Infracardiac total anomalous pulmonary venous drainage: a diagnostic challenge.

Infracardiac total anomalous pulmonary venous drainage can be erroneously diagnosed as respiratory distress of several different etiologies during the neonatal period. A cross-sectional echocardiography study with Doppler color flow mapping can preoperatively determine the precise drainage site and pulmonary venous return pattern, thereby allowing cardiac surgery to be performed promptly, prior to any clinical deterioration.

Left ventricular systolic function assessed by echocardiography in children and adolescents with osteosarcoma treated with doxorubicin alone or in combination with dexrazoxane.

Objective: To evaluate left ventricular (LV) systolic function by means of echocardiography in patients with osteosarcoma treated with doxorubicin alone or in combination with dexrazoxane.

Methods: The study analyzed 55 patients with osteosarcoma, with or without metastasis, undergoing a six-cycle chemotherapy regimen of doxorubicin, who were divided into two groups according to dexrazoxane use. Group I: Thirty-seven patients who did not receive dexrazoxane (28 males, average age 15.
