BACKGROUND The study objective was to evaluate the role of transesophageal echocardiography in identifying the origin of anomalous coronary arteries and confirming their course in relation to the great vessels. The diagnosis of coronary anomalies is made by angiography. The anomalous left main artery with a course between the pulmonary artery and the aorta has been associated with myocardial in...

Single right coronary artery with congenital absence of left coronary artery is one of the rarest coronary artery anomalies. Most coronary anomalies are asymptomatic and incidental findings. We report a case of single right coronary artery with congenital absence of left coronary artery detected by coronary CT angiography. Physical examination revealed a well-nourished female with a blood press...

Background. Intracoronary ultrasound (ICUS) has the ability to quantitatively evaluate vessel wall morphology and is well suited for serial studies of coronary artery disease regression and progression. However, the potential risk for catheter-induced endothelial damage and accelerated atherosclerosis in instrumented vessels is a concern. The acute effects as well as the 1-year safety of ICUS r...

Coronary anomalies are rare, with a reported prevalence of 1.3% among patients who undergo coronary angiography. The great majority of coronary artery anomalies are incidental findings and are not clinically significant, but in some cases, may be responsible for angina, syncope, arrhythmias or even sudden death. In the following case, we describe coronary CT angiography findings of one of the r...

Abstract Coronary Artery Disease (CAD) is commonly diagnosed using X-ray angiography, in which images are taken as radio-opaque dye flushed through the coronary vessels to visualize severity of vessel narrowing, or stenosis. Cardiologists typically use visual estimation approximate percent diameter reduction stenosis, and this directs therapies like stent placement. A fully automatic method seg...

Congenital coronary artery anomalies are one of the causes of myocardial ischemia and sudden death in the young, mainly during sports. Origin of the right coronary artery from the left anterior descending artery is very rare, with a prevalence of 0.015%, corresponding to 1.2% of all coronary artery anomalies. The authors present the case of a 22-year-old man, with a history of cocaine use, admi...

BACKGROUND In patients with type 1 diabetes mellitus, atherosclerosis occurs earlier in life and coronary artery disease (CAD) constitutes the major cause of death. OBJECTIVE Evaluate the prevalence and anatomic characteristics of coronary artery disease (CAD) in type 1 diabetic patients with chronic renal failure undergoing hemodialysis. METHODS This is a descriptive study of 20 patients w...

Congenital coronary artery anomalies are of major significance in clinical cardiology and cardiac surgery due to their association with myocardial ischaemia and sudden death. Such anomalies are detectable by imaging modalities and, according to various definitions, their prevalence ranges from 0.21 to 5.79%. This consensus document from the Development, Anatomy and Pathology Working Group of th...
