- W2046648951 abstract "The purpose of this study was to determine the results of the first Wiktor stent implantations in bailout conditions. From December 1990 to July 1991, in a total of 10 centers, 69 patients presenting with threatened or total closure after balloon angioplasty each received the Wiktor stent in 1 coronary artery. In these 69 coronary arteries, a total of 72 stent deliveries were attempted and 69 were successful (delivery success rate 95%). Delivery failure was treated conservatively in 2 patients and surgically in 1 patient. Emergency surgery was also performed in 2 patients, who after successful stent delivery showed progressive distal extension of the dissection. In addition, 5 patients underwent elective surgery to avoid the possibility of stent thrombosis because the myocardial area at risk was considered too large. Postprocedural blood transfusion was performed in 6% of the patients, whereas stent thrombosis occurred in 10 of 59 patients (17%), resulting in 2 deaths. Finally, 65% of the patients had a successful stent implantation without major periprocedural complications. At 6-month follow-up, only 9% of the patients experienced recurrent angina, whereas a > 50% arterial diameter narrowing was observed in 27% of the patients. Thus, the radiopaque Wiktor stent can be accurately and conveniently implanted in dissected coronary arterial segments. However, as for similar bailout devices, the number of thrombotic and bleeding events remains high." @default.
