Transcatheter pulmonary valve replacement has become an attractive alternative to surgical approach in patients with dysfunctional right ventricular outflow tract. However, in certain cases, an unfavorable anatomy might complicate optimal valve deployment and stability. Several techniques have been described to reshape the landing zone and allow proper implantation of the transcatheter valve. Among them, the hybrid approach has gained attention as an interesting method for off-pump pulmonary valve replacement in patients with dilated right ventricular outflow tract. But to date, there is no standardized method to resize and reshape the landing zone for the stented valve. Here, we describe a reproducible method based on simple geometric rules to allow adequate remodeling of the main pulmonary artery to the desired dimensions in a single attempt, followed by perventricular implantation of a Venus P-valve.
