摘要

目的

探讨重度主动脉瓣狭窄(aortic valve stenosis

AS)患者经导管主动脉瓣置换术(transcatheter aortic valve replacement

TAVR)后早期左室舒张末期内径(left ventricular end-diastolic diameter

LVEDD)变化及该变化对TAVR预后的影响。

方法

采用回顾性队列研究。纳入2017年12月至2021年12月在陆军军医大学第二附属医院接受TAVR治疗的重度AS患者113例。依据术后超声心动图结果将术后LVEDD较术前改善≥1.8 mm定义为早期LVEDD改善

将患者分为有改善组和无改善组。患者通过门诊或电话完成术后1年随访并收集患者心脏超声、心电图及手术相关并发症等数据。研究终点为主要不良心血管事件(major adverse cardiovascular events

MACE)

包括1年的全因死亡、心肌梗死或心绞痛、心力衰竭再入院的复合终点。

结果

患者年龄54~87(71.2±6.5)岁

Abstract

Objective

To investigate the early changes of left ventricular end-diastolic diameter (LVEDD) in patients with severe aortic valve stenosis (AS) after transcatheter aortic valve replacement (TAVR) and the effect of the changes on the prognosis of TAVR.

Methods

A single-center retrospective cohort study was performed on 113 severe AS patients undergoing TAVR treatment in our hospital from December 2017 to December 2021.When the improvement of postoperative to preoperative LVEDD ≥1.8 mm was defined as early LVEDD improvement by echocardiography

the patients were divided into improvement group and non-improvement group.After the patients were followed up in 1 year after TAVR through clinic or telephone visits

their clinical data on cardiac ultrasound

electrocardiogram

and surgery-related complications were collected.The endpoints were major adverse cardiovascular events (MACE)

including 1-year all-cause mortality

myocardial infarction or angina

and heart failure-related hospitalization.

Results

The average age of the patients was 71.2±6.5 years

and 59(52.2%) of them were female.The postoperative (4 d after TAVR on average) LVEDD was 48.9±6.5 mm

significantly shorter than that preoperati

vely (50.7±7.3 mm

0.001).There were 53 patients obtaining early improvement of LVEDD before discharge

accounting for 46.9% of the discharged patients.Univariate Cox regression analysis found that preoperative diabetes (

: 2.635

95%

: 1.013~6.858

=0.047) and postoperative pacemaker implantation (

: 3.518

95%

: 1.336~9.263

=0.011) were risk factors for MACE at 1 year

and early improvement of LVEDD was a protective factor (

: 0.176

95%

: 0.052~0.601

=0.006).Multivariate Cox analysis indicated that early LVEDD improvement was still an independent protective factor for MACE at 1 year (

: 0.231

95%

: 0.062~0.857

=0.029).

Conclusion

LVEDD can be improved to various degrees in the early stage after TAVR

and the cumulative risk of developing MACE at 1 year in patients with early improvement of LVEDD is lower than that of patients without improvement.
