Abstract:
Percutaneous pulmonary valve implantation is increasingly adopted as an alternative procedure to surgery in dysfunctional homograft, and in patients with "native" or wide right ventricle outflow tract dysfunction. Pre-stenting is mandatory in this category of patients for many reasons, one of which is to create an adequate landing zone for the bioprosthesis. Here we report on a tricky situation that occurred during pre-stenting, and we describe how we successfully overcame it.

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...
