Primary and secondary cardiac tumors: clinical presentation, diagnosis, surgical treatment, and results

Abstract

Cardiac tumours are some of the rarest primary tumours, while cardiac metastasis are more common yet still relatively rare. Seventy five percent of primary cardiac tumours are benign tumours. Cardiac tumours present with a range of obstructive, embolic, arrhythmic or systemic symptoms, and in many cases may present asymptomatically. The clinical presentation depends largely on the size and location of the mass. With advances in cardiac imagining and the introduction of cardiopulmonary bypass, the diagnosis and surgical treatment of these rare tumours has improved the prognosis and outlook for benign and malignant tumours. Management depends on tumour histology, size and location as well as the clinical presentation. Conservative management is reserved for small, benign tumours that can undergo regular echocardiographic follow-up. Symptomatic benign tumours are treated with surgical resection and the results are excellent. Malignant primary cardiac tumours have a poor prognosis with high rates of relapse and a median survival of 10-24 months.
