Abstract:
The lesion of the left main coronary artery(LM)itself is one of the challenges of interventional therapy.If the lesion is combined with calcification,the interventional therapy is difficult to operate and extremely risky.This case report presents a 77-year-old elderly male patient.Coronary angiography(CAG)indicated severe stenosis of the LM-left anterior descending(LAD)accompanied by severe calcified bifurcation lesions.After pre-dilation,percutaneous coronary intraluminal shock wave balloon catheter angioplasty(IVL)was applied for treatment.Before IVL treatment,the LM-LAD lesion was subjected to ischemic preconditioning by using an appropriate balloon to fix the pressure and gradually upgrading the balloon dilation time.Later,a Cross-over procedure was performed to implant a single stent,achieving satisfactory results.Among them,the ischemic preconditioning methods for LM lesions can provide reference significance for clinicians.
