ARTERIAL HYPEROXIA AND MORTALITY IN PATIENTS UNDERGOING VENOARTERIAL EXTRACORPOREAL MEMBRANE OXYGENATION.

Background: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) can easily lead to supranormal oxygenation. The impact of hyperoxygenation beyond the early VA-ECMO support phase is unexplored. We sought to investigate its association with short- and long-term mortality.

Transcatheter pulmonary valve implantation in patients with right ventricular outflow tract dysfunction: early and mid-term results.

Objective: The aim of this study was to determine early and long-term results after transcatheter pulmonary valve implantation (TPVI) performed with the use of Medtronic Melody and Edwards Sapien valves in patients with full conduit or patched right ventricular outflow tract (RVOT) dysfunction.

Methods And Results: The study comprised 40 consecutive patients (full conduit, n = 25; RVOT patch, n = 15) who underwent TPVI between December 2008 and April 2012. TPVI was successfully performed in 37 patients (92.

Percutaneous Edwards SAPIEN(™) valve implantation for significant pulmonary regurgitation after previous surgical repair with a right ventricular outflow patch.

Background: Current indications for percutaneous pulmonary valve implantation (PPVI) are limited to patients who had their outflow tracts repaired with the use of a "full" condui-homograft. Patients after a patch repair are believed to have an unfavorable anatomy for PPVI.

Objectives: To evaluate a novel use of Edwards SAPIEN(TM) valve for percutaneous treatment of moderate and severe pulmonary regurgitation after tetralogy of Fallot (TF) repair with a right ventricular outflow (RVOT) patch.
