[Bronchiolitis and pulmonary hypertension].

Objectives: The study was undertaken to assess whether previously healthy infants with bronchiolitis develop elevated pulmonary artery pressures.

Material And Methods: We performed 2D and Doppler echocardiography in 94 infants, aged between 2 and 12 months, from November 2007 to December 2009. 47 infants had bronchiolitis and 47 were in the control group.

Pulmonary hypertension during acute respiratory diseases in infants.

Objectives: The study was undertaken to assess whether previously healthy infants with acute respiratory diseases develop elevated pulmonary artery pressures and to identify which type of disease is associated with pulmonary hypertension.

Material And Methods: We performed 2D and Doppler echocardiography in 137 infants, aged between 1 and 12 month, from November 2007 to December 2009. 75 infants had acute respiratory diseases (49 bronchiolitis, 16 interstitial pneumonia, 3 bronchopneumonia, 6 episodic wheezing, 1 lobar pneumonia) and 62 were in the control group.
