What is stenosis after gastric bypass surgery? After gastric bypass surgery for weight loss, the new connection between the stomach pouch and the small intestine may narrow. This is called an ...

Intracranial trans-stenosis gradients showed significant variability with head position. Additionally, LP OP measurements increased by an average of 44.3% with head rotation. Dynamic IJV stenosis was ...

Compared with patients with high-gradient aortic stenosis, patients with low-gradient aortic stenosis and reduced LVEF have worse clinical outcomes. Clinical outcomes are worse in patients with ...

However, in both elderly and younger patients with aortic stenosis, the triad of low gradient, low output, and low ejection fraction indicates a poor prognosis. In some there is severe LV ...

Significant tricuspid regurgitation (TR ... effective transcatheter device performance (in terms of TR reduction and absence of TV stenosis); no device‐related obstruction of forward flow or pulmonary ...

mitral regurgitation (MR), and tricuspid regurgitation (TR). The assessment of valvular stenosis and regurgitation was carried out as recommended by the American Society of Echocardiography. 12 ...

Aortic stenosis (AS) was historically considered a disease of the ... pulmonary hypertension; TR, tricuspid regurgitation; TV, tricuspid valve. Figure 3. Changes in right ventricular function with ...

Results Eighty-nine patients were included in the study. Most commonly, ipsilateral rotation resulted in ipsilateral IJV stenosis and gradient development at C4–6 and contralateral stenosis and ...

In Revista Española de Cardiología, González-Cánovas et al.1 reported the results of a study that examined whether severe aortic stenosis (AS) with low-gradient ...

On the other hand, if increased output increases gradient and valve area increases only slightly, the implication is that there is severe fixed aortic stenosis, a condition that has probably ...
