Why the study?
No study had quantified the movements of cardiac structures during high-frequency jet ventilation compared with normal mechanical ventilation.
Does high-frequency jet ventilation reduce coronary sinus movement in patients undergoing atrial fibrillation ablation compared to normal mechanical ventilation?
Does high-frequency jet ventilation reduce coronary sinus movement in patients undergoing atrial fibrillation ablation compared to normal mechanical ventilation?
High-frequency jet ventilation minimizes cardiac structure movement during atrial fibrillation ablation, which may improve catheter stability and mapping accuracy.
HFJV may reduce cardiac motion during AF ablation; leaves open whether this improves outcomes in prospective trials.
BACKGROUND: One of the reasons that high-frequency jet ventilation (HFJV) is used is due to the near immobility of thoracic structures. However, no study has quantified the movements of cardiac structures during HFJV compared with normal mechanical ventilation. METHODS: After ethical approval and written informed consent, we included 21 patients scheduled for atrial fibrillation ablation in this prospective crossover study. Each patient was ventilated with both normal mechanical ventilation and HFJV. During each ventilation mode, displacements of the cardiac structure were measured by the EnSite Precision mapping system using a catheter placed in the coronary sinus. CONCLUSION: This study quantifies the minimal movement of cardiac structures during HFJV compared to standard mechanical ventilation.
