Abstract

An isolated single coronary artery is rare but often associated with other congenital cardiac malformations and myocardial ischemia. We report a rare case of right ventricular myocardial infarction due to total occlusion of the right coronary artery originating from the distal left circumflex artery.

  Fig. 1 Electrocardiography showing ST-segment elevation in the inferior leads (II, III, aVF) (A), and ST-segment elevation in the reverse precordial leads (V3R, V4R, V5R, V6R) (B).

  Fig. 2 Coronary angiography showing total occlusion at the distal left circumflex artery.

• 

  Fig. 3 Coronary angiography after stent insertion showed no residual stenosis with good distal flow and extended the distal left circumflex artery belong to course of the right coronary artery.

  Fig. 4 Contrast enhanced 320-slice multi-detector cardiac computed tomography. Note the absence of the right coronary artery ostium at right coronary cusp (A) and the extended distal portion of the left circumflex artery with patent stent (B).
