Outcomes of Mapping and Catheter Ablation Techniques For the Treatment of VT Session

Video Transcription

Video Summary

The study aimed to examine the safety and outcomes of ventricular tachycardia (VT) ablation across different age groups. The researchers used the National Inpatient Sample (NIS) database, which contains data from hospital stays in the United States, covering 97% of the population. They identified patients over the age of 21 who underwent VT ablation and divided them into four age groups: 20-39, 40-59, 60-79, and over 80. The primary outcome was all-cause mortality, and secondary outcomes included transfer to rehab, hospital length of stay, and in-hospital complications. The study found no significant differences in complications or hospital length of stay across age groups. However, mortality rates were significantly higher in octogenarians (over 80) compared to the other age groups. Additionally, transfer to rehab was more common in the older age groups. The researchers concluded that while VT ablation appears to be safe across age groups, mortality rates are higher in octogenarians. This study provides insights into the outcomes of VT ablation in different age groups and highlights the need for careful patient selection, particularly in very elderly patients.
