Abstract

Background: Cardiac allograft vasculopathy (CAV) assessment post-heart transplantation (HT) typically relies on invasive coronary angiography (ICA). However, cardiac computed tomography angiography (CCTA) is emerging as a promising alternative due to its potential benefits in economic, safety, and logistical aspects. This study aimed to evaluate the impact of a CCTA program on these aspects in CAV surveillance post-HT.

Methods: A retrospective single-center study was conducted between March 2021 and February 2023, involving HT patients who underwent either CCTA or ICA.

Results: Among 260 patients undergoing CAV surveillance, 115 (44.2%) patients underwent CCTA, and 145 (55.8%) patients underwent ICA. The CCTA group showed incurred lower overall costs (p < 0.0001) and shorter hospitalization times (p < 0.0001) compared to the ICA group. In terms of safety, CCTA surveillance required significantly lower contrast volumes (p < 0.0001) and lower effective doses (p = 0.03).

Conclusion: CCTA emerges as a safe and cost-effective non-invasive alternative for CAV surveillance post-HT, outperforming ICA in terms of safety, logistical aspects, and economic burden.

重新定义 CAV 监视策略：CCTA 与 ICA 的优势。

背景：心脏移植术（HT）后的心脏移植血管病变（CAV）评估通常依赖于有创冠状动脉造影术（ICA）。然而，心脏计算机断层扫描血管造影术（CCTA）因其在经济、安全和后勤方面的潜在优势，正在成为一种有前途的替代方法。本研究旨在评估 CCTA 项目对 HT 后 CAV 监测的上述方面的影响：方法：2021 年 3 月至 2023 年 2 月期间进行了一项回顾性单中心研究，涉及接受 CCTA 或 ICA 的 HT 患者：在接受 CAV 监测的 260 例患者中，115 例（44.2%）接受了 CCTA，145 例（55.8%）接受了 ICA。CCTA 组的总费用较低（P 结论：CCTA 是一种安全的血管造影术：CCTA 在安全性、后勤方面和经济负担方面均优于 ICA，是 HT 后 CAV 监测的一种安全、经济的无创替代方法。
