Study of Coronary Artery Anatomy in Sudan Heart Centre

Abstract

This study is descriptive, retrospective and was carried in Sudan Heart Center on patients seen during the period from Jan ٢٠٠١ to Dec ٢٠٠٣ . The objectives were to study the normal coronary artery anatomy, to determine the incidence of the normal coronary artery variations and anomalies by reading the coronary angiography of patients selected for the study. ٤٢٩ patients who had coronary angiography were included in this study. ٥٥٪ were female and the rest were males. The mean age of the patients was ٥٤٫٣٢ . ٤٠٠ (٩٣%) had normal coronary artery anatomy, ٢٤ (٦٪) had a normal coronary artery variations and ٥ (١٪) had coronary artery anomalies. The right dominant circulation was found in ٧٧٪ of the patients, while ١٥٪ had co dominant and ٨٪ left dominant circulation. The mean mid segment diameter of the LAD was ٣٫٨٣mm, the Cx artery is ٢٫٩٥mm, and the RCA was ٢٫٧١mm. Females mid segment coronary artery diameter is smaller than that of the males.
