Fc. Riess et al., A special retractor for limited access aortic valve replacement using a standard cannulation technique, MIN INVAS T, 9(6), 2000, pp. 393-395
We describe a new retractor for limited-access aortic valve replacement. St
andard cannulation technique can be used and the venous cannula is shifted
to the right retrosternal space and held in this position by the new device
, thus facilitating an unobstructed view of the operation field.
