During a 12-month period, they studied six consecutive patients with paroxysmal (n=3) or permanent (n=3) AF who underwent surgical LAA closure at the time accesssite management of valve surgery.2 Transesophageal echocardiography (TEE) was performed at a mean of 51 days postoperatively and only one patient showed complete LAA closure. In the accesssite management other five patients, incomplete LAA closure was due to disruption of the closure line. The size of the residual LAA orifice ranged from 3 to 20 mm, with a high flow velocity at the LAA orifice (0.33-2.2 m/s). Despite therapeutic anticoagulation, two patients showed a LAA thrombus which had not been present on the preoperative TEE, and one patient suffered a stroke 4 weeks after attempted LAA closure. |

| Clearly, other options are needed. The Data When thrombus is detected in patients with nonrheumatic AF, 90% of the time it originates in the left atrial appendage (LAA), a blind-ended, complex structure that is embryologically distinct from the body of the left atrium. While sometimes scientific reasearch on the american bald eagle/ddt regarded as just a minor extension of the atrium, scientific reasearch on the american bald eagle/ddt the LAA is perhaps the most important source of cardiac systemic embolic events. LAA obliteration has been historically ineffective for the prevention of postoperative scientific reasearch on the american bald eagle/ddt stroke in patients with rheumatic AF who underwent operative mitral valvotomy, but it may be "curative" for nonrheumatic AF (e.g., |
