Diagnostic Techniques for Constrictive Pericarditis
Constrictive pericarditis(CP)is caused by various causes of pericardial thickening,adhesions and fibrosis,resulting in limited diastolic function of the heart,so that the symptoms and signs of right heart failure appear in the early stage of CP.If not treated in time,it can lead to adverse cardiovascular events such as total heart failure.Due to non-specific symptoms and insidious onset,CP is often misdiagnosed as other cardiovascular or non-cardiovascular diseases,such as coronary heart disease,restrictive cardiomyopathy,and congestive liver disease.Now the diagnosis of CP focuses on non-invasive imaging techniques,for example,echocardiography is the primary examination method,CT and magnetic resonance imaging can show the anatomical structure of the pericardium and assess pericardial inflammation.When the non-invasive techniques fail to make a clear diagnosis,hemodynamics can be monitored and peripheral venous pressure measured for elevated venous pressure due to CP can be used to aid diagnosis.If none of the above can be determined,the diagnosis can be confirmed by surgical pathological biopsy.The diagnosis of CP is challenging,and it is easy to be missed or misdiagnosed.Therefore,this article reviews the current status and progress of diagnostic techniques for this disease.
