Fig. 7From: Effect of reinforcement volume fraction and orientation on a hybrid tissue engineered aortic heart valve with a tubular leaflet designA simplified top view of asymmetric modes that can occur during closing of the valve; a–c buckling of the closed valve edges, d slipping of one leaflet over the others, and e one leaflet sliding in between the other two. These modes are avoided using a 1/6th model with symmetry.Back to article page
