Why the study?
Does local anesthesia improve outcomes or reduce procedural duration and hospital stay compared to general anesthesia in patients undergoing retrograde TAVI?
Does local anesthesia improve outcomes or reduce procedural duration and hospital stay compared to general anesthesia in patients undergoing retrograde TAVI?
Local anesthesia for retrograde TAVI is feasible and associated with shorter procedural duration, shorter hospital stay, and lower vasopressor requirements compared to general anesthesia, without differences in mortality or complications.
Supports preferring local anesthesia for retrograde TAVI to shorten procedures and stays; extends evidence of equivalent safety.
BACKGROUND: Retrograde transcatheter aortic valve implantation (TAVI) can be performed under local anesthesia (LA) or general anesthesia (GA); however, a wide variation in practice exists. METHODS: PubMed was searched between 2009 and 2013. Data were extracted from eligible studies. Random-effects meta-analysis was performed using DerSimonian Laird between-study variance. RESULTS: There was no statistically significant difference identified between groups based on age or EuroSCORE. There was no statistically significant difference seen in all-cause mortality, or complication rates between groups. Mean procedural duration was 36 minutes shorter in the LA group (p = 0.001). There was increased vasopressor use in the GA group (odds ratio 3.92; p = 0.017). Mean hospital stay was 3.41 days shorter in the LA group (p = 0.018). CONCLUSION: Results suggest that the use of LA for retrograde TAVI is feasible. There are several potential benefits associated, shorter procedural duration, and hospital stay with lower vasopressor requirements. Further studies and randomized trials are mandatory to confirm the presented findings and to identify those patients for whom LA would be appropriate.
