Focal Impulse and Rotor Modulation (FIRM) for Paroxysmal and Persistent Atrial Fibrillation

01/03/2013

David E. Krummen , MD;

Thomas McGarry , MD;

Marian Holland , MD;

Sanjiv M. Narayan , MD, PhD, MSc;

This review focuses on the evidence that stable rotors and focal sources drive paroxysmal AF, as well as persistent AF, where FIRM can substantially reduce the extent of atrial ablation and increase success rates.

This review focuses on the...

Ablating Rotors and Focal Beat Sources of Atrial Fibrillation to Improve Outcome: The CONFIRM Trial

02/28/2012

Kalayanam Shivkumar , MD, PhD;

David E. Krummen , MD;

Sanjiv M. Narayan , MD, PhD, MSc;

John M. Miller , MD;

The success of the approach of Focal Impulse and Rotor Modulation (FIRM) ablation for AF led to the CONFIRM trial, and to the initiation of clinical programs for FIRM ablation at several institutions beyond the initial study group.

The success of the approach of...
