Angioplasty in the stent era: results of a consecutive series of patients undergoing coronary angioplasty without surgical backup.

UNLABELLED: We prospectively studied the angiographic and clinical outcome in a group of 117 consecutive patients (140 vessels) undergoing coronary angioplasty in the stent ERA without surgical backup. There were no exclusion criteria. Intracoronary stents were deployed in 36 vessels (26%) either as a bailout procedure or for a suboptimal result following balloon angioplasty. Procedural success was achieved in 126 vessels in 108 patients (90%). Two patients developed Q-wave myocardial infarction and another two developed nonQ myocardial infarction. One patient died suddenly 2 days following an initially successful procedure. No patient was referred for emergency coronary artery bypass grafting and there were no vascular complications. Clinical or angiographic follow up was available in 87% of the patients and an angiographic follow up in 50% of the patients. At a median angiographic follow up of 210 days restenosis was seen in 34% of the vessels. Restenosis occurred in three of the 21 (14%) stented vessels and in 18 of the 41 (44%) nonstented vessels (P<0.02).
CONCLUSION: In the stent era, coronary angioplasty can be safely performed without surgical backup. A satisfactory immediate and long-term result could be achieved by stenting 26% of the vessels.
