (IR) in others than left anterior descending artery territory on early and late survival in patients with multivessel coronary artery disease (CAD). METHODS AND RESULTS During a 7-year period, 8.806 consecutive patients with multivessel CAD affecting t...
