Study Summary

The study aims to answer whether the use of a mixture of blood and saline alone (limited air) provides the same degree of right-heart contrast enhancement as compared to the standard agitated saline (with air), during two types of echocardiograms.

Primary Outcome

The degree of right atrial opacification during echocardiogram will be rated with an image score; 0: poor/no opacification, 1: average opacification, 2: good opacification

Interventions

  • PROCEDURE Transesophageal Echocardiogram (TEE)
  • PROCEDURE Transthoracic Echocardiogram (TTE)
  • OTHER Saline/Air Mixture
  • OTHER Saline/Blood Mixture
