Surgically treated primary cardiac tumors in early infancy and childhood.

OBJECTIVE: Primary heart tumors in childhood are rare and mostly benign. Surgical treatment is advocated when symptoms or hemodynamic impairment is present. MATERIALS AND METHODS: Between 1986 and 2003, 8 children (3 males and 5 females, age ranging 5 days to 6.7 years, median 78 days) with a clinical diagnosis of cardiac mass were treated with surgery. Diagnosis was made by prenatal echocardiography in 3 patients and by 2-dimensional Doppler echocardiography in 5 patients. RESULTS: Complete surgical excision of the cardiac mass was feasible in all but 1 patient who underwent orthotopic heart transplantation. Surgical pathology examination revealed myxoma in 2 patients, fibroma in 2 patients, rhabdomyoma in 2 patients (multiple in 1), hamartoma in 1 patient, and teratoma in 1 patient. One patient died of cerebral malignancy 38 months after cardiac transplantation. At a mean follow-up of 69.2 months (range 3-190 months), all the remaining patients are asymptomatic, with good ventricular function on 2-dimensional echocardiography and no signs of residual or recurrent tumor. CONCLUSION: Surgical excision of obstructive cardiac tumors in childhood is safely feasible. Heart transplantation may represent the only therapeutic option when the tumor extensively invades the ventricular walls. Although 2-dimensional echocardiography remains a reliable diagnostic tool, a definite diagnosis of tumor histotype requires a thorough histopathologic characterization.

Cardiopulmonary anatomy and function in long-term survivors of mild to moderate congenital diaphragmatic hernia.

BACKGROUND/PURPOSE: In the last decades, several studies regarding cardiopulmonary sequelae in survivors of congenital diaphragmatic hernia (CDH) have been published, but results often are conflicting, and controversies still exist. The aim of this study was to assess cardiopulmonary anatomic and functional outcome in a group of long-term survivors of CDH of mild to moderate degree. METHODS: Twenty-four children aged 8.15 +/- 2.80 years underwent clinical examination with growth assessment, chest radiographs, echocardiography, pulmonary perfusion scintigraphy, static lung volumes measurement, and spirometry. RESULTS: Mean Z scores of weight for age and height for age were within normal values. Echocardiography showed normal anatomy and function in all but 3 patients with isolated CDH, in whom minor alterations were detected. Mean perfusion to the affected side was significantly lower (45.16 +/- 5.30%; P <.0001) but still within normal range. Four children showed a substantial impairment of perfusion to the hernia side. The mean spirometric values and pulmonary volumes were normal. However, a mild restrictive pattern was evident in 6 children (27.3%), an obstructive pattern in 3 (13.6%), and a mixed obstructive and restrictive impairment in 1. CONCLUSIONS: Hypoplastic lungs of mild to moderate CDH survivors continue to cause pulmonary morbidity in some children many years after the correction of the defect. In particular, lung perfusion appears to be impaired in 20% of the patients and pulmonary function in 45%, without any significant cardiac or developmental sequelae. The negative correlation between FEV1 and duration of ventilation at presentation (r = -0.49; P =.026) may be caused by the consequences of lung hypoplasia, but initial ventilatory management may contribute to increased pulmonary morbidity. Relationship between perfusion and FEF25-75 (r = 0.61; p = 0.004) could reflect an equivalent degree of reduction in the caliber of distal airways and pulmonary vascular tree.

Left atrial myxoma in a child: case report and review of the literature.

A left atrial mass in a 2.7-year-old girl who presented with congestive heart failure, which surgical pathology revealed to be a myxoma, is reported. The timely precise diagnosis obtained by means of two-dimensional echocardiography allowed the immediate surgical treatment of this rare, benign but potentially lethal cardiac tumor in infancy.
