(LV) diastolic filling through the following basic functional elements: 1) reservoir function (collection of pulmonary venous return during ventricular systole); 2) conduit function (passage of blood to the left ventricle during early diastole); and 3) contractile booster pump function (augmentation ...
The left ventricle is located posterior to the right ventricle in the normal heart and is a thick-walled structure that contains relatively fine trabeculation compared with the thin-walled right ventricle, which contains uniformly coarse trabeculation (Fig 8A). These morphologic differences are helpful...
For example, the hybrid procedure has been applied to some children with HLHS who have a borderline left ventricle, which is a ventricle that is smaller than normal but has potential to grow large enough to allow for a two ventricle repair. In some of these children, the hybrid procedure ...
In group I subjects, echocardiographic left ventricular mass (in grams) could be estimated by the general formula: left ventricular mass = 124 (body surface area) + A +/- C, where A is the age-dependent intercept; +/- C encompasses a 95% prediction interval for normal values, which is...
body as it returns to the heart. The right atrium then pumps this blood down into the right ventricle, where it is then pumped to the lungs for re-oxygenation. From the lungs, the oxygenated blood returns to the left atrium of the heart, where it is then pumped to the left ven...

Case 1. Four-chamber view showing asymmetry of ventricular size that could represent either a small right ventricle or a dilated left ventricle.图3病例1。四腔心切面显示心室大小不对称,表现为右心室缩小或左心室增大。 17.Figure 4. Case 2. Four-chamber view showing asymmetry of ventricular size ...
It is more effective than MT alone in reducing ischemia and angina, and when the ischemic burden is large, it may improve long-term survival [3, 5–9]. Given that the perfusion territory of the LM extends up to 84% of the left ventricle, MR is particularly important in significant LM ...
The more severe the stenosis, the closer the ejection click becomes to the first sound, because the rapid rise of pressure in the left ventricle opens the aortic valve soon after the mitral valve has closed. The second heart sound is normal in mild stenosis but in severe stenosis it ...
Vorticity is generated by shear between inflowing blood and the stationary blood already in the ventricle. Vortex formation increases in smaller mitral orifice sizes and dilated ventricles, resulting in a slower vp. Beppu et al. ([27]) showed that in dogs with normal LV function, contrast ...
