Abstract:
Transcatheter pulmonary valve implantation (TPVI) within a failed bioprosthetic valve is safe and effective Coronary artery compression is a potential risk, requiring careful preimplantation balloon dilation testing Prestenting is required for TPVI in stentless conduits Improvements in right ventricular volume, pressure, pulmonary stenosis, and regurgitation can be maintained in the intermediate term Long-term risk for Melody valve endocarditis and valve dysfunction necessitates careful monitoring.

Mitral Stenosis I: Introduction
Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
