title: Assessment of coronary artery intimal thickening in patients with a previous diagnosis of Kawasaki disease by using high resolution transthoracic echocardiography: our experience.
abstract: BACKGROUND
  Kawasaki disease (KD) is a generalized systemic vasculitis of unknown etiology involving medium and small size blood vessels, particularly the coronary arteries. In these vessels a progressive stenosis may result from active remodeling with an intimal proliferation and neoangiogenesis. The aim of our study was to assess, by using high-resolution transthoracic 2D Echocardiography, if subjects with a previous diagnosis of Kawasaki disease after several years show a coronary intimal thickening, suggestive of a persistent cardiovascular risk.
  
  
  METHODS
  We assessed measurement of thickening, inner diameter and outer diameter of coronary arteries using 2D Echocardiography (Philips E 33 with multy-frequency S8-3 and S12-4 probes) and examining the proximal portion of left main coronary artery just above the aortic valve with parasternal short axis view.
  
  
  RESULTS
  We found a significant intimal thickening in patients with previous Kawasaki disease compared to healthy controls. In particular, we noticed that also subjects not suffering from coronary impairment in acute phase have higher values of thickening than healthy controls, and this wall thickening may confer a higher cardiovascular risk.
  
  
  CONCLUSIONS
  Therefore we concluded that the assessment of coronary artery thickening by high-resolution transthoracic 2D Echocardiography may become an essential instrument to evaluate late cardiovascular risk in subjects with a diagnosis of Kawasaki disease in childhood.
