Insights
The button Bentall operation for ascending aortic aneurysm and severe aortic valve insufficiency shows safe short-term results, with no in-hospital mortality observed in this patient cohort. Further studies are needed to confirm these findings.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Aortic Surgery
Background:
- Ascending aortic aneurysms often coexist with aortic valve insufficiency, necessitating complex surgical repair.
- The button Bentall operation is a standard procedure for complex aortic root and ascending aorta pathologies.
Purpose of the Study:
- To evaluate the early clinical outcomes of the button Bentall operation.
- To assess the safety and efficacy of this procedure in patients with ascending aortic aneurysm and severe aortic valve insufficiency.
Main Methods:
- Retrospective analysis of 21 patients undergoing elective button Bentall operation between 2020 and 2023.
- Exclusion criteria included emergency operations, type 1 aortic dissection, pregnancy, and other specific comorbidities.
Main Results:
- All 21 patients had severe aortic valve insufficiency, with 47.6% presenting with bicuspid aortic valves.
- No in-hospital mortality was recorded; however, 19% required early revision surgery for hemorrhage.
- Mean cross-clamp and cardiopulmonary bypass times were 87.33±16.77 min and 118.81±19.88 min, respectively.
Conclusions:
- The button Bentall operation demonstrated a safe profile with no early in-hospital mortality in this series.
- The procedure appears to be a viable surgical option for ascending aortic aneurysms combined with severe aortic valve insufficiency, based on short-term results.
Objective:
This study to analyze the early-term results of patients who underwent button Bentall operation.
Methods:
Twenty-one patients (12 males, 9 females; 50.67±13.79 years) who underwent an elective button Bentall operation between 2020 and 2023 were included in the study. Patients who were pregnant or breastfeeding, those younger than 18 years of age, who underwent emergency operation, who had type 1 aortic dissection, and who underwent additional valve operations other than aortic valve, infective endocarditis, and reoperations were excluded.
Results:
Ten (47.6%) patients had bicuspid aortic valve structure, and all patients had severe aortic valve insufficiency. Four (19%) patients required early revision surgery due to hemorrhage. No mortality was observed during the hospitalization period. The mean cross-clamp time was 87.33±16.77 min, and the mean cardiopulmonary bypass time was 118.81±19.88 min.
Conclusion:
In our study, early in-hospital mortality was not observed and we believe that this difference may be due to the small number of patients. Nevertheless, button Bentall operation for ascending aortic aneurysm and valve insufficiency appears to be a safe surgical treatment method with short-term results.
