Echocardiographic variables of left atrial size and left auricular function pre- and post-trazodone in 12 healthy cats

Variable	Pre-trazodone	Post-trazodone	P value
LADMax (mm)	13.5 ± 1.0	13.6 ± 1.0	0.798
LASAX (cm)	1.19 ± 0.07	1.25 ± 0.06	0.024*
Ao (cm)	0.93 ± 0.09	0.95 ± 0.08	0.411
LA:Ao	1.28 ± 0.13	1.33 ± 0.12	0.294
LAA emptying (m/s)	0.48 ± 0.09	0.45 ± 0.09	0.297
LAA filling (m/s)	0.47 ± 0.10	0.45 ± 0.07	0.526

Data are mean ± SD

^*Difference between pre- and post-trazodone was statistically significant

LAD_Max = maximum left atrial septal-to-free wall dimension in right parasternal long-axis four-chamber view; LA_SAX = left atrium short-axis diameter in diastole; Ao = aortic short-axis dimension in diastole; LA:Ao = ratio between LA_SAX and Ao; LAA emptying = peak velocity blood flow leaving the left auricular appendage during atrial contraction; LAA filling = peak velocity of blood flow entering the left auricular appendage after atrial contraction
