Right coronary artery fistula to the coronary sinus.

: We report the case of a 26-year-old asymptomatic woman, who presented for consultation after the detection of a cardiac murmur in a medical routine recognition. Doppler echocardiography and the 64-row multidetector computed tomography showed the presence of a significant enlargement of the right coronary artery winding in the contour of the right ventricle and its fistulosa connection to the coronary sinus. Although the coronary fistula in our patient had a considerable size, there was no ventricular dilation, and thus we chose, according to the desire of the patient, not to intervene, and to evaluate her regularly.
