Abstract
A method of treating a deficient mitral valve without open heart surgery is disclosed. A support band is advanced from a delivery catheter and positioned around native leaflets of the deficient mitral valve. The support band is preferably formed of a shape memory material and is configured to assume a curved shape upon advancement from the delivery catheter. While the support band is positioned around the native leaflets of the mitral valve, an expandable prosthetic heart valve is delivered through an apex of the left ventricle and into the mitral valve. The expandable prosthetic heart valve is then expanded within the mitral valve, thereby causing one or more of the native leaflets of the mitral valve to be frictionally secured between the support band and the prosthetic heart valve.
