A Novel SCN5A Mutation in a Patient with Coexistence of Brugada Syndrome Traits and Ischaemic Heart Disease

Case Reports in Medicine, 2009
Brugada syndrome (BrS) is a primary electrical heart disease, which can lead to sudden cardiac death. In older patients with BrS, the disease may coexist with ischaemic heart disease (IHD) and recent studies support a synergistic proarrhythmic effect of ...

Quantitative Regular Expressions for Arrhythmia Detection Algorithms [PDF]

arXiv, 2016
Motivated by the problem of verifying the correctness of arrhythmia-detection algorithms, we present a formalization of these algorithms in the language of Quantitative Regular Expressions. QREs are a flexible formal language for specifying complex numerical queries over data streams, with provable runtime and memory consumption guarantees. The medical-

Genetic causal association between heart failure, frailty and poisoning by narcotics and psychodysleptics: A two‐sample Mendelian randomization

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aims Observational studies have suggested associations between heart failure (HF), frailty and poisoning by narcotics and psychodysleptics (PNP). However, establishing causal relationships has been challenging. This study used a two‐sample Mendelian randomization (MR) approach to investigate the genetically proxied causality between HF ...

Ethnomedicinal Uses, Phytochemistry, Pharmacological Activities, and Toxicology of the Subfamily Gomphrenoideae (Amaranthaceae): A Comprehensive Review

Chemistry &Biodiversity, EarlyView.
ABSTRACT The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its ...

An eikonal model with re-excitability for fast simulations in cardiac electrophysiology [PDF]

arXiv
Precision cardiology based on cardiac digital twins requires accurate simulations of cardiac arrhythmias. However, detailed models, such as the monodomain model, are computationally costly and have limited applicability in practice. Thus, it desirable to have fast models that can still represent the main physiological features presented during cardiac ...

Steerable Delivery Sheath for Optimized LAA Closure: First Experience and Procedural Outcomes

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The new Amplatzer Steerable Delivery Sheath is a delivery system designed to improve ease‐of‐use and procedural results of left atrial appendage closure (LAAC). We aimed to compare procedural results after switching our LAAC program at a tertiary care center with the Amulet device to the Steerable Delivery Sheath, with a control ...

Cardiac resynchronization therapy in heart failure based on Strauss criteria for left bundle branch block

ESC Heart Failure
Aims The left bundle branch block (LBBB) is a strong predictor of response to cardiac resynchronization therapy (CRT). However, a significant number of patients do not respond to the treatment.

Novel Transthoracic Pulmonary Valve Implantation Using Self‐Expanding Salus Valve: A Prospective Study of Safety and Mid‐Term Outcomes

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter pulmonary valve replacement (TPVR) has emerged as a valuable treatment for severe pulmonary regurgitation (PR). The Salus valve (Balance Medical Technology Co. Ltd., Beijing, China) represents a novel self‐expanding valve stent designed for deployment through a transthoracic approach with a small subxiphoid incision ...

The Subtle Journey of a Right Atrial Lead

JACC: Case Reports, 2020
We report an unusual case of subacute right atrial perforation by a screw-in pacemaker lead that migrated into the right lung causing hemopneumothorax 2 weeks after the procedure. After transvenous simple manual traction and minithoracotomy repair of the
