Our Summary
This research paper explores the different outcomes between two types of heart surgeries in elderly patients: mitral valve repair and mitral valve replacement. The study looked at data from patients over 75 years old who had either repair or replacement surgery for their damaged heart valve between 2010 and 2013.
The results showed that there were 260 patients in total, with 145 undergoing repair and 115 undergoing replacement. Importantly, the study found that the patients who had their heart valve replaced were more likely to die in the hospital than those who had their valve repaired (9.6% compared to 1.4%). Among a matched group of 78 patients from each type of surgery, none of the repair group died in the hospital, compared to about 8% in the replacement group.
More so, the study found that the chances of surviving 1, 2, and 3 years after the surgery were higher for the repair group than for the replacement group. The researchers concluded that, at least in the short to medium term, repair surgery is linked with better outcomes for elderly patients with degenerative heart valve disease than replacement surgery. However, they also noted that the study’s conclusions are limited because it was a retrospective analysis, meaning it looked at past data, rather than conducting a new, controlled experiment.

Doctor’s Tip
Based on these findings, a doctor might recommend to a patient that mitral valve repair may be a better option for them compared to replacement, especially if they are elderly. It is important for patients to discuss their individual situation with their healthcare provider to determine the best course of action. Additionally, maintaining regular follow-up appointments and following a healthy lifestyle post-surgery can help improve overall outcomes and recovery.
Suitable For
Mitral valve replacement is typically recommended for patients who have severe damage to their mitral valve that cannot be repaired, such as those with severe mitral regurgitation or stenosis. Patients with certain medical conditions, such as endocarditis or rheumatic heart disease, may also be recommended for mitral valve replacement.
Additionally, patients who are not good candidates for mitral valve repair, either due to the complexity of the repair needed or other medical issues, may be recommended for replacement instead. Patients who have had previous failed repair surgeries may also be candidates for mitral valve replacement.
Overall, the decision to recommend mitral valve replacement is based on a variety of factors, including the severity of the valve damage, the patient’s overall health and medical history, and the expertise of the surgical team. It is important for patients to discuss their options with their healthcare provider to determine the best course of treatment for their specific situation.
Timeline
Before mitral valve replacement, a patient may experience symptoms such as shortness of breath, fatigue, chest pain, palpitations, and swollen ankles. They may undergo diagnostic tests such as echocardiograms, electrocardiograms, and cardiac catheterization to determine the severity of their condition. Once it is determined that mitral valve replacement is necessary, the patient will undergo preoperative preparation including blood tests, imaging scans, and consultations with the surgical team.
During mitral valve replacement surgery, the patient is placed under general anesthesia and the chest is opened to access the heart. The damaged mitral valve is removed and replaced with a mechanical or biological prosthetic valve. The patient is then monitored closely in the intensive care unit postoperatively for any complications.
After mitral valve replacement, the patient will continue to be monitored in the hospital for a few days to ensure the proper functioning of the new valve and to manage pain and any potential complications. Physical therapy may be initiated to help the patient regain strength and mobility. Once discharged from the hospital, the patient will be prescribed medications to prevent blood clots, infection, and to manage any underlying heart conditions.
Over the following weeks and months, the patient will attend follow-up appointments with their healthcare team to monitor their progress and adjust medications as needed. Cardiac rehabilitation may be recommended to help the patient regain cardiovascular fitness and improve their overall health. With proper care and adherence to medical recommendations, most patients can expect to return to a normal quality of life after mitral valve replacement.
What to Ask Your Doctor
Some questions a patient should ask their doctor about mitral valve replacement include:
- What are the benefits of mitral valve replacement compared to repair in my specific case?
- What are the potential risks and complications associated with mitral valve replacement surgery?
- How long is the recovery process after mitral valve replacement surgery?
- What type of prosthetic valve will be used for the replacement and how long does it typically last?
- Will I need to take blood thinners or other medications after the surgery?
- What lifestyle changes will I need to make after mitral valve replacement surgery?
- How often will I need follow-up appointments and monitoring after the surgery?
- Are there any alternative treatment options to mitral valve replacement that I should consider?
- What is the success rate of mitral valve replacement surgery in patients of my age group?
- Can you provide me with information about the surgeon’s experience and success rate with mitral valve replacement procedures?
