Impaired Right Ventricular Function After Transcatheter Treatment of Tricuspid Regurgitation: Does It Matter?

JACC. Cardiovascular imaging·2026

Area of Science:

  • Cardiology
  • Medical Imaging

Background:

  • Echocardiography is a primary cardiac imaging tool.
  • Poor endocardial border definition limits echocardiography's diagnostic accuracy.

Purpose of the Study:

  • To evaluate the impact of contrast agents on echocardiography.
  • To assess the utility of contrast echocardiography in improving image quality and diagnostic capabilities.

Main Methods:

  • Intravenous injection of contrast agents to opacify cardiac chambers.
  • Acquisition and analysis of echocardiographic images with and without contrast.

Main Results:

  • Contrast echocardiography significantly improves endocardial border definition.
  • Enhanced assessment of global and regional wall motion.
