The anatomy of the coronary vessels has been described in detail for atleast 3 centuries. Detailed appreciation of the normal origin, course, branching and myocardial distribution of these vessels is vital so that variations of the normal anatomy can be more easily recognized and applied to clinical practice. Knowledge of normal anatomy and variations in the branching pattern of coronary arteri...

background: a good animal model for coronary surgery experiments has been difficult to establish. an ideal model should have the closest morphological resemblance to human beings. the objective of this study is to establish sheep as a model for these experiments. methods: the anatomical aspects of left anterior descending coronary artery (lad) and right internal thoracic artery (rita) in the sh...

While the anatomy of the coronary arteries in complete transposition of the great vessels has been studied by several authors, the overall problem of adequacy of the coronary blood supply in this condition has received less attention. Spitzer (1923) described the probable embryological basis for partial or complete transposition of the coronary arteries. Astley and Parsons (1952) thought that m...

traumatic coronary artery-cameral fistulas (tcaf) are rare and may present secondary to penetrating injuries (80%) or iatrogenic traumas. early operative intervention remains the recommended treatment modality for accidental traumatic coronary artery fistulas. we report the case of a 17-year-old man who presented with left anterior descending coronary artery-right ventricle fistula following pe...

results the mean ages in case and control groups were 60.8 ± 6.8 and 57.5 ± 11.5 years, respectively, with no significant difference (p = 0.09). thirty patients (54.5%) in case and 32 (58.2%) in control groups were male with no significant difference (p = 0.7). cmv-dna was present in 8 (14.5%) of the cases and 2 (4%) of the controls. cmv-dna was associated with higher risk of atherosclerosis (o...

In this issue of the Journal, Giraldi et al. (1) compare transvenous and epicardial lead placement in patients with unfavorable coronary sinus anatomy. Patients who met standard criteria for cardiac resynchronization therapy (CRT) including left ventricular (LV) dysfunction, New York Heart Association class III to IV congestive heart failure, and left bundle branch block, who were on optimal me...

conclusions following cabg, the most severity of pain was reported at surgical incision on time t2. pain began to decrease from the third day following the operation. age, sex and bmi along with operation-related factors such as duration of cbp or chest tube drainage may affect the pain pattern following cabg surgery. patients and methods the present study was conducted on 138 patients who unde...

Recent advances in CT technology have made possible the acquisition of high resolution images of the heart in which important anatomical features such as the coronary vessels are visible. The state of the art in MR Imaging techniques, on the other hand, typically provides lower resolution but can facilitate the differentiation of viable (healthy) cardiac tissue from infarcted (injured) tissue. ...

the acute coronary syndrome due to the left main coronary artery (lmca) thrombosis is a clinically rare and catastrophic event.   we describe a young man ( smoker, alcoholic, and drug abuser) with a history of recent surgery and typical chest pain who had non-occlusive lmca thrombosis in coronary angiography. the thrombosis was successfully treated with two 180 µ/kg intracoronary boluses of ept...
