Percutaneous Treatment of Proximal Migration of an Alterra Prestent.

ABSTRACT: Treatment of native right ventricular outflow tract (RVOT) dysfunction with predominant pulmonary regurgitation has become a catheter-based procedure since the introduction of the RVOT reducer devices such as the Alterra prestent (Edwards Lifesciences). These devices have potential complications. One such complication is the migration or embolization of the stent. Herein, we present 2 cases of patients with native RVOT dysfunction who underwent the implantation of the Alterra prestent complicated by proximal migration of the stent, which was managed by placement of a second Alterra prestent in 1 case and repositioning of the prestent in the second case.
