Why the study?
The clinical relevance of pulmonary arterial capacitance index in pediatric PAH, and its relationship with functional capacity and exercise tolerance in CHD, remains unclear.
Does the pulmonary arterial capacitance index (PACi) correlate with disease severity and respond to PAH-specific therapy in children with CHD-associated PAH?
Does the pulmonary arterial capacitance index (PACi) correlate with disease severity and respond to PAH-specific therapy in children with CHD-associated PAH?
In children with CHD-associated PAH, the pulmonary arterial capacitance index is significantly reduced and inversely correlates with pulmonary vascular resistance and mean pulmonary artery pressure.
PACi may mark severity in pediatric CHD-PAH; leaves open its response to therapy and outcome prediction.
