IVUS VS CAG Guided PCI for Patients With LMB Lesion

Status Not yet recruiting

Clinical Trial Summary

To compare the 3 - year clinical follow - up results of patients with left main bifurcation lesions treated by intravascular ultrasound(IVUS) - guided and coronary angiography(CAG) - guided percutaneous coronary intervention(PCI), and to confirm the clinical benefits of optimizing interventional therapy of left main bifurcation lesions by intravascular ultrasound(IVUS).

Clinical Trial Description

616 patients with primary left main coronary artery bifurcation lesions will be recruited in this study. The target lesions of patients need to be true coronary artery bifurcation lesions (Medina 1,1,1 or 0,1,1). After angiography, patients will be randomly assigned to intravascular ultrasound(IVUS) - guided and coronary angiography (CAG)- guided groups. The random number of patients will be generated by the central computer random system, and the random will be stratified according to the study sites. In coronary angiography(CAG)-guided group, two-stent technique will be used(the exact two-stent technique used was left to the operator's discretion). In intravascular ultrasound(IVUS)-guided group, minimal lumen area(MLA) in ostium of side branch will be measured by intravascular ultrasound(IVUS). If minimal lumen area(MLA)<4mm2, two-stent technique will be used(the exact two-stent technique used was left to the operator's discretion) and intravascular ultrasound(IVUS) will be repeated at the end of the procedure. If minimal lumen area(MLA) >=4mm2, one-stent technique will be used and intravascular ultrasound(IVUS) will be repeated. If minimal lumen area(MLA) in ostium of side branch is still >=4mm2, the procedure will be ended. If minimal lumen area(MLA) in ostium of side branch become <4mm2, the following interventional strategy will be left to the operator's discretion( balloon inflation, drug-eluting balloon, or switch to two-stent technique). Again, intravascular ultrasound(IVUS) will be repeated at the end of the procedure. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
