Comparison of new-generation renal artery denervation systems: assessing lesion size and thermodynamics using a thermochromic liquid crystal phantom model
Al Raisi, S; Barry, Michael A.; Qian, Pierre; Bhaskaran, Abhishek; Pouliopoulos, Jim; Kovoor, PrameshPublished 2017-11-20Aims: The aim of this study was to evaluate and compare lesion dimensions and thermodynamics of the new-generation multi-electrode Symplicity Spyral and the new-generation multi-electrode EnligHTN renal artery denervation ...Open AccessArticle -
Comparison of two different radiofrequency ablation systems for renal artery denervation: Evaluation of short-term and long-term follow up
Al Raisi, Sara; Pouliopoulos, Jim; Qian, Pierre; King, Patricia; Byth, Karen; Barry, Michael A.; Swinnen, John; Thiagalingam, Aravinda; Thomas, StuartPublished 2019-02-15Objectives: To assess the clinical efficacy of renal artery denervation (RAD) in our center and to compare the efficacy of two different radiofrequency (RF) systems. Background: Several systems are available for RF renal ...Open AccessArticle -
Quantitative Spectral Assessment of Intracardiac Electrogram Characteristics Associated with Post Infarct Fibrosis and Ventricular Tachycardia
Pouliopoulos, Jim; Morellato, JohnPublished 2018-09-01Background: Post-myocardial infarction (MI) remodeling contributes to increased electrophysiological and structural heterogeneity and arrhythmogenesis. Utilising the post-infarct ovine model our aim was to determine unipolar ...Open AccessDataset -
Spatial Characterization of Electrogram Morphology from Transmural Recordings in the Intact Normal Heart
Pouliopoulos, Jim; Chik, William; Byth, Karen; Wallace, Elizabeth; Kovoor, Pramesh; Thiagalingam, AravindaPublished 2014-09-15Purpose: Unipolar (UE) and bipolar electrograms (BE) are utilized to identify arrhythmogenic substrate. We quantified the effect of increasing distance from the source of propagation on local electrogram amplitude; and ...Open AccessDataset -
Transcatheter non-contact microwave ablation may enable circumferential renal artery denervation while sparing the vessel intima and media
Qian, Pierre; Barry, Michael A.; Al Raisi, Sara; Kovoor, Pramesh; Pouliopoulos, Jim; Nalliah, Chrishan; Bhaskaran, Abhishek; Chik, William; Kurup, Rahul; James, Virginia; McEwan, Alistair; Thiagalingam, Aravinda; Thomas, StuartPublished 2019-04-17Aims: Trials of transcatheter renal artery denervation (RDN) have failed to show consistent antihypertensive efficacy. Procedural factors and limitations of radiofrequency ablation can lead to incomplete denervation. The ...Open AccessPublisher version
