Considering these mechanisms and the increasing incidence of venous thrombosis with age, a higher prevalence of paradoxical embolism in ACHD patients with residual atrial shunts may be suspected. Regular follow-up of patients with ACHD remains important throughout life even in seemingly stable lesions.<\/jats:p>","DOI":"10.3389\/fcvm.2022.847244","type":"journal-article","created":{"date-parts":[[2022,3,16]],"date-time":"2022-03-16T06:08:03Z","timestamp":1647410883000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case
