Abstract
Atrial septal defect (ASD) typically is asymptomatic in infancy and early childhood and elective defect closure usually is performed at an age between 4 - 6 years. Severe pulmonary hypertension (PHT) complicating an ASD is seen in adulthood and has only occasionally been reported in small children.
A retrospective study was undertaken to evaluate the incidence of severe PHT complicating an isolated ASD and requiring early surgical correction in the fi rst year of life. 355 pediatric patients underwent treatment for an isolated ASD either surgically or by catheter intervention during a 10 year period (1996 - 2006) at two tertiary referral centers. 297 patients had secundum ASD and 58 primum ASD with mild to moderate mitral regurgitation. 8 infants were found with isolated ASD (six with secundum and two with primum ASD) associated with signifi cant PHT, accounting for 2.2% of all ASD patients in our centers. These 8 infants had invasively measured pulmonary artery pressures between 50 and 100% of systemic pressure. Median size of the ASD at the time of surgery was 14mm (7 - 20). They were operated in the fi rst year of life and had complicated postoperative courses requiring specifi c treatment for PHT for up to 16 weeks (median 12) postoperatively. Compared to ASD patients without PHT these infants had prolonged postoperative ICU stay of 5 - 9 days (median 8) and prolonged perioperative overall hospital stay of 8 - 32 days (median 15). Ultimate outcome in all 8 infants was good with persistent normalization of pulmonary pressures during mid-term follow-up of between 8 to 60 months (median 28). All other ASD patients had normal pulmonary pressures and mean age at defect closure was higher being 6.2 years for secundum ASD and 3.2 years for primum ASD.
In conclusion, ASD is rarely associated with signifi cant PHT in infancy but then requires early surgery to normalize the prognosis of the patients.
