OBJECTIVE To assess the results observed during the early postoperative period in patients who had the posterior coronary arteries revascularized without cardiopulmonary bypass (CPB), in regard to the following parameters: age, sex, bypass grafts types, morbidity and mortality. METHODS From January 1995 to June 1998, 673 patients underwent myocardial revascularization (MR). Of this total, 607...

Wiring through stent struts into a jailed side branch can be challenging. We describe a case of double-barrel left main coronary artery stenting into the first obtuse marginal branch that resulted in significant ostial circumflex coronary artery stenosis. We were unable to wire the jailed large distal circumflex artery. We introduced the Twin-Pass catheter over the first obtuse marginal wire, p...

The current trend in coronary artery surgery is to revascularize the left coronary artery branches with bilateral internal thoracic arteries (ITA). For this procedure, the right ITA is usually grafted to the left anterior descending coronary artery while the circumflex coronary artery is revascularized by the left ITA. The mid to long-term results of the left ITA on the circumflex system were e...

introduction: the persian squirrel (sciurus anomalus) is considered the only well-known species of the family sciuridae in the middle east. since some people keep this squirrel as a domestic pet, their attendance at veterinary clinics is increasing. so far, no study has been conducted on the arterial supply of the pelvic cavity and limb in the squirrel. hence, this research was performed to fil...

BACKGROUND The main objective of this study is to describe a new surgical technique that, through a gleno-humeral approach, reduces the incongruent joint while a humeral head centering osteotomy achieves shoulder stabilization. A humeral medial derotational osteotomy is performed associated with the articular reduction. PATIENTS AND METHODS Fourteen patients with obstetrical palsy presenting ...

The arterial blood supply to the canine AV (atrioventricular) node mainly through the posterior septal artery has been confirmed by LUMB et al.1) and later by JAMES2), while a considerable part of the interventricular septum is supplied by the anterior septal artery.WEST at al.8 described a technique for the catheterization of individual branches of the coronary artery in intact dogs which perm...

M yocardial infarction is a well recognized but infrequent complication of coronary arteriography. In most cases, it has usually been attributed to coronary artery dissection, dislodgement of an arteriosclerotic plaque, sustained hypotension, thromboembolism or spasm of the vessel.’ Fatal thromboembolism following coronary arteriography has rarely been confirmed by postmortem examination since ...

Whether endothelium-derived relaxing factor (EDRF)/nitric oxide (NO) plays a role in the dilation of the left circumflex coronary artery during acute exercise and whether endothelium-mediated dilation of this artery is altered after chronic exercise training have not been determined previously. Nine dogs were chronically instrumented for measurements of systemic hemodynamics, left circumflex co...
