The long-term results of modified aortic valve replacement in patients with aortic root and ascending aortic aneurysm

The OBJECTIVE of the study was to analyze the long-term results of the use of modified aortic valve reimplantation in patients with aortic root and ascending aortic aneurysms.
METHODS AND MATERIALS. From 2011 to 2024, 79 patients underwent surgery for ascending aortic aneurysm with aortic valve (AV) insufficiency using modified reimplantation of aortic valve (MRAV). The control groups were: 80 patients with Bentall procedure and 51 patients who underwent .
RESULTS. The average age of patients in the MRAV group was 61 years (53-68). The average diameter of the aorta in the study group was 55 mm, in the Bentall group 54 mm and in the David group 60 mm. The average diameter of the AV fibrous ring in the study group was 24.7 before surgery and 22.5 after surgery, compared with the Bentall group, where the average diameter of the AV was 25.1 before surgery (p=0.189) and 21.9 after surgery (p=0.120). The average diameter of the AV in the David group was 23.1 before surgery (p=0.603) and 22.0 after surgery (p=0.213). In the long–term period, freedom from aortic regurgitation after 5 years was 79% for the David group and 92% for the MRAV group. After 10 years, this indicator decreased to 51.8% in the David group and 79.7% in the MRAV group. The survival rate of the compared groups after 5 years was 88.6% in the MRAV group with a slight decrease to 83% after 10 years; in the David group – 86.1% with a significant decrease to 54.4% after 10 years. In the Bentall group, the survival rate after 5 years was 88.5%. After 10 years, this indicator in this group had not changed.
CONCLUSION. This study shows that the proposed technique can be performed with good immediate and long-term results. The technique is relatively simple and reproducible.
