The differentiation between restrictive cardiomyopathy and constrictive pericarditis: the impact of the imaging techniques.
The differentiation between constrictive pericarditis and restrictive cardiomyopathy remains a difficult problem for clinical cardiologists. Recent advances in imaging techniques and the understanding of diastolic function have created a new diagnostic approach to this problem.  In this article we will summarize the recent advances in the understanding of the pathophysiology of both disorders and how this is reflected mainly in the use of flow imaging techniques, such as Doppler echocardiography and radionuclide angiography.  Combined with the advances in the radiological imaging of the pericardium by means of computed tomography and magnetic resonance imaging, an integrated approach to the differential diagnostic problem is proposed and an algorithm for clinical use has been designed.
