case_images: Mother's electrocardiogram (ECG), A-type, B-type natriuretic peptide, and fetal data changes . Panel A: There are no changes in ECG before and after pregnancy.. Panel B: Changes of A-type and B-type natriuretic peptide during pregnancy.. Panel C: Changes of mother's body weight (BW), fetal femur length (FL), biparietal diameter (BPD), and estimated weight (EFW) during pregnancy.

case_images: Augmented positive P waves in I II V2-6 and negative P waves in aVR in electrocardiography (ECG) may indicate a large right atrium (Figure 1A). Neither the ECG findings nor the diameter of the vena cava changed (Figure 1A). BNP levels increased as the pregnancy progressed (Figure 1B). The fetus grew well (Figure 1C).
case_images: Right heart changes before and after pregnancy in magnetic resonance images (MRI) and transthoracic echocardiography (TTE). LV: left ventricle RA: right atrium RV: right ventricle. Panel A: before pregnancy MRI image   Panel B: after pregnancy MRI image . Panel C: before pregnancy TTE image     Panel D: after pregnancy TTE image

case_images: TTE revealed that the right atrium enlarged after the baby was born (Figure 2). TTE showed that the RV area was diastole 10.9/systole 8.8cm2 in before pregnancy (Figure 2C) and was diastole 11.5/ systole 8.3 cm2 in after cesarean delivery (Figure 2D).
