METHODS: Our echocardiography database was reviewed for patients with a diagnosis of dTGA status post-atrial switch operation treated with pulmonary vasodilator therapy (monotherapy or combination).
RESULTS: Six patients (2 male, 4 female) were identified from 104 patients (67% male). Mean age at atrial switch was 22.1 months; mean age of PAH diagnosis was 29.3 years. Functional class improved from a baseline mean of 3.3 to 1.8 on treatment (p=0.001). No adverse events were associated with treatment. 3 of 4 patients initially referred for heart-lung transplant no longer require transplantation.
CONCLUSIONS: PAH is a late complication of the atrial switch procedure for dTGA, affecting 5.7% of our dTGA atrial switch population, with a higher incidence in female patients. In this cohort, pulmonary arterial vasodilator therapy was well tolerated and improved functional status.
