[Surgical technique of leaflet extension in aortic valve regurgitation].
Detailed procedure of the leaflet extension technique in aortic valve regurgitation is described. The concept of the technique is to create a wide and deep coaptation zone by extending the prolapsed leaflets using glutaraldehyde-preserved autologous pericardium, and by suspending the commissures. The leaflet extension technique is a procedure of choice for aortic valve regurgitation in young patients who need to avoid strict anticoagulation therapy. A careful long-term follow-up is necessary to evaluate the durability of glutaraldehyde-preserved pericardium in aortic position.
