Commentator Discussion: Autonomous Fontan Pump: Computational Feasibility Study

Ohio).So, my questions are, 1, you talk to us a lot about the cavopulmonary difference between normal and a Fontan is about 10.But most of your pumps or the different variations have always just tried to get 2. Why don't we try to normalize that gradient and go back to 10?Dr Mark Rodefeld (Indianapolis, Ind).So, the motorized pump that's in development can deliver 10 mm Hg pressure rise.I think it's not yet clear how much pressure exactly a person would tolerate or would be ideal, but that pump can generate up to even 20, 25, 30 mm Hg if necessary.I think the sweet spot for full cavopulmonary assist is probably in the þ7 mm Hg range in a generally healthy patient.This self-powered pump is never going to perform at that level.This pump
