[In-hospital and mid-term results of aortic root remodeling and aortic valve annuloplasty in patients with aortic root aneurysm and no severe aortic valve disease]. / Gospital'nye i sredneotdalennye rezul'taty remodelirovaniya kornya aorty s annuloplastikoi aortal'nogo klapana u bol'nykh s anevrizmoi kornya aorty bez vyrazhennogo organicheskogo porazheniya aortal'nogo klapana.

OBJECTIVE: To analyze early and mid-term results of aortic root remodeling with aortic valve annuloplasty in patients with aortic root aneurysm and no severe aortic valve disease. MATERIAL AND METHODS: There were 33 patients with connective tissue dysplasia, aneurysm of aortic root and/or ascending aorta and aortic regurgitation between September 2019 and December 2022. All patients underwent aortic root remodeling with aortic valve annuloplasty. RESULTS: Mean time of cardiopulmonary bypass was 138.5±21.5 min, aortic clamping - 115.3±20.5 min. According to postoperative transthoracic echocardiography, mild aortic regurgitation was observed in 28 patients, 5 patients had moderate regurgitation. Postoperative follow-up period varied from 3 months to 2 years. There was no in-hospital mortality or significant cardiovascular complications. Two-year freedom from moderate-to-severe aortic regurgitation was 93.9%, overall survival - 100%. CONCLUSION: Aortic root remodeling is characterized by favorable hemodynamic efficiency and low complication rate.

OBJECTIVE: Analysis of the outcomes after aortic root remodeling with aortic valve annuloplasty in patients with aortic root aneurysm and no severe aortic valve disease. MATERIAL AND METHODS: 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. RESULTS: 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%. CONCLUSION: 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.
