Clinical heart failure with normal systolic function is suggestive of diastolic dysfunction. This can result from myocardial or pericardial disorders. Myocardial disorders are a broad range of pathologies leading to restrictive physiology. Amyloidosis is a prototype of restrictive cardiomyopathy leading to diastolic dysfunction. Pericardial disorders leading to diastolic heart failure are usually in the form of constrictive physiology. Differentiation between restrictive and constrictive pathologies is often difficult and require careful attention to hemodynamic and Doppler echocardiographic features.
