Giant congenital fistula of the circumflex coronary artery with drainage into right atrium.

A dilated and tortuous fistula from circumflex coronary artery draining into the right atrium was diagnosed by transthoracic echocardiography and selective angiography in a 64-year old female. Transcatheter closure was excluded by the cardiologist because of the presence of a large huge at the drainage site so the patient was scheduled for surgical ligation. Intraoperative and postoperative controls were performed by echocardiography. The Authors discuss on differential diagnosis, indications and types of treatment in all cases presenting coronary artery fistula.
