Introduction:

Cardiac tumors are uncommon in the pediatric age group, most are primary and benign (90%), the most frequent being rhabdomyomas, fibroids and myxomas. Indications for surgical treatment are related to the hemodynamic or mechanical effect, arrhythmias and / or ventricular dysfunction they cause, rather than their pathological origin, benignity or tumor size. In malignant or metastatic tumors, the treatment is determined by the primary origin of the tumor, as well as the patient’s staging.

Objectives:

To present the types of tumors and management of patients with cardiac tumors who underwent surgical excision, as well as the short and medium-term outcomes.

Material and Methods:

This was a retrospective and observational study, performed by reviewing data from the medical records of children diagnosed with cardiac tumors by transthoracic echocardiography.

Results:

In our series, 4 of the 5 tumors were benign (80%) and 1 malignant (20%); there was 100% coincidence of the finding by two-dimensional transthoracic echocardiography of tumor mass image with the surgical findings; Histopathological diagnosis reported myxoma in 3 cases (60%), 1 patient (20%) had a Giant rhabdomyoma and 1 patient (20%) had a Thymus Mucoepidermoid Carcionoma. We found a positive correlation between clinical/imaging diagnosis and histopathological results.

Discussion:

The benign primary cardiac tumors in this series were referred for surgical excision based on their location and obstructive hemodynamic repercussions related to the ventricular entry pathways. In the case of the thymus mucoepidermoid carcinoma with a low degree of malignancy, the diagnosis and early surgical resection allowed total excision; it did not require additional therapy. Postoperative courses were without complications except for one case (20%) that required assistance with ECMO. All were discharged and remain asymptomatic and without tumor regression at 5 years, in the first case and 18 in the last. Two-dimensional transthoracic echocardiography continues to be the diagnostic method of choice for these cases.
