Moderate Mitral Regurgitation Secondary to Hammock Congenital Mitral Valve Disease

Abstract

A 30-year-old woman with a history of systemic lupus erythematosus and hypothyroidism . She started with dyspnea on moderate exertion, orthopnea, and a sensation of palpitations an early systolic murmur of mitral regurgitation was found. Transthoracic and transesophageal echocardiography reported hammock congenital mitral valve disease as a cause of mitral regurgitation with impaired functional class, requiring surgical valve replacement. The mitral arcade, or hammock mitral valve, is a very rare entity, even more so in the adult population, with a reported prevalence of 0.5%. It is characterized by abnormal papillary muscles connected directly to the anterior mitral.
