A 33-year-old Algerian man presenting with acute asthma was found to have right bundle branch block and anterior ST-segment elevation on surface electrocardiogram (ECG). Two years earlier he had suffered a syncopal event during which relatives were unable find pulse. brother died suddenly asthma. Exercise tolerance …
The Biosense Webster ThermoCool® SmartTouch® Surround Flow (STSF) catheter is a recently developed ablation incorporating (SF) technology to ensure efficient cooling and force sensing quantify tissue contact. In our unit, it superseded the SF from time of its introduction in May 2015. Procedure-related data were collected prospectively for first 100 procedures performed department using STSF catheter. From database 654 unit catheter, we selected one match each procedure, matching procedure...
The use of remanufactured single-use devices (SUDs), including cardiac electrophysiology catheters, has become established in the USA and other health care systems but without much published scientific evaluation on relative safety or efficacy these devices. In United Kingdom (UK), SUDs not been routine. We performed a structured circular mapping catheter (Stryker® Lasso NAV 2515) during its introduction our centre.We prospectively evaluated performance 100 consecutive patients undergoing an...
To determine if a software algorithm can use an individualized distance-morphology difference model, built from three initial pacemaps, to prospectively locate the exit site (ES) of ventricular arrhythmias (VA).Consecutive patients undergoing ablation VA single centre were recruited. During mapping, pacing points collected in chamber interest and navigation applied predict ES, which was corroborated by conventional mapping techniques. Thirty-two underwent ES prediction over 35 procedures....
Abstract Funding Acknowledgements Type of funding sources: None. Background Bipolar radiofrequency catheter ablation (B-RFA) has shown promising results in refractory ventricular arrhythmia (VA) septal origin and underlying non-ischemic cardiomyopathy (NICM). However, its efficacy safety other locations such as the free wall papillary muscles (PM) not yet been fully determined. Purpose To describe analyse procedural data, B-RFA a cohort patients with VA different substrate. Methods We...
Abstract Background Cardiac perforation caused by cardiac rhythm device implantation is uncommon but potentially lethal. Methods All patients presenting to a single referral centre with after between December 2017 and July 2019 were identified. Patient demographics, time diagnosis, the method of lead extraction 30-day complications examined. Results Thirteen cases identified, 4 which implanted at other hospitals. The incidence for devices our institution was 9/1031 (0.87%). Median from...
Catheter ablation is widely used for the control of ventricular tachycardia (VT) in structural heart disease. Patients this group can be highly complex, with multiple comorbidities, and have often had prior cardiac surgery. Increasing numbers these patients are now being treated percutaneous options valve replacement/repair. As such, we seeing referred devices to our arrhythmia services who require catheter ablation. We present first reported case VT presence Tendyne mitral prosthesis...
Cardiac implantable electronic device (CIED)-related perforation is uncommon but potentially lethal. Management typically includes the use of computed tomography (CT) scanning and often involves cardiac surgery.Patients presenting to a single referral centre with CIED-related between 2013 2019 were identified. Demographics, diagnostic modalities, method lead revision, 30-day complications examined.A total 46 cases identified; median time from implantation diagnosis was 14 days (interquartile...
Abstract Funding Acknowledgements Type of funding sources: None. Background Cardiac perforation is an uncommon but life-threatening complication cardiac implantable electronic device (CIED) implantation. Management strategy commonly relies on diagnostic Computed Tomography (CT) imaging and surgery. Emerging evidence has indicated a diversion from this approach. Transvenous culprit lead revision been shown to be safe efficacious in limited series. We sought evaluate the outcomes transvenous...
