Reopening of chronic coronary occlusions by low-speed rotational angioplasty.
Total occlusions are found in 10% to 20% of patients undergoing coronary angioplasty. The low-speed rotational angioplasty system (ROTACS) was developed as an addition to conventional guidewire techniques in chronic occlusions. It can be employed if the passage of the obstructed vascular segment with a conventional guidewire fails. The results in 200 patients presented here indicate that angioplasty expands the option of nonsurgical coronary revascularization.
