  • Title: [Transient left myocardial dysfunction: a cause of neonatal hypoxemia].
    Author: Feki H, Liet JM, Gournay V, Rozé JC.
    Journal: Arch Pediatr; 2002 May; 9(5):506-10. PubMed ID: 12053546.
    Abstract:
    UNLABELLED: Refractory hypoxemia in the newborn requires an accurate diagnostic investigation for an optimal and prompt management. CASE REPORT: After a short delivery, a post-term newborn developed a severe hypoxemia with patchy pulmonary alveolar opacities and systolic right-to-left extrapulmonary shunting through the ductus arteriosus. Echocardiography ruled out a cardiac malformation and showed dilated left atrium with left-to-right shunting by the ovale foramen due to left ventricular dysfunction. Inotropic support associated with mechanical ventilation allowed a rapid improvement. CONCLUSION: A pathophysiological analysis is needed in case of severe neonatal hypoxemia. Doppler ultrasound is a non invasive and rapid method allowing the adjustment of the therapeutic strategy.
