Dilated cardiomyopathy being the presenting manifestation of Takayasu arteritis and treated with renal angioplasty.

ABSTRACT

Dilated cardiomyopathy (DCM) is an uncommon complication of Takayasu arteritis (TA) with a prevalence of about 6%. We report a case of 14-year-old girl who presented with dyspnea, bipedal edema, loss of weight, and easy fatigability for three months. She was being treated for DCM for the same duration. Clinical examination revealed absence of both upper limb pulses. Echocardiography revealed features of DCM with severe biventricular dysfunction (ejection fraction 30%). Computed tomography angiogram confirmed the diagnosis of TA and revealed the presence of bilateral renal artery stenosis. Bilateral renal angioplasty was done, and immunosuppressant therapy with oral prednisolone and weekly oral methotrexate was started.
