Tissue Doppler Imaging Predicts Adverse Outcome in Children with Idiopathic Pulmonary Arterial Hypertension

Tricuspid Em velocity correlated with NYHA functional class as disease severity and may serve as a useful prognostic marker in children with idiopathic PAH. The present study is the initial report to evaluate TDI velocities against midterm outcome variables in a relatively large pediatric PAH population.
