EXCLUSION OF LEFT ATRIAL APPENDAGE THROMBUS WITH DOBUTAMINE INFUSION PRIOR TO CARDIOVERSION IN PATIENTS WITH ATRIAL FIBRILLATION AND DENSE SPONTANEOUS ECHO CONTRAST

Abstract

Spontaneous echo contrast (SEC) in the left atrial appendage (LAA) is often seen in patients with atrial fibrillation and low LAA emptying velocities. Because transesophageal echocardiography (TEE) may not be able to differentiate between dense SEC and thrombus, direct current cardioversion (DCCV)
