The Strecker stent is a balloon-expandable, flexible endoprosthesis constructed of knitted tantalum wire and has been implanted successfully in peripheral arteries. This study presents the first multicenter experience with implantation of this radiopaque device in the coronary arteries in 64 patients of 6591 consecutive percutaneous transluminal coronary balloon angioplasty (PTCA) procedures complicated by abrupt closure. In all except 1 patient the stents (n = 72) were correctly placed, and flow could be reestablished immediately. During hospitalization 12 (19%) patients had stent closures; 5 (8%) patients had Q-wave myocardial infarctions; and 13 (20%) patients underwent bypass surgery (4 on an emergency basis). The in-hospital mortality was 9%: 2 patients died after thrombotic stent occlusions; 2 patients had fatal bleeding complications; and 2 patients died after bypass surgery. Major bleeding complications at the puncture site were observed in 8 (12.5%) patients. Angiograms (n = 45) after 17 +/- 5 weeks revealed a stent patency rate of 89%. Thus the Strecker coronary stent proved to be helpful in the management of acute vessel closure during PTCA. However, in this first series a high incidence of early thrombotic occlusions and bleeding complications warrants close anticoagulation monitoring and limits broader indications.
