Change in right atrial minimal volume is a prognostic marker in pulmonary arterial hypertension (PAH)

Background In contrast to the considerable literature on the prognostic value of right ventricular metrics at baseline and follow-up in PAH, the prognostic value of right atrial size and function has been less well studied. The aim of this study was to compare the prognostic value of right atrial length, area and volume measurements in treatment naïve patients with PAH and the impact of treatment. Methods Patients with PAH who...
