Value of Coronary Angiography in the Cardiac Myxoma

Abstract

Preoperative coronary angiography for cardiac myxoma not only excludes coronary artery disease but also detects the artery feeding the cardiac myxoma, which has several clinical implications. In this study, we examined cardiac myxoma cases in two tertiary hospitals using coronary angiography to identify the artery feeding the myxoma. We retrospectively reviewed 42 patients with cardiac myxoma who had undergone surgical removal between July 2008 and December 2015 in two tertiary hospitals, and recorded their baseline characteristics, echocardiographic findings, and coronary angiography. Among those 42 patients, 23 (55%) had coronary angiography before surgery and in no case was significant luminal narrowing observed. In 21 of the coronary angiograms, the artery feeding the cardiac myxoma had a vascular branch (100%), clusters of tortuous vessels with contrast medium pooling (67%), an arteriocavity fistula (33%), and a mobile feeding artery (67%). No significant relationship was found between coronary artery dominance type and the origin of the artery feeding the cardiac myxoma (P = 0.362). Identification of the artery feeding the cardiac myxoma, with a distinctive vascular appearance in coronary angiography, is important for several clinical applications such as helping to diagnose cardiac myxoma and to plan the surgical approach.
