Kameyama A, et al. - In patients with transcatheter aortic valve replacement (TAVR), authors ascertained the associations between intraoperative hemodynamic parameters and delayed hemodynamic recovery following valve deployment. By focusing on intraoperative hemodynamics, they also assessed the predictive factors of delayed hemodynamic recovery. Participants were 64 patients who underwent elective TAVR between 2015 and 2017. Findings suggested the utility of ScvO₂ monitoring during TAVR to foresee delayed recovery greater than 60 seconds following valve deployment in TAVR. After induction of anesthesia, ScvO₂ in the delayed recovery (DR) group was not lower vs that in the early recovery (ER) group. Nonetheless, they noted a gradual decrease in the ScvO₂ in the DR group and it was lower than that in the ER group prior to valve deployment, regardless of improvement in blood pressure via the administration of vasopressor agents.
