Percutaneous focused force aortic valvuloplasty using the buddy-catheter technique.
Percutaneous transcatheter aortic valvuloplasty is seriously limited by high restenosis rates. We report a case where the use of a buddy-catheter technique during balloon inflation allowed increased focused force onto calcified stiff commissures with an increase in resultant valve area. This technique may result in further valve area enlargement and decrease the restenosis rate.
