title: [Transcatheter aortic valve implantation: surgeon's view].
abstract: OBJECTIVE
  The technology of catheter- based aortic valve implantation is a new, less invasive therapeutic option for patients with symptomatic high-grade aortic stenosis. The present paper aims to demonstrate that optimal therapy should be provided by a multidisciplinary team consisting of cardiac surgeons, cardiologists and cardioanesthesiologists in a hybrid suite.
  
  
  METHODS
  From June 2007 to April 2009, 234 patients have been treated by transcatheter aortic valve implantation through different access sites (n = 168 femoral artery, n = 56 left ventricular apex, n = 7 subclavian artery, n = 3 ascending aorta) at the German Heart Center Munich, Germany. An algorithm for the choice of the most appropriate access site for the individual patient was established.
  
  
  RESULTS
  The 30-day mortality was 11.2% in this high-risk patient cohort. A certain number of periprocedural complications required surgical management. There was a considerable clinical improvement of the patients 6 months after the procedure.
  
  
  CONCLUSIONS
  Integrating the new methods of aortic valve implantation into a cardiac surgery program, all kinds of surgical and interventional treatment options may be offered to the patient with aortic stenosis by one multidisciplinary team. A qualified and safe performance of transcatheter aortic valve implantation and the management of potential complications require the presence of a hybrid suite.
