Impact of Implantation of an LAA Occluder on ANP and BNP Level and Quality of Life

Impact of Implantation of an LAA Occluder on ANP and BNP Level and Quality of Life

Closure of the LAA by several devices is a alternative therapy to oral anticoagulation in patients with Atrail fibrillation. Nothing is known about the acute influence of a device closure of the LAA on the secretion of ANB nad BNP hormones. Therefore aim of our study is to measure ANB and BNP levvels before and after Implantation of an LAA closure device.

ANB and BNP levels are measured before, directly after and late after 24 h in central or periphereal venous blood from patients undergoing interventional LAA closure.

Inclusion Criteria:

• patients undergoing LAA closure

Exclusion Criteria:

• none
