The Claim
Among patients with structural heart disease undergoing combined endocardial and epicardial ventricular tachycardia ablation, 50% experienced ventricular tachycardia recurrence during a median 17-month follow-up period.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In patients with structural heart disease who underwent a complex heart rhythm procedure targeting ventricular tachycardia, half of them had the abnormal heart rhythm return within about 17 months.
See the scientific wording
Among patients with structural heart disease undergoing combined endocardial and epicardial ventricular tachycardia ablation, 50% experienced ventricular tachycardia recurrence during a median 17-month follow-up, indicating that even aggressive ablation strategies yield only moderate long-term success.
After ablation, some areas of heart tissue that trigger dangerous rhythms are not fully destroyed, leaving behind patches of living muscle that can still generate abnormal electrical signals. These leftover areas reconnect with surrounding scar tissue, creating pathways that let electrical impulses loop and restart dangerous rhythms.
What the research says
1 studyEven after a thorough heart procedure to stop dangerous rhythms, half the patients had the rhythm come back within about a year and a half — which means the treatment helps, but doesn’t fix the problem for most people long-term.
