The left atrium is one of the four chambers of the heart, located on the left posterior side. Its primary roles are to act as a holding chamber for blood returning from the lungs and to act as a pump ...

For patients with atrial fibrillation, the use of oral anticoagulant therapy to prevent stroke is limited by the risk of bleeding. Left atrial appendage closure is considered for patients who are ...

As one of the most common arrhythmias, atrial fibrillation (AF) is prone to cause ventricular rhythm irregularity, impaired heart function and atrial mural thrombosis. The combined operation of ...
