Diastolic dysfunction occurs when the left ventricular myocardium is non-compliant and not able to accept blood return in a normal fashion from the left atrium. This can be a normal physiologic ...

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 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 ...

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 ...
