Treating the elderly is often problematic, especially when congenital heart disease is diagnosed. The aim of this study is to present the case of a 72-year old woman with depression syndrome, paroxysmal atrial fibrillation and past cerebral stroke, in whom persistent ductus arteriosus Botalli was diagnosed. Due to exacerbation of the depressive syndrome, she did not give her consent to further diagnostics, possible interventional procedures and treatment with oral anticoagulants. After intermission of the therapy she was treated with dabigatran. The patient is still undergoing outpatient treatment and so far, no cerebrovascular episodes have been recorded.
