M-mode contrast IVC imaging may aid ECG-timed differentiation of tricuspid insufficiency; hypothesis-generating and requires prospective validation before practice change.
Does contrast M-mode ultrasonography improve the differentiation of tricuspid insufficiency from impaired right ventricular filling compared to two-dimensional ultrasonography in patients with cardiac disorders?
Contrast M-mode ultrasonography of the inferior vena cava allows precise ECG correlation to differentiate tricuspid insufficiency from impaired right ventricular filling.
