    Notes: Abstract Objective: To evaluate whether a trial of inhaled nitric oxide (NO) differentiates reversible pulmonary vasoconstriction from fixed anatomic obstruction to pulmonary blood flow after surgery for congenital heart disease in patients at risk for pulmonary hypertension.¶Design: Prospective cohort study.¶Setting: Tertiary care children's hospital.¶Patients: 15 neonate and infants with elevated pulmonary artery or right ventricular pressure or with clinical signs suggestive of high pulmonary vascular resistance in the early postoperative period following repair of congenital heart disease.¶Intervention: 30-min trial of 40 ppm inhaled NO.¶Results: 5 patients responded to inhaled NO, 2 patients were weaned from extracorporeal support with NO. Four were maintained on continuous inhaled NO for 3 to 5 days. All the responders survived. Ten patients did not respond to NO. An important anatomic obstruction was found with echocardiography or angiography in all 10 patients. Reintervention was performed in 6/10 (4 stent placement, 1 balloon angioplasty of pulmonary arteries and 1 revision of systemic to pulmonary shunt). Six of the nonresponders died.¶Conclusion: A trial of inhaled NO after cardiac surgery in neonates and infants may be useful to differentiate reversible pulmonary vasoconstriction from fixed anatomic obstruction and may provide useful information if temporary support with extracorporeal membrane oxygenation is considered. Failure to respond to inhaled NO should prompt further investigations to rule out a residual obstruction.

    Notes: Abstract. This report illustrates the rare occurrence of a pulmonary embolus in a neonate during cardiac catheterization. The patient was a term newborn who underwent repair of obstructed infradiaphragmatic total anomalous pulmonary venous connection. Postoperative risk factors for pulmonary embolism included severe pulmonary hypertension unresponsive to nitric oxide therapy, an indwelling venous catheter, and young age. Successful management was achieved by initial mechanical fragmentation with streptokinase infusion and monitoring by serial lung perfusion scans.
