[Coronary sinus type atrial septal defect diagnosed by two-dimensional color Doppler echocardiography: a case report].
This is a case report of coronary sinus type atrial septal defect (ASD) diagnosed preoperatively by two-dimensional color Doppler echocardiography. A 22-year-old asymptomatic woman was admitted for preoperative cardiac evaluation. A cardiac murmur and cardiomegaly had been noted at a routine examination which included electrocardiography and chest radiography, and M-mode echocardiography suggested the presence of a secundum type ASD. Color Doppler echocardiography revealed a left to right atrial shunt flow through the coronary sinus ostium into the right atrium. By peripheral contrast echocardiography, a negative contrast echo from the coronary sinus ostium was observed within the right atrium and persistent left superior vena cava was excluded. At operation, a 2 X 3 cm defect was demonstrated at the interatrial septum in the vicinity of the coronary sinus ostium. This is the first reported case of a coronary sinus type ASD diagnosed preoperatively by color Doppler echocardiography.
