What is cavo-tricuspid isthmus?

The cavo-tricuspid isthmus is a narrow tract of tissue located in the right atrium of the heart, between the inferior vena cava and the tricuspid valve. It is an important pathway for electrical impulses during the process of cardiac conduction, which helps to regulate the rhythm of the heart. The cavo-tricuspid isthmus is a target for ablation therapy, a procedure used to treat certain types of heart arrhythmias. Successful ablation of this area can help to restore normal heart rhythm and reduce the risk of complications.
