Case Summary

ACS patients with significant unprotected LMCA disease represent one of thr most high risk type of CADIn patients with ACS,LMCA targeted PCI is associated with high risk of cardiac death,MI,instent thrombosi,strokeDistal LM bifurcation lesions pose considerable challenges and require unique approaches for optimal resultAn integrated approach that comines pre procedure planning with intracoronary imaging,improves success rates and long term clinical outcomes
