Intracardiac shunts resulting from transseptal catheterization for ablation of accessory pathways in otherwise normal hearts.
In a series of 14 patients undergoing transseptal catheterization for ablation of left-sided accessory pathways, hydrogen appearance time was used to detect left-to-right shunting after removal of the catheter. Six of the 12 patients who had no evidence of shunt before catheterization had evidence of shunting after the procedure.
