Conclusion:
Recurrent pericarditis along with constrictive physiology may occur in
adolescent patients with prior ASD repair after a prolonged symptom free
interval. Therefore, adolescents with repaired congenital heart defects
should be carefully screened for development of PCIS. Management can be
challenging and often requires advanced imaging (CMR) to guide
appropriate therapy. Treatment may necessitate addition of biologics to
anti-inflammatory therapy or further escalation to pericardiectomy in
refractory cases. Further research is needed to identify at-risk
patients and design preventive strategies.
