[Cardiac tumors in children and adults: A Multicentric retrospective study]. / Comportamiento clínico de los tumores cardíacos desde el feto hasta el adulto: serie multicéntrica de 38 pacientes.

BACKGROUND: Cardiac tumors are very uncommon at all ages. There are important clinical differences between children and adults in the behavior of these tumors. AIM: To compare the behavior of primary and secondary cardiac tumors, from fetal age to adults. PATIENTS AND METHOD: Multicentric retrospective analysis of 38 children and adults with cardiac tumors, evaluated with echocardiography between January 1995 and August 2001. Medical records, echocardiographic and radiological examinations, surgical protocols and pathologic examinations were reviewed. Follow-up was obtained through data on medical records or calling patients by telephone. RESULTS: Tumors were diagnosed in 38 patients (13 children and 25 adults), from a total of 31.800 echocardiograms. In children the diagnosis was made by fetal, transthoracic or transesophageal echocardiography in 23.6% and 8% of cases, respectively. Eighty five percent were primary (10 benign and 1 malignant) and 15%, secondary tumors. Fifty four percent were rhabdomyomas and 75% regressed spontaneously. Seventy seven percent were symptomatic and 31% were treated with surgery. During a follow up of 44+/-35 months, 31% of patients died. In adults, 76% of tumors were diagnosed by transthoracic and 20% by transesophageal echocardiography. Seventy six percent were primary (18 benign and 1 malignant) and 24% secondary tumors. Fifty six percent were myxomas. Ninety two percent were symptomatic and 84% were treated surgically. Twenty percent of patients died in the early postoperative period. No adult patients had a follow-up. CONCLUSIONS: Rhabdomyomas were solely found in children. In adults, myxomas are the predominant cardiac tumors. Primary and metastasic malignant tumors are observed both in children and in adults.

Cirugía paliativa mediante operación de Norwood en distintas formas de corazón univentricular: resultados quirúrgicos inmediatos / Immediate results of palliative surgery for different forms of univentricular heart using the Norwood procedure

Background: Norwood procedure is used as the first stage in the palliative treatment of the hypoplastic heart syndrome and can be used, with some technical modifications, in other forms of univentricular heart with aortic stenosis or hypoplasia. These patients have a high mortality (50 percent), derived from the procedure itself and from their abnormal physiological status. Aim: To report our experience with the Norwood procedure. Patients and methods: Retrospective analysis of all patients subjected to the Norwood procedure between February 2000 and June 2003. Results: Thirteen patients (9 females, age range 5-60 days and median weight of 3.3 kg) were operated. Eight had hypoplastic heart syndrome and five had a single ventricle with aortic arch hypoplasia. The diagnosis was done in utero in eight patients. All technical variations, according to the disposition and anatomy of the great vessels, are described. Cardiac arrest with profound hypothermia was used in all and regional cerebral perfusion was used in nine. Three patients died in the perioperative period and three died in the follow up (two, four and 10 months after the procedure). Gleen and Fontan procedures were completed in five and one patients, respectively. Conclusions: Our results with the Norwood procedure are similar to other series. There is an important mortality in the immediate operative period and prior to the Glenn procedure (Rev MÚd Chile 2004; 132: 556-63).
