Punción transeptal mediante referencias electrofisiológicas para procedimientos de ablación

We report our experience with transseptal catheterization in an electrophysiology laboratory using only electrophysiological landmarks. The procedure was carried out on 68 occasions and was successful in all patients except one, in whom catheterization could not be performed for anatomical reasons and because the patient had previously received anticoagulation therapy. One other patient developed transient ST elevation, which was probably due to an air embolism.
