Closed chest transauricualr embolization EMI model. (A) An angled 4Fr hydrophilic cathater has been introduced retrograde to the aortic root after transauricular intra-arterial access of the right common carotid artery. Asterisk denotes the orifice of the LAD during contrast coronary angiogram obtained at 6 frames per second. (B) An 0.018 soft hydrophilic guidewire has been advanced in the distal LAD to guide insertion of a 2.4Fr Progreat microcatheter (Terumo, Japan). (C) The microcathater has been advanced to the level of the distal third segment of the LAD and beyond the origin of the diagonal branch and a 2 mm micro-coil is being delivered (white arrowhead). (D) Final contrast coronary angiogram shows micro-coil (white arrowhead) in situ after removal of the microcatheter (whole coronary catheterization and coil embolization procedure lasts < 3 min).
