We have introduced a personal computer and developed software in order to improve safety of high-speed atherectomy and perform effective treatment with it. The system is configured so that it can detect the rotation signal from the record output terminal of RC 500 Rotablator Console (Boston Scientific Corporation, a treatment device), and display charts on a screen of a personal computer. Principal function is to notify a doctor in attendance with two different audible alarms if the rotational speed drops by 5,000 rpm or more and 10,000 rpm or more from the maximum rotational speed respectively. In addition to that, ablation time, maximum rotational speed, maximum rotational drop speed, maximum rotational speed reduced by the ablating rotational speed in progress (integral) are displayed for each ablation. By the clinical application of this software, it became easier to understand the position and the hardness of the arterial sclerosis in the coronary artery and the software has contributed to the increase of safety in ablation technique and effective treatment.
