Lymphocytic myocarditis presenting as nausea, vomiting, and hepatic dysfunction in the first trimester of pregnancy.

BACKGROUND

Lymphocytic myocarditis, an immune disorder of left ventricular dysfunction with sometimes confounding clinical presentations, occurs rarely during pregnancy.

CASE: At 12 weeks gestation, a multigravid patient presented with a 2-month history of nausea and vomiting. Other symptomatology included postprandial epigastric pain, loose stools, and a 10-lb (4.5-kg) weight loss. Laboratory evaluation revealed evidence of hepatic dysfunction with a coagulopathy and an absolute unconjugated hyperbilirubinemia. While undergoing evaluation, the patient deteriorated rapidly and suffered a cardiopulmonary arrest. Autopsy revealed a congested liver and spleen associated with a dilated cardiomyopathy and lymphocytic myocarditis.

CONCLUSION

Medically virulent disease processes can mimic the common pregnancy complaint of nausea and vomiting. Intrinsic cardiac disease with secondary hepatic compromise is a rare cause of gastrointestinal symptomatology early in pregnancy.
