Intrapericardial teratoma in newborn babies.

We report two cases of intra pericardial tumor with pericardial effusion, diagnosed in utero by echocardiography at 21 and 28 weeks of gestation. Both fetuses underwent an intra uterine pericardiocentesis to treat a hydrops fetalis. Surgical resection of the tumor was undertaken immediately after birth and histological description reported cystic teratoma. Both babies had a favorable post operative course.

[Use of oral sildenafil (Viagra) in pulmonary hypertension after cardiac pediatric surgery]. / Intérêt du sildénafil (Viagra) per os en cas d'hypertension artérielle pulmonaire après chirurgie cardiaque pédiatrique.

Pulmonary hypertension remains a major cause of morbidity after cardiac surgery, although inhaled nitric oxide (iNO) was shown to have clinical benefit. Some patients are dependent on iNO, increasing the length of hospital stay. The authors report a case of a girl, nine years old (17 kg), with mitral insufficiency, atrial septal defect and pulmonary hypertension (80% of systemic pressure). Following cardiac surgery, pulmonary hypertension persisted and iNO could not be withdrawn. Sildenafil was administered orally (1,5mg x kg(-1), every 4 h) at the 15th postoperative day and iNO could be withdrawn within 24h with clinical improvement.
