The occurrence of coronary artery aneurysms alongside these fistulas is even rarer, and they are associated with risks, including aneurysmal rupture, clot formation, and endocarditis. This report highlights a unique case of a five-chambered heart, where the right coronary artery anomalously drains into the interventricular septum, forming an additional fifth chamber. We demonstrated a complex aneurysmal CCF, which was initially masqueraded by a coexisting atrial septal defect (ASD). The report describes the diagnostic challenges and a successful transcatheter closure of this complex fistula, while also addressing the associated ASD.<\/jats:p>","DOI":"10.4103\/apc.apc_169_25","type":"journal-article","created":{"date-parts":[[2026,1,6]],"date-time":"2026-01-06T18:00:40Z","timestamp":1767722440000},"page":"509-512","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Transcatheter management of a complex aneurysmal coronary cameral fistula mimicking as five-chambered heart"],"prefix":"10.4103","volume":"18","author":[{"given":"Saurabhi","family":"Das","sequence":"first","affiliation":[{"name":"Department of Pediatric Cardiology, Health City Hospital, Guwahati, Assam, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shantanu","family":"Jain","sequence":"additional","affiliation":[{"name":"Department of Pediatric Cardiology, Health City Hospital, Guwahati, Assam, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pavel","family":"Barman","sequence":"additional","affiliation":[{"name":"Department of Radiology, Health City Hospital, Guwahati, Assam, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gaurav","family":"Gogoi","sequence":"additional","affiliation":[{"name":"Department of Cardiac Anaesthesia, Health City Hospital, Guwahati, Assam, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abhilasha","family":"Bhati","sequence":"additional","affiliation":[{"name":"Department of Radiology, Health City Hospital, Guwahati, Assam, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,1,6]]},"reference":[{"key":"R1-20260420","doi-asserted-by":"crossref","first-page":"189","DOI":"10.1055\/s-0033-1349166","article-title":"Diagnosis of coronary artery fistulas: Clinical aspects and brief review of the literature","volume":"22","author":"Sharma","year":"2013","journal-title":"Int J Angiol"},{"key":"R2-20260420","doi-asserted-by":"crossref","first-page":"W237","DOI":"10.2214\/AJR.13.11613","article-title":"Prevalence and types of coronary artery fistulas detected with coronary CT angiography","volume":"203","author":"Lim","year":"2014","journal-title":"AJR Am J Roentgenol"},{"key":"R3-20260420","doi-asserted-by":"crossref","first-page":"451","DOI":"10.1016\/S0894-7317(14)80282-4","article-title":"A five-chambered heart: Rare coronary artery anomaly with fistula draining into a separate interventricular cavity","volume":"5","author":"Ali","year":"1992","journal-title":"J Am Soc Echocardiogr"},{"key":"R4-20260420","doi-asserted-by":"crossref","first-page":"61","DOI":"10.1016\/S0894-7317(14)80419-7","article-title":"Echocardiographic evaluation of the five-chamber heart: A rare congenital coronary anomaly","volume":"7","author":"Jortner","year":"1994","journal-title":"J Am Soc Echocardiogr"},{"key":"R5-20260420","doi-asserted-by":"crossref","first-page":"55","DOI":"10.1002\/jcu.22639","article-title":"A dissecting aneurysm of interventricular septum resulting from congenital coronary artery fistula","volume":"47","author":"Wu","year":"2019","journal-title":"J Clin Ultrasound"},{"key":"R6-20260420","doi-asserted-by":"crossref","first-page":"149","DOI":"10.1016\/S0894-7317(99)70127-6","article-title":"Doppler echocardiographic features of coronary artery fistula: Report of 8 cases","volume":"12","author":"Barbosa","year":"1999","journal-title":"J Am Soc Echocardiogr"},{"key":"R7-20260420","first-page":"781","article-title":"The to and fro sign: The hallmark of pseudoaneurysm","volume":"3","author":"Rozen","year":"2001","journal-title":"Isr Med Assoc J"},{"key":"R8-20260420","doi-asserted-by":"crossref","first-page":"439","DOI":"10.1002\/clc.4960291005","article-title":"Coronary artery aneurysm: A review","volume":"29","author":"Pahlavan","year":"2006","journal-title":"Clin Cardiol"},{"key":"R9-20260420","doi-asserted-by":"crossref","first-page":"1026","DOI":"10.1016\/S0735-1097(02)01742-4","article-title":"Management of coronary artery fistulae.
