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 ...

Progression and prognostic significance of electrocardiographic findings in patients with cardiac amyloidosis

ESC Heart Failure, Volume 12, Issue 2, Page 809-818, April 2025.
Abstract Aims This study aimed to evaluate the change of the main electrocardiographic (ECG) characteristics and their prognostic role across the main subtypes of cardiac amyloidosis [light‐chain amyloidosis (AL) and hereditary (ATTRv) and wild‐type transthyretin amyloidosis (ATTRwt)].

eGFR slope as predictor of mortality in heart failure patients

ESC Heart Failure, Volume 12, Issue 2, Page 1217-1226, April 2025.
Abstract Aims Heart failure (HF) leads to an imbalance between heart and kidney function, resulting in poor outcomes. However, the prognostic significance of the estimated glomerular filtration rate (eGFR) trajectory in HF patients remains unclear. We analysed electronic health records (EHRs) of real‐world HF patients, assessing eGFR trajectories and ...

Incidence of atrial fibrillation in patients with an insertable cardiac monitor and symptomatic heart failure

ESC Heart Failure, Volume 12, Issue 3, Page 1693-1702, June 2025.
Atrial fibrillation (AF) was observed in almost half of patients with insertable cardiac monitor and symptomatic heart failure (HF). One‐fourth of the patients had new onset AF and a higher rate of HF events compared with patients without AF. AF incidence was similar in HF patients with preserved versus reduced left ventricular ejection fraction ...

Prediction of 90 day mortality in elderly patients with acute HF from e‐health records using artificial intelligence

ESC Heart Failure, Volume 12, Issue 3, Page 2200-2209, June 2025.
Abstract Aims Mortality risk after hospitalization for heart failure (HF) is high, especially in the first 90 days. This study aimed to construct a model automatically predicting 90 day post‐discharge mortality using electronic health record (EHR) data 48 h after admission and artificial intelligence. Methods All HF‐related admissions from 2015 to 2020

Limit Cycle Oscillations in Pacemaker Cells [PDF]

arXiv, 1999
In recent decades, several mathematical models describing the pacemaker activity of the rabbit sinoatrial node have been developed. We demonstrate that it is not possible to establish the existence, uniqueness, and stability of a limit cycle oscillation in those models. Instead we observe an infinite number of limit cycles.

Pacemaker: Intermediate Teacher Knowledge Distillation For On-The-Fly Convolutional Neural Network [PDF]

arXiv, 2020
There is a need for an on-the-fly computational process with very low performance system such as system-on-chip (SoC) and embedded device etc. This paper presents pacemaker knowledge distillation as intermediate ensemble teacher to use convolutional neural network in these systems. For on-the-fly system, we consider student model using 1xN shape on-the-

Cardiac rhythm devices in heart failure with reduced ejection fraction – role, timing, and optimal use in contemporary practice. European Journal of Heart Failure expert consensus document

European Journal of Heart Failure, EarlyView.
Abstract Guidelines for management of heart failure with reduced ejection fraction (HFrEF) emphasize personalized care, patient engagement, and shared decision‐making. Medications and cardiac rhythm management (CRM) devices are recommended with a high level of evidence. However, there are significant disparities: patients who could benefit from devices

Comparison of Benefits from Cardiac Resynchronization Therapy between Patients with Ischemic Cardiomyopathy and Patients with Idiopathic Dilated Cardiomyopathy [PDF]

Journal of Tehran University Heart Center, 2009
Background: Cardiac resynchronization therapy (CRT) is an effective treatment for patients with moderate to severe heart failure. However, 20-30% of patients remain non-responders to CRT.

Result of a British Survey on Artificial Cardiac Pacemakers [PDF]

BMJ, 1968
The use of cardiac pacemakers in the treatment of patients with complete heart block has increased greatly over the past two years in the United States, France, Germany, and Scandinavia and to a less extent also in the British Isles. In order to obtain some basic data concerning the clinical situation and perform ance of pacemakers in Britain a survey ...
