| Summary: | Recent advancements in computed tomography have significantly transformed the clinical application of this technique in diagnosing and managing coronary artery disease (CAD). Computed tomography coronary angiography (CTCA) has emerged as a leading non-invasive imaging modality, often serving as the first-line investigation to exclude obstructive CAD in patients with chronic coronary syndrome. Beyond its utility in diagnosing CAD, CTCA has become instrumental in procedural planning for percutaneous coronary intervention (PCI), particularly in complex cases such as left main stem (LMS) interventions, where peri-procedural risks are elevated. This review highlights the evolving role of CTCA in LMS PCI, underscoring its clinical utility in improving procedural precision and, subsequently, patient outcomes. Recent technological advancements, including detailed multiplanar and three-dimensional (3D) reconstructions, CT-derived fractional flow reserve (CTFFR), and the integration of artificial intelligence (AI) algorithms, have expanded the capabilities of CTCA. These innovations allow for comprehensive anatomical and functional assessments, enabling precise plaque morphology, lesion complexity, and bifurcation anatomy evaluations alongside PCI simulations. By offering detailed insights into coronary vasculature and lesion characteristics, CTCA provides critical information for optimising LMS PCI strategies. This review explores the current applications and future potential of CTCA in guiding LMS PCI, highlighting its role in improving procedural planning, risk assessment, and overall management of this challenging patient population. |
