Factitious insufficiency may result from faulty catheter placement or from ventricular extrasystoles caused by the pressure injection of the contrast agent. False negative results are almost nonexistent, and if no insufficiency is seen on a technically adequate angiocardiogram, the valve can be considered to be competent.<\/jats:p>","DOI":"10.1161\/01.cir.43.4.599","type":"journal-article","created":{"date-parts":[[2012,6,11]],"date-time":"2012-06-11T23:56:43Z","timestamp":1339459003000},"page":"599-605","update-policy":"http:\/\/dx.doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":38,"title":["Angiocardiographic Evaluation of Valvular Insufficiency"],"prefix":"10.1161","volume":"43","author":[{"given":"MURRAY G.","family":"BARON","sequence":"first","affiliation":[{"name":"From the Department of Radiology of The Mount Sinai School of Medicine of the City University of New York and The Mount Sinai Hospital, New York, New York 10029."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","container-title":["Circulation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ahajournals.org\/doi\/pdf\/10.1161\/01.CIR.43.4.599","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,12]],"date-time":"2024-05-12T14:03:16Z","timestamp":1715522596000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ahajournals.org\/doi\/10.1161\/01.CIR.43.4.599"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1971,4]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1971,4]]}},"alternative-id":["10.1161\/01.CIR.43.4.599"],"URL":"https:\/\/doi.org\/10.1161\/01.cir.43.4.599","relation":{},"ISSN":["0009-7322","1524-4539"],"issn-type":[{"value":"0009-7322","type":"print"},{"value":"1524-4539","type":"electronic"}],"subject":[],"published":{"date-parts":[[1971,4]]},"assertion":[{"value":"1971-04-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
