Acute peritonitis as the first presentation of valvular cardiomyopathy.

Valvular cardiomyopathy can present a diagnostic challenge in the absence of overt cardiac symptoms. This report describes the case of a 46-year-old woman who presented with acute peritonitis associated with vomiting and abdominal distension. Subsequent abdominal computed tomography and ultrasound revealed bibasal pleural effusions, ascites, and normal ovaries. An echocardiogram revealed that all cardiac chambers were dilated with a global decrease in contractility and severe mitral, tricuspid, and aortic regurgitation. A diagnosis of cardiomyopathy with acute heart failure, secondary to valvular heart disease, was secured. Acute peritonitis as the presenting feature of valvular cardiomyopathy is a rare clinical entity.
