Role of coronary computed tomography angiography to optimise percutaneous coronary intervention outcomes
### Learning objectives: Coronary CT angiography (CTA) is recommended as the first-line diagnostic evaluation for patients presenting with chest pain.1 As a result, a significant proportion of patients referred to the catheterisation laboratory now undergo coronary CTA assessment before the invasive procedure. This approach has been shown to reduce the frequency of major procedure-related complications.2 Nonetheless, coronary CTA is primarily used as a trigger for deciding to perform an invasive angiogram. Despite the undeniable value of coronary CTA in providing anatomical information, its role in guiding revascularisation procedures is often underutilised. The systematic utilisation of coronary CTA in the field of interventional cardiology is hindered by the limited familiarity of interventional cardiologists with CT imaging. However, for readers who are well-versed in invasive angiography and intravascular imaging, grasping the fundamentals of coronary CTA is relatively straightforw
