Con cierta frecuencia escuchamos que un amigo iba corriendo, como todos los días desde hace 10 años y de repente cae muerto en la calle con un infarto del corazón. ¿Sabía usted que la causa más frecuente de este tipo de muerte, son anomalías congénitas de las arterias coronarias?
El sumario que le enviamos trata una las causas más frecuentes de muerte, debido a que la Arteria Coronaria Derecha (ACD) tiene un origen anómalo, originándose en la Arteria Coronaria Izquierda (ACI) y como cursa en el pequeño espacio inter-arterial entre la aorta ascendente y la arteria pulmonar, con el ejercicio este espacio se reduce y se produce compresión de la arteria coronaria derecha, siendo el riesgo mayor cuando el curso de la ACD es ALTO.
Esta anomalía se ha encontrado como causa de muerte entre un 4 a 15% en jóvenes corredores.
El artículo es una revisión de 22,925 Arteriogramas Coronarios por Tomografía Helicoidal realizados en la Universidad de Yonsei, Korea del Sur.
En los países industrializados se recomienda una evaluación cardio-vascular previa a los atletas, específicamente los de alto rendimiento.

Anomalous Origin of the Right Coronary Artery from the Left Coronary Sinus with an Interarterial Course: Subtypes and Clinical Importance
Radiology 2012; 262: 108
Purpose
To classify anomalous origins of the right coronary artery (RCA) from the left coronary sinus (AORL) with an interarterial course into two subtypes and to evaluate the clinical importance of each.
Materials and Methods
Institutional review board approval was obtained for this retrospective study, and informed consent was waived. Through a retrospective review of 22 925 consecutive cardiac computed tomographic (CT) scans, 124 cases of AORL with an interarterial course were identified. These anomalies were classified into two subtypes according to the location of the anomalous RCA ostium: high interarterial course (between the aorta and the pulmonary artery) and low interarterial course (between the aorta and the right ventricular outflow tract). The clinical records were evaluated, and differences in prevalence of typical angina and major adverse cardiac events (MACEs) between the subtypes were analyzed through the χ2 contingency tables or Fisher exact test.
Results
After excluding patients with combined cardiac disease, 87 patients (51 [59%] men, 36 [41%] women; mean age, 56.0 years) were enrolled. Of the 87 patients, 53 had a high interarterial course and 34 had a low interarterial course. A significant difference in the prevalence of typical angina (high [43%] vs low [6%],P = .012) was observed between the two subtypes. For patients with a high interarterial course, the odds ratio for typical angina was 12.3 (95% confidence interval: 2.7, 56.6), and the odds ratio for MACE was 6.3 (95% confidence interval: 1.3, 29.7
Conclusion
The prevalence of typical angina and that of MACE were significantly higher in patients with a high interarterial course than in those with a low interarterial course. © RSNA, 2011
