Surgical Rescue of Right Ventricular Outflow Tract Stent Malposition With Tricuspid Valve Compromise.

Transcatheter ballon dilation has emerged as a valuable strategy to treat residual or recurrent right ventricular outflow tract (RVOT) obstruction following valve-sparing repair of tetralogy of Fallot (TOF). When balloon dilation is unsuccessful, stent placement in the RVOT may be effective. While uncommon, stent-related complications can occur and contribute to unintended morbidity. We report a case of RVOT stent malposition leading to severe tricuspid regurgitation and ventricular dysrhythmias in a child with recurrent RVOT obstruction following valve-sparing repair of TOF. Surgical management was required and included complete stent removal and bioprosthetic pulmonary valve replacement.
