A Case of Right Ventricular Myocardial Fibroma and a Review of Reported Cases in Japan / 日本心臓血管外科学会雑誌

ABSTRACT

Cardiac fibromas are rare tumors. A 12-year-old girl who had no cardiac symptoms was evaluated because of her abnormal ECG. Physical examination revealed a grade 1/6 systolic murmur. Routine laboratory examination results and the chest X-ray films were normal. The ECG showed a negative T wave at leads II, III, aVF and V_3-4. Two-dimensional echocardiography demonstrated a tumor in the lower right ventricular free wall. Operation was performed on July 12, 1990. Sharp dissection was used to remove the tumor through right ventriculotomy. She had an uneventful postoperative course and is well 7 years later with no evidence of recurrence. Pathological findings including immunohistochemical studies revealed cardiac fibroma. The 22 reported cases of cardiac fibroma in Japan were reviewed.
