[Neonatal nonbacterial thrombotic endocarditis].

Unlabelled: Nonbacterial thrombotic endocarditis is not widely known in neonates.

Case Reports: We report three new cases which illustrate some specific aspects of this pathology. Respiratory distress with severe pulmonary hypertension, systemic hypotension and disseminated intravascular coagulopathy in a full-term newborn were characteristic findings.

Conclusion: An early echocardiography should lead to accurate diagnosis. Hypoxemia and genetic factors could be determining factors in its pathogenesis.
