Transcatheter aortic valve replacement (TAVR) is performed to treat aortic stenosis and is increasingly being utilised in the low-to-intermediate-risk population. Currently, attention has shifted towards long-term outcomes, complications and lifelong maintenance of the bioprosthesis. Some patients with TAVR in-situ may develop significant coronary artery disease over time requiring invasive coronary angiography, which may be problematic with the TAVR bioprosthesis in close proximity to the coronary ostia. In addition, younger patients may require a second transcatheter heart valve (THV) to ‘replace’ their in-situ THV because of gradual structural valve degeneration. Implantation of a second THV carries a risk of coronary obstruction, thereby requiring comprehensive pre-procedural planning.
Unlike in the pre-TAVR period, cardiac CT angiography in the post-TAVR period is not well established. However, post-TAVR cardiac CT is being increasingly utilised to evaluate mechanisms for structural valve degeneration and complications, including leaflet thrombosis. Post-TAVR CT is also expected to have a significant role in risk-stratifying and planning future invasive procedures including coronary angiography and valve-in-valve interventions. Overall, there is emerging evidence for post-TAVR CT to be eventually incorporated into long-term TAVR monitoring and lifelong planning.

Background
Coronary CT angiography (CCTA) is well-established for diagnosis and stratification of coronary artery disease (CAD). Its usefulness in guiding percutaneous coronary interventions (PCI) and stent sizing is unknown.
Methods
This is a sub-analysis of the Precise Percutaneous Coronary Intervention Plan (P3) study (NCT03782688). We analyzed 65 vessels with matched CCTA and pre-PCI optical coherence tomography (OCT) assessment. The CCTA-guided stent size was defined by the mean distal reference lumen diameter rounded up to the nearest stent diameter. The OCT lumen-guided stent size was the mean distal reference lumen diameter rounded to the closest stent diameter. The agreement on stent diameters was determined with Kappa statistics, Passing–Bablok regression analysis, and the Bland-Altman method.
Results
The distal reference lumen diameter by CCTA and OCT were 2.75 ± 0.53 mm and 2.72 ± 0.55 mm (mean difference 0.06, limits of agreement −0.7 to 0.82). There were no proportional or systematic differences (coefficient A 1.06, 95% CI 0.84 to 1.3 and coefficient B −0.22, 95% CI -0.83 to 0.36) between methods. The agreement between the CCTA and OCT stent size was substantial (Cohen's weighted Kappa 0.74, 95% CI 0.64 to 0.85). Compared to OCT stent diameter, CCTA stent size was concordant in 52.3% of the cases; CCTA overestimated stent size in 20.0% and underestimated in 27.7%.
Conclusion
CCTA accurately assessed the reference vessel diameter used for stent sizing. CCTA-based stent sizing showed a substantial agreement with OCT. CCTA allows for PCI planning and may aid in selecting stent diameter.
背景：冠状动脉 CT 血管造影（CCTA）在冠状动脉疾病（CAD）的诊断和分层方面已得到广泛认可。但它在指导经皮冠状动脉介入治疗（PCI）和支架选型方面的作用尚不清楚：这是精确经皮冠状动脉介入计划（P3）研究（NCT03782688）的一项子分析。我们分析了 65 条血管，其 CCTA 和 PCI 前光学相干断层扫描 (OCT) 评估结果相匹配。CCTA 引导下的支架大小由平均远端参考管腔直径定义，四舍五入至最接近的支架直径。OCT 管腔引导下的支架尺寸是平均远端参考管腔直径四舍五入至最接近的支架直径。支架直径的一致性通过 Kappa 统计、Passing-Bablok 回归分析和 Bland-Altman 法来确定：结果：CCTA 和 OCT 检测的远端参考管腔直径分别为 2.75 ± 0.53 mm 和 2.72 ± 0.55 mm（平均差异为 0.06，一致度为-0.7 至 0.82）。两种方法之间没有比例或系统性差异（系数 A 1.06，95% CI 0.84 至 1.3；系数 B -0.22，95% CI -0.83至 0.36）。CCTA 和 OCT 支架大小之间的一致性非常高（Cohen's 加权 Kappa 0.74，95% CI 0.64 至 0.85）。与 OCT 支架直径相比，52.3% 的病例的 CCTA 支架大小一致；20.0% 的病例 CCTA 高估了支架大小，27.7% 的病例低估了支架大小：结论：CCTA能准确评估用于支架大小确定的参考血管直径。结论：CCTA 能准确评估用于支架大小确定的参考血管直径，基于 CCTA 的支架大小确定结果与 OCT 非常一致。CCTA可用于PCI规划，并有助于选择支架直径。
