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 ...

Cardioneuroablation in patients with vasovagal syncope: an updated systematic review and meta-analysis

Heart rhythm; (), 2024
BACKGROUND Cardioneuroablation (CNA) is a novel procedure that shows promising results in reducing syncope recurrence in patients with refractory vasovagal syncope (VVS). However, its effectiveness and safety remain controversial. OBJECTIVE We conducted an updated meta-analysis evaluating CNA efficacy an...

Effect of catheter ablation versus medical therapy on mental health and quality of life in patients with atrial fibrillation: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND: The association between atrial fibrillation (AF) and mental health is well-documented, but the relative benefits of catheter ablation versus medical therapy on mental health and quality of life are not clearly understood. This study assesses the impact of these interventions on AF patients' m...

Ablação de fibrilação atrial combinada com ablação de septo por radiofrequência: a importância do substrato estrutural
Atrial fibrillation ablation combined with radiofrequency septal ablation: the importance of structural substrate

Int. j. cardiovasc. sci. (Impr.); 37 (suppl.1), 2024
INTRODUÇÃO: A cardiomiopatia hipertrófica (CMH) pode apesentar, como consequência de alterações estruturais e fisiopatológicas dessa prevalente cardiopatia, a fibrilação atrial (FA) e a obstrução de via de saída de ventrículo esquerdo (VSVE), conferindo maior morbimortalidade ao paciente. As...

Cardioneuroablation for reflex syncope: a systematic review and single-arm meta-analysis

J. Am. Coll. Cardiol; 83 (13 Suppl. A), 2024
BACKGROUND: Reflex syncope reduces quality of life and leads to fall-related injuries, with no highly effective treatment. In this context, cardioneuroablation (CNA) presents as a promising therapy for these patients. METHODS: We searched PubMed, Embase and Cochrane Central for studies that evaluated saf...

Eficácia do sacubitril-valsartana comparado com IECA ou BRA para prevenir a recorrência de FA após ablação por cateter: uma meta-análise
Efficacy of sacubitril-valsartan compared with ACE inhibitors or ARBs to prevent AF recurrence after catheter ablation: a meta-analysis

INTRODUÇÃO: Em pacientes que foram submetidos a ablação por cateter devido a fibrilação atrial pode ocorrer a recorrência deste quadro. Não é estabelecido o efeito do S/V na prevenção da recorrência de fibrilação atrial (FA) comparado a Inibidores da Enzima Conversora da Angiotensina (IECA)...

Safety and efficacy of catheter ablation for atrial fibrillation in cancer survivors: a systematic review and meta-analysis

BACKGROUND: Cancer survivors are at increased risk for atrial fibrillation (AF). However, data on the efficacy and safety of catheter ablation (CA) in this population remain limited. Therefore, we aimed to perform a systematic review and meta-analysis comparing outcomes after CA for AF in patients with v...

Safety and efficacy of catheter ablation for atrial fibrillation in patients with a history of cancer: a systematic review and meta-analysis

Circulation; 148 (Suppl.1), 2023
BACKGROUND: Patients with an active or past medical history of cancer have an increased risk of atrial fibrillation (AF) and drug-refractory AF. However, evidence for the safety and efficacy of catheter ablation in this population remains limited. HYPOTHESIS: Catheter ablation is a safe and effective str...

Ablação septal por radiofrequência no tratamento da cardiomiopatia hipertrófica obstrutiva: experiência de serviço terciário
Radiofrequency septal ablation in the treatment of obstructive hypertrophic cardiomyopathy: experience of a tertiary service

INTRODUÇÃO: A cardiomiopatia hipertrófica obstrutiva (CMHO) pode estar associada a sintomas limitantes de qualidade de vida, refratários à terapêutica otimizada. A terapia de redução septal (TRS) está indicada nestes pacientes, quando há gradiente de via de saída do ventrículo esquerdo (GVSVE...

Ablação septal com radiofrequência em paciente com obstrução dinâmica na via de saída do ventrículo esquerdo associado a pós operatório de cardiopatia congênita: relato de caso
Septal ablation with radiofrequency in a patient with dynamic obstruction in the left ventricular outflow tract associated with postoperative congenital heart disease: case report

INTRODUÇÃO: A obstrução da via de saída do ventrículo esquerdo (VSVE) é uma condição frequentemente descrita nos casos de cardiomiopatia hipertrófica obstrutiva (CMHO), gerando comprometimento da classe funcional, além de associação com morte súbita. Em pós- -operatório de cardiopatias co...
