Abstract Funding Acknowledgements Type of funding sources: Private company. Main source(s): Abbott Laboratories Background Ablation ventricular tachycardia (VT) in patients with structural heart disease is challenging. Localization the critical isthmus conduction may be difficult because commonly located within low voltage (LV) areas where far-field (FF) and near-field (NF) electrograms (EGMs) present merged. The peak frequency (PF) associated bipolar EGMs a novel parameter which serve to...
Abstract Funding Acknowledgements Type of funding sources: None. Background Left atrial flutter (LAFL) may have epicardial components not accessible to endocardial ablation by radiofrequency (RF) application. Subxiphoid access the pericardial space has been reported in isolated cases. Purpose prospectively evaluate efficacy and safety subxiphoid map ablate LAFL refractory RF Methods Patients with confirmed activation entrainment mapping application were consecutively enrolled. An component...
Abstract Funding Acknowledgements Type of funding sources: None. Background Subxiphoid percutaneous access to the pericardial space for mapping and ablation atrial ventricular arrhythmia carries potential risk cardiac perforation coronary artery laceration. Widening with saline solution or carbon dioxide (CO2) insufflation by intentional vein exit prior subxiphoid puncture reduces organ lesion. However, cannulation a branch is often difficult adds complexity procedure. Purpose To determine...
Cardiac arrhythmia affects a large portion of the population, particularly elderly. As population ages, number patients suffering from this condition is expected to rise, underlining importance more efficient treatment methods. Radio-frequency (RF) catheter ablation choice for many cardiac arrhythmias. To recover normal heartbeat, abnormal pacemakers inside heart are first identified and then isolated or destroyed by applying RF energy through use an catheter. While catheter’s design precise...
Abstract Background Complex atrial fibrillation (AF) and left flutter (LAFL) ablation procedures often involve creating lines on the anterior wall of atrium, such as septal lateral mitral isthmus lines. Purpose This study aims to evaluate role a simplified criteria demonstrate achievement conduction block across atrium ("anterior isthmus") after linear (LA). Methods Patients scheduled for persistent AF or LAFT were prospectively recruited. The procedure employed homogeneous LA strategy that...
Abstract Background In recent years, success rate of left atrial flutter (LAFL) ablation has witnessed improvement, attributed to enhanced comprehension the arrhythmia mechanism and technological advancements. However, recurrence specific types arrhythmias, along with their potential predictors, remain inadequately understood. Purpose The aim this study is assess factors influencing efficacy, safety, long-term radiofrequency (RF) for LAFL. Methods Patients sustained LAFL undergoing RF were...
Abstract Funding Acknowledgements Type of funding sources: None. Background Adenosine (ADN) infusion may terminate focal atrial tachycardia (AT). However, the effect ADN on reentrant (RAT) is unclear and based case reports small series. These latter included mostly patients with cavotricuspid isthmus-dependent flutter provided conflicting results, RAT termination found when it involved septal or tricuspid/mitral valve regions. Purpose The aim this study was to test response (termination,...
Abstract Funding Acknowledgements Type of funding sources: Private company. Main source(s): Abbott Laboratories Background Localization the critical isthmus conduction LAMRT circuits within scar tissue is challenging (Panel A). Low voltage (LV) has been used as a marker for arrhythmic substrate. However, amplitudes due to near field (NF) vs. far-field (FF) electrogram (EGM) components are not clearly differentiated. The peak frequency (PF) associated with bipolar EGM’s novel parameter which...
