Sekctive coronary artedography by the Judkins' technique cao he readily accomplished in dextrocprdin. CinersdialCrspbs should be obtained in tbe mirror image obliquities for each coronary vessel and card&c cbamher. To avoid any potentid error of identitication and interpretation of the coronary vessels, films could he reviewed in revenre fashion, which would project the cardiac stnretwesasiftbe...

As compared with the totality of congenital malformations of the heart, anomalies of the coronary vessels are relatively rare. In the literature, anomalous origin of these vessels has been taken adequately into account. Less emphasis has been laid, however, on conditions such as congenital aneurysms of the coronary arteries which probably occur more frequently than is commonly believed. The fol...

Identifying coronary artery progenitors and their developmental pathways could inspire novel regenerative treatments for heart disease. Multiple sources of coronary vessels have been proposed, including the sinus venosus (SV), endocardium and proepicardium, but their relative contributions to the coronary circulation and the molecular mechanisms regulating their development are poorly understoo...

Traditionally, the coronary circulation was divided into two arterial compartments: the conduit and the resistive vessels. It has become apparent that there is substantial heterogeneity in resistive vessels with respect to the regulation of coronary flow, which is modified by the perfusion pressure, flow, myocardial metabolism, and ventricular wall tension. Early in the atherosclerotic process,...

Annual coronary arteriograms have been obtained from all heart transplant recipients at Stanford University Medical Center since 1969. Angiographic lesions in 81 transplant patients exhibiting coronary vascular disease were classified into three categories: type A, discrete or tubular stenoses; type B, diffuse concentric narrowing; and type C, narrowed irregular vessels with occluded branches. ...

Background and Aims: Bilirubin has been considered an antioxidant that protects against atherosclerosis. The aim of this study was to evaluate the relationship of serum bilirubin level with the severity and complexity of coronary artery disease (CAD) and long-term outcome in the patients undergoing primary percutaneous coronary intervention (PCI). Materials and Methods: This prospective coho...

The coronary vasculature has been traditionally divided into three functional groups: large conductance vessels visible on coronary angiography, which offer little resistance to blood flow; small resistance vessels ranging in size from about 250 to 10 μm in diameter; and veins. Although it has been taught that arterioles (precapillary vessels < 50 μm) account for most of the coronary resistance...
