Hypoproteinemia caused by tricuspid regurgitation: report of a case.
A case of tricuspid regurgitation (TR) complicated by severe hypoproteinemia is presented herein. A 68-year-old man who had undergone coronary artery bypass grafting (CABG) for postinfarction angina suffered repeated inferior myocardial infarction due to obstruction of the proximal right coronary artery, 3 years after which he developed systemic edema. Investigations revealed TR associated with hypoproteinemia; however, treatment consisting of aggressive diuretic therapy and albumin administration proved ineffective. The hypoproteinemia manifested as protein-losing enteropathy clinically, and the tricuspid valve was replaced to eliminate high venous pressure. The serum protein levels became normalized after the operation. Although TR is generally well tolerated in the absence of pulmonary hypertension, surgical management is recommended for patients with severe protein deficiency resistant to medical treatment.
