High-Output Heart Failure in Multiple Myeloma
Abstract
We introduce the innovative use of technetium-99m–labeled macroaggregated albumin to diagnose high-output heart failure in a patient with multiple myeloma with persistent congestion symptoms. Symptom resolution occurred with lenalidomide and steroids. This marks the first clinical use of technetium-99m–labeled macroaggregated albumin for clarifying high-output heart failure etiology.
