Summary

This study tested whether a simple scoring system (ATE score) can safely rule out dangerous blood clots in the heart before a procedure for atrial fibrillation. Over 3,000 adults participated. The goal was to see if the score could replace a more uncomfortable ultrasound test, potentially making preparation for treatment easier and less invasive.

Who is studied

In agreement with the physician performing the procedure, the study will be explained and proposed to the eligible patients by an investigator at the admission or at the pre-ablation consultation. It is strongly recommended to include patients consecutively in order to limit selection bias.
