AImax, maximal atrial index; AImin, minimal atrial index; CTD‐PAH, patients with pulmonary arterial hypertension associated with connective tissue disease; CTEPH, patients with pulmonary hypertension due to chronic thrombo‐embolism; IPAH/FPAH, patients with idiopathic or familial pulmonary arterial hypertension; LAVmax, left atrial maximal volume; LAVmin, left atrial minimal volume; RAVmax, right atrial maximal volume; RAVmin, right atrial minimal volume; SSc‐PAH, patients with pulmonary arterial hypertension due to systemic sclerosis.
Values are expressed as mean ± SD. All volumes are indexed for body surface area.
