Mapping and ablation of ventricular fibrillation substrate
Springer Science and Business Media LLC - - Trang 1-14 - 2023
Fatima M. Ezzeddine, Robert Charles Ward, Samuel J. Asirvatham, Christopher V. DeSimone
Ventricular fibrillation (VF) is a life-threatening arrhythmia and a common cause of sudden cardiac death (SCD). A basic understanding of its mechanistic underpinning is crucial for enhancing our knowledge to develop innovative mapping and ablation techniques for this lethal rhythm. Significant advances in our understanding of VF have been made especially in the basic science and pre-clinical expe...... hiện toàn bộ
Relationship between left atrium catheter contact force and pacing threshold
Springer Science and Business Media LLC - Tập 49 - Trang 147-155 - 2017
Teresa Barrio-López, Mercedes Ortiz, Eduardo Castellanos, Carla Lázaro, Jefferson Salas, Sergio Madero, Jesús Almendral
The purpose of this study is to analyze the relationship between contact force (CF) and pacing threshold in left atrium (LA). Six to ten LA sites were studied in 28 consecutive patients with atrial fibrillation undergoing pulmonary vein isolation. Median CF, bipolar and unipolar electrogram voltage, impedance, and bipolar and unipolar thresholds for consistent constant capture and for consistent i...... hiện toàn bộ
Diagnosis of cardiac amyloidosis in patients undergoing catheter ablation for atrial arrhythmias

Nienaber, Kambis Mashayekhi, Muharrem Akin, Thomas Bertsch, Christel Weiß, Martin Borggrefe, Ibrahim Akin
The study sought to assess retrospectively the prognostic impact of left ventricular ejection fraction (LVEF) in patients with electrical storm (ES). Data regarding the prognostic impact of impaired LVEF in ES patients is rare. Consecutive patients presenting with ES from 2002 to 2016 were included retrospectively. Patients with LVEF ≤ 35% were compared to patients with LVEF > 35%. The primary pro...... hiện toàn bộ
Real-time integration of intracardiac echocardiography and 3D electroanatomical mapping to guide catheter ablation of isthmus-dependent atrial flutter in a patient with complete situs inversus and interruption of the inferior vena cava with azygos continuation
Springer Science and Business Media LLC - Tập 30 - Trang 273-277 - 2009
Giovanni B. Forleo, Augusto Pappalardo, Andrea Avella, Lidia Visigalli, Antonio Dello Russo, Claudio Tondo
Atrial tachycardias are relatively common in patients with congenital heart disease. However, complex anomalies involving the heart and the great vessels might compromise the results of the ablation procedure. This report describes a clinical application of the new Cartosound™ module as an adjunctive technology to understand the mechanism of the arrhythmia and to guide successfully the ablation in...... hiện toàn bộ
Remote-controlled magnetic ablation of a right anterolateral accessory pathway—The superior caval vein approach
Springer Science and Business Media LLC - - 2006
Julian Kyoung-Ryul Chun, Boris Schmidt, Karl-Heinz Kuck, Sabine Ernst
An 18-year old male patient with recurrent supraventricular tachycardias was admitted for catheter ablation. Baseline ECG was consistent with right anterolateral accessory pathway (AP) conduction. The novel magnetic navigation system (MNS, Niobe Stereotaxis) in combination with a catheter advancer unit (Cardiodrive, Stereotaxis) allows a complete remote-controlled electrophysiologic study and abla...... hiện toàn bộ
Pulmonary vein stenosis after pulmonary vein isolation using duty-cycled unipolar/bipolar radiofrequency ablation guided by intracardiac echocardiography
Springer Science and Business Media LLC - Tập 44 - Trang 47-54 - 2015
Stefan Asbach, Fabienne Schluermann, Luca Trolese, Mathias Langer, Christoph Bode, Tobias Krauss
Concerning rates of pulmonary vein (PV) stenosis were reported following PV isolation (PVI) with a circular pulmonary vein ablation catheter (PVAC). As this may depend on intraprocedural imaging, we evaluated the incidence of PV stenosis in patients undergoing PVAC-PVI with continuous surveillance by intracardiac echocardiography (ICE). Multi-slice computed tomography was performed before and 3 mo...... hiện toàn bộ
A contemporary view of atrioventricular nodal physiology
Springer Science and Business Media LLC - Tập 52 - Trang 271-279 - 2018
Steven M. Markowitz, Bruce B. Lerman
In delaying transmission of the cardiac impulse from the atria to the ventricles, the atrioventricular (AV) node serves a critical function in augmenting ventricular filling during diastole and limiting the ventricular response during atrial tachyarrhythmias. The complex structure of the nodal region, however, also provides the substrate for reentrant rhythms. Recent discoveries have elucidated th...... hiện toàn bộ
Coronary sinus anatomy by computerized tomography, overlaid on live fluoroscopy can be successfully used to guide left ventricular lead implantation: a feasibility study
Springer Science and Business Media LLC - Tập 36 - Trang 217-222 - 2012
Zoubin Alikhani, Jonathan Li, Juan A. Merchan, Niels Nijhof, Jeffrey Mendel, Michael V. Orlov
This study aims to optimize coronary sinus (CS) computerized tomography (CT) imaging and evaluate its utility for preprocedural planning and intraoperative guidance by overlay of 3D reconstructed CS images on live fluoroscopy. Optimal CS lead placement for cardiac resynchronization therapy (CRT) remains challenging. Preprocedural knowledge of CS anatomy can significantly affect procedural outcome....... hiện toàn bộ
