Coronary anomalies are found in less than 1% of diagnostic coronary angiograms. The clinical importance of coronary anomalies varies from insignificant to life-threatening. We report a very rare case of a patient with two circumflex arteries originating from both right and left coronary sinuses of Valsalva.

AND ANOMALIES The right coronary artery (RCA) arises from the right coronary sinus and runs in the right AV groove (Fig. 5-1). Generally, the conus artery and the sinoatrial artery arise from the RCA. In approximately 85% of individuals, the posterior descending coronary artery arises from the RCA (defined as a right dominant coronary circulation). The left main coronary artery arises from the ...

OBJECTIVES/HYPOTHESIS To illustrate that a truncus bicaroticus and an elongated truncus brachiocephalicus are underestimated anatomic variations; and to highlight the risk of injury of these vessel anomalies during routine surgical interventions. DATA SOURCE Report of a woman with long-term ventilation who was planned for conventional surgical tracheostomy. Due to a strong pulsatile vessel cr...

PURPOSE To develop a respiratory motion correction framework to accelerate free-breathing three-dimensional (3D) whole-heart coronary lumen and coronary vessel wall MRI. METHODS We developed a 3D flow-independent approach for vessel wall imaging based on the subtraction of data with and without T2-preparation prepulses acquired interleaved with image navigators. The proposed method corrects b...

Background. Congenital anomalies of the coronary arteries are a cause of sudden cardiac death. Of the known anatomic variants, anomalous origination of a coronary artery from an opposite sinus of Valsalva (ACAOS) remains the main focus of debate. Case Series. We present three cases, all presenting to our facility within one week's time, of patients with newly discovered anomalous origination of...

Major coronary artery anomalies in a pediatric population: incidence and clinical importance. A et al. In vivo detection of coronary artery anomalies in asymptomatic athletes by echocardio-graphic screening. Prospective echocardio-graphic diagnosis and surgical repair of anomalous origin of a coronary artery from the opposite sinus with an interarterial course. Anomalous origin of right coronar...

We present a case of coronary ectasia and LAD coronary artery aneurysm with angiographic characteristics of Kawasaki disease in a three-yr-old girl two-yr status post-orthotopic heart transplant. Coronary anomalies were noted during initial screening coronary angiography two yr after transplant. Subsequent review of the donor echocardiogram revealed that the LMCA had been mildly dilated prior t...

BACKGROUND Coronary in-stent restenosis cannot be directly assessed by magnetic resonance angiography (MRA) because of the local signal void of currently used stainless steel stents. The aim of this study was to investigate the potential of a new, dedicated, coronary MR imaging (MRI) stent for artifact-free, coronary MRA and in-stent lumen and vessel wall visualization. METHODS AND RESULTS Fi...

vessel extraction is a critical task in clinical practice. in this paper, we propose a new approach for vessel extraction using an active contour model by defining a novel vesselness‑based term, based on accurate analysis of the vessel structure in the image. to achieve the novel term, a simple and fast directional filter bank is proposed, which does not employ down sampling and resampling used...

BACKGROUND Sudden death risk in Williams syndrome (WS) patients has been shown to be 25-100 times higher than in the general population. This study aims to detect coronary artery anomalies and myocardial perfusion defects in WS patients using noninvasive diagnostic methods. METHODS This study features 38 patients diagnosed with WS. In addition to physical examination, electrocardiography, and...
