Abstract
The 0.014 inch magnum Meier wire was used as the primary tool for recanalization of chronic total coronary artery occlusions in 230 consecutive patients treated by a single operator over a 3-year period. Exclusive use of the magnum wire resulted in an acute success rate of 80.9% in all occlusions and 64.7% in occlusions with a duration of > 6 months. The complication rate of this procedure was extremely low with only one nontransmural myocardial infarction occurring. There were no vessel perforations, no in-hospital deaths, and no need for acute surgery. After failure to recanalize with the magnum wire, various other devices (conventional stiff guidewires, jagwire, crosswire) were used resulting in only six additional successful recanalizations but also in two vessel perforations with spontaneous closure of the perforation hole. Therefore, the 0.014-inch magnum Meier recanalization wire is highly effective for recanalization of chronic coronary artery occlusions, if used as the primary tool by an experienced operator, and is associated with an extremly low complication rate.
