Takayasu arteritis is a rare disease. Coronary involvement may appear in patients with Takayasu arteritis. With delayed diagnosis and the difficulty of treatment, Takayasu arteritis patients complicated with coronary abnormalities usually have poor prognosis. We present a rare case of acute left heart failure caused by total occlusion of the left main coronary artery due to Takayasu arteritis. A 30-year-old Chinese woman presented at our hospital with recurrent chest tightness accompanied by dyspnoea. A series of modern imaging methods were used for diagnosis and evaluation of Takayasu arteritis, including invasive angiography, CT angiography, and vascular ultrasound. The patient received drugs therapy including glucocorticoids, immunosuppressants, and cardiovascular drugs, without a reperfusion therapy. Cardiac events, inflammatory marks, and cardiac function were observed during 2-year follow-up period. In this paper, we briefly disscuss the diagnosis and treatment for young women with cardiac complication caused by Takayasu arteritis.

This report describes a rare case of left main coronary artery occlusion caused by embolisation of an intra-cardiac tumour in an 11-year-old patient. The patient presented with severe chest pain with ST-segment depression in the inferolateral leads with evidence of decreased left ventricular function, anterior-apical hypokinesis, and a pedunculated mass attached to the mitral valve. An urgent cardiac catheterisation was performed, which revealed near-complete obstruction of the left anterior descending coronary artery. Transcatheter aspiration of the embolic material was successfully performed. The final pathological examination revealed an inflammatory myofibroblastic tumour, which is a rare benign tumour, characterised by the proliferation of myofibroblasts and inflammatory cell infiltration.
