Abstract
A method for placing various types of catheters into the pericardial space takes advantage of the fact that the right auricle is a thin-walled, low-pressure structure which can be readily penetrated without damaging the pericardium or the epicardium. A guide catheter is passed through a selected peripheral vein to establish a transvenous route to the right auricle of the heart. A needle catheter is then passed through the guide catheter and into the right auricle so that a distal end of the needle catheter is positioned against a wall of the right auricle. The wall of the right auricle is then pierced with the needle catheter. A guide wire is advanced through the needle catheter and into the pericardial space. Once in position, the guide wire can be used as a conduit over which a desired catheter may be introduced for performing a specific medical procedure.
