title: Delayed aortic regurgitation caused by a right coronary stent protruding into the aorta.
abstract: Aortic valve perforation is an extremely rare complication after percutaneous coronary intervention. The case is presented of a 49-year-old male with aortic valve regurgitation secondary to the intra-aortic protrusion of a right coronary stent. The patient had undergone an apparently successful rescue percutaneous transluminal coronary angioplasty with a drug-eluting stent following failed fibrinolysis, but one month later was readmitted for acute pulmonary edema. Further investigations demonstrated new-onset aortic regurgitation. Medical stabilization was achieved and an elective aortic valve replacement and coronary revascularization performed. Intraoperatively, the stent was found to be partially deployed within the aortic lumen, causing perforation to the non-coronary cusp.
