The left coronary artery was seen originating in relation to the left posterior aortic sinus in 100% of the specimens. The incidence of bifurcation of the left coronary artery was found in 64% and trifurcation in 36%. In 26% of hearts the circumflex branch of the left coronary artery crossed the crux, in 20% the SA Nodal artery, and in 24% the AV Nodal artery was seen as a branch of the circumf...

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...

  Background :In addition to diagnosing the acute myocardial infarction (MI), stratifying high-risk patients and proper treatment strategies are important issues in managing patients complaining of chest pain and suspecting MI. Many studies have been conducted to predict the occlusion site by interpreting the ST segment deviations in Electrocardiogram (ECG).Additional posterior and right precor...

A rare aneurysm of a congenital coronary arteriovenous fistula is reported. Echocardiography showed a dilated left coronary and left circumflex artery with normal left anterior descending artery. A dilated structure near the crux was confirmed to be a large aneurysm of circumflex coronary artery on selective angiography. It drained into the posterior right atrial wall. Under cardiopulmonary byp...

For the success of anatomical correction of transposition of the great arteries (TGA) it is essential to transfer the coronary ostia to the posterior vessel without undue tension, torsion, or kinking of the proximal coronary arteries or their early branches. This requires thorough understanding of the different modes of origin and early branching of the coronary arteries in TGA. Based on observ...

The subclavian-axillary arterial tree is responsible for the arterial supply to the rotator cuff muscles as well as other shoulder muscles. This study comprised the bilateral dissection of the shoulder and upper arm region in thirty-one adult and nineteen fetal cadaveric specimens. The variable origins and branching patterns of the axillary, subscapular, circumflex scapular, thoracodorsal, post...

INTRODUCTION To date, only scant data has been reported regarding the anatomy of the radial nerve and profunda brachii artery and their relationships while within the triangular interval of the posterior arm. As this area has recently gained attention for using motor branches of the triceps muscle for nerve transfers, the present study was conducted. MATERIALS AND METHODS Fifteen adult cadave...

a 78-year-old woman was referred for coronary angiography with the chief complaint of exertional angina and dyspnea of a very long duration during routine daily physical activities. she had a history of poorly controlled hypertension and dyslipidemia. coronary angiography revealed diffuse three-vessel disease. interestingly, an unusual branch was noted originating from the mid shaft of the left...
