Repeated Interventions in Aortic Root Surgery

Highlights Reoperations in aortic root surgery are performed with increasing frequency. Such operations are technically difficult to perform and the risk of mortality is significantly higher than in primary operations. Summary Aim. Analyze the results of repeated interventions in aortic root surgery Methods. The study includes 11 patients who underwent repeat surgeries at Sechenov University from 2017 to 2022. Initially, one patient was operated using the Ozaki technique at another clinic. Initially, elderly patients predominantly underwent aortic valve replacement with a biological prosthesis. When the aortic root was narrow (≤ 19 mm), the Ozaki procedure was initially considered. Results. The most frequent indications for aortic root repair were valve dysfunction, infective endocarditis, and thoracic aortic aneurysm. On average, aneurysms of the ascending or aortic arch developed 5–6 years after primary aortic root surgery. The 30-day mortality rate was 9.09% (1/11). Conclusion. The method of choice for infective endocarditis is aortic root prosthesis with a homograft. The surgeon's experience and adherence to certain technical protocols allow to achieve acceptable results of repeated interventions.
