Acute and long-term outcome after catheter ablation of supraventricular tachycardia in patients after the Mustard or Senning operation for D-transposition of the great arteries

Abstract

Catheter ablation of IART or AVNRT in patients post-Mustard/Senning operation for d-TGA has a high acute success rate. The recurrence rate for IART is about 30%; however, after a second ablation, long-term results are excellent. Remote magnetic navigation seems to improve single-procedure acute and long-term success and significantly reduces FT and PD.
