Kidney insufficiency as postinterventional complication of TAVI

With the introduction of transcatheter-based aortic valve implantation (TAVI) the interventional approach gained great importance in the treatment of aortic stenosis. After this technique began with indications for high risk patients only, intermediate risk patients are today also amenable for TAVI as long as the transfemoral approach is chosen. Numerous predictors have been identified that would lead to periprocedural complications and are defined by patient comorbidities as well as being inherent to the technical approach. Although vascular complications and postinterventional paravalvular regurgitation have been minimized over the past few years by novel technologies, there is a prevailing individual risk on the side of the patient brought about by the specific pathophysiology of the cardiorenal syndrome. The corresponding data situation is explained. © 2018, Springer Medizin Verlag GmbH, ein Teil von Springer Nature.
