Biotronik launches trial of CLS AF algorithm
Biotronik said today it enrolled the 1st patient in its B3 trial examining the company’s Closed Loop Stimulation physiologic rate response sensor and algorithm.
The study aims to whether pacemakers and implantable cardioverter-defibrillators equipped with the CLS sensor and algorithm are able to reduce the rate of stroke and improve outcomes in patients with atrial fibrillation compared to those without the system.
“AF is a huge clinical challenge, affecting over 20 million patients in Europe and the US alone. I am very excited to begin this groundbreaking trial. We hope to demonstrate that the physiological h...

Is FDA Getting More Cozy with AI?
The use of artificial intelligence (AI) is undoubtedly on the rise in healthcare. From fledging medtech companies to established giants like Watson IBM—many firms are riding the current AI wave. Not only are companies embracing technology, but so is FDA.
Recently the agency gave approval to San Francisco-based Viz.ai’s Contact application, a type of clinical decision support software designed to analyze CT results that could notify providers of a potential stroke in their patients. “What it’s doing is comparing the imaging features in that patient with the millions of images it has been trained on in the past, in...

337-i * thoracoscopic left atrial appendectomy
Conclusions: This approach demonstrated feasibility, safety and effectiveness and should be considered as a possible alternative to percutaneous closure of the LAA. However, its effect on long-term prevention of stroke needs to be evaluated.

FDA clears AliveCor ’ s KardiaBand ECG for Apple Watch
AliveCor said today that the FDA cleared its KardioBand electrocardiogram device for the Apple Watch, designed to monitor for early signs of atrial fibrillation.
First introduced in March 2016, KardiaBand is the first medical device accessory to be cleared by the federal safety watchdog for the Apple Watch, Mountain View, Calif.-based AliveCor said. It’s designed to display and record clinical-grade cardiac rhythm readings in real time in about 30 seconds, the company said.
AliveCor also said it launched the SmartRhythm artificial intelligence app for the Apple Watch, which is designed to continuously evaluate the ...

First results of the Brazilian Registry of Percutaneous Left Atrial Appendage Closure
Conclusions: In this multicenter, real world registry, that included patients with NVAF and high thromboembol ic and bleeding risks, LAAC effectively prevented stroke and bleeding when compared to the expected rates based on CHA2DS2VASc and HASBLED scores for this population. Complications rate of the procedure was acceptable considering the beginning of the learning curve of most of the involved operators.Resumo Fundamento: A oclus ão percutânea do apêndice atrial esquerdo (OAAE) é uma alternativa eficaz à anticoagulação oral (ACO) para a prevenção de acidente vascular cerebral (AVC) em pacientes com fibrilação...

Biosense Webster Unveils Late-Breaking Results from PRECEPT Study in Patients with Persistent Atrial Fibrillation
IRVINE, CA – May 8, 2020 – Johnson & Johnson Medical Devices Companies* today announced that Biosense Webster, Inc.’s THERMOCOOL SMARTTOUCH® SF Ablation Catheter, evaluated in the PRECEPT study for the treatment of persistent atrial fibrillation (AF), resulted in freedom from any documented, symptomatic atrial arrhythmias at 15 months post-procedure for eight out of ten study participants (80.4 percent).1 Use of the THERMOCOOL SMARTTOUCH SF CATHETER for persistent atrial fibrillation is investigational only. This PRECEPT study data support a Premarket Approval supplement application to the U.S. Food and Drug Adm...

Predicting patient-level new-onset atrial fibrillation from population-based nationwide electronic health records: protocol of FIND-AF for developing a precision medicine prediction model using artificial intelligence
Introduction
Atrial fibrillation (AF) is a major cardiovascular health problem: it is common, chronic and incurs substantial healthcare expenditure because of stroke. Oral anticoagulation reduces the risk of thromboembolic stroke in those at higher risk; but for a number of patients, stroke is the first manifestation of undetected AF. There is a rationale for the early diagnosis of AF, before the first complication occurs, but population-based screening is not recommended. Previous prediction models have been limited by their data sources and methodologies. An accurate model that uses existing routinely collected data is n...

Biosense Webster Launches the OCTARAY ™ Mapping Catheter with TRUEref™ Technology
IRVINE, CA – September 6, 2022 – Biosense Webster, Inc., part of Johnson & Johnson MedTech[†], today announced the release of the OCTARAY™ Mapping Catheter with TRUEref™ Technology powered by the CARTO™ 3 Version 7 System. The OCTARAY™ Mapping Catheter was developed for the mapping of cardiac arrhythmias, including atrial fibrillation (AFib). The catheter has eight splines with improved electrode spacing options to provide shorter and more efficient mapping times than PENTARAYTM NAV ECO Mapping Catheter, which may shorten overall ablation procedure times.[2],[8],[‡] AFib is the most common type of cardi...

Automatic Segmentation of the Left Atrium from Computed Tomography Angiography Images
Ann Biomed Eng. 2023 Mar 8. doi: 10.1007/s10439-023-03170-9. Online ahead of print.ABSTRACTThe left atrial appendage (LAA) causes 91% of thrombi in atrial fibrillation patients, a potential harbinger of stroke. Leveraging computed tomography angiography (CTA) images, radiologists interpret the left atrium (LA) and LAA geometries to stratify stroke risk. Nevertheless, accurate LA segmentation remains a time-consuming task with high inter-observer variability. Binary masks of the LA and their corresponding CTA images were used to train and test a 3D U-Net to automate LA segmentation. One model was trained using the entire un...
