s Primary Cardiac Tumors: A Retrospective Study

Objectives: Primary cardiac tumors are rare and account for 0.001 to 0.03% of cardiac lesions. The authors aim to describe the clinical, the microscopic and the therapeutic characteristics of these tumors through a 13-year-experience in order to highlight the diagnostic challenges faced. Methods: We report 10 primary cardiac tumors diagnosed in the Departments of Pathology and Thoracic Surgery of the same hospital through a 13-year-period. Results: Our study was conducted on 7 women and 3 men. The mean age of the patients was 54.22 years (average, 12 to 79 years). Dyspnea represented the most frequent symptom. Physical examination was normal in all patients. Trans-thoracic ultra-sound examination was performed in all patients. Cardiac MRI allowed localizing the tumors in 2 patients. They were located into the left auricle (6 cases), the right auricle (1 case) and the pericardium (3 cases). The microscopic examination was concluded to myxoma (7 cases), haemangioma (2 cases) and hemangioendothelioma (1 case). Surgical resection was possible in 9 patients. It was impossible in the case of hemangioendothelioma because of the adherence. One death was recorded secondary to postoperative arrhythmia. The other patients presented no complications after a follow-up period ranging from 2 months to 5 years. Conclusion: Cardiac tumors are challenging in their diagnosis and management. A positive diagnosis is based on microscopic examination. Surgical treatment plays a key role and is possible in the majority of benign tumors. The prognosis of malignant tumors remains poor even if a complete surgical resection is possible.
