Key result
Obesity in VT ablation is linked to longer stays and more pericardial effusions, with similar mortality.
Why the study?
Evidence on the impact of obesity on catheter ablation for ventricular tachycardia was scarce.
Does obesity increase the risk of adverse in-hospital outcomes and 30-day readmissions in patients undergoing catheter ablation for ventricular tachycardia?
Observational
Yes
Does obesity increase the risk of adverse in-hospital outcomes and 30-day readmissions in patients undergoing catheter ablation for ventricular tachycardia?
Catheter ablation for ventricular tachycardia can be performed relatively safely in obese patients, though it is associated with longer hospital stays, higher costs, and slightly higher rates of specific procedural complications.
Supports heightened periprocedural vigilance for effusion and LOS in obese VT ablation patients; leaves open causal impact pending prospective data.
Background Evidence on the impact of obesity on catheter ablation for ventricular tachycardia (VT) is scarce. Method and Results We queried the Nationwide Readmissions Database to determine the hospital outcomes and procedural complications of VT ablation among the obese and nonobese populations. Obesity was associated with a more prolonged length of stay (p < .01), higher cost of hospitalization (p < .01), and higher rates of pericardial effusion or hemopericardium (p = .05) and vascular complications (p = .05). There was no significant difference in early mortality, 30‐day readmissions, and other procedural complications. Conclusion VT ablation could be performed relatively safely among patients with obesity.

Tan et al. (2023) conducted an observational in Ventricular tachycardia. Obesity vs. Nonobese population was evaluated on Hospital outcomes and procedural complications. Obesity in patients undergoing ventricular tachycardia ablation was associated with prolonged length of stay (p<0.01) and higher rates of pericardial effusion (p=0.05), with no difference in mortality.
