Methods:
We performed a retrospective review of 66 patients who had an
echocardiogram prior to ibrutinib treatment. LA strain was measured with
TOMTEC Imaging Systems, obtaining peak atrial longitudinal strain (PALS)
and peak atrial contraction strain (PACS) on 4-chamber and 2-chamber
views. Statistical analysis was performed with Chi-square analysis,
T-test, or binomial regression analysis, with a p-value < 0.05
considered statistically significant.
