Key result
Cardiopulmonary exercise testing was feasible in 130 of 131 patients (99.2%) with asymptomatic or equivocal aortic stenosis, with high reproducibility and no cardiovascular deaths at 1 year.

Is cardiopulmonary exercise testing feasible, reproducible, and safe for assessing exercise physiology and guiding treatment in patients with asymptomatic or equivocal symptomatic aortic stenosis?
Cardiopulmonary exercise testing is a feasible, reproducible, and safe tool for evaluating hemodynamic compromise and guiding valve replacement decisions in patients with asymptomatic or equivocal symptomatic aortic stenosis.
Le et al. (2015) conducted an observational in Asymptomatic or equivocal symptomatic aortic stenosis (n=131). Cardiopulmonary exercise testing (CPX) was evaluated on Feasibility of CPX. Cardiopulmonary exercise testing was feasible in 130 of 131 patients (99.2%) with asymptomatic or equivocal aortic stenosis, with high reproducibility and no cardiovascular deaths at 1 year.
