LAA function in patients with atrial flutter is reported to be associated with a regular pattern of LAA emptying and significantly higher peak emptying velocities than in patients with atrial fibrillation, 49 in keeping with the lower incidence of thromboembolism in atrial flutter. 50What is the procedure for a LAA implant?
The implant procedure does not require surgery; however, general anesthesia may be used during the procedure. A catheter sheath is inserted into a vein near the groin and guided across the septum (muscular wall that divides the right and left sides of the heart) to the opening of the LAA.Is oversewing the appendage without amputation safe?
The success and safety of both approaches are incompletely understood. In our own pilot study, the Left Atrial Appendage Occlusion Study (LAAOS), oversewing the appendage without amputation produced successful exclusion in only 45% of patients.When is the LAA used as a decompression chamber?
The physiological properties and anatomical relations of the LAA render it ideally suited to function as a decompression chamber during left ventricular systole and during other periods when left atrial pressure is high.
