Chest roentgenography showed lung congestion and cardiomegaly, with a cardiothoracic ratio of 84%. Echocardiography revealed severe mitral and tricuspid regurgitation and pulmonary hypertension. Coronary angiography revealed a dilated RCA fistula draining into the coronary sinus, with a Qp\/Qs ratio of 2.3. Surgery was performed via median sternotomy. Under cardiac arrest, mitral valve replacement and tricuspid valve plasty were performed. The RCA was divided at the proximal portion, just distal to the origin of the conus branch. Through a longitudinal incision on RCA, the orifices of the posterior descending artery and the two major right ventricular branches were identified and trimmed as buttons. The dilated RCA was replaced with the saphenous vein graft, which was sequentially anastomosed with the buttons. Postoperative angiography showed visualization of the saphenous vein and right ventricular branches, with the elimination of the huge shunt flow from the RCA.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>Eliminating shunt flow, resecting the dilated portion of the RCA &amp;gt; 10\u2005mm in diameter, and recreating sufficient coronary perfusion to the right ventricle by replacement of RCA are crucial for favourable early and late clinical outcomes of diffusely aneurysmal coronary artery fistula.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytaf269","type":"journal-article","created":{"date-parts":[[2025,5,28]],"date-time":"2025-05-28T11:48:24Z","timestamp":1748432904000},"source":"Crossref","is-referenced-by-count":0,"title":["Replacement of aneurysmal right coronary artery with reconstruction of posterior descending and right ventricular branches in coronary artery fistula draining into the coronary sinus: a case report"],"prefix":"10.1093","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-7975-9841","authenticated-orcid":false,"given":"Yuya","family":"Yamazaki","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Surgery, Akita University Graduate School of Medicine , 1-1-1, Hondo Akita City, Akita 010-8543 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyuki","family":"Nakajima","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Akita University Graduate School of Medicine , 1-1-1, Hondo Akita City, Akita 010-8543 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Itaru","family":"Igarashi","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Akita University Graduate School of Medicine , 1-1-1, Hondo Akita City, Akita 010-8543 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takeshi","family":"Arai","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Akita University Graduate School of Medicine , 1-1-1, Hondo Akita City, Akita 010-8543 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daichi","family":"Takagi","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Akita University Graduate School of Medicine , 1-1-1, Hondo Akita City, Akita 010-8543 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,5,28]]},"reference":[{"key":"2025061007270773300_ytaf269-B1","doi-asserted-by":"crossref","first-page":"63","DOI":"10.1111\/j.1747-0803.2006.00012.x","article-title":"Solitary coronary artery fistulas: a congenital anomaly in children and adults.
