Supravalvular mitral ring in a patient with Turner syndrome: A case report

Turner syndrome is a relatively common genetic disorder of female development characterized by partial or complete absence of an X chromosome. Some of the patients may present with cardiovascular abnormalities. However, there is no case with Turner syndrome with a supravalvular mitral ring (SMR) in the literature. Herein, we present a case of SMR accompanied by Turner syndrome who presented with progressive shortness of breath and exertional dyspnea, that was successfully treated.
