We report the case of an 85-year-old woman with severe aortic stenosis who underwent transcatheter aortic valve replacement with use of the Edwards Sapien(®) valve system. The procedure was complicated by rupture of the valve-deployment balloon, with separation and retention of the nose cone of the RetroFlex 3(®) delivery system in the iliac artery. Our endovascular retrieval of the equipment was successful, and we achieved access-site hemostasis by deploying a covered stent.

The association between aortic valve stenosis and gastrointestinal bleeding, traditionally known as Heyde's syndrome, is the result of a quantitative loss of the highest molecular weight von Willebrand multimers (type 2A von Willebrand syndrome). This results in bleeding from areas of high shear stress such as gastrointestinal angiodysplasias. Correction of this bleeding diathesis after surgical aortic valve replacement has been well described.

Background: High-risk percutaneous coronary interventions (PCI), refractory cardiogenic shock and in-lab cardiac arrest are all associated with significant mortality. Percutaneous left ventricular assist devices (pLVAD) and CPS (cardiopulmonary support) have been used to support such patients. However, the extent to which the use of these devices can improve outcomes in this patient subset is not known.
