The first type, with an end hole, such as the Lehman catheter, has certain disadvantages for selective angiocardiography because of its tendency to recoil during injections. In addition, it is stiff and this increases the difficulties and dangers of intracardiac manipulation. Undesirable damping and difficulty with sampling may also occur with this catheter.The second type is the side-hole catheter which overcomes these difficulties and permits sampling and pressure recording as well as rapid
