BackgroundHemolytic anemia after mitral valve repair is still an underestimated complication because it is a rare condition and there are few described case reports in the literature. The mechanism responsible for hemolysis most commonly involves a regurgitant jet and it appears to be independent of its severity as assessed by echocardiography. Patients may experience severe symptoms with only moderate regurgitant jets.Case presentationWe present a case of a 74-year-old Caucasian female who developed severe hemolytic anemia and decompensated heart failure due to a moderate mitral valve regurgitation jet, but it was not considered severe enough to explain such hemolysis. After exclusion of other causes of hemolytic anemia and the lack of clinical and laboratory improvement, the patient underwent valve replacement with a mechanical valve. Anemia and heart failure symptoms gradually resolved after surgery.ConclusionThis case report indicates the importance of including the diagnosis of hemolytic anemia after mitral valve repair in patients with severe hemolysis and a surgical history of heart surgery, even if echocardiography underestimates or is unclear for showing significant alterations. The interest on mitral valve repair as suggested by the increase in the number of these procedures performed worldwide, raises the possibility that hemolytic anemia could be probably seen more frequently in the future and be a cause of major concern, especially for cardiac surgeons.
International Journal of Case Reports and Images (IJCRI) is an international, peer reviewed, monthly, open access, online journal, publishing high-quality, articles in all areas of basic medical sciences and clinical specialties.Aim of IJCRI is to encourage the publication of new information by providing a platform for reporting of unique, unusual and rare cases which enhance understanding of disease process, its diagnosis, management and clinico-pathologic correlations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
