2. Annuloplasty is repair of valve annulus (junction of the valve leaflets and the muscular heart wall) - narrows the diameter of the valve’s orifice, useful for valvular regurgitation 3. Chordoplasty is repair of chordae tendineae - done for mitral valve regurgitation – caused by stretched, torn or shortened chordae tendineae
