Despite this, dissemination into widespread routine clinical practice has been slow, largely restricted to large academic centers and urban settings. The reasons of this are multifactorial, but one of the most impactful of these reasons is undeniably reimbursement. Currently, there is marked discrepancy between the costs of performing cardiac CT and the renumeration provided for this. Until this is addressed, cardiac CT will not reach its potential for the benefit of patients. It is for this reason that the SCCT continues to dedicate significant efforts to represent the need of the cardiology and radiology communities in bringing about changes in policy and billing. Significant momentum has been gained in recent years with the engagement of both congress and Medicare in moving towards a system of payment that recognizes the time and expertise required to acquire high quality cardiac CT.

However, cardiac conduction abnormalities remain a frequent complication after TAVR ranging from relative benign interventriculair conduction delays to prognostically relevant left bundle branch block and complete atrio-ventricular (AV) block requiring permanent pacemaker implantation (PPI). Although clinical, procedural and electrocardiographic factors have been identified as predictors of this complication, there is a need for advanced strategies to control the burden of conduction defects particularly as TAVR shifts towards younger populations. This state of the art review highlights the value of ECG-synchronized computed tomographic angiography (CTA) evaluation of the aortic root to better understand and manage conduction problems post-TAVR. An update on CTA derived anatomic features related to conduction issues is provided and complemented with computational framework modelling.

This review summarizes the latest research progress on the complex relationship between FFR-CT, plaque characteristics, and hemodynamics, closely linking plaque volume, composition, and distribution with the clinical significance of coronary artery stenosis. It is hoped that these research findings will provide valuable guidance for clinicians, promoting the application of CT in the non-invasive detection of vulnerable plaques, thereby more effectively preventing and managing coronary artery disease.
