T. Ito et al., INFLUENCE OF ALTERED LOADING CONDITIONS ON LEFT ATRIAL APPENDAGE FUNCTION IN-VIVO, The American journal of cardiology, 81(8), 1998, pp. 1056
This study sought to examine the influence of heart failure treatment
on left atrial (LA) appendage function in 10 patients with left ventri
cular dysfunction. After treatment of heart failure, LA appendage func
tion markedly improved, less dependent on LA and left ventricular func
tions, which suggests that with altered loading conditions, LA appenda
ge function changes chiefly through its intrinsic contractile property
