摘　　要：目的:通过对TAVR患者进行随访,了解术前肺动脉高压对于术后左心室逆向重构的影响。方法与结果:该研究包括2017年9月至2020年12月期间于青岛大学附属医院接受TAVR的主动脉狭窄患者资料。按术前有无肺动脉收缩压(PASP)值将患者分为PH组与n-PH组,并对两组患者TAVR术后左心室逆向重构及相关因素进行对比分析。共纳入67例经导管主动脉瓣置入术前测量PASP的患者,PH组在基线时表现为较高的欧洲评分及较重的二尖瓣返流;两组患者术后仅表现为PH组的住院时间较长。死亡率及不良事件发生率无统计学意义。两组患者术后的左心质量分数及相对室壁厚度均在1年内有明显的改善。其中,PH组在术后3个月内改善明显,但两组患者左心仍未逆转至正常水平。结论:患者接受TAVR治疗后,随着时间的推移左心室发生明显的逆向重构。术前合并有肺动脉高压的患者在术后逆向重构程度弱于无肺动脉高压患者。术前有无肺动脉高压,其术后短期生存率与死亡率无明显差异。Objective: To investigate the effect of preoperative pulmonary arterial hypertension on postoperative left ventricular reverse remodeling by following up patients with TAVR. Methods &Results: Data of patients with aortic stenosis who underwent TAVR at the Affiliated Hospital of Qingdao University between September 2017 and December 2020 were included in this study. Patients were divided into PH group and n-PH group according to the preoperative value of pulmonary artery systolic pressure (PASP), and left ventricular reverse remodeling and related factors after TAVR in the two groups were compared and analyzed. A total of 67 patients with preoperative PASP were included. The PH group had a higher European score and heavier mitral regurgitation at baseline. Patients in both groups showed only a longer postoperative hospital stay in the PH group. The mortality and adverse events were not statistically significant. The left ventricular mass fraction and relative ventricular wall thickness were significantly improved in 2 groups within 1 year. Among them, the PH group improved significantly within 3 months after surgery, but the left heart of patients in both groups did not reverse to normal level. Conclusion: After TAVR treatment, there is significant reverse remodeling of the left ventricle over time. The degree of reverse remodeling in patients with preoperative pulmonary hypertension is weaker than that in patients without. There was no significant difference in short-term survival and mortality between patients with or without preoperative pulmonary hypertension.
