Immediate Improvement in Left Atrial Function After Transcatheter Aortic Valve Replacement on Doppler Echocardiography.

CONCLUSIONS: There is immediate improvement in LA function and an increase in LAA velocities after TAVR. This improvement may benefit hemodynamics immediately after TAVR, but may also increase the short-term stroke risk (as recently shown in two independent studies) in patients with LAA thrombus or low emptying velocities. Therefore, evaluation of LA function and LAA thrombus may be warranted to identify patients at high risk for periprocedural stroke and guide the need for anticoagulation therapy.
