Feasibility of a Fast Track Concept for Patients Undergoing Transfemoral Transcatheter Aortic Valve Implantation Based on Individualized Low-dose Analgosedation and Preprocedural Fluid Optimization Using Echocardiography.

The investigators are going to monitor 200 patients in 2019 treated with the newly established fast-track concept. During the premedication visit, the investigators informed the patients that the intention is to perform the TF-TAVI, if acceptable, solely in local anaesthesia, in order to minimize potentially adverse pharmacological central effects by analgosedation. After insertion of two peripheral venous lines and an arterial line, monitoring of cerebral oxygenation using near-infrared spectroscopy was established. Transthoracic echocardiography has been performed to evaluate volume status, using the inferior vena cava collapsibility index. Additionally, cardiac output and ejection fraction was calculated.

Based on the data of the investigators and current data from the literature, the investigators assume a postoperative hospital stay of 8 days after TF-TAVI. With a possible reduction of the hospital stay by about 25%, the investigators calculated a case number of 100 patients per group. The study is designed with a control group under standard therapy. Data are recorded and analyzed descriptively. Qualitative comparisons will be made in the discussion of previously published data.
