Coronary pulmonary artery fistulas may lead to grow aneurysm formation via chronic high-flow shunting. Their coexistence is rare in elderly patients without prior Kawasaki disease.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case summary<\/jats:title>\n                    <jats:p>An 83-year-old woman with hypertension, dyslipidaemia, and type 2 diabetes mellitus was referred for evaluation of an abnormal mediastinal contour. Chest computed tomography showed a 43 \u00d7 33\u2005mm left anterior descending artery aneurysm with a fistulous to the pulmonary artery, grown from 30 \u00d7 20\u2005mm over 10 years. Right heart cardiac catheterization showed no evidence of pulmonary artery hypertension with a mild shunt flow (Qp\/Qs: 1.15). Despite being asymptomatic, the aneurysm's size and growth warranted intervention. Considering her age and comorbidities, transcatheter coil embolization was selected over surgical or stent-based therapies. Coils were deployed using intravascular ultrasound (IVUS) and a balloon-assisted technique, successfully occluding the aneurysm without compromising distal flow. Follow-up angiography at 6 months and echocardiography up to 3 years confirmed sustained occlusion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>This case highlights that even in asymptomatic elderly patients, large and expanding CAAs with fistulas warrant careful evaluation due to the risk of rupture. Transcatheter coil embolization provided a safe and effective treatment alternative to surgery, especially in high-risk anatomical and clinical settings. IVUS and balloon assistance were critical to procedural success, and long-term follow-up demonstrated sustained aneurysm exclusion.<\/jats:p>\n
