Echocardiogram during follow-up revealing signs indicative of constrictive pericarditis. (A and B) Tissue Doppler index (TDI) measurements demonstrating elevated E′ in the medial aspect and reduced E′ in the lateral aspect (annulus reversus). (C) Septal wall movement towards the left ventricle (LV) during inspiration and towards the right ventricle (RV) during the expiration phase, suggestive of further reduced LV filling during the inspiration phase (septal bounce/paradoxical septal movement). (D) Mitral inflow variation >25% with respiration, indicating significant fluctuations in mitral blood flow with breathing.
