111 Safety and efficacy of very high-power short duration radiofrequency ablation in a UK cohort using the QDOT micro catheter

Kiran Kang, Sarah Zeriouh, Sharad C Agarwal, Munmohan Virdee et autres

Introduction Radiofrequency (RF) is a widely used technology for Atrial Fibrillation (AF) ablation. However, settings for optimal lesion geometry to obtain transmural, durable, and safe lesions are still debated. High Power Short Duration (HPSD) is a novel strategy aiming to create more …

Novel aggregated multiposition noncontact mapping of atrial tachycardia in humans: From computational modeling to clinical validation

Rui Shi, Junaid A.B. Zaman, Zhong Chen, Xinwei Shi et autres

BACKGROUND: A novel aggregated multiposition noncontact mapping (AMP-NCM) algorithm is proposed to diagnose cardiac arrhythmias. OBJECTIVE: The purpose of this study was to computationally determine an accuracy threshold and to compare the accuracy and clinical utility of AMP-NCM to gold standard contact …

99 Pulmonary vein isolation for atrial fibrillation: ice ‘block’ vs ring of fire

Ashwin Reddy, Sarah L. Nethercott, Bharat Vashdev Khialani, Munmohan Virdee

Background Over the last 20 years various techniques have been developed striving for safer and more durable pulmonary vein isolation (PVI). The popularity and uptake of ‘single-shot’ strategies, which by their nature are simpler and quicker, has risen in line with the …

Subacute asymptomatic right ventricular lead perforation complicated with ipsilateral pneumothorax after lead reposition

Bruna Costa Lemos Silva Di Nubila, Munmohan Virdee

Major advancements have been made in the design of pacing leads to improve electrical performance and patient safety. However, lead perforation is still seen with an incidence of 0.1–0.8%. A 77-year-old woman with the diagnosis of right ventricular (RV) lead perforation after …

46 Feasibility and economic implications of ambulatory af ablation: a single-centre experience

Sathineni Ashwin Reddy, Sarah L. Nethercott, Mohammed Farag, Rahul Kumar Chattopadhyay et autres

Introduction The widely accepted model for AF ablation involves overnight hospital stay post-procedure. Given the rising incidence of AF and number of AF ablations performed, streamlining of practice to minimise overnight stay could result in a significant reduction in waiting list times …

Very long-term survival and late sudden cardiac death in cardiac resynchronization therapy patients

Sérgio Barra, Rudolf Martin Duehmke, Rui Andre Providencia, Kumar Narayanan et autres

AIMS: The very long-term outcome of patients who survive the first few years after receiving cardiac resynchronization therapy (CRT) has not been well described thus far. We aimed to provide long-term outcomes, especially with regard to the occurrence of sudden cardiac death …

Sudden-onset severe presyncope in a 67-year-old man

K Sanders, Claire Martin, Munmohan Virdee

A 67-year-old man presented to the emergency department with sudden onset of severe presyncope. He reported that he had a permanent pacemaker implanted in 2006 following atrioventricular node ablation for persistent atrial fibrillation (AF). After suffering increasing shortness of breath, he underwent …

Device complications with addition of defibrillation to cardiac resynchronisation therapy for primary prevention

Sérgio Barra, Rui Andre Providencia, Serge Bovéda, Rudolf Martin Duehmke et autres

OBJECTIVE: In patients indicated for cardiac resynchronisation therapy (CRT), the choice between a CRT-pacemaker (CRT-P) versus defibrillator (CRT-D) remains controversial and indications in this setting have not been well delineated. Apart from inappropriate therapies, which are inherent to the presence of a …

Do women benefit equally as men from the primary prevention implantable cardioverter-defibrillator?

Sérgio Barra, Rui Andre Providencia, Serge Bovéda, Kumar Narayanan et autres

Women traditionally have been and are still underrepresented in research in many important areas of cardiology, and guideline recommendations which also encompass women are mostly based on research conducted predominantly in men. However, there is plausible cause to believe that sex may …

34 Use of general anaesthesia in catheter ablation of persistent af: improved outcome and cost effectiveness

Claire Martin, James P. Curtain, Parag Ravindra Gajendragadkar, David Begley et autres

Introduction The outcome of persistent atrial fibrillation (PeAF) ablation remains suboptimal and procedures may be long and painful. Little evidence is available on outcome for procedures under general anaesthetic (GA) compared to conscious sedation (CS). We performed a single-centre observational study to …

35 Uk multi-centre registry of transvenous lead extraction: clinical outcome using different techniques

Claire Martin, Bashistraj Chooneea, Parag Ravindra Gajendragadkar, Syed Ahsan et autres

Introduction With increasing numbers and complexity of implantable devices, the need for lead extraction is also increasing. There is little UK data available on clinical outcomes. We compiled a multi-centre registry of patients undergoing lead extraction to investigate predictors of success and …
