can increase both pressure and volume in the left atrium, causing it to enlarge. Another possible cause of LAE is aortic stenosis. This is the narrowing of the aortic valve, which can lead to ...

this time in the left atrium. The semilunar valves stop the back flow of blood into the heart. There is a semilunar valve where the aorta leaves the left ventricle and another where the pulmonary ...

showing the aneurysm to be behind the aorta but anterior to the left atrium. The small communication between aneurysm and atrial appendage is evident. C presents the relation of the aneurysm to ...

The number one cause of death in Korea is still malignant neoplasms (cancer), followed by cerebrovascular disease and heart ...

Mild poststenotic dilatation and increased left atrium/aortic root transverse ratio is noted. Blood flow velocity in the left ventricular outflow tract (LVOT) of the same patient (Figure 3 ...

The ECG in patients with aortic regurgitation is non-specific and may show LVH and left atrial enlargement. In acute aortic regurgitation, sinus tachycardia due to the increased sympathetic ...

The ECG in patients with aortic stenosis frequently shows left ventricular hypertrophy with strain and left atrial enlargement; however, these findings are non-specific for aortic stenosis.

In normal subjects, the left atrial "kick" contributes in the range of 20% to the stroke volume. Since this percentage increases substantially in aortic stenosis, the loss of the atrial kick with ...

It likewise opens due to a build-up of pressure, this time in the left atrium. The semilunar valves stop the back flow of blood into the heart. There is a semilunar valve where the aorta leaves ...

Aortic stenosis is a condition that occurs when the opening of the aortic valve becomes narrowed. The aortic valve is a heart ...
