A Surgically-treated Case of Left Atrial Myxoma Complicating Coronary Artery Fistula.

Abstract

SUMMARYA surgically-treated case of left atrial myxoma complicating congenital coronary artery fistula is reported. A review of the literature indicates that this complication has not been reported previously. (Jpn Heart J 36: 825-828, 1995) Key words:Cardiac myxoma Congenital coronary artery fistula Angiographically visible neovascularity Lake-like pooling C ORONARY artery fistula (CAF) has been considered to be a rare anomaly; its incidence was 0.17% in 126,595 patients undergoing coronary arteriography (CAG) during the period of 1960 to 1988.1) Recent advances in CAG and the more widespread adoption of this technique are reportedly related to the increased frequency of detection of CAF. The incidence of primary tumors of the heart in autopsy cases ranges from 0.0017 to 0.28%, and myxomas are the most common type of primary cardiac tumor, comprising 30 to 50% of the total in most studies.2) Recent progress in echocardiography is also linked to the easier diagnosis of myxoma. The prevalence of angiographically visible neovascularity in patients with myxoma is reported to be 40%.3) Our review of the literature, however, failed to uncover a single case of CAF complicated by cardiac myxoma. CASE REPORTA 51 year-old female was admitted to our hospital for the further evaluation of palpitations, dyspnea, and chest discomfort. She had noted these symptoms for the previous 6 years, but she had not received any medication. Because both the duration and frequency of the episodes had increased, she consulted our hospital in May 1988.

“…In literature a very small number of rare cases like this are reported. [1][2][3] In our case, the patient underwent cardiac surgery within 2 days with a complete removal of the 2 masses. The histopathological examination confirmed the diagnosis of 2 atrial myxomas widely vascularized.…”

Aneurysmal and Partially Thrombosed Orifice of a Coronary Artery Fistula into the Right Atrium Combined with Patent Foramen Ovale

“…atrial septum defects, patent ductus arteriosus, atresia of proximal right coronary artery or with cardiac tumors i.e. angiosarcoma (most frequent type of malignant tumors) have been reported [3,5,6]. Usually, these rare, mostly congenital malformations are minute and require no definitive therapy.…”
