Immediate, Short-Term, Intermediate, and Long-Term Clinical Outcomes of True Bifurcation Stenting

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Medicine

Background:

• Coronary artery bifurcation lesions present higher risks than non-bifurcation lesions.
• These lesions can negatively impact patient prognosis and increase adverse event rates.

Purpose of the Study:

• To evaluate the clinical efficacy of various stenting techniques for true bifurcation lesions.
• To assess immediate, short-term, intermediate, and long-term outcomes associated with these techniques.

Main Methods:

• Retrospective observational cohort study (February 2015 - February 2021).
• 172 patients with true bifurcation lesions undergoing percutaneous coronary intervention (PCI).
• Three-year follow-up to evaluate procedural outcomes.

Main Results:

• Drug-eluting stents demonstrated good procedural success.
• Major adverse cardiac events (MACE) were significantly associated with acute coronary syndrome (ACS) and prior PCI (p < 0.000).
• Final kissing balloon inflation, stenting technique, and bifurcation involvement correlated with MACE (p < 0.01); mortality was 1.16%.

Conclusions:

• The two-stent strategy is a viable option for true bifurcation lesions.
• This approach yields favorable long-term outcomes with a low rate of complications.
