In patients with atrial fibrillation, closure of the left atrial appendage (LAA) is recommended to prevent thromboembolic events, however, conventional exclusion or excision techniques have potential drawbacks such as persistent blood flow into the appendage and a residual stump. We propose a simple and easy technique for LAA closure consisting of intra-atrial excision of the LAA, which is invaginated into the left atrium (LA), and direct suture closure of the orifice from inside the LA.
