You can get a mitral valve replacement done at a surgical institute or hospital by a qualified surgeon. You can learn more about mitral valve replacement online at the Wikipedia.
Patients treated by mitral valve replacement for mitral insufficiency can expect relief of symptoms. Improvement in myocardial function is not likely, but the current status is preserved.
Risks specifically associated with mitral valve replacement include embolism, bleeding, and operative valvular endocarditis.

Mitral valve repair is performed to improve the function of the diseased valve so that it correctly controls the direction of blood flow.
Smoking causes heart disease and increases your chance of heart failure vastly. If your heart is already in bad shape which it is if you need a mitral valve replacement which is on the left side of the heart. Then I would say that you are only damaging the heart even more if it is in bad shape as is.
How many of these procedures has the surgeon performed in the last year?in the last five years?What is the surgeon's morbidity and mortality rate with mitral valve repair?What will happen if the repair fails?
Cardiothoracic and cardiovascular surgeons perform mitral valve repair. Surgeons are trained during their residency to perform these procedures, although a certain level of skill is required for perfection of the technique.
Mitral stenosis
In rare cases, mitral valve prolapse can cause sudden death. Mitral Valve Prolapse (MVP) could kill you if it is serious. There are some symptoms but most people don't get them. There are a racing heart, chest pains, dizziness, fatigue, and shortness of breath. You can get a heart replacement but it is extremely expensive usually between $500 and $10000.
