Preoperative PAPI in Right Ventricular Failure After LVAD Injection

There's actually very limited evidence using PAPI clinically in the LVAD patient population. And then I think Dr. Essendow kind of mentioned it before, but there really is no established cutoff that we can use in this patient cohort to guide management appropriately. All right. Nick, why don't you tell us a little bit about what led you to do or your team to do this systematic review? What were you looking for? Of course, yeah. The pulmonary artery positivity index could have an important role in identifying patients at risk for right reticular failure following LVAD implantation.
