Abstract
The feasibility of bivalirudin for anticoagulation during cardiac surgery has been confirmed in four multicenter clinical trials. Here, we report our single-center experience with bivalirudin anticoagulation in “on-pump” and “off-pump” cardiac surgery in a large number of patients with and without heparin antibodies. Data of patients who underwent cardiac surgery with bivalirudin anticoagulation between 06/2003 and 12/2007 at our institution were reviewed. Assessment included procedural success, blood loss, transfusion requirements, re-exploration rates and drug-related complications during the procedures. There were 141 patients treated with bivalirudin, of whom 40 had heparin antibodies. In 26 patients, “off-pump” coronary artery bypass grafting was performed and the remaining 115 patients had surgery with cardiopulmonary bypass (CPB). The procedural success rate after 7 days and after 30 days was 99.4%. The mean blood loss after “off-pump” surgery was 833 ± 310 ml, with a transfusion rate of 30%. The mean blood loss after “on-pump” surgery was 750 ± 494 ml, with a transfusion rate of 56%. Two patients needed re-exploration due to persistent hemorrhage. Overall transfusion rates were increased in patients with heparin antibodies. The current investigation demonstrates that, in experienced hands, bivalirudin anticoagulation can be performed with excellent procedural success and low complication rates during “on-pump” and “off-pump” cardiac surgery. Recent problems associated with the production of heparin have emphasized the urgent need for an alternative for use beyond the limited indication of heparin-induced thrombocytopenia.

Abstract
AIM The aim of this study was to evaluate the safety and efficacy of a new endovascular thoracic stent-graft, which was designed to overcome the restrictions of previously used stent-grafts. METHODS Between May 2004 and March 2008 a prospective evaluation was conducted in 126 consecutive patients (71% men; age 64 [19-86] years). A total of 138 implantations were performed. E-vita stent-grafts were implanted for type-B dissection (N.=56), degenerative aneurysm (N.=25), penetrating aortic ulcer (N.=17), blunt traumatic lesions (N.=10), mobile atheroma (N.=1), suture aneurysms (N.=7) and revisionary surgery following previous endograft implantation (N.=22). All patients eligible for stent-grafting were treated with this system regardless of their clinical status and aortic pathology. The percentage of emergency procedures was 52% (N.=72). Per implantation a mean of 1.3 segments was implanted with an effective total covered length of the aorta of mean 204 mm, median 230 mm (0-450 mm). In 32 of 39 cases with more than one segment, the entire descending aorta was included in the procedure. RESULTS The 30-day mortality rate was 12.3% (17 patients). All deaths but one were in the group of emergency surgery patients. This results in mortality of 1.5% in the elective and 22% in the emergency procedures. Reversible procedure-induced spinal cord ischemia was observed in 2 cases. Stroke occurred in 2.8% (4 patients). Primary technical success was rated at 77 % (106 procedures) and secondary success at 89 % (124 procedures). CONCLUSION All forms of thoracic aortic disease can be treated with this new stent-graft. It has proved particularly valuable in cases of difficult conditions in the aortic arch and extended aneurysms. In particular, it is possible to cover the entire thoracic aorta with two or three stent-graft segments, thus considerably reducing the number of connections.
