Transseptal Catheterization of the Left Heart

Experiences with 200 transseptal catheterizations of the left heart are reported. The percutaneous insertion of the catheter into the femoral vein offers essential advantages. Investigations of all cavities of the heart may be performed through a single venous intubation. The examination have been carried out in patients with left-sided heart valve disease, especially aortic valve lesions, in complex congenital malformations and endocardial fibroelastosis. Own complications and incidents, as reported by different authors, are discussed. Severe complications can be avoided by use of the modified technic. The percutaneous transseptal catheterization is superior to other methods of left heart catheterization. The advantages and possibilities of the method are demonstrated.
