Ablation is a treatment for abnormalities in heart rhythm or impulse conduction. It involves destructing the defective tissue in the heart through a surgical open heart procedure or the new transcatheter technique, which Saint Francis physicians helped to develop. In the transcatheter procedure, special low-level radio-frequency energy is used to produce ablation. A specially designed catheter destroys the tissue in less than half the time and with greater accuracy than previous techniques. Also, with the newer techniques, patients do not need general anesthesia.
Three-dimensional EKG mapping, also developed by a Saint Francis heart specialist, has improved the precision of the ablation procedure which is rapidly becoming the technique of choice for many supraventricular tachycardias.
