When left atrial enlargement occurs, it takes longer for cardiac action potentials to travel through the atrial myocardium; thus, the P wave also lengthens. Therefore, the criteria for diagnosing ...

The left atrial appendage is the most common site for cardiac thrombus. It is anatomically attached to the left inferior portion of the left atrium and consists of muscular trabeculae. The left ...

The newly oxygen-rich blood (shown in red) returns to the heart and enters the left atrium. Blood flows through the left atrium into the left ventricle. The left ventricle pumps the oxygen-rich ...

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 ...

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

CHICAGO -- For patients at high risk of stroke who underwent catheter-based atrial fibrillation ablation, left atrial appendage closure led to less bleeding compared with oral anticoagulation ...

Atrial functional mitral regurgitation (AFMR) is a common type of MR linked to high rates of heart failure, highlighting the need to understand its prognostic factors. Tricuspid regurgitation (TR) is ...

With no differences between single or dual antiplatelet therapy or anticoagulants at 6 months, an RCT is warranted for ...
