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. In this technique, complete elimination of the LAA was achieved without leaving a residual stump because the LAA was excised at the orifice and was closed at the base of the LAA.
