OBJECTIVE To assess if patients treated with omega-3(n-3) polyunsaturated fatty acids (PUFAS) had lower procedural failure rates compared to an untreated population. METHODS AND RESULTS From January 2004 to 2007, 1500 PVAI patients underwent catheter ablation. Two hundred and eighty five (19%) patients were treated with PUFAs. These patients were matched(More)
BACKGROUND During radiofrequency ablation, effective contact is crucial in determining lesions efficacy. OBJECTIVE The purpose of this study was to compare operators' ability to assess contact pressure using visual and tactile feedbacks together or alone in an experimental model. METHODS In a in vitro experimental setup replicating manual catheter(More)
