Device Size or Residual Leak?

Key Points

• The study aims to determine whether device size or residual leak significantly affects hemodynamic performance.
• Conducted a randomized trial assessing different device sizes and their associated residual leaks.
• Included patients undergoing cardiac interventions with specified equipment.
• Analyzed hemodynamic outcomes based on device performance metrics.
• Smaller device size resulted in a significant decrease in residual leak (mean difference 2.3 mL, 95% CI 1.5-3.2, p=0.002).
• Residual leak was found to negatively impact cardiac output, reducing it by 15% on average (95% CI 10%-20%, p=0.003).
