Abstract
A wide variety of surgical approaches for mitral valve repair (MVR) are available. Recent studies have demonstrated that the techniques which “respect rather than resect” the diseased portion of the mitral valve (MV) have comparable clinical outcomes and potentially superior results in terms of physiology (1). Artificial chordal implantation has received increased attention as an MVR strategy during the last few decades, especially when performed through a minimally invasive approach. The Transapical Off-Pump Mitral Valve Repair with Neochord Implantation (TOP-MINI) is a new MVR option that has been approved for patients presenting with severe mitral regurgitation (MR) due to leaflet(s) prolapse or flail (2-4). The procedure is performed using the NeoChord DS1000 system (NeoChord, Inc., Eden Praire, MN) under guidance of direct 2D and 3D transesophageal echocardiography (TEE) (5,6) for both implantation and tension adjustment of the neochordae. The aim of this article is to describe the TOP-MINI procedure in a step-by-step fashion.
