Background: Several different stent types are available for intracoronary placement. Thus far, no clinical trial has demonstrated the superiority of either stent design over the other, although ongoing studies are still investigating this problem. Preliminary study results report a favourable outcome after implantation of Sirius CarbostentTM (Sorin Biomedica, Italy). Methods: In this study we analyzed the rate of postinterventional adverse cardiac events and the clinical and angiographic outcome after placement of 120 Sirius CarbostentsTM in 105 consecutive unselected patients (60.7+11.7 years, 79.8% male) between 2000 and 2002. Routine control angiography was not planned, but was scheduled in symptomatic patients or an unclear morphologic or functional situation. Results: A total of 120 Sirius CarbostentsTM were implanted, in 20 patients additional 29 stents of other types. Indications for intervention were stable angina (57.1%) and acute coronary syndrome (42.9%) including ST-elevation infarction (22.9%). Multivessel disease was present in 71.2%. 50.4% of stenoses were classified as type C, complex stenoses were found in 51.4%, calcified lesions in 54.3%. In 30.5% a recanalization of occluded vessels were necessary. Angiographic success was 100%. As adverse events were documented: non-Q-wave-infarction (3.8%),and target vessel intervention (2.9%). Stent thrombosis did not occur. Clinical and angiographic assessment (39/105 patients) after six months showed a restenosis of 41%, target lesions intervention in 28.2%, angioplasty of a different lesion in 25.6%. Restenosis in those patients where only Sirius CarbostentsTM were implanted was 37.5%. Conclusions: Primary success rate and periinterventional complications after placement of Sirius CarbostentsTM show excellent results in this unselected, complex patient population. A relatively high number of restenoses occur due to the complexity of coronary lesions. Those patients treated only with Sirius CarbostentsTM the restenosis rate was lower in comparison to combined stents. |
