Ventricular adaption remains unclear and could provide a basis for explaining differences in clinical outcomes. The aim of this prospective study was to assess clinical status, haemodynamic profile, and biventricular adaptation to PAH in children with various forms of PAH.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods and results<\/jats:title>\n                  <jats:p>Consecutive patients with IPAH\/HPAH or post-operative PAH were prospectively recruited (n = 64). All patients underwent a comprehensive, protocolized assessment including functional assessment, measurement of brain natriuretic peptide (BNP) levels, invasive measurements, and a cardiac magnetic resonance (CMR) assessment. A cohort of age- and sex-matched healthy subjects served as controls. Patients with post-operative PAH had a better functional class (61.5 vs. 26.3% in Class I\/II, P = 0.02) and a longer 6-min walk distance (320 \u00b1 193 vs. 239 \u00b1 156 m, P = 0.008) than IPAH\/HPAH. While haemodynamic parameters were not significantly different between IPAH\/HPAH and post-operative patients, post-operative patients with PAH presented with higher left ventricular volumes and better right ventricular function compared with patients with IPAH\/HPAH (P &amp;lt; 0.05). On correlation analyses, left ventricular volumetric parameters were highly correlated with BNP and 6-min walk test distance in this population.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Despite comparable haemodynamic profiles, patients with post-operative PAH had less functional limitation than their IPAH\/HPAH counterparts. This is potentially related to the differential biventricular adaptation pattern evident on CMR with better myocardial contractility and higher left ventricular volumes in post-operative patients with PAH, highlighting the importance of ventriculo-ventricular interaction in the setting of PAH.<\/jats:p>\n
