There was no difference in right ventricular (RV) size, mean pulmonary arterial pressure (mPAP) and pulmonary vascular resistance (PVR) (p>0.05). After adjusting for age, sex, body surface area, WHO functional class, mPAP and PVR, a smaller left atrial area and smaller main pulmonary artery diameter were associated with a BMPR2 mutation.Conclusion: In this preliminary analysis of the UK National IPAH cohort, we have observed that BMPR2 carriers had smaller pulmonary arteries and smaller left atria. Whether this reflects differences in RV afterload and left ventricle preload requires further investigation.FootnotesCite this article as: European Respiratory Journal 2019; 54: Suppl. 63, PA5454.This is an ERS International Congress abstract.
