One month later, the patient developed acute heart failure. As the progression of anaemia due to renal anaemia seemed to cause acute heart failure exacerbation, we started an oral hypoxia-inducible factor prolyl hydroxylase (HIF-PH) inhibitor. After 2 weeks, the patient redeveloped shortness of breath. Transthoracic echocardiography revealed that the mean aortic valve pressure gradient (\u0394P) increased from 9 to 54\u2005mmHg, and the aortic valve area decreased from 1.93 to 0.86\u2005cm2. Blood work revealed a markedly elevated haemoglobin level from 8.0 to 13.2\u2005g\/dL, and transoesophageal echocardiography revealed markedly decreased left coronary and non-coronary cusp mobility. We diagnosed that the rapid increase in the haemoglobin level caused by the HIF-PH inhibitor was related to valve thrombosis and bioprosthetic dysfunction of the transcatheter aortic valve. The HIF-PH inhibitor was discontinued, and anticoagulation therapy was started. Transthoracic echocardiography at 16 days later revealed that the mean aortic valve \u0394P improved by 15\u2005mmHg, and the subjective symptoms resolved.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>This is the first report on a successful treatment of TAVR thrombosis formation associated with HIF-PH inhibitor use.
