Is local anesthesia the optimum strategy in retrograde transcatheter aortic valve implantation? A systematic review and meta-analysis.

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.
