[Case of peripartum cardiomyopathy misdiagnosed as pulmonary changes due to COVID-19].

A 37-year-old female patient was admitted 16 days after delivery in a hospital for infectious diseases with cough, shortness of breath, and infiltrative changes in the lungs that were interpreted as viral pneumonia. Considering the failure of therapy and the history, peripartum cardiomyopathy was suspected. Examination revealed a decrease in left ventricular ejection fraction to 30 %, ultrasonic signs of lung congestion and bilateral hydrothorax. The patient was diagnosed with peripartum cardiomyopathy accompanied by functional class 4 heart failure. A specific feature of this case was fast positive dynamics with complete regression of the clinical picture of congestion and improvement of the left ventricular myocardial function associated with the treatment.

Aortic Dissection and COVID-19 Pneumonia in a Pregnant Woman at 34 Weeks of Gestation.

Between 0.1% and 0.3% of all aortic dissections occur during pregnancy. Arterial hypertension, connective tissue disorders, and congenital cardiovascular anomalies-including bicuspid aortic valves-are well-known risk factors. The causality between pregnancy and aortic dissection is unclear, but there have been some observations that COVID-19 illness may increase the risk. This report describes a pregnant woman at 34 weeks of gestation who had a bicuspid aortic valve and experienced an acute aortic dissection while ill with COVID-19 pneumonia. Computed tomography confirmed a type A aortic dissection and bilateral patchy pulmonary opacities. Cesarean delivery was performed, followed by replacement of the aortic valve with a mechanical aortic prosthesis and reconstruction of the ascending aorta and hemiarch. The intraoperative course was uneventful, and the patient was successfully weaned from mechanical ventilation after 51 hours. COVID-19 during pregnancy seems to increase the risk for aortic dissection, although there is no evidence base for an association. Because guidelines for diagnosis and treatment in such complex cases are lacking, care from a multidisciplinary team is crucial for successful outcomes.

Two cases of coronavirus 2019-related cardiomyopathy in pregnancy.

At our institution, 2 of the initial 7 pregnant patients with confirmed coronavirus disease 2019 severe infection (28.6%; 95% CI, 8.2%-64.1%) developed cardiac dysfunction with moderately reduced left ventricular ejection fractions of 40%-45% and hypokinesis. Viral myocarditis and cardiomyopathy have also been reported in nonpregnant coronavirus disease 2019 patients. A case series of nonpregnant patients with coronavirus disease 2019 found that 33% of those in intensive care developed cardiomyopathy. More data are needed to ascertain the incidence of cardiomyopathy from coronavirus disease 2019 in pregnancy, in all pregnant women with coronavirus disease 2019, and those with severe disease (eg, pneumonia). We suggest an echocardiogram in pregnant women with coronavirus disease 2019 pneumonia, in particular those necessitating oxygen, or those who are critically ill, and we recommend the use of handheld, point-of-care devices where possible to minimize contamination of staff and traditional large echocardiogram machines.

Peripartum cardiomyopathy in a COVID-19-infected woman: differential diagnosis with acute myocarditis-A case report from a Hub Institution during the COVID-19 outbreak.

We report the case of a healthy 35-year-old woman who had experienced a flu-like syndrome during the week before childbirth and heart failure symptoms 10 days before the current hospitalization and presented to our emergency department with clinical signs of congestive heart failure, echocardiographic evidence of a severely dilated and hypokinetic heart, laboratory evidence of SARS-CoV-2 disease, and radiologic findings consistent with both virus-related pneumonia and heart failure. Early cardiac magnetic resonance was crucial for the diagnosis of postpartum cardiomyopathy and for the exclusion of virus-related myocarditis, allowing us to decide on a prudent and supportive clinical approach.
