A child undergoing routine transcatheter patent arterial duct closure developed severe transient ischemic changes in the electrocardiogram (Pardee waves) while the aortic retention skirt of the Amplatzer™ Duct Occluder was pulled against the duct orifice. The occluder was then released, and the delivery system was pulled back to inferior caval vein which led to electrocardiogram normalisation. Aortic root angiography showed a single coronary artery originating from the right sinus of Valsalva with the left coronary stem wedged behind the posterior aspect of the right ventricular outflow tract. We believe that the left coronary artery was compressed while applying tension on the occluder delivery system.
