There is a one-way valve that allows blood to enter the aorta from the left ventricle during the contraction of the ventricle (systole) but prevents blood from flowing backward into the heart when the ...

Grade II lesions show retrograde flow during systole and antegrade flow during diastole. Grade III lesions have flow that is completely retrograde, regardless of cardiac contractility (Figures 1 & 2).

Guarding the inlet to the left ventricle, the mitral valve prevents backflow to the left atrium during ventricular systole. In its open state, the valvar leaflets are like a funnel extending from the ...

The Simplici-T ® Annuloplasty System offers a first-of-its-kind approach to mitral and tricuspid valve repair. It is the first flexible band to eliminate the need for traditional sizing ...

THE detection of a continuous murmur with systolic accentuation is of the highest significance in the diagnosis and in the location of the site of an arteriovenous fistula. It is therefore ...

And so, the filling occurs with higher pressure, reducing the amount of blood available to pump throughout the body during the systole phase. It causes a backup of fluid into the lungs and the body.

During diastole, the balloon was inflated and arterial blood, aspirated via the arterial catheter, was actively infused into the coronary sinus. During systole, the infusion stopped and the balloon ...
