Recently, the combination of primary percutaneous coronary intervention (PCI) and adjunctive PercuSurge device support has been reported to be superior to conventional primary PCI in terms of immediate angiographic results. However, there are no data regarding 6-month angiographic results for either the treatment site or the site of the distal protection balloon. The purpose of this study was to address these two issues. Between May and November 2002, a total of 74 patients who had experienced acute myocardial infarction (AMI) underwent either primary PCI (48 patients within 12 hr of AMI) or elective PCI (26 patients with AMI of > 12 hr and < 72 hr) using the PercuSurge device through a transradial approach. The final TIMI 3 flow and myocardial blush grade > or = 2 achieved were 94% and 93%, respectively. Of these patients, three died in the hospital, two died in the third month after discharge, and the remainder of the patients were followed up in our outpatient department for a mean of 13 +/- 2.9 months. Six-month angiographic follow-up was performed in 85.5% (59/69) of patients. The angiographic restenotic rate (defined as > or = 50% restenosis at the target lesion site) was 22.0% (13/59) of patients. However, only 11.9% (7/59) of patients required repeat target vessel revascularization. Moderate obstruction at the site of the distal protection balloon was found in 5.1% (n = 3) of patients during PCI. Six-month angiographic results demonstrated that all three patients had significant stenosis at the site of the distal protection balloon that required PCI. PercuSurge device utilization during PCI in the clinical setting of AMI yielded a substantially higher rate of immediate final TIMI 3 flow in epicardial vessels and increased the integrity of the microvasculature. Combined therapy of PCI with the PercuSurge device appeared to have favorable late angiographic results at the target site. Late significant stenosis occurred at the site of the distal protection balloon if a preexisting moderate or more advanced atherosclerotic lesion was present there.
