Abstract

Single right coronary artery with congenital absence of left coronary artery is one of the rarest coronary artery anomalies. Most coronary anomalies are asymptomatic and incidental findings. We report a case of single right coronary artery with congenital absence of left coronary artery detected by coronary CT angiography. Physical examination revealed a well-nourished female with a blood pressure of 130/75 mmHg and a pulse rate of 56 beats per minute. The myocardial enzymes and blood lipid levels showed normal findings. The dynamic electrocardiogram revealed frequent ventricular premature beats. Dual-source CT angiography was performed for evaluation of coronary artery. The imaging showed a very large single coronary artery arising from the right coronary sinus of Valsalva, and demonstrated absence of the left coronary artery. Meanwhile, the findings were confirmed by coronary angiography.
