Pericardium ;Pericarditeconstrictive ;Imagerie ;Imagerie parresonancemagnetiqueCP may involve only portions of the pericardium. In such cases, the condition is named‘localized CP’. Imaging methodologies play an important role in the diagnosis of thiscondition.A 55-year-old man with a history of tuberculosis presented with signs of heart failure.Chest X-ray showed pericardial calcifications confirmed on computed tomography(Fig. 1). Echocardiography showed pericardial hyperecogenicity at the mid portion of bothleft and right ventricular walls and left atrium enlargement (Fig. 2). Contractile dilatationof the apex was present. In M-mode tracing of the mitral valve, there was a steep E—Fslope, as for rapid early diastolic filling. Pulsed-wave Doppler showed respiratory varia-tion in transmitral flow: increased early diastolic filling during expiration compared withinspiration.CMR imaging in the four-chamber plane showed a focally thickened pericardium atthe level of the middle right and left ventricles, causing localized ventricular constriction(Fig. 3A). In particular, CMR showed an apical right and left ventricular contractile pseudo-ballooning deformation due to the higher intraventricular filling pressure in areas withoutpericardial constriction (Fig. 3B and C; Supplementary data, Video 1). As usually seen inconstriction, real-time cine magnetic resonance on the interventricular septum with deepbreath showed abnormal interventricular coupling.
