C76. Primary Cardiac Tumors : Benign or Malignant ? The Importance of Clinicopathologic Confirmation : a case series

Cardiac tumor is a rare condition of space-occupying lesion mass in cardiac chamber. The incidence of clinically diagnosed Primary Cardiac Tumors is approximately 1,380/100 million individuals. Majority of cases are benign, with nearly half of them are cardiac myxoma. Although early clinical symptom of benign and malignant cardiac tumor are similar, the management and prognosis are much different.

To present serial cases of benign and malignant primary cardiac tumor.

Mrs. RH, a 60-year-old woman referred to heart failure clinic National Cardiovascular Center Harapan Kita with chief complaint of short of breath on exercise. Echocardiography confirmed a huge mass obstructed her left atrium. She was hospitalized urgently with giant Left Atrial Myxoma with normal coronary artery, then underwent surgery of LA myxoma extirpation, Mitral Valve repair and Tricuspid Valve repair. Histopathological analysis confirmed of LA myxoma.

Mr. RBM, a 42-years-old man came to emergency unit at National Cardiovascular Center Harapan Kita with chief complaint shortness of breath and palpitation in about 1 month. A history of a cardiac tumor extirpation and mitral valve replacement was done in Penang Adventist hospital 10 months before. Transthoracal and transesophageal echocardiography found solid mass obstructing mechanical valve. Histopathology analysis showed undifferentiated cardiac sarcoma and against LA myxoma.

Clinical course and management of cardiac tumor depends on early detection and histopathologic analysis. Although surgery is the cornerstone for cardiac tumor management, but confirmation of histopathologic findings is important.
