Key result
Spontaneous anastomosis between the right internal mammary and right coronary arteries following coronary occlusion provided sufficient perfusion to preserve inferior wall myocardial function.
This case demonstrates that spontaneous anastomosis can develop between the internal mammary and coronary arteries following coronary occlusion, potentially preserving myocardial function.
An unusual case of spontaneous development of anastomosis between the right internal mammary artery and right coronary artery was discovered by internal mammary arteriography. This appeared to have been promoted by coronary occlusion. Perfusion was sufficient to preserve myocardial function of the inferior wall.
