The V-Wave device. A) & B). Sagittal and axial views of the V-Wave device. The device consists of an hourglass-shaped nitinol frame with ePTFE encapsulation and three porcine pericardial leaflets sutured together with a prolene suture. The lumen size of the device is 5 mm at the level of the fossa. C) & D). Angiographic (left) and echocardiographic (right) images showing the deployment of the left side of the V-Wave device. E) & F). The V-Wave device located at the interatrial septum as seen by angiography (left) and computed tomography (right). G) & H). Transoesophageal echocardiography images of the V-Wave device immediately post implantation (G) and at one-month follow-up (H) showing adequate positioning and function.

After opening the left side in the mid portion of the LA (Figure 1C, Figure 1D), the system was pulled back up into the interatrial septum, where the device was detached and finally released by pulling back the delivery catheter (Figure 1E, Figure 1F, Moving image 1). TEE immediately after device implantation (Figure 1G), and the Qp/Qs was calculated at 1.17:1. The patient was discharged 24 hours after the intervention with no complications. TEE confirmed the correct position of the device, the patency of the interatrial shunt, and the absence of thrombus (Figure 1H).
