Echocardiographic routine analysis of the coronary sinus by an apical view: normal and abnormal features

Abstract

The echocardiographic aspects of the coronary sinus have not received much attention in the literature. In the few published articles about anomalous venous connection to the coronary sinus, the parasternal long axis view has been suggested as ideal for its visualization. More recently, it has been suggested that the coronary sinus in normal hearts is best visualized from the apical transducer position. The purpose of this study was to assess the appearance of the coronary sinus from an apical view in a group of 400 consecutive patients with ages varying from 5 days to 80 years. In ten patients with persistent left superior vena cava, the coronary sinus was markedly dilated throughout its extension. All cases were confirmed either by angiography or surgery. In another three patients with Ebstein's anomaly studied postoperatively, it was observed that the coronary sinus was abnormally draining into the right ventricle below the prosthesis plane. These findings were confirmed by the surgical reports. The routine evaluation of the coronary sinus was better performed by an apical view, which provided detailed information not only of normal, but also abnormal anatomy of this segment of the heart. We speculate that it could be especi...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
