Atypical vessels in the interatrial septum observed on coronary angiography may represent an early, subtle sign of a developing intracardiac myxoma.
Answers are grounded in this paper and cite their sources.
Atypical septal vessels may precede myxoma; hypothesis-generating and should not change practice without prospective validation.
We report on a woman with previously unknown left atrial myxoma, who underwent percutaneous coronary intervention. 45 months after the initial coronary angiography, echocardiography demonstrated a large atrial myxoma, which was not seen echocardiographically before. The retrospective analysis of the pre-intervention coronary angiography revealed atypical vessels in the atrial septum, which are interpreted as early signs of myxoma.
