Catheter Ablation for Tachycardias
T ACHY ARRHYTHMIAS constitute a major cause of mortality and morbidity. The most serious manifestation of cardiac arrhythmia is sudden cardiac death where the underlying rhythm is ventricular tachycardia-ventricular fibrillation (VT VF) in the vast majority of patients. I Other symptoms produced by cardiac arrhythmias are syncope, near syncope, lightheadedness, and palpitations. Although suprav...
متن کاملImplications for Catheter Ablation
Background. The primary mechanism of tissue injury by radiofrequency catheter ablation is presumed to be thermally mediated. However, the myocardial cellular electrophysiological effects of hyperthermia are not well characterized. We used an in vitro model of isolated guinea pig right ventricular papillary muscle to investigate the acute cellular electrophysiological effects of hyperthermia. Me...
متن کاملBody mass index, obstructive sleep apnea, and outcomes of catheter ablation of atrial fibrillation.
BACKGROUND Obesity and obstructive sleep apnea (OSA) are associated with atrial fibrillation (AF). The effects of a large body mass index (BMI) and OSA on the results of radiofrequency catheter ablation (RFA) of AF are unclear. OBJECTIVE To evaluate the effect of BMI and OSA on the efficacy of RFA for AF. METHODS RFA was performed in 324 consecutive patients (mean age = 57 +/- 11 years) wit...
متن کاملEffect of isthmus anatomy and ablation catheter on radiofrequency catheter ablation of the cavotricuspid isthmus.
BACKGROUND Cavotricuspid isthmus (CTI) characteristics are rarely documented when comparing catheters in radiofrequency ablation (RFA) of atrial flutter (AFL). Our objectives were (1) to evaluate the impact of CTI morphology and length on ablation procedures and (2) to compare the efficacy of an 8-mm-tip catheter with an irrigated cooled-tip RFA in the subgroup presumed to be more difficult to ...
متن کاملBody Mass Index, Quality of Life, and Catheter Ablation in Patients with Atrial Fibrillation.
Atrial fibrillation and obesity are interlinked epidemics and both impair quality of life. As the prevalence of both conditions in the US continues to rise, so will the number of obese patients with atrial fibrillation referred for catheter ablation. Catheter ablation has already been shown to significantly improve quality of life in patients with atrial fibrillation. Until recently, there has ...
