E-068 Assessment of cell yield among different devices for endovascular biopsy to harvest endothelial cells

Conclusion Among devices studied for EC harvesting, PCRs and stentrievers yield more cells than other devices. PCRs appear more suitable for harvesting ECs in small vessels, while stentrievers are better for harvesting from large vessels. Further study of these devices for EC sampling is warranted to initiate and refine its use in humans for this purpose.
