The patient underwent planned left main coronary intervention on (b)(6) 2010, having undergone diagnostic coronary angiography at another hospital several days earlier.During the coronary intervention, following deployment of two drug eluting stents to reconstruct the left main bifurcation, the patient sustained a perforation of the left main coronary artery, associated with hemodynamic collapse.Vasopressor therapy was begun and subxiphoid pericardiocentesis was performed to drain the hemopericardium.Due to ongoing hemorrhage from the left main coronary artery, the stent loosened from its deployment balloon and embolized to the mid portion of the left anterior descending artery.A second graftmaster stent was then advanced and deployed in the left main coronary artery, but the patient became asystolic nonetheless, and expired.At the time of the event, the manufacturer was notified and the manufacturer submitted a full report to the fda.I was made aware of this adverse event on january 24, 2016, following an internal audit of this protocol's activity.
