Abstract：Objective To analyze the surgical outcomes of patients with severe aortic valve stenosis complicated with severe left ventricular dysfunction.Methods Thirty-nine patients with severe aortic valve stenosis complicated with severe left ventricular dysfunction (left ventricular ejection fraction ≤ 35％) undergoing aortic valve replacement from January 2010 to August 2017 in Beijing Anzhen Hospital,Capital Medical University were enrolled.Surgical records,postoperative and follow-up data were analyzed.Results Mean cardiopulmonary bypass time was (84 ± 44) min;mean aortic clamp time was (68 ± 30) min.Thirty-two mechanical prosthetic valve and 7 biological valve were implanted;the valve type included size 19(5 cases),size 21 (18 cases) and size 23(9 cases).Two patients died of low cardiac output syndrome and 2 patients died of hematogenous infection during perioperative period.Left ventricular ejection fraction after operation was significantly higher than that before operation[(38 ± 6)％ vs (30 ± 7)％] (P ＜ 0.05).The median follow-up time was 49 months (2-92 months).The 1-,3-,5-year survival rate were 87.2％ (34/39),79.5％ (31/39) and 66.7％ (26/39),respectively.Conclusion Surgical operation shows a satisfactory curative effect on severe aortic valve stenosis complicated with severe left ventricular dysfunction.
