High frequency jet ventilation for motion management during ablation procedures, a narrative review

Area of Science:

• Medical Technology
• Surgical Innovation
• Cardiovascular Interventions

Background:

• High frequency jet ventilation (HFJV) is a ventilation method gaining interest for its ability to minimize organ movement.
• This technique enhances surgical precision in minimally invasive procedures like ablation for atrial fibrillation and tumors.

Purpose of the Study:

• To review current evidence on the clinical application of HFJV in ablative procedures.
• To summarize the efficacy and outcomes associated with HFJV during ablation.

Main Methods:

• A systematic literature search was conducted on PubMed using keywords 'high frequency ventilation' and 'ablation' from January 1990 to December 2016.
• Inclusion criteria were applied to 34 initially identified papers, resulting in 16 studies for review (4 reviews, 12 human studies).
• Studies included a total of 889 patients (498 HFJV, 391 controls); no randomized controlled trials were found.

Main Results:

• The review included 16 studies involving 889 patients, comparing HFJV to controls.
• While scientific quality was generally low, findings suggest HFJV reduces tissue movement, potentially improving surgical precision.
• Observed benefits included shorter procedure times and reduced recurrence of atrial fibrillation.

Conclusions:

• There is a significant lack of well-designed studies evaluating HFJV in ablation procedures.
• Existing evidence, though limited, suggests HFJV can enhance surgical precision and improve outcomes.
• Randomized controlled trials are necessary to validate the benefits of HFJV over standard ventilation techniques.
