[Clinical Experience of Beating Heart Atrial Septostomy Using a Device for Coronary Artery Anastomosis Site Creator].

BACKGROUND

Intra-atrial communication was mandatory for several congenital cardiac diseases, such as pulmonary atresia with intact ventricular septum (PA/IVS), and either sided aortoventricular valve atresia. We assessed whether the new methods of atrial septal defect(ASD)creation was effective.

METHODS

We experienced 4 cases of the surgical atrial septostomy performed under on-pump beating. We used a new device, a circular punch out defect creator.

RESULTS

All cases were alive. The mean ASD diameter was enlarged from 4.37 mm to 5.55 mm and the mean ASD shunt flow was significantly decreased from 1.47 m/s to 1.11 m/s.

CONCLUSIONS

We performed the surgical atrial septostomy using an aortic puncher under beating heart effectively and safely.
