BACKGROUND: Congenital left coronary artery abnormalities such as ostial stenosis or atresia are extremely rare. All patients had angina and two had aortic valve disease. There was mild luminal irregularity noted in the proximal and mid portions of the vessel. Eight patients developing coronary ostial stenosis following Starr-Edwards aortic valve placement are reviewed. In this review article, we review the epidemiology and pathophysiology of syphilitic aortitis and focus in on one of its complication, coronary ostial stenosis. FFR is defined as a ratio of the maximal myocardial blood flow in the presence of a stenosis to the theoretical normal maximal flow in … Coronary ostial stenosis is not uncommon in the aortitis syndrome because of the proliferation of the aortic wall inflammation. The goal of this book is to help general cardiologists, but also pediatricians and related care providers in the management and diagnosis of adult CHD. His initial physical examination, electrocardiographic results, and troponin level were normal. Int J Cardiol 1991;30:285--288. The mid, distal lesions are not significant, with less than 40 percent stenosis per IVUS evaluation.Following the coronary intervention with stent placement, there is marked increase in the ostial/proximal right coronary artery size, with no evidence for intimal disruption, no intraluminal filling defect, and TIMI III … 2.

Coronary ostial stenosis is a rare but potentially serious sequela after aortic valve replacement. While atresia of the left coronary artery ostium is a rare anatomic variant of the coronary circulation, atresia of the right coronary ostium is exceedingly rare and not reported in adults (1). Although ostial involvement causes symptoms The clinical symptoms are usually severe and may appear from 1 to 6 months postoperatively. A key issue in the treatment of an ostial lesion is to assure that the stent is inserted proximal enough to fully cover the aorto-ostial junction (particularly in the right coronary artery).

This text would benefit all health professionals involved in imaging congenital cardiac disease. Coronary ostial stenosis was shown in three of the four patients whose plaquing echoes were adjacent to the coronary orifice. Coronary angiography may result in catheter tip occulsion of the ostium with chest pain, dyspnea, diaphoresis, systemic hypotension and abrupt fall in pressure at the catheter tip. The ostia of the left and right coronary arteries are located just above the aortic valve, as are the left and right sinuses of Valsalva. Three cases of lethal ischemic heart disease are reported where occult ostial narrowing/occlusion was first identified at autopsy. x Heart failure (HF) remains a common complication for patients with coronary artery disease (CAD), especially after acute myocardial infarction. Anecdotal reports concern coronary ostial stenosis as acute complication. The restenosis rates reported in the literature varied, as high as 75 %. The LCX follows the left part of the coronary sulcus, running first to the left and then to the right, reaching nearly as far as the posterior longitudinal sulcus.There have been multiple anomalies described, for example the left circumflex having an aberrant course from the right coronary artery..

Echocardiographic measurements of the aortic root in the 32 heterozygotes were similar to the control group, but 10 patients showed abnormal bright echoes within the aortic cusps and four had supravalvular changes similar to, but less severe than, the homozygotes. The left anterior descending artery was also calcified in its ostial and proximal portions. ... Ostial Disease. Coronary ostial atresia, especially involving the RCA, is an extremely rare congenital coronary anomaly. In other cases, as in those reported herein, ostial stenosis/occlusion may be an additional contributing factor to global myocardial ischemia from coronary artery atheroma and/or other causes.
