Radiofrequency Ablation Clinical Trial
Official title:
Randomized Comparison Between Magnetically Navigated vs Manually Guided Radiofrequency in AV-node-reentry-tachycardia
The MAGMA-AVNRT study compares two different methods of handling the ablation catheters for av-node-reentry-tachycardia with regard to x-ray dose, safety and success: manually guided vs magnetically navigated RF-catheter.
AV-node reentry tachycardia can be treated by radiofrequency ablation or modulation of the
slow pathway of the av node. The success rate is 90 to 95%.
There are different options to navigate the ablation catheter: manually guided vs
magnetically guided.
For magnetic guidance two magnets are positioned beneath the patient. A mangetic field is
induced and a catheter with a ferromagnetic tip can be navigated from outside with a
joystick by modifying the vectors of the magnetic field.
We hypothesized that a magnetic guidance of the RF-ablation catheter results in lower x-ray
time and dose for the patient and the physician with comparable safety und success rates.
