Our Summary
This study looks at the outcomes of a type of heart surgery to replace a faulty pulmonary valve, which can happen after surgery for congenital heart disease. The researchers compared two types of replacement valves: one made from pig tissue and another made from tissue around the heart, called the pericardium.
The study looked at 82 adult patients who had this surgery between 2004 and 2016. They found that both types of replacement valves worked well for up to eight years after surgery. There were no significant differences between the two groups, although the group with the pig tissue valve had a slightly longer follow-up period.
The volume of the right ventricle (one of the heart’s chambers) decreased significantly in both groups after surgery, but the function of this chamber didn’t change. The volume of the left ventricle increased in both groups, but this was only significant in the group with the pericardium valve. Again, the function of this chamber didn’t change.
Only one patient died while in the hospital (1.1% of cases), and there were no deaths after discharge. There were also no cases where patients needed another valve replacement surgery. By eight years post-surgery, 93.8% of the pig tissue valve group and 100% of the pericardium valve group had not needed any further intervention.
In conclusion, both types of replacement valves worked well in adults for up to eight years after surgery.

Doctor’s Tip
A helpful tip a doctor might give to a patient about pulmonary valve replacement is to follow up regularly with your cardiologist to monitor the function of the replacement valve and ensure everything is working properly. It’s also important to maintain a healthy lifestyle, including regular exercise and a balanced diet, to keep your heart healthy and reduce the risk of any complications. If you experience any new symptoms or changes in your health, be sure to contact your healthcare provider immediately.
Suitable For
Patients who may be recommended for pulmonary valve replacement include those with congenital heart disease who have developed pulmonary valve dysfunction, such as pulmonary regurgitation or stenosis. These patients may experience symptoms such as shortness of breath, fatigue, or chest pain, and may have complications such as right ventricular dysfunction or arrhythmias. Pulmonary valve replacement may also be considered for patients with a history of previous heart surgery, such as repair of tetralogy of Fallot or other congenital heart defects. It is important for patients to be evaluated by a cardiologist or cardiac surgeon to determine if pulmonary valve replacement is necessary and to discuss the best treatment options.
Timeline
Before the pulmonary valve replacement, the patient likely experienced symptoms such as shortness of breath, chest pain, fatigue, and fainting. They would have undergone diagnostic tests such as echocardiograms and cardiac catheterizations to determine the need for surgery. The patient would have also met with their healthcare team to discuss the procedure, risks, and recovery process.
After the pulmonary valve replacement, the patient would have been closely monitored in the hospital for any complications or signs of infection. They would have started a cardiac rehabilitation program to help with recovery and improve heart function. The patient would have continued to see their healthcare team for regular follow-up appointments to monitor their progress and ensure the valve was functioning properly.
Overall, the timeline for a patient before and after pulmonary valve replacement involves a period of evaluation, surgery, recovery, and ongoing follow-up to ensure the success of the procedure and the patient’s overall heart health.
What to Ask Your Doctor
Some questions a patient should ask their doctor about pulmonary valve replacement include:
- What are the potential risks and complications associated with pulmonary valve replacement surgery?
- How long is the recovery period after surgery, and what can I expect during the recovery process?
- Will I need to take medication after surgery, and if so, what are the potential side effects?
- How often will I need follow-up appointments after surgery, and what tests will be done to monitor the function of the new valve?
- Are there any lifestyle changes or restrictions I need to follow after surgery?
- What symptoms should I watch out for that may indicate a problem with the new valve?
- Are there any long-term effects or potential complications I should be aware of?
- Will I need any additional procedures or interventions in the future related to the pulmonary valve replacement?
- How does the choice between a pig tissue valve and a pericardium valve impact long-term outcomes and quality of life?
- Are there any specific recommendations or resources for support or education about living with a replacement pulmonary valve?
