Can constrictive pericarditis be seen on Echo?
Echocardiography allows differentiation of constrictive pericarditis from restrictive myocardial disease and severe tricuspid regurgitation.
How do you rule out constrictive pericarditis on Echo?
The presence of ventricular septal shift in combination with either medial e’ ≥ 9 cm/s or hepatic vein expiratory diastolic reversal ratio ≥ 0.79 (Hepatic vein diastolic reversal velocity / diastolic forward flow velocity) was 87% sensitive and 91% specific for the diagnosis of constrictive pericarditis.
What is the meaning of constrictive?

What does constrictive mean?
Definitions of constrictive. adjective. restricting the scope or freedom of action. synonyms: confining, constraining, limiting, restricting restrictive.
What are the complications of constrictive pericarditis?
Chronic constrictive pericarditis. Some people with long-term (chronic) pericarditis develop permanent thickening and scarring of the pericardium, which prevents the heart from filling and emptying properly. This unusual complication often leads to severe swelling of the legs and abdomen and shortness of breath.
Why is the Y descent prominent in constrictive pericarditis?
The jugular x and y descents are prominent in CP, due to exaggerated longitudinal annular motion and prominent early ventricular filling, respectively. In contrast, restrictive cardiomyopathy demonstrates blunting of the x descent, due to impaired atrial relaxation and atrial myopathy.
What do you need to know about constrictive pericarditis?
Constrictive pericarditis (CP) is a form of diastolic heart failure that arises because an inelastic pericardium inhibits cardiac filling. This disorder must be considered in the differential diagnosis for unexplained heart failure, particularly when the left ventricular ejection fraction is preserv …
What happens when the pericardium limits the diastolic filling?
When the abnormal pericardium limits diastolic filling, there are a series of hemodynamic consequences which manifest as fatigue, dyspnea, abdominal bloating, peripheral edema, or right heart failure. These clinical manifestations of constrictive pericarditis are similar to those due to a cardiomyopathy.
What are the symptoms of constrictive pericarditis dyspnea fatigue?
Constrictive Pericarditis Dyspnea Fatigue JVD Hepatomegaly and ascites Edema Neck veins distend with inspiration (Kussmaul’s sign) Pericardial knock (early diastolic sound) Afib in 20%
What is the normal thickness of the pericardium?
Normal pericardial thickness is 2 mm or less. A rigid and/or thickened pericardium is the anatomic substrate responsible for the constrictive physiology.
