Heart valves can be repaired through
annuloplasty or valvuloplasty. Annuloplasty involves resizing heart valves and
a valvuloplasty procedure involves repairing heart valve leaflets, which have
calcium deposits or extra tissue on the leaflets. Although all valves may
undergo repair procedures, mitral valve repair is by far the most common
procedure, followed by tricuspid valve repair. Due to the extremely low numbers
of aortic and pulmonary valve procedures, for the purposes of this report,
their numbers are considered negligible.
The mitral and tricuspid valves are
atrioventricular valves that prevent backflow from the ventricles into the
atria during systole. Both valves are anchored to the wall of the ventricle by
chordae tendineae, which prevent the valve from inverting. The chordae
tendineae are attached to papillary muscles that create tension to hold the
valve.
In the past, the mitral valve has been
preferred for repair because of the large margin of safety that the valve
allows during the repair procedure. However, an article published in the New
England Journal of Medicine in November 2013 demonstrated that mitral valve
replacement provides a more durable correction of mitral regurgitation than
mitral repair. This has increased the popularity of mitral valve replacement
for the treatment of mitral valve defects.
Annuloplasty is used for restoring an
optimal orifice area and shape, providing support and preventing further
annular dilatation. Through disease or age, the tissue that supports the heart
valve’s opening, the annulus, can weaken and lose its shape. To repair this
condition, a device called an annuloplasty ring or band is sewn around the base
of the heart valve to reshape it and give it support.
An annuloplasty band or ring is made of
durable plastic, metal or fabric and may be flexible or rigid. These rings and
bands are designed to hold the natural shape, motion and flexibility of the
annulus. An annuloplasty repair procedure usually involves open heart surgery
requiring a median sternotomy, but may also be performed minimally invasively
via keyhole surgical techniques or percutaneously.
