Chronic coronary artery occlusions remain one of the problems limiting the use of percutaneous transluminal coronary angioplasty (PTCA). We have studied the use of an 0.018 inch laser hot tip wire. It was coupled either to a continuous wave argon or Nd-YAG laser generator and introduced through a balloon catheter to try and cross and dilate a series of chronic coronary artery occlusions in which initial conventional attempts had failed. Four LAD and 6 RCA occlusions were attempted; we successfully crossed and dilated 6 (60%) lesions, 4 (40%) using the laser wire alone to recanalize the occlusion and in 2 a combination of laser wire and conventional means.
