Coronary angiography gives a visual impression about the severity of the stenosis. But it need not imply the actual functional significance of the stenosis in terms of flow physiology. A downside of the study was that it had included lesions of 50 to 79% stenosis also. identified physiologically significant stenosis.

SCAPE is an acronym for sympathetic crash acute pulmonary edema, which can typcially occur in Pickering syndrome with renal artery stenosis [1]. Another term for transient acute pulmonary edema which occurs in renal artery stenosis is flash pulmonary edema.

Graft material has the disadvantage that it will not grow as the baby grows and can lead to supravalvar pulmonary stenosis later, one of the delayed complications of arterial switch. This is diagrammatic representation of stenosis of pulmonary artery at the site where it has been repaired.

Transcatheter aortic valve replacement (TAVR) is increasing in popularity for symptomatic severe aortic stenosis. No calcifications in the artery causing vascular stenosis. Contralateral or left atherosclerosis in the carotid artery with significant stenosis or occlusion was a contraindication for this approach.

In the geometry, the size of the plaque, its relationship to luminal stenosis, arterial remodeling and eccentricity can be evaluated. Transient ischemia may occur while negotiating tight stenosis or small vessels. Plaque morphology assessment with IVUS Plaque morphology can be assessed in terms of its geometry and echogenicity.

Colour Doppler echocardiography is very useful in giving a quick visual assessment of regurgitation and stenosis of heart valves. Stenosis of the valves can be made out by the reduced opening at the time when it is supposed to be open. All high velocity flows across the diseased valves will be shown as mosaic jets.

Bicuspid leaflets are likely to have both stenosis and regurgitation and both can progress as age advances, so that they may present with aortic stenosis most often in the older age group. And then, this is likely to be regurgitant also.

So that is why we see straightening of left border, typically heard of in mitral stenosis with left atrial enlargement and mild pulmonary hypertension. Normally, the main pulmonary artery segment will be concave and left atrial appendage region also will be not prominent.

Fetal aortic valvuloplasty is considered for fetuses with severe valvar aortic stenosis and echocardiographic features suggesting a risk of progression to hypoplastic left heart syndrome. Though surgical options are available for infants with hypoplastic left heart syndrome, morbidity and mortality are high.

SMART 4 ( NCT04722250 ) studied patients with severe aortic stenosis and a small aortic annulus who underwent transcatheter aortic valve replacement (TAVR). The study concluded that among low-risk patients with severe aortic stenosis, TAVI is as effective as SAVR in terms of the composite outcome of death or stroke at 1 year.

When there is associated mitral stenosis, the colour Doppler jet of mitral flow merges with that of aortic regurgitation in the left ventricle as both occur in diastole. m/sec, indicating the absence of any associated aortic stenosis. This is because the regurgitant flow into the left ventricle is towards the transducer in this view.

Here is an example of a continuous wave Doppler interrogation of aortic stenosis and regurgitation. Most of the abnormal jets across abnormal valves and those across a ventricular septal defect and patent ductus arteriosus need either continuous wave or high pulse repetition Doppler for analysis due to the high velocity.

So it will not produce a true LV to aorta pullback tracing, which is required in cases like aortic stenosis. When the tip is in the left ventricle, this region will be in the aorta sometimes. For that you will have to use a catheter without side holes like this, like a multi-purpose catheter or some other catheter you have to use.

If a nominal right atrial pressure of 10 mm Hg is added to it, right ventricular pressure and indirectly the pulmonary artery systolic pressure are obtained, in the absence of pulmonary stenosis. If there is high right atrial pressure with elevated jugular venous pressure, 15 or 20 mm Hg may have to be added instead of 10 mm Hg.
