DK crush technique in a calcified LAD-diagonal bifurcation - LIVE case
Recommended by PCRSummary
A 53‑year‑old man with hypertension and dyslipidemia presented with an inferior MI treated with primary PCI of the RCA two months earlier. He was referred for staged treatment of a significant calcified LAD–diagonal bifurcation lesion.Lesion preparation included non‑compliant balloon dilatation, rotational atherectomy in the LAD (1.5 and 1.75 mm burrs), and intravascular lithotripsy (IVL) in the diagonal branch. A DK‑crush technique was then performed with implantation of two stents, guided by OCT.
