Insights
Two patients with coronary artery fistulas and aneurysms underwent successful endovascular repair. This minimally invasive technique closed the abnormal connections, preventing further complications.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Surgery
Background:
- Coronary artery fistulas (CAFs) are abnormal connections between a coronary artery and a cardiac chamber or vessel.
- Coronary artery aneurysms (CAAs) can be associated with CAFs, increasing the risk of rupture or thrombosis.
Observation:
- Two cases of right coronary artery fistula with aneurysm formation were identified.
- Angiography revealed aneurysms draining into the right atrium and right ventricle.
Findings:
- Successful endovascular closure of the coronary artery inflow ostium to the aneurysm was achieved using aneurysmorraphy.
- Postoperative recovery was uneventful with no residual shunts detected on follow-up angiography.
Implications:
- Endovascular treatment offers a minimally invasive option for complex coronary artery fistulas with aneurysms.
- This approach can lead to favorable clinical outcomes and avoid the need for open-heart surgery.
Abstract:
Two cases of coronary artery fistula with coronary artery aneurysm were reported. Coronary angiography showed dilated right coronary artery with the formation of aneurysm drained to the right atrium and to the right ventricle respectively. The inflow ostium from the coronary artery to the aneurysm were closed from inside adding aneurysmorraphy. Postoperative clinical courses were uneventful and residual shunts were not detected by angiography. We reported these cases with literature.
