ABSTRACT
Objective To evaluate the treatment of in-stent restenosis with rotational atherectomy and balloon angioplasty. Methods The rotational atherectomy and 4～6 atm low pressure balloon angioplasty was performed in 3 patients with in-stent restenosis and follow up after treatment. Results All cases were succeeded. The bradycardia occurred in one patient was quickly disappeared without treatment, two other patients were found no effect on heart rate, hemodynamic performance, global LV function, or regional wall motion. No complications, angina, death or other coronary event occurred during the follow up for 6～12 months. Two of them was performed coronary angiography after 6 months and showed the diameter of target vessel was less than 30% as compared with that on coronary angiography which performed immedately after operation. Conclusion The management of in-stent restenosis in target vessels using a combination of rotational atherectomy and balloon angioplasty is safe and efficient.
