STRATEGY for Left Main Coronary Bifurcation Lesion II

Not Applicable
Completed
Conditions
Coronary Artery Disease
Registration Number
NCT01798433
Lead Sponsor
Samsung Medical Center
Brief Summary

In patients with unprotected left main (LM) true bifurcation lesion (cohort A), elective 2-stent strategy is superior to provisional strategy at preventing the occurrence of 12-month target lesion failure after percutaneous coronary intervention for bifurcation lesion.

In patients with unprotected LM non-true bifurcation lesion (cohort B), 1-stent technique with mandatory final kissing ballooning is superior to 1-stent technique without kissing ballooning at preventing the occurrence of 12-month target lesion failure after percutaneous coronary intervention for bifurcation lesion.

Primary Outcome Measures
NameTimeMethod
Target lesion failure12-month

defined ad a composite of cardiac death, spontaneous MI or target lesion revascularization

Secondary Outcome Measures
NameTimeMethod
Procedure timeimmediate after PCI
Cardiac death12-month

All deaths were considered cardiac unless a definite non-cardiac cause could be established.

Angiographic in-segment restenosis rate9 months

as measured by 9-month quantitative coronary analysis

Target vessel revascularization (TVR)12-month

TVR was defined as repeat revascularization of the target vessel by PCI or bypass graft surgery.

Stent thrombosis12-month

Stent thrombosis was assessed based on the definitions of the Academic Research Consortium as definite, probable, or possible stent thrombosis.

Myocardial infarction (MI)12-month

MI was defined as elevated cardiac enzymes (troponin or MB fraction of creatine kinase, CK-MB) more than the upper limit of the normal value with ischemic symptoms or electrocardiography findings indicative of ischemia that was not related to the index procedure.

Target lesion revascularization (TLR)12-month

TLR was defined as repeat PCI of the lesion within 5 mm of stent deployment or bypass graft surgery of the target vessel.

Periprocedural CK-MB elevationthe first 48 hours after PCI

Periprocedural enzyme elevation was defined as a rise in CK-MB ≥3 times the upper normal limit after the index procedure.

Procedure success ratethe first 48 hours after PCI
Amount of contrast dyeimmediate after PCI
