Journal ArticleDOI
Substrate modification combined with pulmonary vein isolation improves outcome of catheter ablation in patients with persistent atrial fibrillation : a prospective randomized comparison
Stephan Willems,Hanno U. Klemm,Thomas Rostock,Benedikt Brandstrup,Rodolfo Ventura,Daniel Steven,Tim Risius,Boris Lutomsky,Thomas Meinertz +8 more
TL;DR: PVI alone is insufficient in the treatment of persistent AF, however, additional left linear lesions increase the success rate significantly.
Journal ArticleDOI
Heparins Increase Endothelial Nitric Oxide Bioavailability by Liberating Vessel-Immobilized Myeloperoxidase
Stephan Baldus,Volker Rudolph,Mika Roiss,Wulf D. Ito,Tanja K. Rudolph,Jason P. Eiserich,Karsten Sydow,Denise Lau,Katalin Szöcs,Anna Klinke,Lukáš Kubala,Lars Berglund,Sonja Schrepfer,Tobias Deuse,Munif Haddad,Tim Risius,Hanno U. Klemm,Hermann Reichenspurner,Thomas Meinertz,Thomas Heitzer +19 more
TL;DR: Mobilization of vessel-associated MPO may represent an important mechanism by which heparins exert antiinflammatory effects and increase vascular NO bioavailability in humans.
Journal ArticleDOI
Catheter Ablation of Atrial Flutter Guided by Electroanatomic Mapping (CARTO): A Randomized Comparison to the Conventional Approach
Stephan Willems,Christian Weiss,Rodolfo Ventura,Rudolf Rüppel,Tim Risius,Matthias C. Hoffmann,Thomas Meinertz +6 more
TL;DR: The aim of the present study was to assess the efficacy of the CARTO navigation system, especially with respect to the fluoroscopy time required for successful atrial flutter ablation.
Journal ArticleDOI
Correlation of Symptoms to ECG Diagnosis Following Atrial Fibrillation Ablation
Hanno U. Klemm,Rodolfo Ventura,Thomas Rostock,Benedikt Brandstrup,Tim Risius,Thomas Meinertz,Stephan Willems +6 more
TL;DR: This study evaluated the correlation between symptoms and the underlying rhythm after AF ablation to determine the definition of success following atrial fibrillation (AF) ablation.
Journal ArticleDOI
Efficacy and safety of radiofrequency catheter ablation of atrioventricular nodal reentrant tachycardia in the elderly
Thomas Rostock,Tim Risius,Rodolfo Ventura,Hanno U. Klemm,Christian Weiss,Anna Keitel,Thomas Meinertz,Stephan Willems +7 more
TL;DR: The purpose of the study was to investigate the success and complication rate particularly regarding the induction of an atrioventricular (AV) block by radiofrequency (RF) ablation in elderly patients with and without a preexisting AV block.
