摘要

简介:在过去十年中,左心房阑尾封堵术(LAAO)已成为心房颤动(AF)患者口服抗凝药的一种成熟替代方案。LARIAT 装置是目前唯一可用于经皮左心房阑尾(LAA)完全闭合的心外膜系统。目的:介绍对接受心外膜 LAAO 治疗的房颤患者的长期疗效(超过 9 年的观察期)。材料与方法:一项前瞻性单中心研究:对121名接受LARIAT系统LAAO手术的患者进行了前瞻性单中心研究。研究记录了血栓栓塞事件、严重出血和死亡率的发生率。对 LAAO 术后血栓栓塞和出血风险的降低进行了量化:平均随访时间为 74.18 个月。平均 CHADS2 评分为 1.9 ± 1.0,CHA2DS2-VAS 评分为 2.8 ± 1.5,HAS-BLED 评分为 2.7 ± 1.0。年平均血栓栓塞事件发生率为 0.7%,估计血栓栓塞风险降低了 75%。大出血并发症的年发生率为 0.8%,估计出血风险降低了 67.9%。年总死亡率为1.2%:结论:采用 LARIAT 装置的心外膜 LAAO 可降低中风和出血风险,从而获得值得称道的长期疗效。

A decade later: long-term results of the first percutaneous epicardial closure of the left atrial appendage using the LARIAT device.

Introduction: Over the past decade, left atrial appendage occlusion (LAAO) has emerged as an established alternative to oral anticoagulation for patients diagnosed with atrial fibrillation (AF). The LARIAT device stands as the sole available epicardial system for complete percutaneous left atrial appendage (LAA) closure.

Aim: To present the extended outcomes (spanning over 9 years of observation) in patients with AF who underwent epicardial LAAO. The presented results constitute the longest observation in world literature.

Material and methods: A prospective, single-center study was conducted on 121 patients undergoing LAAO with the LARIAT system. Incidence of thromboembolic events and severe bleeding and mortality rates were documented. The reduction in the risk of thromboembolism and bleeding after LAAO was quantified.

Results: The mean follow-up duration was 74.18 months. The average CHADS2 score was 1.9 ±1.0, CHA2DS2-VAS score was 2.8 ±1.5, and HAS-BLED score was 2.7 ±1.0. The mean annual thromboembolic event rate was 0.7%, resulting in a 75% reduction in estimated thromboembolic risk. The annual occurrence of major bleeding complications was 0.8%, leading to a 67.9% reduction in estimated bleeding risk. The overall annual mortality rate was 1.2%.

Conclusions: Epicardial LAAO employing the LARIAT device yields commendable long-term outcomes by reducing stroke and bleeding risk.
