Abstract:
Transcatheter pulmonary valve replacement (TPVR) is a safe and feasible procedure for treating pulmonary stenosis, failed right ventricular conduits, or failed bioprosthetic valves. The medtronic melody valve and the Edwards Sapien XT and S3 valves have been the main prosthetic valves used in TPVR. Using the GORE DrySeal sheath helps valve delivery and facilitates TPVR.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
