Surgical management of congenital coronary artery fistula
Insights
Congenital coronary artery fistula (CAF) surgical treatment is safe and effective for most patients, with good long-term results. However, intervention in asymptomatic cases remains debated.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Surgical Treatment
Background:
- Congenital coronary artery fistula (CAF) is a rare condition.
- Diagnosis often relies on advanced imaging techniques.
- CAF can lead to significant cardiac complications.
Purpose of the Study:
- To evaluate the surgical outcomes of congenital coronary artery fistula.
- To assess the safety and efficacy of surgical correction for CAF.
- To discuss the indications for surgical intervention in CAF patients.
Main Methods:
- Retrospective review of 8 patients surgically treated for CAF over 6 years.
- Diagnostic methods included retrograde aortography and selective coronary arteriography.
- Surgical approaches involved cardiopulmonary bypass or direct suture ligation.
Main Results:
- All 8 patients had successful surgical outcomes with no mortality or morbidity.
- Drainage sites were predominantly on the right side of the heart.
- Long-term results were reported as good for all treated patients.
Conclusions:
- Surgical correction of congenital coronary artery fistula is a safe and effective treatment.
- Routine surgical intervention is recommended for symptomatic CAF patients.
- The necessity of surgery for asymptomatic CAF patients requires further consideration.
Abstract:
Over a period of 6 years, 8 patients underwent surgical treatment at our hospital for congenital coronary artery fistula (CAF). The ages of the patients ranged from 4 months to 50 years (mean 22.7 years). Continuous heart murmurs could be heard in all patients, except one. The diagnosis was made by retrograde aortography and/or selective coronary arteriography. Only one patients had associated cardiac disease. All the drainage sites of the CAF were on the right side of the heart (right atrium, right ventricle, pulmonary artery). Two patients had both right and left CAFs. Symptoms due to "coronary steal" by a coronary artery fistula were demonstrated by a nuclear medicine study in one of our patients. Four patients were operated on with the aid of cardiopulmonary bypass. The other 4 patients were treated with suture ligation directly. There was no surgical mortality or morbidity, and the longterm results have been good. Since surgical correction is safe and effective, it would appear desirable for all patients with CAF be operated on. However, surgical intervention is controversial in asymptomatic patients.
