The rescue snared wire technique for challenging transcatheter pulmonary valve implantation: a case series of two patients

Abstract

Background Transcatheter pulmonary valve implantation (TPVI) is an effective treatment for right ventricular outflow tract (RVOT) dysfunction. Patients affected by congenital heart disease requiring TPVI may have difficult anatomies, thus making the intervention technically demanding. Case summary We report a case series of two patients affected by RVOT dysfunction. Both the cases were characterized by difficulty to advance the valve over the wire, which was successfully overcome by the application of the snared wire technique (SWT) to TPVI. Discussion Various technical pitfalls and tips have been described to facilitate the delivery of the transcatheter Edwards Sapien valve in the pulmonary position. The SWT described by the authors may be a helpful tool to gain supportiveness and stability of the guidewire during the procedure.

Holography-guided procedural planning for modifying Venus P-valve implantation technique in patients with left pulmonary artery stents: a case-series

“…Nowadays, transcatheter pulmonary valve implantation (TPVI) represents a valid therapeutic option ( 7 ). TPVI is minimally invasive compared to surgical pulmonary valve implantation and has been reported as a feasible procedure with successful implantation rates greater than 95% ( 5 , 7 ). However, it can present challenges due to the anatomical variability of the RVOT and pulmonary artery (PA) ( 5 , 8 ).…”

“…TPVI is minimally invasive compared to surgical pulmonary valve implantation and has been reported as a feasible procedure with successful implantation rates greater than 95% ( 5 , 7 ). However, it can present challenges due to the anatomical variability of the RVOT and pulmonary artery (PA) ( 5 , 8 ). Due to the variability in patient anatomy, TPVI requires 3-dimentional (3D) and personalised procedural planning.…”
