Comprehensive characterization of constrictive pericarditis using multiparametric CMR.

Cardiac magnetic resonance (CMR) is uniquely placed to characterize constrictive pericarditis. CMR comprehensively defines pericardial and myocardial anatomy as well as their structural and functional relationship. Indeed, through evaluation of regional myocardial deformation, ventricular interaction and venous return, CMR can accurately assess the physiological consequences of pericardial constriction. Furthermore, CMR provides in vivo insight into pericardial histology. As such, the diagnosis of constrictive pericarditis has become possible using a single, noninvasive investigation.
