摘　　要：BACKGROUND Valvular heart disease affects more than 100 million people worldwide and is associated with significant morbidity and mortality.The prevalence of at least moderate valvular heart disease is 2.5%across all age groups,but its prevalence increases with age.Mitral regurgitation and aortic stenosis are the most frequent types of valvular heart disease in the community and hospital context,res-pectively.Surgical valve replacement(or mitral valve repair)is the standard of care for treating heart valve disease.However,the replacement of a prosthetic heart valve can lead to complications,either in the peri-procedural phase or in the long-term follow-up period.CASE SUMMARY We present a case of a 71-year-old female patient with a history of mitral valve replacement and warfarin anti-coagulation therapy.She was admitted to the intensive care unit due to spontaneously reperfused ischemic stroke of probable cardioembolic etiology.A dysfunctional mitral prosthesis was identified due to malfunction of one of the fixed discs.Furthermore,a possible microthrombotic lesion was suspected.Therefore,systemic thrombolysis was performed with subsequent normalization of mitral disc opening and closing.CONCLUSION This case underscores the critical importance of a multidisciplinary approach for timely decision-making in critically ill patients with prosthetic valve complications.
