Meta AnalysisGeneral Anesthesia Versus Local Anesthesia in Patients Undergoing Transcatheter Aortic Valve Replacement: An Updated Meta-Analysis and Systematic Review.
For patients with aortic stenosis, transcatheter aortic valve replacement (TAVR) offers a less invasive treatment modality than conventional surgical valve replacement. Although the surgery is performed traditionally under general anesthesia (GA), recent studies have described success with TAVR using local anesthesia (LA) and/or conscious sedation. The study authors performed a pairwise meta-analysis to compare the clinical outcomes of TAVR based on operative anesthesia management. ⋯ Transcatheter aortic valve replacement performed using LA is associated with lower rates of adverse clinical outcomes, including 30-day mortality and stroke. No difference was seen between the 2 groups for a 30-day paravalvular leak. These results support the use of minimally invasive forms of TAVR without GA.

Randomized Controlled TrialEffect of Dexmedetomidine on Postoperative Renal Function in Patients Undergoing Cardiac Valve Surgery Under Cardiopulmonary Bypass: A Randomized Clinical Trial.
The effect of dexmedetomidine on postoperative renal function was investigated in patients undergoing cardiac valve surgery under cardiopulmonary bypass (CPB). ⋯ Dexmedetomidine may be considered as a way to reduce the incidence and severity of postoperative AKI in patients undergoing cardiac valve surgery under cardiopulmonary bypass.
