Total occlusion of right coronary artery, proximal to the major right ventricular branches can result in inferior wall myocardial infarction and right ventricular infarction. The catheter used in this case is a transradial Tiger catheter. The contrast reflux into the aorta is also seen. The full right coronary artery with a mild lesion distally is shown below for comparison. In this case the catheter used is a trans femoral Judkins right coronary catheter. RCA: right coronary artery; PDA: posterior descending coronary artery.
