Why the study?
Does right atrial inversion on echocardiography accurately diagnose cardiac tamponade in patients with moderate or large pericardial effusions?
Does right atrial inversion on echocardiography accurately diagnose cardiac tamponade in patients with moderate or large pericardial effusions?
Right atrial inversion, particularly when prolonged (time index >0.34), is a highly sensitive and specific novel echocardiographic marker for diagnosing cardiac tamponade.
No takes yet. Share an insight, caveat, or question.
May aid tamponade diagnosis on echo in moderate-large effusions; hypothesis-generating, requiring prospective validation before practice change.
Gillam et al. (1983) studied this question.
