Abstract

The aim of this work was to propose a preliminary local diagnostic reference levels (DRL) for pediatric interventional cardiology (PIC) procedures in Argentina, for different ranges of age and weight. This work has been conducted in the framework of the “Optimization of Protection in Pediatric Interventional Radiology in Latin America and the Caribbean” (OPRIPALC) program coordinated by the World Health Organization and the Pan American Health Organization in cooperation with the International Atomic Energy Agency to ensuring that radiation exposures of pediatric patients are the minimum necessary during fluoroscopy-guided interventional procedures. The local DRL values presented in this paper by weight group and age group were 7.1 Gy·cm2 (2 (5–15 kg), 18.0 Gy·cm2 (15–30 kg), 15.9 Gy·cm2 (30–50 kg), and 28.2 Gy·cm2 (50–80 kg) and 5.3 Gy·cm2 (2 (1 to 52 (5 to 102 (10 to 16

Abstract

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.
