Catheter ablation versus medical therapy for atrial fibrillation in patients with heart failure with preserved ejection fraction: a systematic review and meta-analysis

Heart rhythm; 21 (9), 2024
BACKGROUND The benefit of catheter ablation in patients with atrial fibrillation (AF) for patients with heart failure with preserved ejection fraction (HFpEF) remains uncertain. OBJECTIVE We conducted a systematic review and meta-analysis to compare catheter ablation and medical therapy (antiarrhythmics ...

Prolonged use of intra-aortic balloon pump in patients awaiting heart transplantation: a safe strategy?

Eur. j. heart fail. Suppl; 26 (Suppl. S2), 2024
BACKGROUND/INTRODUCTION: Heart transplantation (HT) is a therapeutic strategy used in patients with advanced heart failure (AHF) who remain symptomatic despite optimized clinical treatment and may be dependent on inotropic agents to maintain hemodynamic stability. A very delicate scenario is the patient ...

Reply to the editor- clinical potential of conduction system pacing versus biventricular pacing in heart failure: a trial sequential analysis and methodological comment

Heart rhythm; 21 (7), 2024
We thank Romeiro et al for their letter. Although we generally agree with the limited performance of funnel plots when the number of included studies is low, this systematic review and meta-analysis aimed to summarize the totality of published randomized controlled trials on conduction system pacing vs b...

Trinta anos de evolução de transplante cardíaco ortotópico: relato de caso
Thirty years of evolution of orthotopic heart transplantation: case report

Int. j. cardiovasc. sci. (Impr.); 37 (suppl.1), 2024
INTRODUÇÃO: O transplante cardíaco (Tx) é a opção terapêutica de escolha para o tratamento da insuficiência cardíaca grave apesar do tratamento clínico otimizado. Está associado à sobrevida média de 12 anos. Complicações precoces como falência do enxerto, infecções oportunísticas e rej...

Pericardite crônica constritiva de etiologia incomum: um relato de caso
Chronic constrictive pericarditis of uncommon etiology: a case report

Int. j. cardiovasc. sci. (Impr.); 37 (suppl.1), 2024
INTRODUÇÃO: Várias etiologias podem levar à inflamação pericárdica, sendo as mais frequentes a tuberculosa e viral. O pericárdio inflamado e também o processo reparativo incluindo fibrose e espessamento subsequente estão relacionados a quadros de constricção e insuficiência cardíaca. Descre...

Fatores contribuintes para doença renal crônica em pacientes com insuficiência cardíaca com fração de ejeção preservada
Contributing factors to chronic kidney disease in patients with heart failure with preserved ejection fraction

INTRODUÇÃO: A insuficiência cardíaca com fração de ejeção preservada (ICFEP) aumenta significativamente o risco de desenvolvimento de doença renal crônica (DRC), afetando adversamente desfechos clínicos como mortalidade prematura, morbidade, complicações multiorgânicas e custos de saúde. E...

Embedded cyber-physical system for physiological control of ventricular assist devices

Ventricular Assist Devices (VADs) play a crucial role in both bridging to transplantation and serving as destination therapy for congestive heart failure (CHF) management. This study aims to address the limitations of existing control strategies for VADs, specifically their inability to adapt automatical...

Conduction system pacing versus biventricular pacing in heart failure with reduced ejection fraction: a systematic review and meta-analysis of randomized controlled trials

Heart rhythm; 21 (6), 2024
Conduction system pacing (CSP) has emerged as a promising alternative to biventricular pacing (BVP) heart failure patients with reduced ejection fraction (HFrEF) and ventricular dyssynchrony, but its benefits are still uncertain. In this study, we aim to evaluate clinical outcomes of CSP versus BVP for c...
