Coronary artery fistula and bronchiectasis: case report and literature review

: Coronary artery fistula (CAF) is characterized by abnormal communication between the main coronary and cardiac chambers, pulmonary arteries, vena cava, systemic arteries veins, a rare malformation. Bronchiectasis involves remodeling persistent dilatation of bronchial airways. It can either be localized to one lung segment or diffused throughout whole lung. The incidence bronchiectasis has increased 566 per 100,000 over last decade. There 33% possibility that CAF lung-related disease will co-occur. However, merging mechanism these two diseases not been explored. We report case 61-year-old female with who was admitted our hospital dyspnea ankle edema. patient diagnosed artery-pulmonary angiography (CAG), which performed rule out stenosis. Using keywords “coronary fistula” “bronchiectasis” search inpatient system hospital, PubMed, Web Science, we found often occur due cardiovascular airway connection. Previous studies also support co-occur bronchiectasis. Based on findings, explain possible this co-occurrence aim improving diagnostic techniques therapeutic methods.
