Why the study?
Does right atrial function contribute more to total right heart function in patients with pulmonary arterial hypertension compared to normal controls?
Does right atrial function contribute more to total right heart function in patients with pulmonary arterial hypertension compared to normal controls?
Right atrial function accounts for a significantly greater proportion of total right heart function in patients with pulmonary arterial hypertension compared to normal subjects, highlighting the importance of atrial compensation.
No takes yet. Share an insight, caveat, or question.
Right atrial compensation may predominate in PAH right heart function; extends TAPSE decomposition but leaves open prospective validation.
Sivak et al. (2016) studied this question.
