LVOT PG decreased from 90 ± 20 mmHg at initial TTE to 33 ± 35 mmHg at follow-up TTE. In addition to the use of negative inotropic agents, it may be important to improve some other …

May 5, 2022 · Left ventricular outflow tract obstruction (LVOTO) is commonly associated with systolic anterior motion (SAM) of the mitral valve. Congenital heart disease is an important …

Dec 23, 2022 · Left ventricular outflow tract obstruction (LVOTO) limits blood flow from the left ventricle. The level of obstruction can be valvular, sub-valvular, or supravalvular. It can include …

Nov 15, 2021 · LVOTO is caused by fast-flowing blood through the LV outflow tract which pulls the mitral valve anteriorly (towards the LV outflow tract) due to a Venturi effect. This is known …

However, the changes of the LVOT pressure gradient (LVOT PG) in LVOTO with various conditions remain unclear. Methods: The clinical characteristics and echocardiographic …

Apr 13, 2022 · Apical five-chamber view showing trace MR and minimal turbulence in the LVOT. LVOT = left ventricular outflow tract; MR = mitral regurgitation.

To evaluate if left ventricular outflow tract /aortic valve (LVOT/AO) diameter ratio measured by cardiac magnetic resonance (CMR) imaging is an accurate marker for LVOT obstruction in …

Sep 18, 2017 · Left ventricular outflow tract obstruction (LVOTO) occurs from not only obstructive hypertrophic cardiomyopathy but also other conditions such as sigmoid septum or post mitral …

Color Doppler imaging showed accelerated flow with a pressure gradient (PG) of 56 mmHg at the left ventricular outflow tract (LVOT). Cardiac magnetic resonance imaging revealed mild …

In patients with obstruction of the left ventricular outflow tract (LVOT), the Doppler echocardiography-derived pressure gradient (PG) is currently the accepted approach (1, 2); …
