Purpose : Cone reconstruction is effective surgical treatment option for Ebstein anomaly. Cardiac Magnetic resonance imaging (MRI) is effective modality to evaluate right ventricular volume and function. We evaluated the data on cardiac MRI about right ventricular function and volume compared preoperative data to postoperative data in patients with Ebstein anomaly.
Methods : Between January 2014 and June 2019, 18 patients with Ebstein anomaly underwent cone reconstruction. 11 patients were children (61.1%) and 7 patients were adults (38.9%). Of them, seven patients were excluded because there was no MRI data. Mean age at operation was 20.3±18.2 years (range, 0.6-60 years). There were 7 patients (63.6%) with New York Heart Association (NYHA) class I-II function and 4 (36.4%) with class III function. Echocardiographic studies and magnetic resonance imaging before and after the repair was evaluated.
Results : The mean follow-up duration was 1.8±1.6 years. All patients decreased less than mild TR on postoperative transthoracic echocardiography. Right ventricular ejection fraction(RVEF) and Left ventricular ejection fraction(LVEF) were slightly increased on cardiac MRI, but there were no statistically significant difference (p=0.35 and p=0.56, respectively). The mean postoperative right ventricular end-diastolic dimension index(RVEDVi) and right ventricular end-systolic dimension index(RVESVi) were 86.8±24.0ml/m2 and 53.7±20.1ml/m2, respectively, showing rather decreases compared to preoperative measures (p<0.05 for both).
Conclusion : There was no significant change in ventricular ejection fraction after cone reconstruction, but each volume index of RV was decreased and septal movement was improved on MRI. Cone reconstruction appeared to be a good effect in the RV volume reduction and clinical outcomes.
