To evaluate the influence of Bentall procedure on left ventricular function and condition on long-term follow-up.
Seventy-three consecutive patients who underwent an aortic root and ascending aorta replacement with composite valve button Bentall or flanged Bentall technique, from January 2007 to November 2018, were included in this retrospective study.
Postoperative left ventricular ejection fraction significantly increased (52.14±11.38 vs. 56.79±11.36; P=0.041), left ventricular end-systolic diameter significantly reduced (38.25±9.31 mm vs. 34.17±9.15 mm; P=0.027), left ventricular end-diastolic diameter significantly reduced (56.42±9.72 mm vs. 51.58±9.03 mm; P=0.01), and left atrial diameter significantly reduced (45.33±12.77 mm vs. 39.25±12.41 mm; P=0.01), compared to preoperative values. Our long-term survival results are comparable with previous studies in which survival rates in 5 years and 10 years were 83.5% and 69.8%, respectively. In comparing patients according to their New York Heart Association (NYHA) functional class, it was shown that their postoperative functional capacity was improved during the follow-up period (2.1±0.56 vs. 1.2±0.42; P=0.001).
The Bentall procedure significantly improved the left ventricular systolic function and condition and decreased the left ventricular end-systolic and end-diastolic diameters and the left atrial diameter on long-term follow-up, based on the transthoracic echocardiography. Bentall procedure can be performed with acceptable mortality and morbidity rates on long-term follow-up.
评估Bentall手术对左心室功能的影响以及长期随访情况。
本回顾性研究纳入了2007年1月至2018年11月期间连续73例行主动脉根部和升主动脉置换术，采用复合瓣膜纽扣式Bentall或带法兰Bentall技术的患者。
与术前相比，术后左心室射血分数显著增加（52.14±11.38对56.79±11.36；P = 0.041），左心室收缩末期内径显著减小（38.25±9.31mm对34.17±9.15mm；P = 0.027），左心室舒张末期内径显著减小（56.42±9.72mm对51.58±9.03mm；P = 0.01），左心房内径显著减小（45.33±12.77mm对39.25±12.41mm；P = 0.01）。我们的长期生存结果与先前研究相当，其中5年和10年生存率分别为83.5%和69.8%。根据纽约心脏协会（NYHA）心功能分级比较患者，结果显示随访期间其术后心功能得到改善（2.1±0.56对1.2±0.42；P = 0.001）。
基于经胸超声心动图，Bentall手术在长期随访中显著改善了左心室收缩功能和状况，减小了左心室收缩末期和舒张末期内径以及左心房内径。Bentall手术在长期随访中可实现可接受的死亡率和发病率。
