Does the use of a coronary autoperfusion catheter reduce the need for emergency surgical revascularization in patients with complicated coronary angioplasty?
The use of a coronary autoperfusion catheter during complicated angioplasty may decrease the need for emergency surgical revascularization.
May reduce emergency surgery need in complicated angioplasty; hypothesis-generating, requires randomized confirmation.
Between February and July of 1989, 22 patients underwent the use of the Stack autoperfusion catheter following acute occlusion or obstructive dissection during coronary angioplasty; in 20 cases conventional balloon was used in an attempt to correct the angiographic appearance followed by the use of Stack catheter when results were sub-optimal. Only 1 patient (4.5%) required surgical revascularization. Although our study is not prospective or randomized, our observations suggest a significant impact in decreasing the need for emergency surgical revascularization after complicated coronary angioplasty with the use of this approach.
