Constrictive pericarditis (CP) is a type of diastolic coronary heart failure that arises as a result of an inelastic pericardium inhibits cardiac filling. This dysfunction have to be thought of within the differential prognosis for unexplained coronary heart failure, notably when the left ventricular ejection fraction is preserved. Threat components for the event of CP embrace prior cardiac surgical procedure and radiation remedy, however most instances are nonetheless deemed to be idiopathic. Making the prognosis could also be difficult and requires meticulous echocardiographic evaluation, usually supplemented by cross-sectional cardiac imaging and haemodynamic catheterisation. The important thing pathophysiological ideas, which function the premise for most of the diagnostic standards, stay: (1) dissociation of intrathoracic and intracardiac pressures and (2) enhanced ventricular interplay. Full surgical pericardiectomy is the one efficient remedy for continual CP. A subset of sufferers with subacute inflammatory CP, usually recognized by cardiac MRI, might reply to anti-inflammatory therapies.
