An 80-year-old man presented with dyspnea and chest pain two decades after CABG (LIMA-LAD, SVG-RCA). Coronary angiography revealed SVG occlusion with contrast extravasation and mass formation adjacent to the right heart chambers. CT angiography confirmed a 39 mm mediastinal pseudoaneurysm from proximal SVG rupture, compressing the right heart chambers and lung, with consequent left ventricular dysfunction (EF 45%), elevated pulmonary pressures, and orthostatic hypotension. Following Heart Team discussion, the patient underwent successful pseudoaneurysm resection with right coronary artery revascularization using a left radial artery graft. Symptoms and cardiac function improved at one-month follow-up. This case highlights the importance of clinical suspicion for SVG pseudoaneurysm in patients with prior CABG, and the central role of CT angiography and multidisciplinary decision-making in management.<\/jats:p>","DOI":"10.21542\/gcsp.2026.17","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T23:14:32Z","timestamp":1777590872000},"source":"Crossref","is-referenced-by-count":0,"title":["Late saphenous vein graft rupture presenting as a compressive mediastinal pseudoaneurysm"],"prefix":"10.21542","volume":"2026","author":[{"given":"Dimitrios","family":"Afendoulis","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sotirios","family":"Tsalamandris","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Flora","family":"Tsakirian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nikolaos","family":"Tsiamis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Georgios","family":"Benetos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kostas","family":"Tsioufis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Konstantinos","family":"Toutouzas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"8990","published-online":{"date-parts":[[2026,4,30]]},"container-title":["Global Cardiology Science and Practice"],"original-title":[],"link":[{"URL":"https:\/\/globalcardiologyscienceandpractice.com\/index.php\/gcsp\/article\/download\/1060\/737","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/globalcardiologyscienceandpractice.com\/index.php\/gcsp\/article\/download\/1060\/737","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T23:14:32Z","timestamp":1777590872000},"score":1,"resource":{"primary":{"URL":"https:\/\/globalcardiologyscienceandpractice.com\/index.php\/gcsp\/article\/view\/1060"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,4,30]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2026,4,30]]}},"URL":"https:\/\/doi.org\/10.21542\/gcsp.2026.17","relation":{},"ISSN":["2305-7823"],"issn-type":[{"value":"2305-7823","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,4,30]]}}}
