Cardiac Valve Replacement
Clinical conditions that require a surgical procedure to replace the valve with
either a mechanical valve or a porcine valve include:
■ Acquired valvular dysfunction
■ Mitral valve stenosis
■ Mitral valve regurgitation
■ Mitral valve prolapse
■ Aortic stenosis
■ Aortic regurgitation
■ Pulmonary stenosis (less common)
In some cases of damaged aortic valves, the patients’ own pulmonary valve
can be used to replace the aortic valve, and then the pulmonary valve is
replaced with an artificial valve (the Roth procedure). This is ideal for people
who cannot or will not take blood thinners for the rest of their life. The surgical
procedure is the same as open-heart surgery except the heart is not bypassed,
only the valve is replaced, or it can be minimally invasive; techniques include
laparoscopic or endoscopic robot-assisted and percutaneous surgery.
