All patients presented to our hospital for evaluation because of worsening functional class, dyspnoea, or syncope. During tomographic planning, the aortic annulus was measured at the level of the deepest sinus for the selection of the number of devices. Due to the presence of four cusps, the smallest cusp was excluded, and three sinuses were virtualized for placement of the pigtail catheter during the procedure. Without complications, a 23\u2005mm Edwards SAPIEN 3 was deployed through the femoral artery in both patients. Control aortography showed no valve leakage or regurgitation.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>In patients with QAV and aortic stenosis undergoing TAVR, similar to the tricuspid valve, tomographic planning can be used to ensure the success of the procedure. However, unlike the tricuspid valve, where the selection of the device number is based on the measurements of the aortic annulus at the level of the non-coronary sinus, in these QAV cases, we perform the measurements at the level of the deepest aortic sinus (right coronary sinus).<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytae079","type":"journal-article","created":{"date-parts":[[2024,2,8]],"date-time":"2024-02-08T21:33:48Z","timestamp":1707428028000},"source":"Crossref","is-referenced-by-count":4,"title":["Transcatheter aortic valve replacement planning with cardiac computed tomography in quadricuspid aortic valve stenosis: a case series"],"prefix":"10.1093","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1600-9152","authenticated-orcid":false,"given":"Heberto","family":"Aquino-Bruno","sequence":"first","affiliation":[{"name":"Interventional Cardiology Service, Centro Medico Nacional 20 de Noviembre , Av.
