The mitral valve is positioned between the heart’s left atrium and ventricle. It opens to allow blood to flow into the left ventricle and closes to prevent backflow into the left atrium.

The left-hand side pumps oxygenated blood around the body. Each side of the heart consists of an atrium and a ventricle which are two connected chambers. The atria (plural of atrium) are where the ...

The oxygenated blood flows back to the heart via the left atrium, where it's directed to the left ventricle. From there, it is pumped to the body. The electrical system of the heart is a complex ...

Diastolic dysfunction occurs when the left ventricular myocardium ... fashion from the left atrium. This can be a normal physiologic change with aging of the heart or result in elevated left ...

The second heart sound (S2) is produced by the closure ... proportion of the left ventricular stroke volume entering the left atrium, causing the left ventricular pressure to decrease faster.

Atrial functional mitral regurgitation (AFMR) is a common type of MR linked to high rates of heart failure, highlighting the ...

Inter-atrial shunt device therapy has shown mixed results in clinical trials, with clinical 'non-responders' typically showing features of more advanced heart failure. We aimed to analyse the ...

CT scan-assessed high right ventricle-left ventricle ratio of the heart predicts major adverse cardiovascular events in PH ...
