background: the incidence of stroke after coronary artery bypass grafting (cabg) is between 0.9% and 6.7%, which significantly increases in-hospital and out-hospital costs. this study was designed to evaluate the prevalence of significant carotid stenosis and its risk factors in cabg. methods: in total, 2044 consecutive patients undergoing elective cabg were investigated through a pre-operative...

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...

Background. We tested the prevalence and impact of HCV seropositivity among Egyptian patients referred for coronary angiography. Subjects and Methods. This cross-sectional study was conducted in Zagazig University hospitals including 509 patients scheduled for elective coronary angiography between June 2013 and June 2014. By taking full history on admission, laboratory workup including HCV Ab, ...

the anomalous origin of the right coronary artery (rca) as a branch from the left anterior descending artery (lad) is a very rare variation of the single coronary artery anomaly. the anomalous vessel arises from the proximal or midportion of the lad and courses anterior to the pulmonary artery trunk in most instances. in this case report, a 61-year-old woman is introduced who underwent coronary...

BACKGROUND Coronary artery fistula and single coronary artery are two different rare congenital anomalies. The cases with co-existed the two anomalies are more rare. To the best of our knowledge with literature review, the coronary artery fistula between single right coronary artery and right pulmonary artery has not been previously reported. CASE PRESENTATION In the present article, we repor...

Coronary artery anomalies are rare, and their incidence varies from 0.6% to 1.3%. Conventional angiography is a commonly used modality for the assessment of coronary artery anomalies, but it may not identify and define the anatomy of anomalous arteries due to the complexity of the course and three-dimensional orientation of the arteries. We present a rare case of duplicated right coronary arter...

Coronary artery anomalies are rare, with their incidence varying from 1 to 5%. Angiography is a commonly used modality for the assessment of coronary artery anomalies. Based on previous reports, a majority of coronary artery anomalies are of origin or distribution, with separate ostia of the left anterior descending artery and left circumflex artery. Coronary artery anomalies may cause myocardi...

MRI of subjects with silent intracranial damages may provide more evidence than CT. Our objectives were to determine the prevalence of silent MRI lesions in patients with coronary artery disease. The study included 72 consecutive patients with angiographically proven coronary artery disease and 26 age and sex matched controls with normal coronary angiography. All subjects were evaluated for cor...
