Rapid recurrence of an inflammatory myofibroblastic tumor in the right ventricular outflow tract.

We describe an unusual case of rapid recurrence of a previously excised inflammatory myofibroblastic tumor of the right ventricular outflow tract in a 5-month-old infant. The infant is asymptomatic 18 months after the second surgery. The very rare cardiac involvement, and the early relapse of the inflammatory pseudotumor, to the best of our knowledge, is a unique combination. The inflammatory myofibroblastic tumor, as known as a pseudotumor or plasma cell granuloma is an uncommon reactive lesion with unknown aetiology. It is found most commonly in the lung and a number of visceral organs, such as the spleen, liver, ileum, salivary glands, urinary bladder, larynx or brain or in the retroperitoneum and lymph nodes. To our knowledge only 9 cases have been published of such tumor arising within the heart.

Mitral valve anomalies obstructing left ventricular outflow.

This paper reports on two cases of more uncommon types of subaortic stenosis. A 2-year-old boy was found with accessory mitral valve leaflet (AMVL) attaching to the anterior leaflet, ballooning into the subaortic ventricular septum associated with a discrete subaortic membrane. The obstruction was successfully relieved by removal of the AMVL and resection of the membrane. A 19-day-old newborn with accessory tissue on the mitral valve (AMVT) causing subaortic stenosis, subaortic ventricular septal defect (VSD) and patent ductus arteriosus was operated on successfully. Accessory tissue excision through the VSD, VSD patch closure and ductus ligation were performed.

Surgical management of pulmonary atresia with intact ventricular septum. Right ventricular size as a guideline for surgical intervention.

61 infants with critical valvular pulmonary stenosis (21 cases) or pulmonary atresia with intact ventricular septum (40 cases) were operated on between 1975-1989 in the Semmelweis University Medical School. Right ventricular volume, area, outflow tract dimension and tricuspid anulus diameter was measured by angiocardiography and echocardiography to evaluate right ventricular size, and to predict the operative outcome using these data. Our results suggested, that if the normalized right ventricular volume was less than 3 ml/m2, the normalized right ventricular area was less than 2.5 cm2/m2, and the normalized right ventricular area was less than 2.5 cm2/m2 and the normalized tricuspid anulus diameter was less than 1.2 cm2/m2/3 only a systemopulmonary shunt procedure is needed. In all other cases pulmonary valvotomy is necessary to decompress the right ventric and to help increase the right ventricular size. Where a different part of the right ventricle is hypoplastic a systemopulmonary shunt procedure is needed too. In the follow up period the right ventricular dimension and tricuspid valve diameter was measured by echocardiography. This noninvasive assessment can predict the preoperative diagnosis, postoperative outcome and demonstrates an adequate growth of the right ventricle after pulmonary valvotomy.

Stenosis of pulmonary veins with total left anomalous pulmonary venous return.

A case of congenital stenosis of the pulmonary veins and total left anomalous pulmonary venous return is reported. There was also obstruction between the left pulmonary veins and left vena cava superior. The diagnosis was based on 2-dimensional and Doppler echocardiography and was confirmed by angiocardiography. The 6-month-old baby with these anomalies was operated upon successfully. These cardiac malformations are very rare separately and their combination has not been previously reported.

Thrombotic lesions of the tricuspid valve in a newborn: surgical management.

Thrombotic lesions on the leaflets of the tricuspid valve in a premature infant with an anatomically normal heart are described. The diagnosis was made by two-dimensional and Doppler echocardiography. No etiologic explanation could be obtained from the history and clinical findings. The newborn had no infection, no antithrombin deficiency, and no indwelling catheter through either a peripheral, central or umbilical vein. The multiple masses were successfully removed by surgery under deep hypothermic circulatory arrest at 1 month of age. The child is well, without neurological deficit, and is developing normally.

Congenital vascular rings: surgical management of 111 cases.

Between October 1974 and May 1987, 111 congenital vascular rings were submitted to surgical correction. There were 83 infants (age: 5 days-12 months, median: 7 months; weight: 1.9-8.5 kg, median: 7.1 kg), and 28 children (age: 1-13 years, median: 3.5 years; weight: 7.5-48 kg, median: 26.5 kg). Patients were divided into five groups: (1) double patent aortic arch (44 cases), (2) double aortic arch with atresia in different parts of the left arch (36 cases), (3) right aortic arch with left ligamentum arteriosum (21 cases), (4) left aortic arch with aberrant right subclavian artery and truncus caroticus (8 cases), and (5) pulmonary artery sling (2 cases). We had no intraoperative mortality but in the postoperative period, 2 neonates died of severe bacterial infections of the respiratory tract.

Candida endocarditis in an infant.

Infective endocarditis is a rare disease in infants. A 1-year-old boy with a large Candida albicans vegetation in the right atrium and superior vena cava was operated on successfully. During the newborn period he had had a right transverse colostomy for Hirschsprung's disease. Ten months later a subsequent rectosigmoidectomy and direct anastomosis were performed, but because of peritonitis that followed a leak at the site of the anastomosis parenteral nutrition was needed for 8 weeks. The probable source of Candida was an infected intravenous line.
