Comparing pulsed field ablation with very high-power and high-power short-duration radiofrequency ablation for atrial fibrillation: a systematic review and meta-analysis.

Background: Catheter ablation is a key treatment for atrial fibrillation (AF), with high-power, very high-power short-duration and pulsed field ablation (PFA) being efficient options. However, direct comparisons between these techniques are lacking.

Objective: We performed a systematic review and meta-analysis, which included predominantly observational studies (four retrospective and one prospective study), to compare PFA and High-power short-duration (HPSD) and very high-power short-duration (vHPSD) radiofrequency (RF) ablation in patients with AF.

The cardiotoxic effects of CAR-T cell therapy: An updated systematic review and meta-analysis.

Background: Chimeric antigen receptor T-cell (CAR-T) therapy has shown promise in treating hematologic malignancies, yet its potential cardiotoxic effects require thorough investigation.

Objectives: We aim to conduct a systematic review and meta-analysis to examine the cardiotoxic effects of CAR-T therapy in adults with hematologic malignancies.

Methods: We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials for studies reporting cardiovascular outcomes, such as arrhythmias, heart failure, and reduced left ventricle ejection fraction (LVEF).
