Coronary Artery Anomalies

BACKGROUND: Most of our knowledge about atherosclerosis at young ages is derived from necropsy studies, which have inherent limitations. Detailed, in vivo data on atherosclerosis in young individuals are limited. Intravascular ultrasonography provides a unique opportunity for in vivo characterization of early atherosc…

BACKGROUND: Although myocardial ischemia is known to be significantly related to the development of coronary collateral vessels (CCVs), there is considerable variation between patients with ischemic heart disease in the presence of collateral development. The nature of this variability is not well known. Likewise, it…

Coronary artery aneurysms (CAAs) are uncommon and describe a localized dilatation of a coronary artery segment more than 1.5-fold compared with adjacent normal segments. The incidence of CAAs varies from 0.3 to 5.3%. Ever since the dawn of the interventional era, CAAs have been increasingly diagnosed on coronary angio…

BACKGROUND: Restenosis remains the major limitation of coronary catheter-based intervention. In small vessels, the amount of neointimal tissue is disproportionately greater than the vessel caliber, resulting in higher restenosis rates. In the Randomized Study With the Sirolimus-Eluting Bx Velocity Balloon-Expandable S…

BACKGROUND: Coronary artery anomalies are found in 0.2% to 1.3% of patients undergoing coronary angiography and 0.3% of an autopsy series. We aimed to estimate the frequency of coronary artery anomalies in our patient population. METHODS: The data were collected retrospectively by analyzing the angiographic data of 12…

OBJECTIVE: The reported experience with sinus of Valsalva aneurysms (SVAs) is limited. Our approach to this subset of patients and an algorithm-dependent classification are presented. METHODS: Between 1985 and 2000, 53 patients (mean age: 24+/-12; range 4--60) underwent repair for ruptured (64%) or non-ruptured (36%)…

BACKGROUND: Incomplete stent apposition (ISA) has been previously documented after sirolimus-eluting stent (SES) implantation. The aim of this study was to investigate the long-term intravascular ultrasound (IVUS) findings of ISA in patients who received SES. METHODS AND RESULTS: A total of 13 patients who received SE…

OBJECTIVE: Slow coronary flow (SCF) is a phenomenon characterized by delayed opacification of coronary arteries in the absence of epicardial occlusive disease, in which many aetiological factors such as microvascular and endothelial dysfunction, and small vessel disease have been implicated. We aimed to investigate th…
