Valsalva and exercise echocardiography yield similar LVOT gradients post-PTSMA; hypothesis-generating and should not yet change practice.
Does Valsalva manoeuvre induce similar left ventricular outflow tract gradients compared to exercise echocardiography in patients with hypertrophic cardiomyopathy treated with PTSMA?
Valsalva manoeuvre and exercise echocardiography induce similar degrees of LVOT gradient in HCM patients post-PTSMA, suggesting Valsalva can be the primary stress modality.
Jensen et al. (2010) studied this question.
