Diffuse alveolar hemorrhage and intravascular hemolysis due to acute mitral valve regurgitation


Diffuse alveolar hemorrhage (DAH) is a life-threatening condition that complicates various clinical entities. While mitral stenosis is a well-known cardiovascular cause, acute mitral regurgitation (MR) related DAH is rarely reported. We report a patient with a stormy course of acute MR induced DAH with concomitant Coomb’s negative intravascular hemolysis, which resolved completely after mitral valve surgical repair.
