Ventricular tumors: surgical options

Primary cardiac tumors of the ventricles are very uncommon. During an 8-year period only, nine such patients were encountered: the tumor was primarily in the right ventricle in six, in the left ventricle in two and biventricular in one. There were seven children and two adults in this series. Histologically, the neoplasm was benign in all patients. The tumor was obstructive in six patients, five of whom underwent surgery (complete resection in three, partial excision in one and a Fontan-Kreutzer procedure in one); one neonate died before an operation could be performed. In addition, one patient with an epicardial tumor underwent complete resection. There were no early or late deaths among the six patients treated surgically. The tumor was small and non-obstructive in two patients, who were not operated on: one died suddenly, and the other was followed without intervention. In summary, complete or partial excision of ventricular neoplasms can usually be accomplished with good long-term results. If resection is not possible, effective palliation may be achieved with a Fontan-type operation, excluding the right ventricle from the circulation.
