Ultra-Low Contrast Balloon-Embedded PCI for Acute LMCA Occlusion With Quadrifurcation Anatomy in a...

Area of Science:

• Interventional Cardiology
• Vascular Medicine
• Cardiovascular Surgery

Background:

• Acute left main coronary artery occlusion is a rare and life-threatening condition.
• Quadrifurcation anatomy presents unique challenges for treatment.
• High mortality rates are associated with left main coronary artery occlusions.

Observation:

• A patient presented with acute thrombotic occlusion of the left main coronary artery with quadrifurcation anatomy.
• The occlusion was successfully treated using an ultra-low contrast (25 mL) provisional single-stent strategy.
• A balloon-embedded technique was employed during the stenting procedure.

Findings:

• Six-month follow-up angiography showed a patent stent in the left main coronary artery.
• Lesions in the diagonal branch, left circumflex artery, and obtuse marginal branch remained angiographically unchanged.
• The patient exhibited improved left ventricular function and sustained clinical stability.

Implications:

• Provisional stenting is a feasible strategy for complex quadrifurcation lesions.
• Ultra-low contrast techniques can be effective in managing coronary artery occlusions.
• This approach demonstrates potential for successful outcomes in resource-constrained settings.
