Does pulsed Doppler echocardiography accurately diagnose patent ductus arteriosus in infants with heart disease compared to invasive documentation?
Precordial pulsed Doppler echocardiography is a highly sensitive and specific non-invasive method for diagnosing patent ductus arteriosus in infants, potentially replacing the need for invasive documentation.
Stevenson et al. (1980) studied this question.
