Abstract

Background: The diagnosis of constrictive pericarditis (CP) is challenging as there are currently no standard echocardiographic diagnostic criteria. In this retrospective case series, we analyzed and summarized the features of 25 patients with CP and proposed echocardiographic diagnostic criteria. It is hoped that the suggested criteria help professionals make decisions in their daily practice so that patients receive timely diagnosis and effective treatment. Methods: Twenty-five patients with CP were selected for this retrospective study. The clinical and echocardiographic imaging data were analyzed and summarized, and echocardiographic diagnostic criteria for CP were proposed. Results: The main clinical manifestations were fatigue, breathlessness, exertional dyspnea (88%), lower-limb edema (84%), hepatomegaly, and jugular vein filling (84%). Echocardiographic features comprised pericardial thickening (88%) and calcification (60%), pulmonary hypertension (52%), inferior vena cava dilation (80%), left and/or right atrial enlargement (100%), diastolic flattening of the left ventricular (LV) posterior wall (72%), septal shudder and bounce (64%), restrictive LV and right ventricular diastolic filling pattern (100%), early filling changes of mitral and tricuspid flow (80% and 60%, respectively), and mitral annulus reversus (73%). Conclusions: Echocardiography is a simple and valuable examination for CP. The echocardiographic diagnostic criteria are valid and worth promoting.
