Constrictive pericarditis after SARS-CoV-2 vaccination: A case report

Coronavirus disease 2019 (COVID-19) and vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are associated with cardiovascular complications. Here, we report a case of right-sided heart failure caused by constrictive pericarditis that developed after the administration of messenger ribonucleic acid (mRNA) vaccine against SARS-CoV-2. A 70-year-old woman presented with body weight gain, peripheral edema, and dyspnea on effort, which developed over a period of 1 week after the second dose of vaccine. The jugular venous pressure was high with a prominent y descent (Friedreich's sign) and paradoxical increase on inspiration (Kussmaul's sign). The results of IgM and IgG testing specific to SARS-CoV-2 spike and nucleocapsid proteins indicated the presence of mRNA vaccine-induced antibody and were not suggestive of COVID-19 infection. Echocardiography showed pericardial thickening and septal bounce of the interventricular septum. Computed tomography (CT) also showed pericardial thickening compared with the results of the previous CT scan performed 4 months earlier. A diagnosis of right-sided heart failure due to constrictive pericarditis was confirmed on the basis of pressure analysis during cardiac catheterization.
