Abstract
1. Teflon tubing is ideally suited for transseptal catheterization because of its low coefficient of friction.
2. Catheterization of the left ventricle can be easily performed with a maneuverable spring guide.
3. A Teflon-tipped cannula and a tough, flexible, Teflon guide are used for percutaneous catheter insertions.
4. Safety measures used in transseptal puncture are described.
5. Simultaneous percutaneous insertion of a retrograde Teflon aortic catheter and the transseptal catheter permit transvalvular gradients to be obtained even when a diseased mitral or aortic valve cannot be crossed.
