Abstract:
Mitralign, Inc. (Tewksbury, MA) has developed a proprietary mitral valve repair system that attempts to mimic surgical suture annuloplasty. The Mitralign system is a set of devices approaching the posterior mitral annulus through the left ventricle. A steerable catheter is delivered via a 12.5Fr deflectable guide catheter between the papillary muscles facing the posterior annulus. The steerable catheter and a two-arm (Bident) catheter help place two pairs of wires through the annulus at the P1 and P3 locations. Each crossing wire is passed into the left atrium under transoesophageal (TEE) guidance. Once the wire pair is placed at one location, surgical pledgets are delivered over the wires and anchored across the annulus. The pledgets are pulled together to decrease the annulus circumference and the achieved plication is locked in place. Once the entire procedure is completed at one location, the next wire pair is placed at the other scallop location. TEE is an enabling imaging modality for the Mitralign procedure, which is performed with close collaboration between interventional cardiologists and echocardiologists.
