Key result
Complete surgical removal of a huge biatrial myxoma successfully treated angina pectoris induced by a coronary steal effect from the tumor's extensive vascular lesions.
Why the study?
Angina pectoris can be the first manifestation of a large biatrial myxoma causing coronary steal effect, which is a rare clinical presentation.

Coronary steal should be considered in myxoma-related angina; leaves open the prevalence of this mechanism in biatrial tumors.
A 73-year-old woman with a history of atrial fibrillation suffered from exertional chest pain and discrete dyspnoea. Cardiac catherization showed a vascular malformation in the atria, fed from vessels of the circumflex and left descending coronary artery. Echocardiography detected a biatrial tumour (13.7 x 9.7 cm). The tumour mass was completely removed and histologic examination revealed a biatrial myxoma with extensive vascular lesions which apparently induced angina by coronary steal effect.

Alexiou et al. (2009) conducted a case report in Biatrial myxoma (n=1). Surgical removal of tumor mass was evaluated. Complete surgical removal of a huge biatrial myxoma successfully treated angina pectoris induced by a coronary steal effect from the tumor's extensive vascular lesions.
