Background: Complications associated with treating aortic root aneurysm using the conventional Bentall technique necessitated the development of modified techniques to improve patient outcomes. This study aimed to describe a modified Bentall technique for aortic root replacement and report the middle- and long-term follow-up outcomes.
Methods: Eighty-eight patients (9 with Marfan syndrome), including 69 males (78.4%) and 19 females (21.6%), underwent aortic root replacement using the modified Bentall technique from 2011 to 2020 at our hospital. The patients' mean age was 43.4±11.7 years (range, 20–71 years). Data were collected on surgical time, aortic clamping time, cardiopulmonary bypass time, and computed tomography angiography before discharge.
Results: The patients' in-hospital mortality was 2.27%, with one case of multiple organ dysfunction syndrome and one of arrhythmia. The mean aortic cross-clamp time and cardiopulmonary bypass time were 120.9±27.1 mins and 159.2±37.9 mins, respectively. The follow-up rate was 94.2% (81/86) for 55±23 months (range, 6–120). Follow-up mortality occurred in three cases (3.7%), including one death due to a traffic accident, one death due to cerebral hemorrhage, and one sudden death of unknown reasons. No patients required aortic root re-operation during follow-up. The survival rate was 98.8%, 95.9%, and 95.9% after 48, 96, and 120 months, respectively.
Conclusions: Our modified Bentall technique can be performed easily and safely, with excellent middle- and long-term outcomes. Our technique can be an effective alternative method in aortic root aneurysm treatment.
