Insights
Coronary cameral fistula (CCF), an abnormal coronary artery to cardiac chamber connection, can cause symptoms. Surgical intervention resolved symptoms in a young female patient with CCF diagnosed via CT coronary angiography.
Area of Science:
- Cardiology
- Medical Imaging
- Congenital Heart Disease
Background:
- Coronary cameral fistula (CCF) is a rare condition, occurring in less than 1% of the population.
- Most CCF cases are asymptomatic, but large fistulas can lead to significant symptoms and complications.
- Embryogenesis abnormalities are the usual cause of CCF.
Purpose of the Study:
- To present a case of symptomatic CCF in a young female.
- To highlight the diagnostic utility of computed tomography coronary angiography (CTCA).
- To demonstrate the efficacy of surgical treatment for CCF.
Main Methods:
- Echocardiography was used for initial suspicion of CCF.
- Computed tomography coronary angiography (CTCA) confirmed the diagnosis.
- Surgical intervention was performed for treatment.
Main Results:
- A young female presented with symptomatic CCF.
- CTCA provided definitive diagnosis of the coronary artery to cardiac chamber fistula.
- Surgical treatment resulted in complete symptom resolution.
Conclusions:
- CCF is an abnormal communication between coronary arteries and cardiac chambers.
- Large CCFs can cause angina pectoris via the coronary steal phenomenon and may necessitate surgery.
- Coronary CT angiography is a highly sensitive, non-invasive diagnostic tool for CCF.
Abstract:
Coronary cameral fistula (CCF) is defined as an abnormal connection between the coronary artery and any cardiac chamber. It usually appears due to abnormal embryogenesis and represents less than 1% of the population. Most CCF cases are asymptomatic, however large CCFs may cause symptoms and complications. We present a case of a young female with symptomatic CCF suspected on echocardiography and confirmed by computed tomography coronary angiography. She was successfully treated surgically with total improvement of symptoms.
Learning Points:
Coronary cameral fistula (CCF) is an abnormal communication between the coronary arteries and cardiac chambers. Most fistulas are asymptomatic, however, large CCFs can cause symptoms.CCF can cause angina pectoris due to the coronary steal phenomenon, and may require surgical intervention.Coronary computed tomography angiography is a highly sensitive method for detecting coronary artery fistulas noninvasively.
