Transfemoral approach is the standard access-route for transcatheter aortic valve replacement (TAVR). However, alternative approaches are needed in a number of patients and accesses such as transapical (TA) TAVR or transcervical (TC) are used. We aimed to compare clinical and echocardiographic outcomes after TA-TAVR or TC-TAVR.
All patients who underwent TA- and TC-TAVR for severe aortic stenosis in our institution between 2008 and 2020 were retrospectively included. End points included 30-day all-cause mortality, procedural complications (according to the Valve Academic Research Consortium-2 criteria), procedure duration, intensive care unit (ICU) length of stay (LOS) and overall hospital LOS. For 30-day all-cause mortality, we furthermore used a Cox proportional-hazards model to adjust for significant between-group differences in baseline characteristics as well as difference in year of intervention.
TAVR was performed in 176 patients, using a TA approach (n = 127) or a TC approach (n = 49). Baseline clinical and echocardiographic characteristics were comparable between the 2 groups, except age and peripheral artery disease. All-cause 30-day mortality rates were not significantly different (8.5% in the TA group vs 2.3% in the TC group, P = 0.124). TC approach was associated with significantly shorter procedure duration {71.0 [interquartile range (IQR) 52.5-101.0] vs 93 [IQR 80.0-120.0] min, P < 0.001}, shorter ICU LOS [0.0 (IQR 0.0-0.0) vs 1.0 (IQR 1.0-3.0) days, P < 0.001] and shorter hospital LOS [7.0 (IQR 5.0-9.5) vs 14.0 (IQR 10.0-22.0) days, P < 0.001].
The TC approach may be a good first-choice alternative in case of contraindications to transfemoral-TAVR.
经股动脉入路是经导管主动脉瓣置换术(TAVR)的标准入路。然而,在许多患者中需要替代方法,例如经心尖(TA)TAVR 或经颈(TC)TAVR。我们旨在比较 TA-TAVR 或 TC-TAVR 后的临床和超声心动图结果。
回顾性纳入 2008 年至 2020 年期间我院因严重主动脉瓣狭窄行 TA-TAVR 和 TC-TAVR 的所有患者。终点包括 30 天全因死亡率、手术并发症(根据 Valve Academic Research Consortium-2 标准)、手术时间、重症监护病房(ICU)住院时间(LOS)和总住院 LOS。对于 30 天全因死亡率,我们还使用 Cox 比例风险模型来调整组间基线特征和干预年份的差异。
共对 176 例患者进行了 TAVR,其中 127 例采用 TA 入路,49 例采用 TC 入路。两组患者的基线临床和超声心动图特征无显著差异,除年龄和外周动脉疾病外。两组 30 天全因死亡率无显著差异(TA 组 8.5%,TC 组 2.3%,P=0.124)。TC 入路与手术时间显著缩短相关{71.0[四分位距(IQR)52.5-101.0] vs 93[IQR 80.0-120.0]min,P<0.001},ICU 住院时间更短[0.0(IQR 0.0-0.0)vs 1.0(IQR 1.0-3.0)d,P<0.001],住院时间更短[7.0(IQR 5.0-9.5)vs 14.0(IQR 10.0-22.0)d,P<0.001]。
在经股动脉 TAVR 禁忌的情况下,TC 入路可能是一种很好的首选替代方法。
