Large cameral coronary artery fistula in a 5 months old infant with unusual presentation and fatal outcome: -case report
Abstract
Abstract Background Congenital coronary fistulas (CAFs) are uncommon abnormalities communicating the coronary arteries with the cardiac chambers or portion of the systemic or pulmonary circulation. Over 90% of the cases drain into the right side of the heart with only 3% terminating in the left ventricle. Infants with a large CAFs may develop congestive heart failure. Case presentation A 5 months old female infant presented with labored breathing and worsening of bluish discoloration of the lips and extremities following a prolonged cry. She had a history of breastfeeding difficulty and noticeable bluish discoloration of the lips and extremities since birth. The infant was wasted and had a fast heart rate, bluish lips, and nail beds with clubbing of fingers and toes. A cardiac murmur was noted during her medical checkup. Chest x-ray showed cardiomegaly. Echocardiography and CT angiography showed large Cameral CAF involving the left main and left anterior descending artery draining into the left ventricle. The tricuspid valve was dysplastic, there was secundum ASD, and VSD with a right to left shunt. The patient developed episode of cyanotic spells after crying excessively following a CT angiographic procedure which culminated in respiratory arrest and her demise. She was managed as a case of hypoxic spells in the ICU before her death. Conclusion This report unveiled unfamiliar case of Cameral coronary artery fistula with left-to-left shunting, cyanosis, and dysplastic tricuspid valve.
