Chronic Constrictive Pericarditis: Understanding Its Clinical Characteristics

Chronic constrictive pericarditis is a condition that develops over time due to various underlying causes. One of the most common causes is prior tuberculous infection, which leads to thickening and scarring of the pericardium—the sac surrounding the heart. This thickening restricts the heart's ability to expand properly during diastole, ultimately impairing cardiac function and mimicking symptoms of right-sided heart failure.

Key Clinical Features of Chronic Constrictive Pericarditis

Patients often present with a range of systemic symptoms due to impaired venous return and fluid retention. Common manifestations include peripheral edema, particularly in the lower extremities, as well as neck vein distention, fatigue, and unexplained weight loss. Gastrointestinal symptoms such as loss of appetite and indigestion are also frequently observed, due to hepatic congestion and reduced blood flow to the digestive system.

Diagnostic Approaches and Challenges

Accurate diagnosis of chronic constrictive pericarditis typically involves a combination of imaging modalities. Techniques such as echocardiography, computed tomography (CT), and chest X-ray are essential for identifying pericardial thickening, calcification, and abnormal heart motion. However, because this condition often coexists with other cardiovascular or systemic illnesses, distinguishing it from restrictive cardiomyopathy or other forms of heart failure can be challenging.

Importance of Early Detection

Early identification and appropriate management are crucial in improving patient outcomes. Without timely intervention, chronic constriction can lead to progressive organ dysfunction and significant decline in quality of life. Physicians must maintain a high index of suspicion, especially in patients with a history of infections, autoimmune disorders, or prior heart surgery.
