Validation of cardiac index measured by four‐dimensional cardiac magnetic resonance flow against the invasively measured cardiac index in patients with pulmonary hypertension
Abstract:The purpose of this study was to validate cardiac index (CI) measured noninvasively by four‐dimensional (4D) and two‐dimensional (2D) cardiovascular magnetic resonance (CMR) flows against the invasively measured CI by right heart catheterization (RHC) in patients with pulmonary hypertension (PH). Thirty patients with PH (mean age: 32 ± 10 years) were included. 4D and 2D flow measured CI within 24 h from RHC measured CI invasively. Qualitative analysis of 4D pulmonary flow (vortex presence and eccentricity of f… Show more
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.
