BACKGROUND: Prosthetic mechanical valve endocarditis (PVE) can be manifested as early PVE (acquired perioperatively) and late PVE (resulting from infections unrelated to the valve operation). Causes of both are similar but are late PVE are more prone to less virulent microbes. PVE resulting with paravalvular abscess is confirmed through echocardiography (transthoracic or transesophageal), it results with a high mortality rate especially if it is not early recognized. CASE PRESENTATION: We are presenting a patient with heart failure symptoms caused by PVE after Pfizer-BioNTech coronavirus disease-2019 (COVID-19) m-RNA vaccination. CONCLUSION: The exact mechanism of myocarditis in young men who received the second dose of mRNA COVID-19 vaccine is not yet known. However, this is a rare complication and most people generally recover quickly requiring only supportive treatment. In contrast, the risk of developing myocarditis from the viral infection is much higher.
BACKGROUND: Peripartum cardiomyopathy (PPCM) is a rare and sometimes fatal systolic heart failure that affects women during late pregnancy or the early postpartum period. The risk factors contributing to this condition are advanced maternal age, multiparity, administration of tocolytic agents, underlying cardiac disease, iatrogenic volume overload, preeclampsia, and hypertension. In patients with gestational hypertension (GH) and other risk factors, close monitoring is mandatory during pregnancy as well as in the postpartum period. CASE REPORT: A 38-year-old patient previously treated for endometriosis, infertility, and GH was transferred from the clinic of gynecology due to diagnosed congestive heart failure. 5 days before admission, she gave birth to her first child. Before delivery, she was treated with tocolytic therapy. She received methyldopa due to GH which was abruptly discontinued after her delivery. Echocardiography on admission revealed moderately reduced left ventricular (LV) systolic function with an ejection fraction (EF) of 37% with dilated left ventricle (LV) and pulmonary artery hypertension secondary to LV failure. During hospitalization, the patient was with signs of volume overload, but with a good response on parenteral diuretic therapy. She was additionally treated with guideline-recommended heart failure therapy. The controlled echocardiography showed improvement of LV function with an EF of 42%. CONCLUSION: PPCM is a rare condition with high morbidity and mortality. An LVEF <30%, marked LV dilatation, LV end-diastolic diameter >6.0 cm, and RV involvement are associated with adverse outcomes. Although delivery of the fetus and the placenta triggers the resolution of symptoms and recovery to the nonpregnant state of various organisms, the contrary happens with blood pressure. Its peak time is 3–6 days after delivery. Hypertension medication must not be immediately terminated. Prolonged tocolytic therapy is a risk factor for PPCM due to causing decreased baroreflex sensitivity. Patients with risk factors should be closely monitored for eventual cardiac complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
