A 47-year-old man with severe radiation-induced aortic stenosis was rejected for cardiac surgery because of porcelain aorta. We successfully implanted an Edwards SAPIEN valve (Edwards Lifesciences, Irvine, CA), but the patient was readmitted 3 weeks later for heart failure with a continuous murmur on auscultation. Echocardiography showed a small defect between the aorta and the infundibulum of the right ventricle, which was also confirmed with aortography and computed tomography. Medical therapy was optimized; however, he died unexpectedly a few weeks later. We concluded that irradiated tissues are particularly fragile and require specific attention during transcatheter aortic valve implantation. Furthermore, this case suggests that a more aggressive closure should have been applied.
