Outcomes following cryoballoon ablation for atrial fibrillation guided by pressure waveform monitoring without the routine use of pulmonary venography

Purpose Pressure waveform analysis has the potential for facilitated assessment of pulmonary vein occlusion during cryoballoon ablation for atrial fibrillation. Data on clinical outcomes using this method are lacking. We sought to validate through clinical outcomes the use of pressure waveform analysis as the primary method of determining pulmonary vein occlusion during cryoballoon ablation.
