As i know of right now, dr.(b)(6) was using a suoh-03 across an epicardial collateral.I do not know if it was rca to lca or vice-versa.Apparently, as he was advancing a mc (do not know which one), the tip of the suoh broke off into the collateral vessel.He was able to successfully retrieve the tip and they do have the wire.I am waiting on more information to come back from kate muller (ccl manager).
