The tricuspid valve controls blood flow between the right atrium and right ventricle. The bicuspid or mitral valve does the same on the left. The heart consists of four chambers.

The primary function of the mitral valve is to allow the normal flow of blood from the left atrium to the left ventricle and to stop blood from going in the wrong direction.

Structural or functional abnormalities within the heart's left atrium, with or without symptoms, may increase a person's risk of developing dementia later in life by 35%, according to new research ...

Echo analysis of the left atrium and mitral annulus also showed that use of the MitraClip was associated with significant positive remodeling. In a multivariable analysis, postprocedural MR grade ≥ 2+ ...

A novel transcatheter-implanted system that shunts blood flow from the left to right atrium through the coronary sinus has shown an incremental clinical benefit from the 1-year to 2-year follow-up.

Johansen says the team looked at three markers that could be obtained from routine medical tests to measure the function of the left atrium. These include an echocardiogram (a test of the heart ...

We describe two siblings with a homozygous loss-of-function variant in CORIN. Both presented with cardiomyopathy, hypertension, fibrosis, and arrhythmia isolated to the left atrium.

Atrial cardiopathy, characterized by abnormal size and function of the left atrium, has been associated with an increased risk of stroke and atrial fibrillation (AF), and because both stroke and ...
