Coronary anomalies affect a small percentage of the general population. A solitary coronary ostium in the absence of other major congenital anomalies is very rare. We describe a case of a patient, admitted to our cardiology department with an acute myocardial infarction. A coronary angiogram shows a solitary ostium originating from the right sinus of Valsalva with the left anterior descending c...
BACKGROUND Coronary computed tomography angiography (CCTA) is helpful in making a precise noninvasive evaluation of coronary anatomy, allowing concomitant evaluation of other cardiac structures. The aim of this study was to determine the prevalence of coronary artery variations detected by 64-slice multi detector CT. MATERIALS AND METHODS The results of ECG-gated CCTA in 726 consecutive patie...
Left bundle-branch block (LBBB) was found to be associated with an unusually short left main coronary artery in 11 of 12 patients studied by selective coronary arteriography. The average length of the left coronary artery in this group of 12 patients with LBBB was 4.5 + 1.7 mm as compared to 12.8 + 0.8 mm in a control group. Four of the 12 had evidence of ischemic heart disease, one had mild ao...
DURING the initial phases in the development of open-heart surgery, problems related to the perfusion procedure were common causes of morbidity and mortality. With improved perfusion technics and increased knowledge of the physiology of cardiopulmonary bypass, such problems have become less frequent. Now that the perfusion procedure itself is accomplished with considerable safety, the surgical ...
background: the presence of significant carotid stenosis in coronary artery bypass grafting (cabg) patients increases the risk of either transient ischemic attack or stroke. however, there is a dearth of data on the risk for patients with unilateral total occlusion of the carotid artery. we herein report our results of cardiac surgery in patients with unilateral total occlusion of the carotid a...
This article describes coronary artery bypass grafting by Avlliath Jay akrishnan et al. one of the most common reason for coronary artery bypass grafting is narrowing coronary arteries because of atherosclerosis. Atherosclerosis causes chest pain (angina pectoris), myocardial infarction and sudden death. The aim of coronary artery bypass grafting is to release pain, prevention of myocardial i...
Anomalous left coronary artery from pulmonary artery (ALCAPA) is a rare congenital heart disease that affects one in every 300 000 live births and accounts for 0.24–0.46% of cases of congenital heart disease [1]. Over the last few decades, four different operative procedures have been recommended as treatment for ALCAPA: the simple ligation of ALCAPA, coronary artery bypass grafting, channel re...
BACKGROUND As coronary computed tomography angiography (CCTA) has emerged as a non-invasive alternative for evaluation of coronary anatomy with a lower referral threshold than invasive coronary angiography (ICA), the prevalence of coronary anomalies in CCTA may more closely reflect the true prevalence in the general population. Morphological features of coronary anomalies can be evaluated more ...
