• The preventive effect of sodium-glucose co-transporter-2 inhibitors on life-threatening arrhythmias in patients with chronic kidney disease: a meta-analysis (2026) · doi

  There are several limitations in our meta-analysis. First, all arrhythmic events were reported as adverse events rather than primary or secondary outcomes, which may lead to under- reporting bias. Second, patient-level data were not available, and not all trials reported baseline comorbidity and background

• Efficacy and safety of electrical cardioversion and catheter ablation during pregnancy: a case review and literature analysis (2026) · doi

  The low incidence of arrhythmias necessitating electrical cardioversion or catheter ablation during pregnancy inherently limited the sample size. While this accurately mirrors real-world clinical practice, the interpretation of findings warrants caution due to potential selection bias and the lack of comparator groups. The existing evidence consists of case reports spanning several decades, with the majority published post-2000, and these methodological variations in reporting appear to have minimal impact on primary outcome assessments.

• Pregnancy and Delivery in a 27-Year-Old ICD Carrier (2021) · doi

  Despite this tendency, there are only a few reported cases of pregnancies in implantable cardiac defibrillator carriers, leading to insufficient evidence and clear guideline recommendations on how to manage and monitor pregnancy in patients with this type of cardiac pathology.
