Sudden cardiac death (SCD) in athletes is an uncom-mon but dramatic occurrence, with an incidence of 0.6 to 3.6/100,000 per year. SCD is mainly due to malignant ventricular arrhythmias that may occur in case of con-duction re-entry abnormality. While hypertrophic cardio-myopathy is the most common cause of SCD in athletes younger than 35 years, coronary artery disease (CAD) is the predominant aetiology in middle age and older ath-letes. Malignant congenital coronary anomalies are the second most common cause of SCD. Other possible causes of SCD are myocarditis, arrhythmogenic right ventricular cardiomyopathy, dilated cardiomyopathy and less com-mon pathologies – such as myocardial bridging, left ven-tricular non compaction cardiomyopathy, sarcoidosis and valvular disease. The main morphological and functional conditions predisposing to SCD can be present on the imaging armamentarium.

While echocardiography is the primary imaging modality in athletes with and without clinical symptoms, electrocar-diographically (ECG) abnormalities or family history sug-gesting risk for SCD, cardiac magnetic resonance (CMR) has a growing role for the detection of cardiomyopathies and their differentiation from adaptive athlete’s heart. In addi-tion, CMR provides the unique ability to unveil unsuspected focal or diffuse myocardial fibrosis. Lastly, coronary com-puted tomography angiography (CCTA) has become a non-invasive modality with high accuracy to exclude obstructive CAD. CCTA is also a highly accurate tool for visualizing myo-cardial bridging and has been shown to be superior to con-ventional coronary angiography in delineating the origin and the course of congenital coronary anomalies.
