Clinical Decision-Making and Imaging-Guided Follow-Up Strategies in Spontaneous Coronary Artery Dissection

Year: 2026

Type: article

Abstract: Spontaneous coronary artery dissection (SCAD) is an important non-atherosclerotic cause of acute coronary syndrome, predominantly affecting younger women without traditional cardiovascular risk factors. In hemodynamically stable patients, accumulating evidence supports a conservative management strategy owing to the high rate of spontaneous vessel healing, while technically challenging invasive interventions should be reserved for selected high-risk cases. Despite growing evidence regarding acute management, recurrent SCAD and other adverse cardiovascular events have been reported during follow-up, underscoring the need for surveillance. However, optimal strategies for post-acute follow-up and for assessing the appropriateness of treatment decisions remain insufficiently established. This review focuses on clinical decision-making in the management of SCAD, with particular emphasis on follow-up assessment. We summarize the existing evidence regarding indications for conservative versus invasive treatment and discuss the clinical rationale for longitudinal imaging surveillance. Special attention is given to the role of non-invasive follow-up using coronary computed tomography angiography, including confirmation of vessel healing, evaluation of residual intramural hematoma, and assessment of distal coronary flow. Given the heterogeneity of SCAD and the risk of recurrence, individualized treatment decisions and structured follow-up strategies are essential to optimize management, avoid unnecessary invasive procedures, and support care and risk stratification in patients with SCAD.
