| Abstract: | Because a mechanical aortic valve is a contraindication for the implantation of left ventricular assist device, complicated additional procedures such as a replacement with a bioprosthesis and a closure of the left ventricular outflow tract are required to implant the device. Among such procedures, a sandwich plug technique using vascular clips is one of the simple and feasible procedures. However, this technique requires an off-label use of vascular clips within the aorta that could be associated with a risk of dislodgement and embolization. Thus, we developed a modified sandwich technique without using vascular clips, where the valve leaflets were fixed in the closed position using felt patches and sutures instead of vascular clips. This modified technique is a simple and secure method to close the mechanical aortic valve with the minimum use of artificial materials. |
