An estimated 47% of thrombi in valvular atrial fibrillation (AF) and 91% of thrombi in nonvalvular AF are localized in the left atrial appendage (LAA) LAA flow stasis (or spontaneous echocardiographic ...

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 atrial ...

To heart wire, Krishnan said: "We are describing this novel cardiac anatomy for the first time. Increased recognition of this left atrial septal pouch has the potential to cause a paradigm shift in ...

An award-winning presentation during the 2023 ARRS Annual Meeting suggests that correctly occluded left atrial appendages could present maximal reduction in left atrial flow stasis and thrombogenicity ...

Ronald Wharton, MD: Hello. This is Ronald Wharton. I am a cardiologist at Montefiore Medical Center at the Albert Einstein College of Medicine in Bronx, New York, and I just thought I would share with ...

Providing validation to what many physicians are already doing, a new study suggests that non-vitamin K antagonist oral anticoagulants (NOACs)—rivaroxaban, in particular—are effective alternatives to ...

THE preoperative clinical diagnosis of left atrial thrombi is difficult. A history of systemic embolization does not necessarily indicate the presence of an atrial thrombus. A reliable method of ...

Surgical occlusion of the left atrial appendage has been hypothesized to prevent ischemic stroke in patients with atrial fibrillation, but this has not been proved. The procedure can be performed ...

The mitral valve, so named because of its similarity to a bishop’s miter, has five important structural elements: 1) the mitral annulus, 2) the mitral valve leaflets, 3) the commissures, 4) chordae ...
