Echocardiographic features of pre- and postcapillary pulmonary hypertension with a focus on the right ventricle in dogs

Abstract

ABSTRACT: Pulmonary hypertension (PH) in dogs is a syndrome that can occur secondary to several causes, including left heart disease (postcapillary) and chronic respiratory disease (precapillary). This study evaluates morphological and functional consequences in the right ventricle (RV) of dogs with pre- and postcapillary PH through echocardiography, and also considers the severity of PH (mild, moderate or severe). Echocardiography was performed on 66 dogs of various breeds and weights (age >3 years old) wh…
