Abstract:
Despite the growing evidence with emerging transcatheter tricuspid valve repair therapies, the experience with transcatheter tricuspid valve replacement remains sparse. We describe a case of severe tricuspid regurgitation in a 79-year-old patient deemed unsuitable for isolated tricuspid valve surgery, successfully treated with a 40-mm self-expandable NaviGate (NaviGate Cardiac Structures, Inc, Lake Forest, CA) valved stent via a transatrial approach, with excellent result and hemodynamic performance at 4 months.

Initiation of Translation
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...

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...
