Constrictive pericarditis and restrictive cardiomyopathy: similarities and differences.

Constrictive pericarditis and restrictive cardiomyopathy, two relatively uncommon clinical conditions, create a diagnostic dilemma primarily because of the many similarities in both their clinical and hemodynamic presentations. However, considerable differences exist in the pathophysiology, management, and prognosis between these two syndromes. Furthermore, the precise diagnosis of constrictive pericarditis and restrictive cardiomyopathy is mandatory, as the former is often curable whereas only palliative treatments are available for the latter. In this brief review, similarities and differences in the various aspects of constrictive pericarditis and restrictive cardiomyopathy will be discussed.
