- New Ablation Catheters for Paroxysmal Atrial Fibrillation Treatment Could Improve Durability of Pulmonary Vein Isolation
June 14, 2011
Summary: The long-term effectiveness of atrial fibrillation catheter ablations may be improved by two new technologies, the TactiCath radiofrequency catheter and the CardioFocus laser balloon.
- An especially safe intracardiac catheter intervention without exposure to irradiance for children and adolescents
Nov 17, 2010
Summary: Cardiologists and Electrophysiologists at the University Hospital and Faculty of Medicine Tübingen in Germany were able to treat heart rhythm problems in an especially safe way without x-ray exposure, by using a new procedure, which controls the catheter’s contact force on the heart and vessel walls.
The intervention of a 16-year-old patient was conducted in October. Using this method, the x-ray free procedure, which is especially attractive for children due to its lack of exposure to irradiance, could be performed safely.
The system used to control the catheter intervention uses sensors to measure the catheters’ contact force and permits a three-dimensional tracing of the procedure. In the future, it can also be employed for catheter ablation of pregnant patients’ cardiac arrhythmias.
By using the newly developed TactiCathTM catheter (Endosense company), which measures the contact force continuously, the heart can carefully and safely be scanned without any exposure to irradiance.
