Why the study?
Imaging, particularly strain assessment, may aid in classifying pre- and post-capillary pulmonary hypertension and help resolve ambiguous hemodynamics.
Does combined CMR left atrial volumetric and deformation assessment accurately distinguish post- from pre-capillary pulmonary hypertension compared to TTE?
Does combined CMR left atrial volumetric and deformation assessment accurately distinguish post- from pre-capillary pulmonary hypertension compared to TTE?
CMR volumetric and deformation assessment of the left atrium provides highly accurate differentiation between post- and pre-capillary pulmonary hypertension, outperforming TTE.
No takes yet. Share an insight, caveat, or question.
CMR left atrial assessment shows high accuracy distinguishing PH subtypes; leaves open whether it can guide catheterization decisions without prospective validation.
Leong et al. (2022) studied this question.
