Abstract
Ultrasound enhancing agents (UEAs), including Optison, Definity, and Lumason, enhance the diagnostic performance of echocardiography, particularly in patients with suboptimal acoustic windows. However, there remains a paucity of comparative safety assessments among the Food and Drug Administration (FDA)-approved UEAs. A PRISMA-guided systematic literature review performed in August 2023 searched Medline, Embase, Cochrane Library, and grey literature. Randomized and non-randomized comparative evidence on safety of contrast enhanced procedures were included. A feasibility assessment ensured homogeneity across studies by comparing patient characteristics and outcomes. Bayesian hierarchical network meta-regression was employed to indirectly compare published safety outcomes across different UEAs. In addition, adverse events (AEs) between 2019-2023 for each UEA were retrieved from the FDA Adverse Events Reporting System (FAERS), and comparative safety outcomes were derived using annual UEA administration in the US. Screening of 4146 records rendered 19 studies for inclusion in the indirect comparison analysis after feasibility assessment. Optison demonstrated favorable safety in direct comparisons with Definity and Lumason across the majority of investigated AEs. Network meta-regression results on serious adverse events (SAEs) within 30 minutes revealed odds ratios (ORs) of 0.59 (95% confidence interval: 0.27-1.23) and 0.63 (0.29-1.33) for Optison vs. Lumason and Definity, respectively, indicating a decreased risk of SAEs for Optison vs. Lumason and Definity, further supported by statistically significant ORs within FAERS: 0.01 (0-0.02), P<0.001 and 0.15 (0.05-0.48), P=0.001, for Optison vs. Lumason and Definity, respectively. In conclusion, our results restate the favorable comparative safety profile of Optison, providing new evidence to inform clinical decision-making.
