摘要:
目的 于影像学方法分析主动脉根部形态学特征与经导管主动脉瓣置换术(transcatheter aortic valve replacement,TAVR)后新发左束支传导阻滞(new left bundle branch block,new-LBBB)的相关性,找寻这一并发症的危险因素及可靠的定量评价方法。 方法 顾性分析昆明医科大学附属延安医院2023年6月至2024年8月症状性重度主动脉瓣狭窄或关闭不全并行TAVR患者资料,共计65例。根据术后是否出现new-LBBB将样本分为病例组(n = 27)和对照组(n = 38);分析两组患者临床资料、 CT及超声心动图结果的差异。 结果 病例组窦管结合部平均内径及周长、瓣环水平面夹角及经心尖TAVR(transapical transcatheter aortic valve replacement,TA-TAVR)数量大于对照组(P < 0.05),病例组膜部长度、膜部长度与支架置入深度差值小于对照组,差异均有统计学意义(P < 0.05)。 结论 瓣环水平面夹角、支架置入深度与膜部长度的差值及经心尖入路是TAVR术后new-LBBB的独立危险因素。 -

Abstract:Objective To analyze the correlation between the morphological characteristics of aortic root and new left bundle branch block (New-LBBB) after transcatheter aortic valve replacement (TAVR) based on imaging methods, and to find the risk factors for this complication and a reliable quantitative evaluation method. Methods Data of 65 patients with symptomatic severe aortic stenosis or regurgitation and concurrent TAVR at Yan 'an Hospital Affiliated to Kunming Medical University from June 2023 to August 2024 were retrospectively analyzed. According to the presence or absence of new-LBBB, these patients were divided into the case group (27 cases) and control group (38 cases) respectively. Clinical data, CT and echocardiography results were analyzed. Results The mean inner diameter and circumference of the sinus canal junction, the Angle of the annulus and the number of TA-TAVR in the case group were greater than those in the control group, and the membrane length, membrane length and stent insertion depth in new-LBBB group were smaller than those in the control group, and the differences were statistically significant (P < 0.05). Conclusion The angle between the horizontal plane of the valve annulus, the difference between the depth of stent placement and the length of the membrane, and the transapical approach are independent risk factors for new LBBB after TAVR surgery.. -
