| dc.description | The coronary sinus has lately assumed an important role in the cardiologic clinic once it has been widely used in invasive procedures of the heart. Commonly, it is used during the electrodes implants for the epimiocardic monitoring of the cardiac rhythm, through a biventricular pace maker. These invasive procedures are not possible in hearts with an atresic coronary sinus ostium. In the presence of this anomaly, another may occur: the development of the "Marchal" vein which is a remaining of the left superior vena cava (LSVC). This happens so that the venous blood from the heart can drain into the right atrium, by a communication between the LSVC and the left brachiocephalic vein. The presence of a LSVC brings difficulties when performing an invasive procedure in order to access the right atrium through the superior vena cava, usually done in the cardiologic clinic. Moreover, the LSVC crossing over the left atrium is vulnerable to cardiovascular surgical interventions, confirmed by clinical reports. In the present study, 400 formalin fixed hearts from male cadavers, aged between 35 and 80 years, were investigated, particularly for the anatomy of the coronary sinus. The obliterated ostium of the coronary sinus to the right atrium associated with a persistent LSVC was present in only one (0.25%). We performed a diameter study of these structures since they were dilated due to the venous blood from the heart draining into the right atrium, by a communication between the LSVC and the left brachiocephalic vein. We also perform a literature review of these cases and discuss our finding in relation to its clinical importance. | |
