Comparison of Deep Sedation With General Anesthesia in Patients Undergoing Percutaneous Mitral Valve Repair

BackgroundPercutaneous edge‐to‐edge mitral valve repair (PMVR) has become an established treatment option for mitral regurgitation in patients not eligible for surgical repair. Currently, most procedures are performed under general anesthesia (GA). An increasing number of centers, however, are performing the procedure under deep sedation (DS). Here, we compared patients undergoing PMVR with GA or DS. Methods and ResultsA total of 271 consecutive patients underwent PMVR at our institution between May 2014 and December 2016. Seventy‐two procedures were performed under GA and 199 procedures under DS. We observed that in the DS group, doses of propofol (743±228 mg for GA versus 369±230 mg for DS, P<0.001) and norepinephrine (1.1±1.6 mg for GA versus 0.2±0.3 mg for DS, P<0.001) were significantly lower. Procedure time, fluoroscopy time, and dose area product were significantly higher in the GA group. There was no significant difference between GA and DS with respect to overall bleeding complications, postinter...
