and their relation to concurrent aging changes. (P < 0.001) in the combined group (0.62 ± 0.18 cm), the right ventricular (RV) pressure overload group (0.60 ± 0.13 cm) and the RV volume overload group (0.53 ± 0.11 cm). Thirty-two patients underwent diagnostic right heart catheterization which revealed a good correlation between the RVWT measured echocardiographically and the right ventricular peak systolic pressure (r = 0.84).Subxiphoid echocardiography was considered to be useful in diagnosing right ventricular hypertrophy in adults.size of the right ventricle, the value of which increases in patients with atrial septal defect or tricuspid insufficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
