The loop technique is commonly adopted as a surgical procedure in mitral valve repair to secure the effective valve area of the valve leaflet, and to preserve, as much as possible, the physiological movement of the valve leaflet or annulus. On the other hand, the prolapsed valve leaflet is very high in some patients. In this case, the redundant valve leaflet may increase the risk of development of postoperative systolic anterior motion because the valve leaflet is not surgically removed at all. In this article, we describe a simple procedure for preventing systolic anterior motion after mitral valve repair using the loop technique.
