Atrial Thrombus Exclusion (ATE) Score Diagnostic Accuracy for Predicting the Absence of Intra-Atrial Thrombi Before AF Ablation
Authors' conclusion
In patients hospitalized for catheter ablation of AF or LAT, the ATE score identifies a population at very low risk for atrial thrombus.
Study context
- Population
- Patients hospitalized for catheter ablation of AF or left atrial tachycardia (LAT)
- Participants
- 3,072 patients
- Comparison
- ATE score of 0 vs transesophageal echocardiography (TEE) for excluding atrial thrombus
- Outcome
- Presence of atrial thrombus diagnosed by TEE
Methodological detailsprospective, multicentre, consecutive patients
- Prospective
- Multicentre
- Consecutive patients
