科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
- 干预心脏病学 干预心脏病学
背景情况:
- 计算机断层扫描血管造影 (CTA) 越来越受青,而不是过食管回声心脏造影 (TEE),用于在左心房附属物关闭 (LAAC) 过程中进行手术前规划.
- 然而,对于WATCHMANTM传统和FLX设备,支持基于CTA的规划的长期结果数据仍然有限.
研究的目的:

- 评估CTA在预测LAAC所需设备大小方面的准确性.
主要方法:
- 在5年内对231名连续接受LAAC的患者进行了前性分析,并进行了CTA手术前规划.
- 评估了包括程序成功,不良事件,设备尺寸准确性,长期死亡率和栓塞事件率在内的关键结果.
- 研究人员分析了长达5年的随访数据,并根据CHA2DS2-Vasc和HAS-BLED得分调整了预测中风和主要出血率.
主要成果:
- 手术成功率高达99.1%,CTA在93.5%的患者中准确预测了植入物大小.
- 术前并发症发生率很低,为2.2%.
- 在368天的中位随访期 (总计377.04个患者年),全因死亡率为每100个患者年13.52,1,2,3年死亡率分别为12.7%,20.9%和29.2%. 1,2,3年心血管事件发生率分别为2.1%,6.6%和10.5%.

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
