Abstract

The catheter combined with endoscope and intravascular ultrasound for laser mitral commissurotomy was develped. The catheter had a lumen for laser fiber and had the function of vending. This newly developed catheter was named the L-PTMC2. The diameter of endoscope was 2.3mm and the diameter of intravascular ultrasound was 2.4mm. Therefore the cutting area of this catheter could be decreased from the old type. With this catheter animal experiment was performed using the mongrel dogs. After the left thoracotomy, the L-PTMC2 was inserted from the left atrium. Scanning with the intravascular ultrasound, the laser-tip was approached to the commissure. Comfirming that the laser tip was touched to the commissure with the endoscope, the laser ablation to was performed. In conclusion, this catheter considered to have an ability in clinical application.
