متن کاملContact force and force-time integral in atrial radiofrequency ablation predict transmurality of lesions.
AIMS During radiofrequency (RF) delivery, lesion volume is highly dependent on contact force (CF). It has recently been shown that changes of bipolar electrogram (EGM) predict transmurality. We hypothesized that there is a correlation between CF and EGM criteria of transmural lesion (TL) during RF. METHODS AND RESULTS We prospectively studied consecutive 512 RF applications from atrial fibril...
متن کاملRelation between impedance and endocardial contact during radiofrequency catheter ablation.
Lesion size during radiofrequency catheter ablation in patients with paroxysmal supraventricular tachycardia (PSVT) is thought to be related to multiple factors, including contact pressure at the catheter-endocardial interface. Therefore a predictor of contact pressure at a potential target site for ablation might be useful. In this study 25 patients underwent duplicate 2 W applications of radi...
متن کاملForce‐Sensing Catheters During Pediatric Radiofrequency Ablation: The FEDERATION Study
BACKGROUND Based on data from studies of atrial fibrillation ablations, optimal parameters for the TactiCath (TC; St. Jude Medical, Inc) force-sensing ablation catheter are a contact force of 20 g and a force-time integral of 400 g·s for the creation of transmural lesions. We aimed to evaluate TC in pediatric and congenital heart disease patients undergoing ablation. METHODS AND RESULTS Compr...
متن کاملEndocardial versus epicardial ventricular radiofrequency ablation: utility of in vivo contact force assessment.
BACKGROUND Contact force (CF) is an important determinant of lesion formation for atrial endocardial radiofrequency ablation. There are minimal published data on CF and ventricular lesion formation. We studied the impact of CF on lesion formation using an ovine model both endocardially and epicardially. METHODS AND RESULTS Twenty sheep received 160 epicardial and 160 endocardial ventricular r...
