CD73 plays a protective role against aortic valve calcification; therefore, its deletion results in aortic valve calcification. However, to date, there are no reports of a patient with CALJA with aortic stenosis. In this study, we describe 2 extremely rare cases of sisters with identical NT5E gene mutation patterns, both of whom developed late-onset severe aortic stenosis and limb ischaemia. Both patients underwent aortic valve replacement and bilateral distal arterial bypass surgeries successfully. They were genetically diagnosed with CALJA based on the NT5E mutation. Our report suggests that NT5E mutations should be considered in patients requiring aortic valve replacement for a calcified aortic valve and bypass surgery for specific calcified and occluded arteries.<\/jats:p>","DOI":"10.1093\/icvts\/ivab229","type":"journal-article","created":{"date-parts":[[2021,7,31]],"date-time":"2021-07-31T19:09:10Z","timestamp":1627758550000},"page":"45-48","source":"Crossref","is-referenced-by-count":3,"title":["NT5E
