Does right atrial injection of contrast achieve successful myocardial opacification during two-dimensional echocardiography in open-chest anesthetized dogs?
Successful and reproducible myocardial opacification can be achieved during myocardial contrast echocardiography after right atrial injection of contrast, demonstrating feasibility for broader application.
Villanueva et al. (1992) studied this question.
