Web15 iun. 2024 · The simplified Bernoulli equation was used to calculate LVOT gradient, ignoring the velocity proximal to the LVOT narrowing, as described previously, and the highest instantaneous gradient was reported. In all patients, LVOT gradient was measured in the supine position and during three separate Valsalva maneuvers. The patient was … WebThe most common intracardiac anomaly associated with aortic arch obstruction appeared to be LVOT narrowing downstream to the VSD. This situation occurred in 16 of the 25 hearts with LVOT obstruction. In 10 of these a leftward deviated outlet septum, which presented as a subaortic muscular shelf, obstructed the LVOT downstream to the VSD.
