Does color Doppler tissue imaging identify left atrial appendage dysfunction in acute myocardial infarction patients with spontaneous echo contrast or thrombus?

Population

84 patients with acute myocardial infarction, divided into those with (n=24, mean age 59 +/- 12 years) and without (n=60, mean age 58 +/- 8 years) spontaneous echo contrast (SEC) and/or thrombus in the left atrial appendage.

Intervention

Transesophageal color Doppler tissue imaging (CDTI) and transesophageal Doppler echocardiography

Comparator

Comparison between patients with SEC and/or thrombus (Group 1) versus those without (Group 2)

Outcome

Left atrial appendage function, including LAA emptying velocity, LAA filling velocity, and systolic appendage tissue velocities (SaV)surrogate

Color Doppler tissue imaging can quantitatively assess regional LAA systolic function, demonstrating decreased velocities in patients with LAA thrombus or spontaneous echo contrast.
