[Abstract only] Preliminary study suggests age-adjusted D-dimer can exclude left atrial thrombus in patients with atrial fibrillation

D-dimer blood concentrations to exclude left atrial thrombus in patients with atrial fibrillation – Heart (link to abstract – $ for full-text)

Commentary on Twitter

A nice study on the use of D-dimer for excluding left atrial thrombus.

Patients with D-dimer < (10 x patient's age) had 100% sensitivity and NPV for excluding LA thrombus.

This represented 60% of the population, who could in theory safely avoid TOE. https://t.co/OFUy9caWd0
