Chronic pericardial constriction is a condition where the sac surrounding the heart (the pericardium) becomes thickened and tight over time, restricting the heart’s ability to pump properly. In this article, we’ll break down the causes, symptoms, diagnosis, treatments, and surgical options for this condition in easy-to-understand language.
Chronic pericardial constriction occurs when the pericardium, a protective sac around the heart, becomes thickened and stiff. This stiffness restricts the heart’s movement, making it harder for it to fill and pump blood efficiently.
Types of Chronic Pericardial Constriction:
There are no specific types of chronic pericardial constriction, but it can be classified based on severity and underlying causes.
Causes of Chronic Pericardial Constriction:

- Pericardial biopsy: Removes a sample of pericardial tissue for analysis.
- Exercise tolerance test: Monitors heart function during physical activity.
- Holter monitor: Records heart rhythm over a period of time, usually 24-48 hours.
- Coronary angiography: Checks for blockages in the coronary arteries.
- Cardiopulmonary exercise testing: Measures heart and lung function during exercise.
- Chest CT angiography: Evaluates blood vessels in the chest.
- Positron emission tomography (PET) scan: Detects areas of abnormal metabolic activity in the heart.
Treatments for Chronic Pericardial Constriction:

- Cardiac rehabilitation: Supervised exercise program to improve heart health.
- Oxygen therapy: Supplemental oxygen to improve breathing.
- Heart failure medications: Such as ACE inhibitors or beta-blockers.
- Anticoagulants: Prevent blood clots.
- Vasodilators: Dilate blood vessels to reduce strain on the heart.
- Implantable cardioverter-defibrillator (ICD): For those at risk of dangerous arrhythmias.
- Cardiac resynchronization therapy (CRT): Helps coordinate heart contractions.
