A patient was referred for PCI of an LAD CTO with an ambiguous proximal cap at the takeof of a septal. IVUS-guided antegrade puncture failed causing a small wire perforation. A balloon was inflated sealing the perforation. Retrograde via septal collaterals from the PDA and via an epicardial collateral from a diagonal failed. The side-BASE technique was used: a balloon was inflated partially inside the LAD and partially inside the diagonal and a knuckled Gladius Mongo wire was advanced extraplaque through the proximal cap. Reentry into the distal true lumen was achieved using the stick and drive technique with a Gaia 3rd wire with an excellent final result after stenting.
