Echocardiography Grading for Pulmonary Arteriovenous Malformation Screening in Children with Hereditary Hemorrhagic Telangiectasia

Transthoracic contrast echocardiography (TTCE) has high sensitivity but low specificity in screening for pulmonary arteriovenous malformations (pAVMs) in children with hereditary hemorrhagic telangiectasia (HHT). Here we describe characteristics of TTCE that might be used to reduce the need for confirmatory computed tomography scans in children with HHT.
