A 59-year old male, with a history of inferoposterior myocardial infarction and multiple coronary stenting, presented to the out-patient clinic with exercise-related chest discomfort. The electrocardiogram showed sinus rhythm with Q-waves in the inferior leads (Figure 1). Coronary computed tomography angiography (CTA) showed stents in the right coronary artery (RCA), left anterior descending ar...

Coronary artery ectasia (CAE) is an uncommon anomaly, usually found in 1.2-2% of patients undergoing coronary angiography, defined as a segment of the coronary artery that has a diameter of more than 1.5 times the normal adjacent segments. Atherosclerosis is considered as the cause of half of the CAE cases. We herein present a 65-year-old Asian male with past medical history of Kawasaki disease...

A 49-year-old woman presented with 3 weeks of exertional chest pain. A trans-esophageal echocardiogram with color Doppler was suggestive of a large coronary artery fistula 3.1 2.4 cm in size, originating from the left main coronary artery and emptying into the superior vena cava–right atrial junction. Coronary angiography demonstrated a dilated left main coronary artery with a giant fistulous c...

background coronary artery anomalies are not common, but could be very serious. objectives this study determines the frequency of coronary anomalies and normal variants by multi-detector-row computed tomography (mdct). patients and methods the results of cardiac mdct study in 2697 consecutive patients were analyzed retrospectively. acquisition was performed by a 64-detector row ct machine. imag...

Today, the use of cardiovascular magnetic resonance (CMR) is widespread in clinical practice. The increased need to evaluate of subtle myocardial changes, coronary artery anatomy, and hemodynamic assessment has prompted the development of novel CMR techniques including T1 and T2 mapping, non-contrast angiography and four dimensional (4D) flow. T1 mapping is suitable for diagnosing pathologies a...

aneurysms of the left main coronary artery are exceedingly rare clinical entities, encountered incidentally in approximately 0.1% of patients who undergo routine angiography. the most common cause of coronary artery aneurysms is atherosclerosis. angiography is the gold standard for diagnosis and treatment. depending on the severity of the coexisting coronary stenosis, patients with left main co...

introduction: heart failure is a major hazard for public health. despite recent advance in medical therapy, there is not enough information on the outcome of off-pump coronary artery bypass (opcab) and medical therapy on the patients with severe ventricular dysfunction and triple-vessel (cad). this study aimed to compare treatment outcomes and mortality rate in patients undergoing off-pump coro...

Six patients underwent cardiac catheterization before and after occurrence of a myocardial infarction. Results from the two procedures allowed the quantitation of changes in coronary artery anatomy and left ventricular performance associated with myocardial infarction. Left ventricular biplane or single plane angiography and selective coronary angiography were used to evaluate coronary artery a...

large intercoronary communications in the absence of obstructive coronary artery disease constitute a very rare coronary artery anomaly in which there is a readily visible connection between the 2 coronary arteries with a unidirectional or bidirectional blood flow; consequently, this anomaly may be misinterpreted as a functioning collateral vessel, indicative of an unrecognized proximal coronar...
