The essay reported our hospital treated coronary heart disease used percutaneous transluminal coronary angioplasty (PTCA) in 18 cases (men 13, 58. 6±9.2 yrs) and percutaneous transluminal coronary rotational ablation (PTCRA) for 10 cases (men 9, average age 54 yrs) from July 1992 to September 1995. PTCA were performeed in 25 lesions of 23 vessels, resulting in a reduction of diameter stenosis from 81%±12% to 18%±12%. PTCRA were initially successful in 25 lesions of 9 patients and the diameter stenosis were reduced from 86. 2% to 20.2% averagely.
