"DK Crush" Technique for a Tightly Stenosed Conjoined SVG Lesion in a Patient with Acute Coronary Syndrome and Cardiogenic Shock.

UNLABELLED: Coronary artery bifurcation disease of saphenous venous graft (SVG) is extremely rare. SVG disease remains a challenging lesion to treat because of increased morbidity and mortality with repeated coronary artery bypass graft surgery (CABG), high rates of periprocedural complications, and in-stent restenosis or occlusion requiring repeat revascularization with percutaneous coronary intervention. Herein, we present the first reported case of using the "DK crush" technique to treat an inverted Y-shaped SVG bifurcation disease in a patient with a prior CABG and new-onset acute coronary syndrome. Arising from our treatment, favorable immediate and mid-term angiographic and clinical outcomes were obtained. KEY WORDS: Coronary artery bypass surgery (CABG); "DK crush" technique; Saphenous venous graft (SVG).
