Bentall procedure for reoperation in the small aortic root or annulus / 中国胸心血管外科临床杂志

ABSTRACT

@#Objective 聽 聽To investigate and evaluate the safety and efficacy of Bentall operation in the reoperation of patients with small aortic root or annulus. Methods 聽 聽Bentall procedure was performed in 24 patients with small aortic root or annulus in our hospital from September 2014 to December 2019. There were 18 males and 6 females with a mean age of 31-68 (45.70卤15.27) years. All patients had undergone a previous replacement of the aortic valve including 20 patients receiving valve replacement, 2 patients aortic root replacement with a valved conduit and 2 patients bioprothesis replacement. Results 聽 聽There was no early death in hospital and one death during the 30-day postoperative period. Re-thoracotomy due to bleeding was necessary in only 2 patients and no bleeding was related to the proximal anastomosis of the conduit. One patient performed pacemaker implantation for heart block after the procedure. The mean sizes of implanted aortic valve prosthesis were 22.75卤1.78 mm. A mean gradient across the aortic valve prostheses in the postoperative echocardiographic examination was 11.17卤2.24 mm Hg. Conclusion 聽 聽Bentall procedure is safe and allows a larger size of prosthesis implantation in patients with small aortic annulus or root after previous aortic valve or complete root replacement, resulting in good postoperative hemodynamic characteristics and short-term clinical results.
