To describe a real-world cohort of ICD patients hospitalized with VT and explore differences between patients undergoing ablation and those managed conservatively.
Approach:
Study Design: Retrospective analysis of the VIDEO registry, which includes routinely collected administrative and clinical data from 13 centers in Germany.
Patient Selection: Included 801 ICD patients with documented VT, categorizing them based on whether they underwent VT ablation.
Data Collection: Anonymized data collected from January 2018 to December 2023, including patient characteristics, hospital stay duration, and comorbidities.
Statistical Analysis: Used Pearson’s chi-square test or Wilcoxon rank-sum test for comparisons; data managed with SAS software.
Key Findings:
18% of patients underwent VT ablation.
Mean age of the cohort was 63.3 years, with no significant age difference between groups (p = 0.22).
Lower prevalence of diabetes and chronic kidney disease in the ablation group (p values needed).
Patients with ablation had fewer instances of ischemic heart disease and mental disorders (p values needed).
Lower rates of ventricular flutter/fibrillation and cardiac arrest in the ablation group (p values needed).
Interpretation:
Limitations:
Retrospective nature may limit causal inferences.
Data may not reflect the primary reason for admission due to administrative coding.
