First zero contrast PCI guided by intracoronary ultrasound in the Czech Republic

Area of Science:

• Cardiology
• Nephrology
• Medical Imaging

Background:

• Contrast-induced nephropathy (CIN) is a significant complication following coronary interventions, particularly in patients with advanced chronic kidney disease.
• The increasing prevalence of complex coronary interventions in elderly and comorbid patients necessitates strategies to minimize contrast media exposure.
• Minimizing contrast volume is essential to mitigate the risk of worsening renal function and adverse clinical outcomes.

Observation:

• A case report details a 68-year-old patient with chronic kidney disease undergoing elective percutaneous coronary intervention (PCI) for a left anterior descending artery lesion.
• Maximum emphasis was placed on reducing contrast media volume during the procedure.
• This represents a novel approach, potentially the first of its kind in the Czech Republic, employing intracoronary ultrasound (IVUS) guidance.

Findings:

• Intracoronary ultrasound (IVUS)-guided zero-contrast PCI was successfully performed, demonstrating feasibility in a patient with significant renal insufficiency.
• This technique allowed for visualization and intervention without relying on traditional angiography, thereby eliminating contrast administration.
• The procedure highlights a potential method to drastically reduce or eliminate contrast media in specific PCI scenarios.

Implications:

• IVUS-guided zero-contrast PCI may serve as a viable and safer alternative to standard angiography-guided PCI for high-risk patients.
• This approach has the potential to significantly reduce the incidence and severity of contrast-induced nephropathy.
• Further research and broader adoption of this technique could improve clinical outcomes for patients with chronic kidney disease undergoing coronary interventions.
