Abstract
Background: The aging congenital heart disease (CHD) population is prone to develop a variety of sequelae, including pulmonary arterial hypertension (PAH). Previous prevalence reports have a high degree of variability, with an overrepresentation of tertiary centers. We aimed to report robust prevalence estimates of PAH in adult CHD patients.
Methods and Results: We performed a cross-sectional analysis to determine prevalence of PAH in adults with CHD using the population-based Dutch Congenital Corvitia (CONCOR) registry. Of 12 624 adults with CHD alive in 2011, 5 487 (44%) had an initial diagnosis of systemic-to-pulmonary shunt and were thereby at risk for developing PAH. From these patients, a random sample of 1 814 subjects was obtained, mean age 40±15 years, and 135 PAH cases were observed. Total PAH prevalence in patients born with a systemic-to-pulmonary shunt was 7.4%. A remarkable high number of patients had PAH after corrective cardiac surgery, with a prevalence of 5.7%. PAH prevalence increases with age, from 2.5% under 30 years until 35% in the oldest patients of the study cohort. In the entire CHD population the PAH prevalence was 3.2%. Based on an overall prevalence of CHD in the adult population of 3000 per million, we can assume a prevalence of PAH-CHD of 100 per million inhabitants.
Conclusion: Prevalence of PAH in CHD patients is 3.2%, and 100 per million in the general adult population. Especially in patients after corrective cardiac surgery and the elderly, physicians should be aware of PAH-CHD, to provide optimal therapeutical and clinical care.
