Reliability of Contrast Echocardiography to Rule Out Pulmonary Arteriovenous Malformations and Avoid <scp>CT</scp> Irradiation in Pediatric Patients with Hereditary Hemorrhagic Telangiectasia

Abstract

A low-grade classification (Barzilai 0 or 1) could presumably exclude the presence of PAVMs and allow CT irradiation to be avoided in children and adolescents. The screening algorithm using TTCE first would allow more than 40% of the pediatric patients screened for PAVMs to be spared the radiation dose of CT.
