Transcatheter Closure of Right Coronary Artery-Pulmonary Artery Fistula

A platinum-fibered microcoil was used to occlude a coronary artery to pulmonary artery fistula. The patient was a 32-year-old woman with chest pain, palpitation and shortness of breath for 4 years. Her ECG, exercise test and thallium scintigraphy were normal. In the right coronary injection, a fistula was demonstrated from the sinus node artery of the right coronary artery to pulmonary artery which was 1.3 mm in diameter. Qp/Qs was calculated 1.42 with the Fick method. A 2x10 mm fibered platinum microcoil was used for transcatheter occlusion. In the control coronary angiography there was virtually no shunt 15 min after the procedure. Transcatheter occlusion is an alternative treatment technique to surgery in the coronary artery fistulas. The use of this technique leads to a precise and effective occlusion of the fistula, resulting in less myocardial damage and reduces morbidity. Much shorter hospital stay is needed for this technique.
