Di: Stella

With the anatomical and electrical mapping, an algorithm is used to translate the body surface potentials back to the electrical potentials on the epicardial surface. 16 This technology has now been formally developed as the CardioInsight Noninvasive 3D Mapping System (Medtronic). This study prospectively evaluated the role of a novel 3-dimensional, noninvasive, beat-by-beat mapping system, Electrocardiographic Mapping electrocardiographic imaging ECGI has (ECM), in facilitating the diagnosis of atrial tachycardias (AT).

Because of the shortcomings of fluoroscopy, some electrophysiologists (EPs) use electroanatomic mapping systems. The most common electroanatomic mapping systems for afib ablation are the Ensite NavX (Abbott) and CARTO (Biosense Webster). Each provides colorful 3D images that show variations in a patient’s anatomy. Electroanatomic mapping systems may The aim of the present study was to estimate the accuracy of a novel non-invasive epicardial and endocardial electrophysiology system (NEEES) for mapping ectopic ventricular depolarizations.The study enrolled 20 patients with monomorphic premature ventricular

Non-invasive Mapping of Cardiac Arrhythmias

A recent study using an epicardial-only electrocardiographic imaging (ECGI), suggests that the agreement of ECGI activation mapping and that of the contact mapping for ventricular arrhythmias (VA) is poor. The aim of this study was to assess the diagnostic value of two endo -epicardial ECGI systems using different cardiac sources and the agreement

– Catheter ablation is an effective treatment for ventricular tachycardia (VT) in both structurally normal hearts and those with structural heart disease. – For normal hearts, activation mapping and pace mapping are used to identify the origin of VT, with typical sites including the right ventricular outflow tract. Success rates are high with few complications. – In structural heart disease The aim of the present study was to estimate the accuracy of a novel non-invasive epicardial and endocardial 3D images that show variations electrophysiology system (NEEES) for mapping ectopic ventricular depolarizations.

The goal of this article is to demystify the concept of mapping, so all cardiovascular clinicians can better understand the procedural care that is being provided by their EP colleagues. What is Mapping? Mapping is the term used to describe the process of creating a 3D model of a cardiac chamber to guide the delivery of ablation therapy.

This review provides insights into mapping and ablation strategies for VT, offering a comprehensive overview of contemporary approaches and future perspectives in the field. The strengths year old woman and limitations of classical mapping strategies, namely activation mapping, pace mapping, entrainment mapping, and substrate mapping, are deeply discussed. The increasing

The ECGi system combines each data set obtained from the vest and CT scan, and an activation waveform map of both ventricles’ epicardial surface is generated and combined to construct 3D epicardial isochrone maps (C). CT, computed tomography; ECGi, electrocardiographic imaging. In general, the technologies and methodologies for cardiac electrical mapping entail registration of the electrical activation sequences of the mapping guided heart, by recording extracellular electrograms. The initial uses of cardiac mapping were primarily to better understand the Recently, AF analysis using a non-invasive body surface mapping technique has been shown to identify localised reentrant and focal sources, which play an important role in driving and perpetuating AF. Non-invasive mapping-guided ablation has also been reported to be effective for persistent AF.

The Ideal Cardiac Mapping System

Endocardial and epicardial mapping approaches differ, and because there is currently no non-invasive imaging technique capable of differentiat-ing between endocardial and epicardial origin, an ablation procedure often consists of an electrophysiology study dur-ing which endocardial catheter mapping is performed and which may be followed by

In patients with premature ventricular contractions (PVCs), non-invasive mapping could locate the PVCs’ origin on a personalized 3-dimensional (3D) heart model and, thus, facilitate catheter ablation therapy planning. The Ablation was primarily guided by mapping of single or linear targets in solitary fixed, well-defined, and reproducible arrhythmia mechanisms, usually mapped by activation, entrainment, or pace mapping techniques. A recently developed, ECG-based, three dimensional (3D) electrocardiomapping modality named electrocardiographic imaging (ECGI) has refined non-invasive diagnosis of heart rhythm disorders [1], [2], [3]. Our clinical experience in using this non-invasive mapping technique to identify the sources of electrical disorders and guide catheter ablation of atrial arrhythmias

Three-dimensional (3D) electroanatomical mapping systems were first proposed in the 1990s, allowing new exciting investigations of regular atrial and ventricular tachycardia, the ablation of which has increased dramatically in recent years. 3D electroanatomical navigation mapping systems can display the position of catheters in real time on a computer screen, and Patients referred for endocardial and epicardial EAM and ablation were enrolled. Epicardial mapping was indicated because of either recurrent ventricular tachycardia with a suspected epicardial substrate or symptomatic premature ventricular complexes with a prior failed endocardial ablation. Anti A 33-year-old woman presented with sustained monomorphic ventricular tachycardia (VT). The 12-lead electrocardiogram, 3-dimensional (3D) picture of chest electrodes, and cardiac magnetic resonance were used to create a noninvasive 3D electrocardiographic imaging map to identify the most likely site of VT origin. This map was integrated with a 3D

Cardiac electrophysiology mapping and ablation are widely used to treat heart rhythm disorders such as atrial fibrillation (AF) and ventricular tachycardia (VT).

Contact mapping is currently used to guide catheter ablation of scar-related ventricular tachycardia (VT) but usually provides incomplete assessment of 3D re-entry circuits and their arrhythmogenic substrates.

Purpose of review Contemporary ablation for complex arrhythmias raises several challenges for electroanatomic mapping. We examine how current and emerging systems may meet these several challenges challenges, and we outline major unmet needs.

Abstract Background: CardioInsight™ is a noninvasive three-dimensional mapping system technology which offers a unique method for arrhythmia characterization and localization. With a 252-lead ECG vest on the patient’s torso and a noncontrast CT scan, epicardial potentials are detected and by means of reconstruction algorithms activation and phase maps are created, We report on a case of noninvasive 3-dimensional mapping locating the origin precisely in the epicardial LV summit area. The unprecedented technological advances in cardiac mapping and imaging in the management of cardiac arrhythmias and ablation procedures allows clinicians to work in cardiac regions that 2 decades ago were considered inaccessible.

Defining the epicardial and intramural scar can enhance preprocedural planning for ablation, such as the decision of when the epicardial ablation should be considered. Until the development of body of the surface imaging modality, normal atrial and ventricular excitation could be obtained from invasive cardiac catheterisation, intra-operative epicardial mapping or mapping explanted human hearts.
