Summary
Double-kissing (DK) crush stenting is the most effective strategy for complex left main bifurcation disease, significantly reducing risks of myocardial infarction and major adverse cardiovascular events (MACE). This approach offers durable outcomes, supporting its use in challenging cases with expert follow-up.
Area of Science:
- Interventional Cardiology
- Cardiovascular Surgery
- Biomedical Engineering
Background:
- Percutaneous coronary intervention (PCI) for distal left main bifurcation disease is complex due to intricate anatomy and high ischemic risk.
- The optimal stenting technique for these challenging cases remains uncertain, necessitating comparative analysis.
Purpose of the Study:
- To compare the efficacy and safety of various stenting strategies for distal left main bifurcation PCI.
- To identify the optimal technique for reducing adverse cardiovascular events in this patient population.
Main Methods:
- A frequentist random-effects network meta-analysis of 15 studies involving 3794 patients.
- Compared provisional stenting, double-kissing (DK) crush, classic crush, minicrush, culotte, T-stenting, TAP, and nanocrush.
- Primary outcome: all-cause mortality. Secondary outcomes: cardiac death, myocardial infarction, stent thrombosis, target lesion revascularization, target vessel revascularization, and major adverse cardiovascular events (MACE).
Main Results:
- DK crush ranked highest for efficacy and safety outcomes.
- DK crush showed significantly lower risks of myocardial infarction, target lesion revascularization, target vessel revascularization, and MACE compared to classic crush.
- Culotte stenting was linked to a higher risk of stent thrombosis; no significant differences in mortality were observed across strategies.
Conclusions:
- DK crush is the most effective and durable bifurcation strategy for distal left main PCI.
- This technique reduces ischemia-driven revascularization and MACE, supporting its preferential use in complex lesions.
- Operator expertise and long-term follow-up are crucial for successful implementation of DK crush.
