The Bonhoeffer MULTI-TRACK™ System

The NuMED MULTI-TRACK™ Kit is a well established innovative system for Mitral Dilatation.


This operator friendly system has the advantages of double balloon techniques while using a simple, single guidewire approach.  The procedure times easily match those of single balloon techniques while achieving consistently higher valve areas post dilatation.  The mismatch of the round shape of a single balloon with the oval mitral orifice probably explains the better results with double balloon dilatation. (Figures A 30mm balloon & B 2 18mm balloons)

With the guidewire still in place a MULTI-TRACK™ angiographic catheter is advanced into the left atrium for the measurement of the transmitral gradient after the dilatation.  If the result is satisfactory all catheters can then be removed, otherwise balloons of different sizes could still be advanced over the wire.

The MULTI-TRACK™ system allows to measure the transmitral gradient  even through a single venous approach. This is obtained by gliding  two  MULTI-TRACK™ angiographic catheters along the wire which is positioned in the mitral orifice.  Therefore the arterial approach routinely used for mitral dilatation can be avoided.
