Abstract
Coronary sinus ostial atresia(CSOA) is a rare cardiac malformation.
The morbidity rate is 0.1%.1 We report here
on a rare case of an incidentally found CSOA with unroofed coronary
sinus(UCS) and persistent left
superior vena cava(PLSVC) in an
adult patient. Diagnostic methods included echocardiography,
multidetector row computed tomography.
