[Pediatric angiocardiography. Randomized, controlled study of 2 iodinated contrast media: iopromide 300 and ioxaglate 320 mgI/ml]

Area of Science:

• Pediatric cardiology
• Radiology
• Medical imaging

Background:

• Cardiac catheterization is a common procedure in pediatric patients.
• Ionic low osmolar contrast media like ioxaglate are frequently used.
• Non-ionic contrast media offer potential advantages in terms of safety and tolerability.

Purpose of the Study:

• To compare the safety and efficacy of iopromide 300 (non-ionic) versus ioxaglate 320 mgI/ml (ionic low osmolar) in pediatric cardiac catheterization.
• To evaluate the incidence of adverse effects associated with each contrast medium.

Main Methods:

• Prospective randomized trial involving 31 children.
• Comparison of iopromide 300 and ioxaglate 320 mgI/ml during cardiac catheterization.
• Analysis of adverse events and allergoïd reactions.
• Meta-analysis of a multicenter study to confirm findings.

Main Results:

• Fewer adverse effects were observed with iopromide compared to ioxaglate.
• No statistically significant difference in adverse effects was found between the two contrast media in this small population.
• A very low incidence of allergoïd reactions was noted for both agents.
• Meta-analysis supported the observed tendency of fewer adverse effects with iopromide.

Conclusions:

• Iopromide may be associated with a lower incidence of adverse effects in pediatric cardiac catheterization compared to ioxaglate.
• Larger studies are needed to confirm the statistical significance of this finding due to the small sample size.
• Both contrast media demonstrated a low incidence of allergoïd reactions, suggesting good overall safety profiles.
