title: Value of the echocardiographic suprasternal view for diagnosis of patent ductus arteriosus subtypes.
abstract: OBJECTIVE
  The purpose of this study was to explore the value of the transthoracic echocardiographic suprasternal view in the diagnosis of patent ductus arteriosus subtypes.
  
  
  METHODS
  Sixty-five patients with a patent ductus arteriosus were examined using transthoracic echocardiographic suprasternal and parasternal views before ductus arteriosus closure. Diameters of the aortic and pulmonary sides of the ductus arteriosus were measured, and subtype diagnoses were made. The results were compared with those from digital subtraction angiography.
  
  
  RESULTS
  The mean diameters ± SD of the aortic side of the ductus arteriosus were 8.31 ± 2.76, 10.87 ± 3.26, and 11.15 ± 3.29 for the parasternal view, the suprasternal view, and digital subtraction angiography, respectively, whereas the diameters of the pulmonary side were 5.69 ± 2.82, 5.75 ± 2.63, and 6.09 ± 2.78 mm. Of the 65 cases, 12, 19, and 19 were the funnel-type patent ductus arteriosus as evaluated with the parasternal view, the suprasternal view, and digital subtraction angiography. Detection on the parasternal view was lower than that on the suprasternal view (χ(2) = 5.14; P < .025).
  
  
  CONCLUSIONS
  The diameter of the aortic side of a patent ductus arteriosus can be accurately detected on the superasternal view, which would be helpful for diagnosis of patent ductus arteriosus subtypes.
