Transthoracic echocardiography revealed severe right\u2010sided cardiac enlargement and a heterogeneous right atrial intracavitary mass (3.2 \u00d7 3.1 cm) suspected to arise from the heart base, with tricuspid regurgitation (maximal velocity 4.03 m\/s). Abdominal ultrasonography showed hepatic venous congestion and marked ascites; fluid was a modified transudate. Medical therapy failed to resolve ascites, and surgical debulking was performed on Day 7 under partial cardiopulmonary bypass. The mass was firmly adherent to the atrial septal aspect and could not be completely excised. Postoperatively, ascites and clinical signs resolved, right\u2010sided cardiac enlargement decreased, and tricuspid regurgitation was no longer detectable; the dog was discharged on Day 14. A recurrent right atrial mass was documented on Day 360 without recurrence of right\u2010sided heart failure. The dog died on Day 390 from pancreatitis\u2010associated biliary obstruction and multiple organ failure. Necropsy confirmed an aortic body tumour with intracardiac extension into the right atrium and pulmonary metastasis with tumour emboli.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Partial cardiopulmonary bypass\u2010assisted palliative debulking may temporarily relieve life\u2010limiting intracardiac obstruction in carefully selected dogs; however, this approach is high\u2010risk and non\u2010curative, and its contribution to long\u2010term survival remains uncertain because postoperative toceranib therapy and the natural behaviour of the tumour may also have influenced the clinical course.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/vms3.71244","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T23:06:51Z","timestamp":1790204811000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Palliative Debulking of an Aortic Body Tumour With Right Atrial Invasion in a Dog Under Partial Cardiopulmonary Bypass"],"prefix":"10.1002","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3924-0215","authenticated-orcid":false,"given":"Shuji","family":"Suzuki","sequence":"first","affiliation":[{"name":"Laboratory of Veterinary Surgery Nippon Veterinary and Life Science University  Musashino Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1207-8644","authenticated-orcid":false,"given":"Sachiyo","family":"Tanaka","sequence":"additional","affiliation":[{"name":"Laboratory of Veterinary Surgery Nippon Veterinary and Life Science University  Musashino Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3112-1003","authenticated-orcid":false,"given":"Nobuo","family":"Kanno","sequence":"additional","affiliation":[{"name":"Laboratory of Veterinary Surgery Nippon Veterinary and Life Science University  Musashino Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-5212-3221","authenticated-orcid":false,"given":"Takuya","family":"Yogo","sequence":"additional","affiliation":[{"name":"Laboratory of Veterinary Surgery Nippon Veterinary and Life Science University  Musashino Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0691-4316","authenticated-orcid":false,"given":"Yasuji","family":"Harada","sequence":"additional","affiliation":[{"name":"Laboratory of Veterinary Surgery Nippon Veterinary and Life Science University  Musashino Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0353-3668","authenticated-orcid":false,"given":"Masaki","family":"Michishita","sequence":"additional","affiliation":[{"name":"Laboratory of Veterinary Pathology Nippon Veterinary and Life Science University  Musashino Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4474-4389","authenticated-orcid":false,"given":"Yasushi","family":"Hara","sequence":"additional","affiliation":[{"name":"Laboratory of Veterinary Surgery Nippon Veterinary and Life Science University  Musashino Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,23]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1939\u20101676.1998.tb02104.x"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1292\/jvms.60.1251"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.3389\/fvets.2021.635057"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/10406387241304438"},{"issue":"3","key":"e_1_2_11_6_1","first-page":"171","article-title":"Echocardiographic Results and Clinical Considerations in Dogs With Right Atrial\/Auricular Masses","volume":"33","author":"Fruchter A.
