Remimazolam Requires Less Vasopressor Support during Induction and Maintenance of General Anesthesia in Patients with Severe Aortic Stenosis Undergoing Transcatheter Aortic Valve Replacement: A Retrospective Analysis from a Single Center

Table 4

Changes in mean PA pressure, SvO2, and CI during surgery. There was no difference between the three groups. Values are shown as the median [interquartile range] or number (%). A was considered to indicate statistical significance. BAV: balloon aortic valvuloplasty; mPA: mean pulmonary artery pressure; SvO2: mixed venous oxygen saturation; CI: cardiac index.
