ABSTRACT
Although it is attractive, a limitation of aortic valve (AV) replacement (AVR) through a mini-thoracotomy approach (mini-AVR) is the limited exposure of the AV. Here, we present a simple exposure technique named "suspending commissural sutures" for a more efficient mini-AVR. The technique involves making 3 half-depth stitches with 1-0 silk at each of the commissures, which are anchored to each corresponding pericardial surface. These stitches are tightened up so that the aortic root is axially expanded and is pulled upward. The technique of suspending commissural stitches seems to offer reasonable exposure of the AV in mini-AVR, and shows excellent early surgical outcomes.
