Background: Takayasu arteritis is a rare, systemic, inflammatory large vessel arteritis of unknown aetiology. It predominantly involves the aorta and its major branch arteries. It commonly occurs in women younger than 50 years of age. It can affect the cardiovascular system and renovascular hypertension and aortic regurgitation are the most prevalent manifestations. Dilated cardiomyopathy is rare and commonly due to renal artery stenosis or coronary artery involvement, otherwise, it is extremely rare.

Case Presentation: We are reporting a case of a 37-year-old woman presenting to the Emergency Department with acute stage IV NYHA dyspnea and orthopnea. Symptoms and signs were suggestive of acute decompensated heart failure which was managed medically using IV furosemide and nitrates. Transthoracic echocardiogram revealed a dilated cardiomyopathy, LVEF at 28%. Coronary artery angiography showed a distal chronic complete obstruction of left anterior descending artery with a subocclusion of the origin of the first diagonal artery, lesions which are not explaining the cardiomyopathy. Duplex ultrasound did not find any renal artery stenosis but a severe left post-vertebral subclavian artery stenosis. Laboratory tests are showing increased inflammation, no arguments for connective tissue disease. Takayasu arteritis was confirmed using the American College of Rheumatology criteria and patient was prescribed corticosteroids and cyclophosphamide along with heart failure therapy. This attitude improved her symptoms and quality of life as well as survival.

Conclusion: It is important for cardiologists to think of Takayasu arteritis as a potential cause of non-ischemic dilated cardiomyopathy, especially in a young woman, as immunosuppressive therapy can improve symptoms and LV remodeling, prevent LV systolic function deterioration and reduce cardiovascular events.
