Atresia of the right atrial ostium of the coronary sinus.

A case of asymptomatic congenital occlusion of the ostium of the coronary sinus is described. The myocardial venous drainage was maintained via a persistent left superior vena cava as well via ectatic, widened atrial veins of the dorsal wall of the left atrium. The study shows that complete ostial occlusion of the coronary sinus does not reduce cardiac venous drainage. The view of the literature allows a comparison with the comprehensive classification of coronary sinus anomalies.

Evolution of rescue systems: a comparison between Cologne and Cleveland.

INTRODUCTION: Comparisons of different emergency medical services (EMS) systems often are reduced to simple comparisons between distinct facilities or strategies (e.g., prehospital physician versus paramedic, "scoop and run" versus "stay and play"). METHODS: The EMS systems of similar cities (Cologne and Cleveland) in two different countries (Germany and the United States) are compared. The comparison is seen from the perspective of an evolutionary standpoint that reflects the development of the EMS system in connection with the special environments. Data on rescue times, facilities, and (trauma) outcomes are compared. RESULTS: No statistically significant differences in outcome between the systems were detected. CONCLUSION: Both systems are developed in special environments and are optimized over decades, which explains the similarities in outcome.
