Comparison of atrial volumes, unmatched and matched for PVR. Tukey box plot showing comparison of atrial volumes among unmatched and matched subgroups of pre‐capillary pulmonary hypertension. All volumes are indexed for body surface area. (A–D) Right atrial volumes. (E–H) Left atrial volumes: left column, maximal volumes; right column, minimal volumes. (A, B, E, and F) Comparison among groups when unmatched for PVR. (C, D, G, and H) Comparison between groups when matched for PVR. RAVmax, right atrial maximal volume; RAVmin, right atrial minimal volume; IPAH/FPAH, idiopathic or familial pulmonary arterial hypertension; SSc‐PAH, pulmonary arterial hypertension associated with systemic sclerosis; CTD‐PAH, pulmonary arterial hypertension associated with connective tissue disorders; CTEPH, chronic thrombo‐embolic pulmonary hypertension; LAVmax, left atrial maximal volume; LAVmin, left atrial minimal volume; PVR, pulmonary vascular resistance.
