Three dimensional echocardiography in valvular heart disease

Publikováno v: SA Heart Journal, Vol 7, Iss 2, Pp 106-113 (2017)

Although cardiac structures exist in three dimensions, two dimensional (2-D) echocardiography only provides information in a single tomographic plane, the orientation of which is determined by the ultrasound window. Accordingly the use of geometric a

Characterization of persistent atrial fibrillation with non‐contact charge density mapping and relationship to voltage

Autor: Thomas A. Nelson, Richard H. Clayton, Justin M.S. Lee, Nicholas F. Kelland

Publikováno v: Journal of Arrhythmia, Vol 38, Iss 1, Pp 77-85 (2022)

Background Despite studies using localized high density contact mapping and lower resolution panoramic approaches, the mechanisms that sustain human persistent atrial fibrillation (AF) remain unresolved. Voltage mapping is commonly employed as a surr

31 Utilisation of an existing exercise-based cardiac rehabilitation programme for patients with atrial fibrillation in the national health service: putting current services to good use

Autor: Andrew Horwood, Justin M.S. Lee, Elizabeth Johnson, Mark T Mills, Graeme Kirkwood, Nicola Lax, Anna Gregory, Sarah Charlesworth, Andreas Kyriacou, Nicholas F. Kelland, Jonathan Sahu, Hamza Zafar

Publikováno v: Cardiac Rhythm Management.

Introduction Exercise-based cardiac rehabilitation is an established intervention in the management of several cardiovascular conditions, including ischaemic heart disease and heart failure. There is increasing recognition for the role of exercise-ba

P Wave Morphology in Guiding the Ablation Strategy of Focal Atrial Tachycardias and Atrial Flutter

Autor: Justin M.S. Lee, Simon P. Fynn

Publikováno v: Current Cardiology Reviews

Focal atrial tachycardias arise preferentially from specific locations within the atria. Careful analysis of the P wave can provide useful information about the chamber and likely site of origin within that chamber. Macro-reentrant atrial flutter als

Catheter-Tissue Contact Force Determines Atrial Electrogram Characteristics Before and Lesion Efficacy After Antral Pulmonary Vein Isolation in Humans

Autor: Joseph B. Morton, Peter M. Kistler, Martin Chan, Matias Yudi, Michael C.G. Wong, Jonathan M. Kalman, Steven J. Spence, Justin M.S. Lee, Saurabh Kumar, Karen Halloran

Publikováno v: Journal of Cardiovascular Electrophysiology. 25:122-129

Catheter-Tissue Contact Force Determines Atrial Electrogram Characteristics Introduction Electrogram (EGM) characteristics are used to infer catheter-tissue contact. We examined if (a) atrial EGM characteristics predicted CF and (b) compared the valu

Effects of high dose intravenous fish oil on human atrial electrophysiology: Implications for possible anti- and pro-arrhythmic mechanisms in atrial fibrillation

Autor: Timothy Robinson, F. Sutherland, Patrick M. Heck, Nicholas F. Kelland, Paul B. Sparks, Manohar L. Garg, Michael C.G. Wong, Saurabh Kumar, Justin M.S. Lee

Publikováno v: International Journal of Cardiology. 168:2754-2760

Intravenous omega-3 polyunsaturated fatty acids (ω-3 PUFAs) may prevent atrial fibrillation (AF) inducibility and perpetuation in animal models. We examined the effect of high dose IV ω-3 PUFAs on human atrial electrophysiology.We randomised 88 pat

Predictive value of impedance changes for real-time contact force measurements during catheter ablation of atrial arrhythmias in humans

Publikováno v: Heart Rhythm. 10:962-969

Background Catheter-tissue contact force (CF) determines radiofrequency (RF) ablation lesion size. Impedance changes during RF delivery are used as surrogate markers for CF. The relationship between impedance and real-time CF in humans remains unknow

Prospective Characterization of Catheter–Tissue Contact Force at Different Anatomic Sites During Antral Pulmonary Vein Isolation

Autor: Joseph B. Morton, Peter M. Kistler, Alexandra Gorelik, Steven J. Spence, Justin M.S. Lee, Saurabh Kumar, Graham Hepworth, Jonathan M. Kalman, Karen Halloran

Publikováno v: Circulation: Arrhythmia and Electrophysiology. 5:1124-1129

Background— Catheter–tissue contact is critical for effective lesion creation. We characterized the contact force (CF) at different anatomic sites during antral pulmonary vein (PV) isolation for atrial fibrillation. Methods and Results— Two exp
