2017 AF Symposium
Live Case: Ablation using CardioFocus Laser Balloon

Video streaming from Na Homolce Hospital in Prague, The Czech Republic. Drs. Peter Neuzil, Jan Petru and Jan Skoda, in their second live case, did an ablation using the CardioFocus HeartLight Endoscopic Visually Guided Laser Balloon (FDA approved April 4, 2016).
Direct Visualization
The doctors showed how they could directly see the Pulmonary Vein opening they were ablating (unlike RF and CryoBalloon systems).
The center of the catheter has an endoscopic (looking inside) camera. (To me, this is a major advantage and ground-breaking improvement for patients.) (Watch :13 video clip)
Laser Energy For Ablation


In the center of the catheter is an optical fiber which produces an arc of laser (near infrared) energy. When they applied this laser energy, it looked like a green flashing light that circled the PV.
The doctors said that watching this circulating green arc allowed them to visually see if they were making complete circular lesions of the PV.
They later used a regular Lasso catheter to check for ablation integrity.
Variable Diameter Compliant Balloon
The doctors also showed how the CardioFocus HeartLight system uses a variable diameter compliant balloon which can be sized to fit into a wide range of PV openings.
One preliminary research article suggested that the Laser Balloon system clinical outcomes were an improvement over CryoBalloon ablation.

Editor’s Comments:
The CardioFocus HeartLight Laser Balloon catheter seems like a major advance in the treatment of A-Fib, To be able to look directly at the PV opening instead of using fluoroscopy, etc. should make an EP’s ablation task much easier and potentially more effective. And having a variable diameter compliant balloon is an added plus.
But when I talked with the CardioFocus rep at the AF Symposium exhibit hall, he said they were in the process of rolling out the Laser Balloon system to various centers. It may be a short while till the system is up and operational nationwide in the U.S. (It’s already in use in Europe.) We will try to list which centers use the Laser Balloon system.
If real world experience proves its effectiveness, the CardioFocus HeartLight Laser Balloon system may eventually make CryoBalloon ablation a secondary player.
