Q. Give Choice of Catheters for Ventriculography?

1) Pigtail Catheter: This catheter developed by Judkins has end hole and side holes. The end hole permits insertion of the catheter over a J-tipped guide wire so that it can be safely advanced into the ventricle. The loop keeps the end hole away from direct contact with the endocardium. The multiple side holes permit simultaneous exit routes for the contrast and help to stabilize the catheter and prevent recoil.

2) Sones Catheter

3) NIH and Eppendorf Catheters

4) Lehman Catheter
