Why the study?
Does Doppler echocardiography differentiate between constrictive pericarditis and restrictive cardiomyopathy based on respiratory variations in flow velocities?
Does Doppler echocardiography differentiate between constrictive pericarditis and restrictive cardiomyopathy based on respiratory variations in flow velocities?
Doppler echocardiography can effectively differentiate constrictive pericarditis from restrictive cardiomyopathy by identifying specific respiratory variations in ventricular filling velocities unique to constriction.

Supports respiratory Doppler differentiation of constrictive pericarditis from restrictive cardiomyopathy; leaves open need for prospective validation before clinical adoption.
A 1989 study studied this question.
