Abstract:
Objective To evaluate the clinical effectiveness of valve-sparing aortic root replacement (VSARR) in the treatment of patients with dilated aortic root after operation for tetralogy of Fallot (TOF). Methods A retrospective analysis was conducted on clinical data of TOF patients with aortic root dilation who underwent VSARR in our hospital from 2016 to 2022. Results Finally 14 patients were collected, including 8 males and 6 females, with a median age of 22 years ranging from 12-48 years. Among them, 5 patients had severe aortic valve regurgitation, 4 moderate regurgitation, and 5 mild or no regurgitation. Six patients had sinus of valsalva dilation, and 8 significant dilation of the ascending aorta. One patient had residual shunt due to ventricular septal defect, and 9 severe pulmonary valve regurgitation. The David procedure was performed in 10 patients, Yacoub procedure in 2 patients, and Florida sleeve in 2 patients. There was no perioperative mortality in the group. The median follow-up time was 2.9 years (ranging from 0.4 to 6.0 years). One patient had mild aortic valve regurgitation, and the rest had minimal or no regurgitation. One patient had mild stenosis of the left ventricular outflow tract, and the rest patients had no obvious stenosis. Conclusion VSARR is a satisfactory treatment for aortic root dilation in patients with TOF, with no significant increase in the incidence of left ventricular outflow tract stenosis or aortic regurgitation during mid-term follow-up.
