BACKGROUND In this retrospective study, we compared the results from 2 pulmonary valve augmentation techniques in patients undergoing surgical repair of tetralogy of Fallot. METHODS Between 2015 and 2018, 18 patients had anterior pulmonary valve repair at our institution, and 26 patients had both anterior and posterior pulmonary valve repair. RESULTS Patients ranged from 6 months to 30 years of age. The median follow-up period was 8 months in the anterior augmentation group and 5 months in the anterior and posterior augmentation group. Postoperative echocardiograms indicated that only 2 patients (11%) in the anterior augmentation group had moderate or severe pulmonary insufficiency, compared with no patients in the anterior and posterior augmentation group. At follow-up, pulmonary insufficiency was seen in 3 patients (17%) in the anterior augmentation group and no patients in the anterior and posterior augmentation group. CONCLUSION Reconstruction of the native pulmonary valve accompanied by pulmonary cusp augmentation can decrease or even circumvent postoperative pulmonary insufficiency. Both anterior augmentation and anterior and posterior augmentation techniques are easily applied; however, we believe that the anterior and posterior augmentation technique is superior in terms of early postoperative and follow-up pulmonary insufficiency outcomes.
