Objective: Our aim is to assess the knowledge, attitude, and behaviors of pregnant women about COVID-19. Material and Method: This cross-sectional survey study was performed on pregnant women in their second and third trimester between the November-December 2020. The participants completed a questionnaire consisting of 5 parts. Demographic data of pregnant women, their knowledge, attitude, and risk perceptions toward COVID-19, their practices and worries about COVID-19, and what they knew about pregnancy were assessed. The answers were calculated as a percentile and mean. Results: A total of 1011 participants were included in the statistical analysis. Of the participants, 98.5% knew that COVID-19 was transmitted through close contact. Of the participants, 47.5% extremely trusted healthcare workers in fighting against the COVID-19 pandemic. Affection and respect for healthcare workers during the pandemic increased by 89.1% of the participants. Of the participants, 50.6% were intending to decrease their antenatal visits during the COVID-19 pandemic and 39.4% thought that their baby may be infected after birth. Conclusion: The measures taken can be applied with high awareness of COVID-19. Sufficient training, in that case, can be done through communication routes such as information and public service announcements.

Aim: We aimed to examine fetal cardiac output (CO) in patients who recovered from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Materials: This prospective study included 48 pregnant women recovered from SARS-CoV-2 infection and 50 control cases. SARS-CoV-2 infection was diagnosed by polymerase chain reaction (PCR) test in patients. Fetal echocardiographic evaluations were performed at 24-37 weeks of gestation in pregnant women who recovered from the infection and control group. Results: The median value of ultrasound evaluation was 34 (2.6) weeks of gestation in the recovery from the SARS-CoV-2 infection (RSI) group, and 32 (7.6) weeks in the control group (p=0.565). Left cardiac output (LCO) z score was significantly lower in the RSI group than the control group (p=0,041). LCO and combine cardiac output (CCO) z score were significantly lower in the severe disease group than mild, moderate disease groups, and controls (p=0,019 and p=0,013). CCO (mL/min/kg) was decreased in the severe disease group when compared with control and mild disease groups (p=0,044). Fetal distress, preterm delivery rate, and neonatal intensive care unit (NICU) admission were found to be higher in the severe disease group compared to the control group (p=0,010, p=0,009, and p<0,001 respectively). Conclusion: In the present study, fetal cardiac output in pregnant women with recovery from SARS-CoV-2 infection was found significantly decreased, especially in whom had severe diseases. Placental dysfunction and inflammatory cytokines might cause fetal cardiac changes. Further studies could be clarified on the impact of SARS-CoV-2 infection on fetal cardiac function.
