The MI block could be achieved in the majority of patients by using a steerable sheath. An incomplete MI block increased the risk of AT following persistent AF ablation.

High BMI was associated with better clinical outcomes in Japanese CHF patients.

Low eGFR and LA dilatation independently influence the outcome of catheter ablation for paroxysmal AF.

The use of a steerable sheath reduced the time and amount of energy needed to achieve a bidirectional conduction block in the CTI. For patients in whom the establishment of a conduction block is difficult, a steerable sheath should be considered as a therapeutic option for typical AFL ablation.
