Purpose : Atrial septal defect (ASD) is the most common congenital heart disease. However, the details of cardiac chamber remodeling after surgery are not well known and is an important issue that should be analyzed to understand long-term outcomes.
Methods : Between November 2017 and January 2019, cardiac magnetic resonance imaging was performed three times, preoperatively, at the 1-month and 1-year postoperative follow-up. Cardiac chamber volume, valve regurgitation volume, and ejection fraction were measured as functions of time.
Results : Thirteen patients (10 males and 3 females) were included. The median age at surgery was 51.4 years. The preoperative median Qp/Qs was 2.3. The preoperative mean right ventricle end-diastolic volume index (RVEDVi) and right ventricle end-systolic volume index (RVESVi) were significantly decreased at the postoperative follow-up at 1 month (P = < 0.001, P = 0.001, respectively). The decrease in the RVEDVi (P = 0.085) and RVESVi (P = 0.023) continued until the postoperative follow-up at 1 year, although the rate of decrease was reduced. The TR was also decreased at the postoperative follow-up at 1 month (P = 0.022), and the TR decrease continued with a reduced rate (P = 0.129). Although the RVEDVi and RVESVi improved after ASD closure, the RV volume parameters were still larger than the LV volume parameters at the 1-year follow-up {RVEDVi vs LVEDVi (P = 0.016), RVESVi vs LVESVi (P = 0.001)}.
Conclusion : Cardiac remodeling after ASD closure is common and mainly occurs in the early postoperative period. However, complete normalization does not occur.
