Diagnostic accuracy of artificial intelligence-based electrocardiogram algorithm to predict heart failure with reduced ejection fraction: a systematic review and meta-analysis

Circulation; 150 (Suppl. 1), 2024
INTRODUCTION: AI-based EKG has shown good accuracy for diagnosing heart failure. However, due to the heterogeneity of studies regarding cutoff points, its precision for specifically detecting heart failure with reduced ejection fraction (LVEF <40%) is not yet well established. Research question: What it ...

Comparative analysis of classical artificial intelligence and deep learning models for atrial fibrillation detection in electrocardiograms

Europace; 26 (Suppl. 1), 2024
BACKGROUND/INTRODUCTION: Early diagnosis of atrial fibrillation (AF) presents a challenging yet critical task for appropriate interventions aimed at reducing disease-related burden. In this context, strategies employing classical artificial intelligence (CAI) and deep learning (DL) have emerged as promis...

Seguimento dos pacientes com síndrome arritmogênica do prolapso valvar mitral após implante de cardioversor desfibrilador implantável
Follow-up of patients with arrhythmogenic mitral valve prolapse syndrome after implantable cardioverter defibrillator implantation

Int. j. cardiovasc. sci. (Impr.); 37 (suppl.9), 2024
INTRODUÇÃO: A síndrome arritmogênica do prolapso valvar mitral (PVM) é uma condição associada a eventos arrítmicos ventriculares e morte súbita cardíaca (MSC). O acompanhamento por telemetria do cardioversor-desfibrilador implantável (CDI) pode aprimorar a compreensão dessa síndrome por ser ...

Ablação de via acessória lateral esquerda em criança com obstrução de veia cava inferior: relato de caso
Ablation of the left lateral accessory pathway in a child with inferior vena cava obstruction: case report

Int. j. cardiovasc. sci. (Impr.); 37 (suppl.9), 2024
ILCF, 5anos, 15,5Kg, 1,05m (fig), com diagnóstico de taquicardia por reentrada atrioventricular ortodrômica incessante associada a disfunção ventricular esquerda por taquicardiomiopatia, foi submetida a ablação aos 6meses de idade, interrompida por espasmo de artéria circunflexa, insuficiência mi...

Conduction disturbances and permanent pacemaker implantation after myval transcatheter heart valve or contemporary standard valves (Sapien and Evolut) implantation: insights from the LANDMARK Trial

J. Am. Coll. Cardiol; 84 (18 Suppl. B), 2024
BACKGROUND LANDMARK was a multicenter randomized trial that demonstrated noninferiority of the Myval balloon-expandable trans. catheter heart valve (THV) compared with the contemporary THVs (Sa- pien and Evolut series) at 30 days in patients with severe aortic stenosis. METHODS From January 2021 to Decem...

Predictors of conduction system disturbances resulting in a new permanent pacemaker implantation within the Landmark Trial

J. Am. Coll. Cardiol; 84 (18 Suppl. B), 2024
BACKGROUND The need for permanent pacemaker implantation (PPMI) after transcatheter aortic valve implantation (TAVR) is a serious complication that adds additional risk for the patient. It also lengthens the hospitalization and increases costs. Unknown is the PPMI rate of the new balloon expandable Myval...

Refining ECG interpretation: from false assumptions to evidence-based precision

J. eletrocardiol; 87 (), 2024
INTRODUCTION: Electrocardiography (ECG) remains a fundamental tool in cardiovascular diagnostics, frequently relying on System 1 thinking-rapid, intuitive pattern recognition (PR). However, this approach can be insufficient when dealing with complex cases where diagnostic precision is essential. This art...

Cardiomiopatia de Takotsubo associada a feocromocitoma: um caso atípico e complexo
Takotsubo cardiomyopathy associated with pheochromocytoma: an atypical and complex case

Arq. bras. cardiol; 121 (9 supl.1), 2024
INTRODUÇÃO Cardiomiopatia (CMP) induzida por estresse, como a cardiomiopatia de Takotsubo, pode ter características clínicas semelhantes à isquemia miocárdica, como elevação de troponinas, alterações no Eletrocardiograma (ECG), mas sem obstrução coronariana ou lesões isquêmicas. Semelhante,...

Poor evidence for poor R wave progression in coronary disease: a scoping review

J. eletrocardiol; 84 (), 2024
BACKGROUND Poor R wave progression (PRWP) and reversed R wave progression (RRWP) have long been noted in electrocardiograms as potential indicators of anterior wall fibrosis or chronic coronary artery disease; however, the quantity and quality of evidence supporting these associations warrants closer exa...
