Implication
May aid TTE-based LAA thrombus detection in non-valvular AF; leaves open whether it refines stroke risk stratification or anticoagulation decisions.
Structured PICO
Which method of left atrium size quantification is the most accurate to recognize thromboembolic risk in patients with non-valvular atrial fibrillation?
P
Population
500 consecutive patients undergoing transthoracic and transesophageal echocardiography evaluation during a non-valvular atrial fibrillation episode
I
Intervention
Left atrial size measurement on transthoracic echocardiography using several methods (anteroposterior diameter, area in four-chamber view, and volumes by the ellipsoid, single- and biplane area-length formulas)
C
Comparator
Comparison between different methods of left atrial size quantification
O
Outcome
Accuracy of left atrial size to identify surrogate markers of increased thromboembolic risk (LAA thrombus, LAA low flow velocities, dense spontaneous echocardiographic contrast, and LA abnormality) evaluated by transesophageal echocardiographysurrogate
Indexed left atrial area in the four-chamber view and indexed area-length volumes are the most accurate transthoracic echocardiographic methods for identifying surrogate markers of stroke in patients with non-valvular atrial fibrillation.
