In this report we describe an unusual presentation of retroperitoneal fibrosis and inferior vena cava (IVC) obstruction that was unidentified by noninvasive testing and ultimately diagnosed using exercise right heart catheterization and venography. Exercise hemodynamic catheterization revealed a high pressure gradient across the IVC obstruction during exercise that resulted in reduced preload and inappropriately low cardiac output reserve. The patient ultimately underwent angioplasty and stenting of the obstruction resulting in resolution of his symptoms. \u00a9 2013 Wiley Periodicals, Inc.<\/jats:p>","DOI":"10.1002\/ccd.25062","type":"journal-article","created":{"date-parts":[[2013,6,13]],"date-time":"2013-06-13T22:20:07Z","timestamp":1371162007000},"source":"Crossref","is-referenced-by-count":1,"title":["Exercise right heart catheterization for inferior vena cava obstruction: Confirming the hemodynamic significance of an anatomic lesion"],"prefix":"10.1002","volume":"83","author":[{"given":"Mackram F.","family":"Eleid","sequence":"first","affiliation":[{"name":"Division of Cardiovascular Diseases Mayo Clinic College of Medicine Rochester Minnesota"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haraldur","family":"Bjarnason","sequence":"additional","affiliation":[{"name":"Department of Radiology Mayo Clinic College of Medicine Rochester Minnesota"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert L.","family":"Frye","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Diseases Mayo Clinic College of Medicine Rochester Minnesota"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rick A.","family":"Nishimura","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Diseases Mayo Clinic College of Medicine Rochester Minnesota"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,7,16]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0b013e3181afc439"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0b013e3181afc420"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurjhf\/hft026"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.2169\/internalmedicine.51.7378"}],"container-title":["Catheterization and Cardiovascular Interventions"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fccd.25062","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.25062","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,6]],"date-time":"2023-10-06T04:52:29Z","timestamp":1696567949000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccd.25062"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,7,16]]},"references-count":4,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2014,1]]}},"alternative-id":["10.1002\/ccd.25062"],"URL":"https:\/\/doi.org\/10.1002\/ccd.25062","archive":["Portico"],"relation":{},"ISSN":["1522-1946","1522-726X"],"issn-type":[{"value":"1522-1946","type":"print"},{"value":"1522-726X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,7,16]]}}}
