Provocable LV outflow gradients occur across LVH etiologies; hypothesis-generating for nonspecific flow, not yet guiding management.
Does provocation with Valsalva maneuver and nitroglycerine induce LV outflow acceleration in patients with LV hypertrophy?
Dynamic, intracavity LV gradients are a nonspecific flow abnormality frequently found in LVH patients upon provocation, independent of etiology.
Faber et al. (1998) studied this question.
