In this study we used two different approaches in radiofrequency catheter ablation (RFCA) of the left free wall atrioventricular accessory pathway (AP): the retrograde transaortic (TAo) approach and the transseptal (TSA) one. Our aim was to evaluate the success rate and the duration of the two procedures. From May 1, 1991 to April 30, 1992, 33 pts (23 M, 10 F; mean age 38 +/- 16 years, range 14-66) with left free wall atrioventricular AP were selected among a 57 patient population, in which RFCA was performed for arrhythmias related to the AP. In 20/33 pts (61%) stable ventricular pre-excitation was present, while in 4/33 (12%) it was intermittent; in the remaining 9/33 pts (27%) only retrograde conduction through the AP was documented. In the majority of the pts (26/33) a diagnostic electrophysiologic study was performed immediately before the ablation procedure, during the same EP test. A 7 F steerable large tip catheter was used for energy delivery. In 8/33 pts, RFCA was performed by using only the TAo approach; other 7/33 pts underwent RFCA with a TSA technique after one completely unsuccessful retrograde TAo ablation and, in the remaining 18/33 pts, the TSA approach was used electively and continuously from January 1992. Overall, the TAo procedure has been carried out in 15 cases, while the TSA one in 25 cases. In the latter group, the ablation catheter was positioned against the left atrioventricular groove through a patent foramen ovale in 5/25 cases (20%), while a TSA puncture was needed in the remaining 20 cases. After successful ablation, the observation period was prolonged up to 60 min.
