Insights
The Bentall procedure significantly enhances left ventricular function and reduces cardiac dimensions long-term. This aortic surgery offers improved patient functional capacity with acceptable survival rates.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery
- Aortic Surgery
Background:
- Aortic root and ascending aorta diseases often necessitate complex surgical interventions.
- The Bentall procedure is a standard technique for replacing these aortic segments.
- Evaluating the long-term impact on cardiac function is crucial for patient outcomes.
Purpose of the Study:
- To assess the long-term effects of the Bentall procedure on left ventricular function.
- To evaluate changes in cardiac dimensions and patient functional capacity post-surgery.
Main Methods:
- Retrospective study of 73 patients undergoing aortic root and ascending aorta replacement.
- Utilized composite valve button or flanged Bentall techniques.
- Transthoracic echocardiography used for long-term follow-up assessment.
Main Results:
- Significant improvement in left ventricular ejection fraction (P=0.041).
- Significant reduction in left ventricular end-systolic (P=0.027), end-diastolic (P=0.01), and left atrial diameters (P=0.01).
- Improved New York Heart Association functional class (P=0.001) and comparable long-term survival rates (5-year: 83.5%, 10-year: 69.8%).
Conclusions:
- The Bentall procedure significantly improves left ventricular systolic function and cardiac dimensions long-term.
- The procedure demonstrates acceptable mortality and morbidity rates for aortic root and ascending aorta replacement.
Objective:
To evaluate the influence of Bentall procedure on left ventricular function and condition on long-term follow-up.
Methods:
Seventy-three consecutive patients who underwent an aortic root and ascending aorta replacement with composite valve button Bentall or flanged Bentall technique, from January 2007 to November 2018, were included in this retrospective study.
Results:
Postoperative left ventricular ejection fraction significantly increased (52.14±11.38 vs. 56.79±11.36; P=0.041), left ventricular end-systolic diameter significantly reduced (38.25±9.31 mm vs. 34.17±9.15 mm; P=0.027), left ventricular end-diastolic diameter significantly reduced (56.42±9.72 mm vs. 51.58±9.03 mm; P=0.01), and left atrial diameter significantly reduced (45.33±12.77 mm vs. 39.25±12.41 mm; P=0.01), compared to preoperative values. Our long-term survival results are comparable with previous studies in which survival rates in 5 years and 10 years were 83.5% and 69.8%, respectively. In comparing patients according to their New York Heart Association (NYHA) functional class, it was shown that their postoperative functional capacity was improved during the follow-up period (2.1±0.56 vs. 1.2±0.42; P=0.001).
Conclusion:
The Bentall procedure significantly improved the left ventricular systolic function and condition and decreased the left ventricular end-systolic and end-diastolic diameters and the left atrial diameter on long-term follow-up, based on the transthoracic echocardiography. Bentall procedure can be performed with acceptable mortality and morbidity rates on long-term follow-up.
