Cirurgia de preservação da valva aórtica em idosos com estenose aórticaAortic valve preservation surgery in elderly patients with aortic stenosis Abstract Objective: The aim of this study was to investigate early and late results of the aortic valve preservation surgery (AVPS) through reshaping, decalcification and commissurotomy of the aortic valve (AV) in aortic stenosis (AS) in elderly patients.Methods: Thirty-two patients with isolated AS, older than 65 years-old who underwent aortic valve repair were studied retrospectively at InCor FMUSP. Early and late results and echocardiographic follow-up were investigated. Outpatient follow-up was performed by outpatient record review and interview by phone contact. Actuarial and event-free survival analysis were performed using the Kaplan-Meier method.Results: Four patients (15.4%) presented AV stenosis. Five patients developed moderate heart failure and two developed severe heart failure. Decalcification, commissurotomy and rough-hewing were performed in 28, 20 and 16 patients, respectively. Nine patients presented severe postoperative complications (28.1%). Two hospital deaths due to pneumonia/sepsis and five late deaths had occurred. Postoperative NYHA functional status were 70.5%, 17.6%, 5.8% and 5.8% for functional classes I, II, III and IV, respectively. Actuarial eight-year survival rate was 66.9 ± 12.1%. Eight-year free thromboembolism and endocarditis rate were 90.9 ± 8.7% and 100%, respectively.Conclusion: Aortic valve preservation surgery in elderly with AS presented as a procedure with low morbidity and mortality and presented an eight-year acceptable survival rate and functional class improvement among the studied series of patients.
