Constrictive Pericarditis: Causes, Symptoms, Diagnosis, and Treatment
Constrictive pericarditis is a condition in which the pericardium, the sac that surrounds the heart, becomes thick and rigid, limiting the ability of the heart to fill with blood. This can lead to symptoms such as shortness of breath, fatigue, and swelling in the legs and abdomen.

Causes of Constrictive pericarditis
Constrictive pericarditis can be caused by a number of factors, including:
Infections: Inflammation of the pericardium caused by infections such as tuberculosis, bacterial or viral pericarditis.
Autoimmune disorders: Autoimmune disorders such as lupus, rheumatoid arthritis, or scleroderma can lead to inflammation of the pericardium.
Radiation therapy: Radiation therapy for cancers in the chest area can cause pericardial inflammation and scarring.
Idiopathic: In some cases, the cause of constrictive pericarditis is unknown.
Symptoms of Constrictive pericarditis
The symptoms of constrictive pericarditis can be similar to those of heart failure, including:
- Shortness of breath, especially during physical activity
- Fatigue and weakness
- Swelling in the legs, ankles, and feet
- Abdominal swelling
- Decreased appetite and weight loss
- Chest discomfort
- Irregular heartbeat
Constrictive pericarditis can cause a range of symptoms that can affect the person's quality of life
Complications of Constrictive Pericarditis
Constrictive Pericarditis leads to the constriction of the heart and can cause various complications, including:
Constrictive pericarditis can lead to heart failure due to impaired heart function, which can result in symptoms such as shortness of breath, fatigue, and swelling in the legs and abdomen.
Arrhythmias:
Constrictive pericarditis can cause irregular heart rhythms or arrhythmias, which can be life-threatening if left untreated.
Edema:
Constrictive pericarditis can cause fluid buildup in the legs, abdomen, and other parts of the body, leading to swelling or edema.
Liver and kidney problems:
Constrictive pericarditis can lead to liver and kidney problems due to impaired blood flow and fluid buildup.
Blood clots:
Constrictive pericarditis can increase the risk of blood clots, which can lead to stroke or pulmonary embolism.
Constrictive pericarditis can cause fluid to accumulate in the pericardium, leading to pericardial effusion.
Constrictive pericarditis can cause cardiac tamponade, which is a medical emergency where the fluid accumulation in the pericardium puts pressure on the heart, impairing its function.
Constrictive pericarditis can lead to various complications that can be life-threatening if left untreated.
Diagnosis of Constrictive pericarditis
The diagnosis of constrictive pericarditis involves a careful evaluation of the patient's symptoms, medical history, and physical examination. Tests that may be used to confirm the diagnosis include:
Echocardiogram: This is a non-invasive test that uses sound waves to produce images of the heart. It can show the thickened pericardium and any restricted movement of the heart.
CT or MRI scan: These imaging tests can provide detailed images of the heart and pericardium.
Cardiac catheterization: This is an invasive procedure in which a thin, flexible tube is inserted through a blood vessel in the groin or arm and guided to the heart. It can measure the pressure inside the heart chambers and help determine the severity of the constriction.
Treatment for Constrictive pericarditis
Constrictive pericarditis is a rare but serious complication of pericardial effusion, in which the pericardium becomes thick and rigid, limiting the heart's ability to fill with blood. Treatment for constrictive pericarditis typically involves a combination of medications and, in some cases, surgery.
Medications
In mild cases of constrictive pericarditis, medications may be used to manage symptoms and reduce inflammation. Nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids are often used to reduce inflammation and relieve pain. Diuretics may be used to reduce fluid retention and swelling.
Pericardiectomy
In more severe cases of constrictive pericarditis, surgery may be necessary to remove part or all of the pericardium. This procedure, called pericardiectomy, can improve the heart's ability to fill with blood and reduce symptoms of heart failure. A pericardiectomy is a major surgery that involves a large incision in the chest and a hospital stay of several days to weeks.
Pericardiocentesis
In some cases, a procedure called pericardiocentesis may be used to remove excess fluid from the pericardial sac. This procedure involves inserting a needle into the chest to drain the fluid. Pericardiocentesis may provide temporary relief of symptoms, but it is not a long-term solution for constrictive pericarditis.
Balloon pericardiotomy
In select cases, a minimally invasive procedure called balloon pericardiotomy may be an option. This procedure involves inflating a small balloon inside the pericardial sac to create a small opening, allowing fluid to drain and relieve pressure on the heart. Balloon pericardiotomy is less invasive than pericardiectomy, but it may not be effective in all cases of constrictive pericarditis.
The choice of treatment for constrictive pericarditis depends on the severity of the condition and the individual patient's medical history and preferences. Treatment may involve a combination of medications and surgery. It's important to work closely with a healthcare provider to determine the best course of treatment and to manage any ongoing symptoms or complications.
Prognosis of Constrictive Pericarditis
The prognosis of constrictive pericarditis depends on several factors, including the underlying cause, the severity of symptoms, and the response to treatment. In general, the prognosis is better when the condition is diagnosed early and treated promptly.
If left untreated, constrictive pericarditis can lead to progressive heart failure, arrhythmias, and other complications that can be life-threatening. However, with appropriate treatment, many people with constrictive pericarditis can achieve significant improvement in symptoms and quality of life.
It is important to work with a healthcare professional to determine the best course of treatment for your specific situation. Regular follow-up care is also important to monitor for any recurrence of symptoms and to adjust treatment as necessary.
