Abstract
Percutaneous coronary intervention in patients with dextrocardia presents several challenges due to abnormal location of the heart, mirror image pattern of aortic arch and its branches, and abnormal coronary origin and orientation. The challenges involve appropriate choice of vascular access, guiding catheters, engagement technique, acquisition and interpretation of radiological orientation of coronary anatomy, and appropriate radiological angles and views. We report a patient with dextrocardia and situs inversus who presented with acute ST segment elevation myocardial infarction and was successfully treated with trans-radial primary percutaneous coronary intervention using “double inversion technique.” We also emphasize that left radial artery approach may be technically preferred to right radial artery approach due to mirror image aortic arch branching pattern.<Learning objective: 1. Percutaneous coronary intervention in patients with dextrocardia presents several challenges due to abnormal location of the heart, mirror image pattern of aortic arch and its branches, and abnormal coronary origin and orientation. 2. These challenges can be overcome by “double inversion technique,” which allows the operator to interpret coronary anatomy and perform intervention as in levocardia.>
