  • Title: The diagnosis and clinical importance of tumour neovascularisation from coronary artery to right atrial myxoma.
    Author: Acikel S, Bozkaya O, Kiziltepe U.
    Journal: Kardiol Pol; 2012; 70(5):501-4. PubMed ID: 22623246.
    Abstract:
    Myxomas are the commonest cardiac tumours and are usually localised in the atria. Neovascularisation in cardiac myxomas has been shown in previous case reports. However, the clinical importance of neovascularisation in cardiac myxomas is not well understood. In our case report, we present a right atrial myxoma in a 46 year-old woman admitted to our hospital with exertional angina and dyspnea. Coronary angiography revealed the presence of tumour neovascularisation from the right coronary artery, with no evidence of coronary artery stenosis. We thus speculate that neovascularisation of myxoma may cause typical anginal symptoms as a result of coronary steal phenomenon. Coronary angiography might help in the evaluation of the neovascularisation process and also in indicating surgery.
