Transcript of the video: Hemodynamic vise is the term given to compression of a vertical vein, which ascends to the brachiocephalic vein, between a bronchus and pulmonary artery. This is the typical location of the hemodynamic vise, between the pulmonary artery and left bronchus. Hence it is known as hemodynamic vise.

The striking finding is the huge enlargement of the right pulmonary artery, almost aneurysmal dilatation of right pulmonary artery. Main pulmonary artery is also grossly dilated. And you can see left pulmonary artery shadow and rest of it is not seen here. So massive enlargement of pulmonary arteries.

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. Sympathetic crashing acute pulmonary edem a. Prog Cardiovasc Dis.

As the aorta is small in hypoplastic left heart syndrome, proximal portion of the pulmonary artery is taken and along with the valve, it is used to reconstruct the proximal aorta, this region, and it is connected to the right ventricle. So right ventricle maintains both systemic and pulmonary circulation after a Norwood procedure.

One is ventricular septal defect, second is overriding aorta, third is pulmonary stenosis, usually right ventricular outflow tract stenosis and associated right ventricular hypertrophy. Pulmonary stenosis, which is usually right ventricular outflow tract stenosis. This will almost invariably result in severe pulmonary regurgitation.

That is, right ventricle is connecting to aorta, and left ventricle to pulmonary artery. That is, pulmonary artery is transposed over to the right ventricle, and aorta over to the left ventricle, so that normal anatomy is restored. In dextro transposition of great arteries or D-TGA, there is ventriculoarterial discordance.

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

This is the schematic diagram of the heart in which you can see right atrium, right ventricle, left atrium, left ventricle, aorta and pulmonary artery. Similarly, another right sided valve is the pulmonary valve. There could also be some mild leak in the pulmonary valve, both these, in normal persons.

Inspiratory fall in intrathoracic pressure is transmitted to the pulmonary veins, but not to the pericardial cavity. Relative change is more on the right sided chambers.

Sudden breathlessness at night in those with known heart disease is usually due to collection of fluid in the lungs (pulmonary edema). During day time, when one is walking about, any extra fluid in the body tends to collect in the legs, due to the effect of gravity.

Leaving a fenestration in the interatrial septum during a Fontan repair is useful in relieving the central venous congestion when pulmonary blood flow is driven by venous pressure in Fontan repair. They noted that benefit was more pronounced if mean pulmonary arterial pressure was 13 mm Hg or more, as expected.

While standard pigtail catheter is mainly used on the left side, Grollman PA is a catheter used for pulmonary angiography, on the right side. It is used for pulmonary angiography by the transfemoral route and it is also used for clot lysis in pulmonary embolism. So it is used both diagnostically as well as therapeutically.

Pulmonary embolism is obstruction of blood vessels of the lungs by clots carried by blood circulation, usually from the legs. Remember that by preventing blood clots in the legs, you are preventing a life threatening disease called pulmonary embolism, in which oxygen level of blood can fall markedly.

Right atrial hypertrophy as in tricuspid stenosis, pulmonary stenosis and pulmonary hypertension. But in a VSD with pulmonary hypertension A wave is not prominent. We noted that prominent V waves or CV waves can occur in tricupsid regurgitation. A prominent A wave can occur when the atrium is hypertrophied.

Systole is identified here by the pulmonary arterial colour flow mapping. This is parasternal short axis view, In normal valve, you can hardly see the leaflets because they are open and almost approximate to the aortic wall. So you will hardly able to see in real systole. This is the corresponding echocardiogram in bicuspid aortic valve.

The cyanosis in Ebstein’s anomaly, is usually not due to pulmonary hypertension, but because tricuspid regurgitation jet is directed across the atrial septal defect. Ebstein’s anomaly may be associated with atrial septal defect or a patent foramen ovale, in about 50% of cases.

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. The early diastolic pulmonary regurgitation (PR) gradient (peak PR gradient) will give an estimate of mean pulmonary artery pressure.

I has to be done quite early in life before the left ventricular muscle mass regressed due to the lower load of the pulmonary circulation.
