Successful Treatment of Unprotected Left Main Coronary Bifurcation Lesion Using Minimum Contrast Volume with...

Area of Science:

• Cardiology
• Interventional Cardiology
• Nephrology

Background:

• Contrast-induced nephropathy (CIN) is a significant risk following percutaneous coronary intervention (PCI), increasing patient morbidity and mortality.
• Minimizing contrast medium volume is a key strategy for CIN prevention.
• Intravascular ultrasound (IVUS) offers an alternative imaging modality to reduce contrast use during PCI.

Observation:

• A case report details the successful treatment of an elderly patient with a complex, unprotected left main bifurcation lesion.
• The lesion was heavily calcified and diffuse, posing a significant interventional challenge.
• IVUS-guided PCI was employed, utilizing a remarkably low volume of contrast dye (12 cc).

Findings:

• The IVUS-guided PCI procedure was technically successful in managing the complex left main bifurcation lesion.
• The use of IVUS facilitated precise guidance, enabling a significant reduction in contrast agent administration.
• The patient tolerated the procedure well, with no immediate complications related to CIN.

Implications:

• This case highlights the potential of IVUS-guided PCI as a viable strategy for CIN prevention in high-risk patients.
• Utilizing IVUS can enable complex PCI procedures with substantially reduced contrast volumes.
• Further research into IVUS-guided techniques may optimize patient outcomes and reduce risks associated with contrast media in interventional cardiology.
