Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The proposed work seeks to further understand the effects of LAA occlusion on cardiac structure and function, and in homeostasis. Numerous studies have implicated the left atrial appendage (LAA) as the source of the vast majority of left atrial thrombi in the setting of AF3. The University of Pittsburgh Medical Center will be implanting a Left Atrial Appendage filter system (the WATCHMAN® Left Atrial Appendage Filter System, manufactured by Atritech, Inc.). We aim to follow these patients for six months post implant in order to assess their heart rhythm, function, and to do blood tests to evaluate for neurohormonal changes.
