Anomalous origin of right coronary artery: magnetic resonance angiography and viability study.

Objective: To detect origin and course and to evaluate viability in patients with anomalous RCA.

Design: 3D coronary MR angiography and viability study using gadolinium-enhanced magnetic resonance imaging (Gd-MRI) was performed.

Setting: A tertiary hospital center.

Coronary flow evaluation by TIMI frame count and magnetic resonance flow velocity in patients with coronary artery ectasia.

Purpose: Coronary artery ectasia (CAE) is defined as a dilatation of an arterial segment to a diameter at least 1.5 times that of the adjacent artery. It is characterized by slow flow, predisposing to thrombosis.
