Coronary artery aneurysms are relatively rare and commonly associated with significant coronary artery disease (CAD), inflammatory diseases (Kawasaki syndrome, infection), or iatrogenic complications. Herein, we report an unusual case of an incidental coronary aneurysm of the left main artery in a patient without specific clinical symptoms of myocardial ischemia or systemic inflammation and wit...
the acute coronary syndrome due to the left main coronary artery (lmca) thrombosis is a clinically rare and catastrophic event. we describe a young man ( smoker, alcoholic, and drug abuser) with a history of recent surgery and typical chest pain who had non-occlusive lmca thrombosis in coronary angiography. the thrombosis was successfully treated with two 180 µ/kg intracoronary boluses of ept...
The coronary vasculature has been traditionally divided into three functional groups: large conductance vessels visible on coronary angiography, which offer little resistance to blood flow; small resistance vessels ranging in size from about 250 to 10 μm in diameter; and veins. Although it has been taught that arterioles (precapillary vessels < 50 μm) account for most of the coronary resistance...
We report the case of a 42-year-old female referred to our institution for an incidental diagnosis of an aortic aneurysm. Multislice 64-CT angiography showed a giant aneurysm of the Valsalva sinus, which extended to all three coronary arteries, and multiple aneurysms along the entire length of the coronaryarteries (Panels A–C ). The Valsalva sinus aneurysm was eccentric, more pronounced near th...
Sinus of valsalva aneurysm is a rare condition arising from any of the three aortic sinuses. Among them, an aneurysm arising from the left coronary sinus is the rarest. Most of these cases were earlier diagnosed using echocardiography and conventional angiography. But with the availability of advanced imaging modalities like 64 slice cardiac CT and MR modalities, this condition can be accuratel...
AIMS The aim of our study was to investigate the accuracy of 64-slice computed tomography (CT) for assessing haemodynamically significant stenoses of coronary arteries. METHODS AND RESULTS CT angiography was performed in 67 patients (50 male, 17 female; mean age 60.1+/-10.5 years) with suspected coronary artery disease and compared with invasive coronary angiography. All vessels > or =1.5 mm ...
A 30-year-old female had an acute myocardial infarction complicated by congestive heart failure. Angiography demonstrated an aneurysm in the area of the left aortic sinus. The aneurysm compressed and displaced the main trunk of the left coronary artery and the proximal portion of the left anterior descending artery. This aneurysm was considered to be the cause of the infarction. Aortic valve re...
OBJECTIVES This study was designed to evaluate whether the absence of coronary calcium could rule out >or=50% coronary stenosis or the need for revascularization. BACKGROUND The latest American Heart Association guidelines suggest that a calcium score (CS) of zero might exclude the need for coronary angiography among symptomatic patients. METHODS A substudy was made of the CORE64 (Coronary ...
Background & Aims: Mortality risk of cardiovascular disease in patients with End Stage Renal Disease (ESRD) is more than general population. Hence, if it isnot regarded, it will result in reduced survival and death in ESRD patients especially who are renal transplant candidates. Aim of the present study was the evaluation of the frequency and pattern of CAD in ESRD patients with candidates ...
A 45-year-old man had a history of myocardial infarction at one month prior to admission. Coronary angiography revealed a dilated fistula originating from the left anterior descending coronary artery to the pulmonary artery. Two orifices of the draining artery were closed through pulmonary arteriotomy. Ligation of the fistulous vessels was performed at three places to ensure complete closure of...
