Introduction The study aimed to retrospectively evaluate the early patient outcome and left ventricular function after mitral valve replacement with a tilting disc valve and total preservation. Patients and methods This retrospective observational study includes patients who underwent mitral valve replacement using a tilting disc valve with total preservation of mitral valvular and subvalvular apparatus from July 2021 to August 2022 at a single center. Results The data were reviewed retrospectively for age, sex, comorbidities, operating time, aortic cross-clamp time, cardiopulmonary bypass time, preoperative and postoperative left ventricular ejection fraction, mean gradient across the mitral valve, left ventricular diameter, left atrial size, atrial fibrillation, complications, mortality, and early patient outcome. Echocardiographic and clinical data were compared for the preoperative and postoperative periods. A significant difference in the preoperative and postoperative left atrial size, pulmonary arterial pressure, New York Heart Association class, and mean gradient across the mitral valve was found. However, the difference between the preoperative and postoperative ejection fraction and left ventricular diameter in systole and diastole was not significant. Conclusion Early patient outcome after mitral valve replacement with a tilting disc valve and total preservation of mitral valvular apparatus gives good results with minimal morbidity and mortality. Favorable patient outcomes in this study lay to rest any skepticism regarding total preservation while using a tilting disc valve. The technique of total preservation is safe while using a tilting disc valve, and it helps in the preservation of the left ventricular ejection fraction and gives a low gradient across the valve.
引言 本研究旨在回顾性评估使用倾斜碟瓣并完全保留二尖瓣装置进行二尖瓣置换术后的早期患者预后及左心室功能。
患者与方法 这项回顾性观察性研究纳入了2021年7月至2022年8月在单一中心接受使用倾斜碟瓣并完全保留二尖瓣和二尖瓣下装置进行二尖瓣置换术的患者。
结果 对患者的年龄、性别、合并症、手术时间、主动脉阻断时间、体外循环时间、术前和术后左心室射血分数、二尖瓣平均压差、左心室直径、左心房大小、心房颤动、并发症、死亡率及早期患者预后等数据进行回顾性分析。比较术前和术后的超声心动图及临床数据。发现术前和术后左心房大小、肺动脉压、纽约心脏协会心功能分级及二尖瓣平均压差存在显著差异。然而,术前和术后射血分数以及收缩期和舒张期左心室直径的差异不显著。
结论 使用倾斜碟瓣并完全保留二尖瓣装置进行二尖瓣置换术后的早期患者预后良好,发病率和死亡率极低。本研究中良好的患者预后消除了在使用倾斜碟瓣时对完全保留二尖瓣装置的任何疑虑。在使用倾斜碟瓣时,完全保留二尖瓣装置的技术是安全的,有助于保留左心室射血分数,并使瓣膜压差较低。
