Transthoracic echocardiography revealed a large heterogeneous RVOT mass (3.1 \u00d7 2.0\u2005cm) with preserved left ventricular systolic function (LVEF 50\u201355%) and no significant obstruction (peak gradient 16\u2005mmHg). Transoesophageal and three-dimensional echocardiography demonstrated a sessile, non-pedunculated lesion with broad-based attachment. Cardiac magnetic resonance imaging showed an infiltrative mass with heterogeneous late gadolinium enhancement, with imaging features highly suggestive of metastatic involvement. A catheter-associated thrombus served as an internal comparator. The patient remained asymptomatic and proceeded to systemic therapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>This case illustrates an uncommon pattern of probable metastatic cardiac involvement presenting as a right-sided cardiac mass involving the RVOT and right ventricular free wall, detected incidentally in an asymptomatic patient. It further shows that baseline cardio-oncology imaging, performed for pre-treatment cardiovascular assessment, may incidentally identify clinically relevant structural abnormalities. Multimodality imaging supported characterization of the lesion and helped guide management.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytag438","type":"journal-article","created":{"date-parts":[[2026,7,16]],"date-time":"2026-07-16T11:49:16Z","timestamp":1784202556000},"source":"Crossref","is-referenced-by-count":0,"title":["Incidental detection of a probable metastatic right ventricular outflow tract mass with right ventricular free wall involvement from gastric adenocarcinoma: a multimodality imaging case report"],"prefix":"10.1093","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9814-0620","authenticated-orcid":false,"given":"Dorsa","family":"Shirini","sequence":"first","affiliation":[{"name":"Cardio-Oncology Department, Rajaie Cardiovascular Medical & Research Center, Hashemi Rafsanjani Expy , District 3, Tehran 1996911151 ,","place":["Iran"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4244-3937","authenticated-orcid":false,"given":"Haniyeh Faraji","family":"Azad","sequence":"additional","affiliation":[{"name":"Cardio-Oncology Department, Rajaie Cardiovascular Medical & Research Center, Hashemi Rafsanjani Expy , District 3, Tehran 1996911151 ,","place":["Iran"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mah Hedayati","family":"Emami","sequence":"additional","affiliation":[{"name":"Cardio-Oncology Department, Rajaie Cardiovascular Medical & Research Center, Hashemi Rafsanjani Expy , District 3, Tehran 1996911151 ,","place":["Iran"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8550-1378","authenticated-orcid":false,"given":"Azin","family":"Alizadehasl","sequence":"additional","affiliation":[{"name":"Cardio-Oncology Department, Rajaie Cardiovascular Medical & Research Center, Hashemi Rafsanjani Expy , District 3, Tehran 1996911151 ,","place":["Iran"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,7,20]]},"reference":[{"key":"2026072001563036500_ytag438-B1","first-page":"209","article-title":"Global cancer statistics 2020: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries","volume":"71","author":"Sung","year":"2021","journal-title":"CA A Cancer J Clinicians"},{"key":"2026072001563036500_ytag438-B2","article-title":"Prognostic implications of organ-specific metastases in advanced gastric cancer: a retrospective observational analysis of the SEER database","volume":"104","author":"Liu","year":"2025","journal-title":"Medicine (Baltimore)"},{"key":"2026072001563036500_ytag438-B3","doi-asserted-by":"crossref","first-page":"2079","DOI":"10.21037\/jgo-24-738","article-title":"Metastasis patterns and prognosis in patients with gastric cancer: a surveillance, epidemiology, and end results-based analysis","volume":"15","author":"Dong","year":"2024","journal-title":"J Gastrointest Oncol"},{"key":"2026072001563036500_ytag438-B4","doi-asserted-by":"crossref","first-page":"445","DOI":"10.1016\/j.amjsurg.2022.01.024","article-title":"Patterns of gastric cancer metastasis in the United States","volume":"224","author":"Sirody","year":"2022","journal-title":"Am J Surg"},{"key":"2026072001563036500_ytag438-B5","doi-asserted-by":"crossref","first-page":"27","DOI":"10.1136\/jcp.2005.035105","article-title":"Cardiac metastases","volume":"60","author":"Bussani","year":"2007","journal-title":"J Clin Pathol"},{"key":"2026072001563036500_ytag438-B6","doi-asserted-by":"crossref","DOI":"10.3390\/life15020291","article-title":"Cardiac metastasis: epidemiology, pathophysiology, and clinical management","volume":"15","author":"Luc\u00e0","year":"2025","journal-title":"Life"},{"key":"2026072001563036500_ytag438-B7","doi-asserted-by":"crossref","first-page":"1790","DOI":"10.1161\/CIRCULATIONAHA.112.000790","article-title":"Tumors metastatic to the heart","volume":"128","author":"Goldberg","year":"2013","journal-title":"Circulation"},{"key":"2026072001563036500_ytag438-B8","first-page":"1027","article-title":"Tumors of the heart.
