Rationale: Unlike invasive coronary angiography and echocardiography, cardiac computed tomography (CCT) and cardiac magnetic resonance (CMR) imaging allow a coronary artery fistula (CAF) comprehensive evaluation focusing on both coronary and myocardial findings.
Patient concerns: We present the case of an asymptomatic patient suspected for CAF and referred to our structure for cardiovascular evaluation.
Diagnosis: The patient was diagnosed a CAF without coronary artery disease on the basis of CMR and CCT.
Interventions: The patient underwent an invasive coronary angiography after which the medical staff decided not to surgically treat the CAF. Therefore, a conservative treatment was chosen with strict temporal monitoring.
Outcomes: After less than 1 year follow-up, the patient presented stable conditions without complaints.
Lessons: Multimodal non-invasive imaging has a key role in patient assessment for disease diagnosis providing better understanding for prognosis and treatment.
