This table shows the results of the multivariable analyses for rest RVLS and stress RVLS. Multivariable models were stratified for the type of treatment (AVR vs conservative).
Cohort with rest RVLS: *Model #1 was adjusted for age, previous MI, projected AVA and LVEF. †Model #2 was adjusted for age, previous MI, projected AVA and LVLS.
Cohort with stress RVLS. *Model #1 was adjusted for age, projected AVA and LVEF. †Model #2 was Model #1 with further adjustment for rest RVLS.
AVA, aortic valve area; AVR, aortic valve replacement; LVEF, left ventricular ejection fraction; LVLS, left ventricular global longitudinal strain; MI, myocardial infarction; RVLS, right ventricular longitudinal strain.
