..The purpose of this study was to characterize the relationship between changes in body mass index (BMI) and incident atrial fibrillation (AF) in a large cohort of women...

..Potential risks include risk of injury to an epicardial coronary artery, the phrenic nerve, subdiaphragmatic vessels, and right ventricle. We describe the indications for and approach to catheter ablation of VT for the pericardial space...

..That increases in stimulus strength (SS) can affect VA has been demonstrated previously in cardiomyopathy patients undergoing ablation...

..22, 95% confidence interval 1.54 to 11.6) remained significant. In conclusion, despite resynchronization, patients with high RV pressures have significantly decreased survival after adjusting for significant contributing influences...

..After encouraging results with transcoronary ethanol ablation (TCEA), we began offering TCEA routinely when endocardial and epicardial RFCA failed or a deep intramural substrate was likely...

..Conclusions- In patients with recurrent VT due to nonischemic heart disease, catheter ablation is often useful, although the outcome varies according to the nature of the underlying heart disease...

..There is a paucity of data on the contribution of this region to VTs in patients with structural heart disease...

..Updated understanding of the risks of catheter ablation is important because techniques have evolved for procedures treating non-life-threatening as well as potentially lethal arrhythmias...

..Wider use of this simple nongeometric parameter may help to identify patients for whom options for further intervention should be carefully evaluated...

..There is a paucity of data on the success rates of achieving percutaneous epicardial access in different groups of patients...

..Advances in understanding of genetic arrhythmia syndromes and in technology for mapping and ablation of ventricular arrhythmias, and enhanced algorithms in implantable devices for rhythm management, have contributed to improved outcomes...

..In patients with ischemic heart disease, ventricular tachycardia (VT) is associated with increased mortality and morbidity. Catheter ablation is useful for reducing VT therapies but remains challenging, and recurrences are common...

..The study aims to investigate the incidence, management, and hospital outcomes of cardiac perforation complicating catheter ablation for ventricular arrhythmias...

..The influence of systolic and diastolic blood pressure (BP) on incident atrial fibrillation (AF) is not well studied among initially healthy, middle-aged women...

..VT Ablation in Apical Hypertrophic Cardiomyopathy. ..

..We tested proposed algorithms for idiopathic and nonischemic tachycardias for their ability to identify epicardial LV-VT origins...

..Unipolar recordings are not subject to directional influence. We hypothesized that high-pass filtered unipolar EGs would provide similar information to bipolar EGs, without potential errors related to wavefront direction...

..Risk stratification for patients with suspected Brugada syndrome (BS) remains difficult. Implantation of cardioverter-defibrillators (ICDs) in high-risk patients provides continuous long-term arrhythmia protection...

..Radiofrequency catheter ablation is useful for reducing VT therapy in patients with an implantable defibrillator. The utility of radiofrequency catheter ablation in the elderly is not well defined...

..We investigated the substrate, procedure, and outcome evolution of all patients referred for VT ablation during the past 8 years...

..The end of the TZ is marked by the first beat with a stable QRS morphology but is a subjective assessment. Disagreement concerning this beat may change tachycardia diagnosis...

..Currently, only anecdotal information exists on the presentation and outcome of coronary arterial injury after ablation procedures...

..However, these studies were not powered to investigate the association of alcohol consumption and atrial fibrillation among women...

..Other chronic diseases are known to not only affect the patient but to also impact the QoL of persons living with them. Scant data exist on the QoL effect of AF in spouses/significant others (SOs)...

..Few if any studies have assessed the relationship between birth weight and incident atrial fibrillation (AF)...

..To assess the joint influence of inflammatory biomarkers on the risk of incident atrial fibrillation (AF) in women...

..The causes of sustained monomorphic ventricular tachycardia (VT) after cardiac valve surgeries have not been studied extensively, although bundle-branch reentry has been reported...

..However, clinical trials report higher rates of appropriate ICD therapies in implanted patients than untreated patient mortality rates would predict...

..The electrocardiographic characteristics of the arrhythmia and clinical characteristics of the patient are important considerations in the immediate and long-term management considerations...

..Ablation of atrial tachycardias (AT) arising from the crista terminalis region (CT) can be complicated by phrenic nerve (PN) injury...

..Management of atrial arrhythmias (AA) in orthotopic heart transplant (OHT) patients is challenging...

..Surgical cryoablation targeting the area around the LV lead eliminated VT. Thus pacing maneuvers from permanent epicardial leads can occasionally help identify an epicardial VT origin...

..Fascicular tachycardia (FT) is an uncommon cause of monomorphic sustained ventricular tachycardia (VT). We describe 6 cases of FT with multiform QRS morphologies...

..The identified loci implicate candidate genes that encode transcription factors related to cardiopulmonary development, cardiac-expressed ion channels and cell signaling molecules...

..Insights into the relation between anatomic isthmuses identified by delineating unexcitable tissue using substrate mapping techniques and critical reentry circuit isthmuses might facilitate ablation...
