Mid-Term Results of Aortic Valve Sparing Root Surgery Operations

Abstract

Introduction: In this study, we retrospectively analyzed the mid-term outcomes of patients who underwent aortic valve-sparing root replacement (VSARR). Patients and Methods: Ninety-six patients operated on due to annuloaortic ectasia in our clinic between 2012 and 2016 were examined. Twenty-four patients who underwent VSARR were included in the study. They were evaluated using echocardiography and computed tomography in terms of mortality and reoperation according to their preoperative demographic characteristics, aortic regurgitation (AR), and annular dilatation levels. Results: The early mortality rate was 12.5% (n= 3) and was associated with emergency operation and total arch replacement. The mean follow-up was 33.00 ± 9.53 months. The early mortality rate was 12.5% (n= 3) and was associated with emergency surgery and total arch replacement (p= 0.035, p< 0.05). The mean followup was 33.00 ± 9.53 months. None of the patients required reoperation. While postoperative AR was seen in one patient with Takayasu’s arteritis (n= 1, 4.16%), it was not observed in the patients with Marfan syndrome or bicuspid aortic valve disease. Postoperative AR and preoperative AR were related (p= 0.012, p< 0.05), but preoperative annulus diameter was not (p= 0.296, p> 0.05). There was no difference in valve durability between the use of Dacron and Valsalva grafts (p= 0.724, p> 0.05). Conclusion: For patients with aortic root aneurysms, elective VSARR is a good surgical option. However, the presence of comorbidities is related to high mortality because it necessitates urgent and complicated surgery for patients with aortic dissection.
