Abstract

Besides multiple dehiscences or paravalvular aortic regurgitation due to endocarditis, there are still many cases where the cause cannot be found. Re-operation of these cases is still challenging. We present a new transmural aortic suturing technique that addresses this problem. Results: From August 2022 to May 2023, there were five cases of severe paravalvular aortic not due to endocarditis in which the new technique was applied. The median follow-up time was 6 months (4-13 months) with positive results: no death, no paravalvular regurgitation, no atrioventricular block, and no reoperation. Conclusion: Our technique of transmural aortic suturing with Dacron strip enhancement gives excellent short-term results. Longer follow-up for these cases is also needed to determine the long-term effectiveness of this new technique
