ABSTRACT
Introduction: Covid-19 infection, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a leading cause of morbidity and mortality worldwide. Myocarditis or pericarditis is a common clinical manifestation reported during the acute illness of Covid-19 infection. However, it is rarely reported during the recovery period or as part of post-Covid 19 conditions. We are reporting a case of a pregnant lady presented with post-covid 19 myocarditis with RVOT VT. Case presentation: A 44-year-old lady, Gravida 7 Para 6, presented to us at 32 weeks POA with the complaint of palpitation of 1 week, which was more frequent and persistent on the day of admission, associated with a presyncopal attack. Otherwise denied chest pain, fever or joint pain, or swelling. She had a history of Covid 19 infection 1 month prior to the onset of palpitation and had received 2 doses of SINOVAC vaccination. Upon presentation in the emergency department, she was tachycardic;however, her BP was normotensive and afebrile. Blood Investigations were unremarkable. ECG showed short run VT which self-reverted to sinus rhythm. Upon admission to CCU, she had multiple episodes of stable VT, which self-reverted to sinus rhythm. Echo showed EF 60% with no regional wall motion abnormality or valvular lesion. Cardiac MRI reported LV function of 46% with suspicion of fibrosis at the mid-septal wall. While in the ward, she had polyarthralgia, which improved with hydrocortisone. Blood investigation showed elevated inflammatory markers;otherwise, blood culture and ASOT were negative. Further investigations sent for connective tissue disease showed a positive result for ANA and ENA;however, it does not fulfill the SLICC criteria. Hence, we diagnosed her post covid 19 related myocarditis. She is currently generally asymptomatic with low-dose prednisolone and has been closely monitored for manifestation that may represent SLE. Discussion(s): The incidence of myocarditis in Covid-19 infection is 0.12%, which is 2-3 folder higher than non- covid 19 infection pneumonia;however, the prevalence in post covid infection is still unknown. It has been demonstrated that infectious causes are a significant initiating event in the pathophysiology of autoimmune disorders. A number of processes, including angiotensin-converting enzyme maladaptation, hypercoagulability, microvascular damage, and direct viral toxicity, may cause the etiology of post Covid-19 infection. Conclusion(s): Myocarditis in post Covid-19 condition is an uncommon but still possible condition that needs to be considered. It can be CTD mimickers;however, the symptoms must be closely monitored.Copyright © 2023
