Aortic root remodeling and aortic valve annuloplasty in patients with aortic root aneurysm and no severe aortic valve disease

Abstract

Analysis of the outcomes after aortic root remodeling with aortic valve annuloplasty in patients with aortic root aneurysm and no severe aortic valve disease. There were 19 patients with connective tissue dysplasia, aneurysm of aortic root and/or ascending aorta and aortic regurgitation between September 2020 and December 2021. All patients underwent aortic root remodeling with aortic valve annuloplasty. Mean time of cardiopulmonary bypass was 148.7±23.5 min, aortic clamping - 117.3±19.5 min. According to postoperative transthoracic echocardiography, mild aortic regurgitation was observed in 6 patients, 13 patients had no regurgitation. There was no in-hospital mortality or significant cardiovascular complications. Freedom from moderate-to-severe aortic regurgitation after 14 months was 94.7%, overall survival - 100%. Aortic root remodeling is characterized by favorable hemodynamic efficiency and low complication rate. Further accumulation of data with clinical analysis are planned for a more accurate assessment of effectiveness of surgical treatment, determination of predictors of successful reconstruction, development of indications, contraindications and a personalized algorithm for patient selection.
