Predicting adverse outcomes following catheter ablation treatment for atrial fibrillation [PDF]
, 2022 Objective: To develop prognostic survival models for predicting adverse outcomes after catheter ablation treatment for non-valvular atrial fibrillation (AF). Methods: We used a linked dataset including hospital administrative data, prescription medicine claims, emergency department presentations, and death registrations of patients in New South Wales,

Heart valve replacement during pregnancy [PDF]
, 2007 We describe a woman with gestational age of 20 weeks, who was submitted to a complex procedure. She underwent replacement of the biological mitral and aortic valve, both by biological prosthesis, valvuloplasty of the tricuspid valve, as well as ...

Fluid dynamics of heart valves during atrial fibrillation: a lumped parameter-based approach [PDF]
, 2015 Atrial fibrillation (AF) consequences on the heart valve dynamics are usually studied along with a valvular disfunction or disease, since in medical monitoring the two pathologies are often concomitant. Aim of the present work is to study, through a stochastic lumped-parameter approach, the basic fluid dynamics variations of heart valves, when only ...

NRC-Net: Automated noise robust cardio net for detecting valvular cardiac diseases using optimum transformation method with heart sound signals [PDF]
, 2023 Cardiovascular diseases (CVDs) can be effectively treated when detected early, reducing mortality rates significantly. Traditionally, phonocardiogram (PCG) signals have been utilized for detecting cardiovascular disease due to their cost-effectiveness and simplicity. Nevertheless, various environmental and physiological noises frequently affect the PCG

Non-invasive hemodynamic analysis for aortic regurgitation using computational fluid dynamics and deep learning [PDF]
arXiv, 2021 Changes in cardiovascular hemodynamics are closely related to the development of aortic regurgitation, a type of valvular heart disease. Metrics derived from blood flows are used to indicate aortic regurgitation onset and evaluate its severity. These metrics can be non-invasively obtained using four-dimensional (4D) flow magnetic resonance imaging (MRI)

Codec Data Augmentation for Time-domain Heart Sound Classification [PDF]
arXiv, 2023 Heart auscultations are a low-cost and effective way of detecting valvular heart diseases early, which can save lives. Nevertheless, it has been difficult to scale this screening method since the effectiveness of auscultations is dependent on the skill of doctors.

Targeted Estimation of Heterogeneous Treatment Effect in Observational Survival Analysis [PDF]
j.jbi.2020.103474, 2019 The aim of clinical effectiveness research using repositories of electronic health records is to identify what health interventions 'work best' in real-world settings. Since there are several reasons why the net benefit of intervention may differ across patients, current comparative effectiveness literature focuses on investigating heterogeneous ...

Substituição percutânea da válvula aórtica (TAVI) em doentes com estenose aórtica: revisão bibliográfica e análise da casuística do CHVNG [PDF]
, 2011 Introdução: A estenose valvular aórtica (EA) representa uma redução da área de abertura sistólica da válvula aórtica, sendo a EA degenerativa relacionada com a idade, a etiologia mais comum em adultos.
