placing diagnostic catheter in the coronary sinus

Description :The coronary sinus is a vein that drains the heart into the right atrium. It travels through a portion of the heart, between the upper and lower chambers. It provides an excellent site to read the electrical activity of the left upper and left lower chambers of the heart, without having to puncture the septal wall. The ability to read the electrical activity of both chambers simultaneously is important for identifying the correct target sites for ablation. While this process is lengthy, the neck site offers greater stability to the catheter than the groin. <br/> You will see a CT image of the heart with just the left atrium and the pulmonary veins extending from the body that was created from the raw data obtained by CT of the heart done before the ablation procedure.
