Hemodynamic Follow-Up in Adult Patients with Pulmonary Hypertension Associated with Atrial Septal Defect after Partial Closure

We evaluated the hemodynamic statuses of patients after partial closure of atrial septal defects with fenestration due to pulmonary hypertension. Seventeen adult patients underwent partial atrial septal defect closure and follow-up cardiac catheterization. We analyzed hemodynamic data and clinical parameters before and after closure. The median age at closure was 29 years old. The baseline Qp/Qs was 1.9 ± 0.6. The median interval from the operation to the cardiac catheterization was 27 months. The CT ratio decreased from 0.55 ± 0.07 to 0.48 ± 0.06 (p
