origination of the right coronary artery (rca) from the left anterior descending (lad) artery is a case of single coronary artery. it is an extremely rare coronary artery abnormality and usually an incidental finding during coronary angiography. a 73-year-old man with a medical history of hypertension arrived with chest pain. medical therapy started for st elevated myocardial ischemia. during h...

end stage coronary artery disease with linear stenosis of the main vessels despite several coronary interventions (including stent implantation) is a current challenge for surgical treatment. As the long term results are mainly determined by the pathology of the coronary vessels a simple revascularisation with arterial or venous grafts provides no adequate solution of the problem. An exactly co...

Certain failing enlarged ischemic hearts are difficult to treat by mammary implants, epicardiectomy, omental grafts. A new concept and operation has been experimentally tested, based upon the omental graft’s ability to form arteriolar communications with surrounding arteries within eight days. in animals, three coronary arteries were surrounded by ameroid constrictors. Three separate omental st...

The majority of studies on the control of coronary artery vasoactivity have examined changes in coronary blood flow and coronary vascular resistance, indices that primarily reflect regulation of small arterioles and precapillary vessels. With the emergence of coronary artery vasospasm as a significant cause of angina pectoris, myocardial infarction, and sudden death, the control of large corona...

UNLABELLED Abnormal exercise perfusion findings have been described as false-positive for coronary artery disease in patients with suspected angina and angiographically normal coronary arteries. METHODS The significance of this finding was further investigated by obtaining intravascular sonograms and Doppler guidewire measurements of at least 2 coronary arteries in 20 consecutive patients who...

This is a third part of tripartite morphometric data of the pig coronary blood vessels, giving a complete quantitative description of the arterial tree [Kassab et al., Am. J. Physiol. 265 (Heart Circ. Physiol. 34): H350-H365, 1993], capillary network [Kassab and Fung, Am. J. Physiol. 267 (Heart Circ. Physiol. 36): H319-H325, 1994], and venous tree (this article). Together they provide the quant...

Introduction: Cardiovascular disease (CVD) is a group of diseases that include both the heart and blood vessels, thereby including coronary (CHD) artery (CAD), acute syndrome (ACS) among several other conditions.

The branching pattern of the coronary arteries and veins is asymmetric, i.e., many small vessels branch off of a large trunk such that the two daughter vessels at a bifurcation are of unequal diameters and lengths. One important implication of the geometric vascular asymmetry is the dispersion of blood flow at a bifurcation, which leads to large spatial heterogeneity of myocardial blood flow. T...

The deep inferior epigastric perforator flap has become increasingly popular for breast reconstruction with the most common recipient vessels being the internal mammary artery and vein. In certain cases, however, these recipient vessels are inadequate due to an absent or diminutive vein. Moreover, patients at high risk for future coronary artery disease may sacrifice the best conduit for corona...

Abstract Fluorescent cardiac imaging can be applied for intraoperative quality control after a coronary bypass grafting surgery to ensure the myocardial perfusion by evaluating increasing contrast agent enrichment in heart. The motion due beating heart impedes interpretation of vessels and leads noisy curves. We propose tracking surface features compensate thereby improve analysis enrichment. F...
