A rare systemic etiology of heart failure and liver dysfunction.

Systemic amyloidosis is a rare condition that can manifest with cardiomyopathy, hepatic dysfunction, and renal disease. Diagnosis is often missed and/or delayed due to chronic multi-system involvement and indeterminate signs and symptoms. Treatment generally involves systemic therapy and autologous stem-cell transplantation.

Bacterial endocarditis presenting in an adult patient with undiagnosed double-chambered right ventricle.

Double-chambered right ventricle (DCRV) is a rare congenital heart defect often associated with ventricular septal defect and pulmonary stenosis. Cardiac catheterization or magnetic resonance imaging can differentiate between DCRV and Tetralogy of Fallot when echocardiogram is inconclusive. Patients are at an increased risk for bacterial endocarditis.
