Dynamic lvot obstruction on echo
WebThe Valsalva hemodynamic effect consists of four basic phases which can be used in echocardiography to yield an accurate diagnosis. Valsalva is used to decrease preload and provoke left ventricular outflow tract (LVOT) gradient in dynamic LVOT obstruction. In addition, a decrease in E/A ratio in mitral inflow >50 % with Valsalva correlates with ... WebConclusion: Spontaneous or dobutamine-induced dynamic LV obstruction is documented in 32% of patients with LVBS, is correlated with the presence of septal hypertrophy and may play a role in the development of LVBS in this subset of patients. In those without se ptal hypertrophy a dynamic obstruction is rarely induced with dobutamine and
