In this case report the occurrence of a catheter-induced coronary artery dissection is described. In our patient, angiography showed a mushroom-shaped exudate above the left main coronary artery. Intravascular ultrasound revealed a circular dissection with a huge false lumen connected to the true lumen by a small intimal tear. A brief review of the literature on catheter-induced coronary dissection is included. We believe that this case report provides a good illustration of the need for careful reviewing of indications for angiography. Although procedural risks are low, angiography remains an invasive diagnostic test with the potential to cause severe complications. 相似文献

The hemocompatibility and biocompatibility of a stent are determined by the physical and electrochemical properties of the stent surface. The aim of this study was to determine the feasibility, safety and efficacy of implantation of a stent coated with silicon carbide. Baseline characteristics were collected prospectively. The occurrence of cardiac adverse events and the angina score were assessed at clinical follow-up. A total of 193 Tensum stents were implanted in 174 patients. In hospital, one patient experienced stent thrombosis and in 6% of the patients a creatinine kinase elevation to 240 U/l or more occurred. Long-term follow-up was performed in 172 patients, with a mean follow-up of 454 +/- 181 days. Ninety-seven per cent were still alive, 15% had undergone target-vessel revascularization, and 2% had angiographic restenosis and were treated with medication only. Seventy-one per cent of the patients were free of anginal complaints, and 20% had anginal complaints in Canadian Cardiac Society class I or II. The Tensum coronary stent showed to be a safe and efficacious device in this study, with a high primary success rate and favorable long-term clinical followup. 相似文献
