Summary
The VersaCross radiofrequency system significantly reduces procedural time for percutaneous left atrial appendage closure (LAAC), offering a safe and efficient alternative to mechanical needles for WATCHMAN implantation.
Area of Science:
- Cardiology
- Medical Devices
- Interventional Cardiology
Background:
- Percutaneous left atrial appendage closure (LAAC) is an emerging therapy for atrial fibrillation patients unsuitable for anticoagulation.
- The choice of transseptal puncture device impacts procedural efficiency and safety.
Purpose of the Study:
- To compare the VersaCross radiofrequency system with the mechanical Brockenbrough needle for WATCHMAN implantation.
- To evaluate differences in procedural time, workflow, and adverse events between the two systems.
Main Methods:
- Prospective enrollment of 20 patients undergoing LAAC at Vancouver General Hospital.
- Comparison of 10 patients using the VersaCross system versus 10 patients using the Brockenbrough needle.
- Detailed recording of procedural workflow, times, and complications.
Main Results:
- 100% success rate for transseptal puncture with both systems.
- The radiofrequency system reduced total procedural time by 27% (21.5 vs 29.5 minutes; P=.008).
- Reduced fluoroscopy and contrast use were observed with the radiofrequency system without increased complications.
Conclusions:
- The VersaCross radiofrequency system streamlines LAAC workflow, proving safe and efficient.
- It offers a viable alternative to mechanical puncture methods for WATCHMAN implantation.
- Larger randomized trials are recommended to validate these findings.
