Captured external expert commentary on this paper, strongest first. Original sources are linked where available.
“Traditionally, the LAMPOON technique and its various iterations has been used to enable TMVR in patients at high risk of LVOT obstruction; however, this technique has a steep learning curve and is technically more challenging and time-consuming. The findings from this study highlight that BATMAN may be considered as an alternative to LAMPOON associated with excellent efficacy and safety, particularly for ViR and ViV procedures, providing another option for physicians.”
“In this international, multicenter cohort study, BATMAN was technically feasible, associated with short procedural times, and highly effective in enabling TMVR in patients at high risk of LVOT obstruction.”
“We need to get better at predicting LVOT geometry after TMVR.”
