Fetal dextrocardia is a type of cardiac malposition where the major axis from base to apex points to the right side. This condition is usually associated with a wide spectrum of complex cardiac defects. As a result, dextrocardia is conceptually difficult to understand and diagnose on prenatal ultrasound. The advantage of four-dimensional sonography with spatiotemporal image correlation (STIC) is that this modality can facilitate fetal cardiac examination. A novel method known as fetal intelligent navigation echocardiography (FINE) allows automatic generation of nine standard fetal echocardiography views in normal hearts by applying intelligent navigation technology to STIC volume datasets...

Primary cardiac sarcomas are rare clinical entities with an incidence rate of 0.0001% in collected autopsy series and are regarded as very aggressive tumors. We herein describe a 21-year-old woman presenting with syncope, dyspnea, and abdominal distention. She suffered from massive ascites, plural effusion, and liver congestion demonstrated by abdominal sonography and chest X-ray. Transthoracic echocardiography revealed a heterogeneous solid mass located in the right atrium; therefore, the patient underwent radical surgical excision of the tumor and 3 cycles of adjuvant chemotherapy...

A retroesophageal left brachiocephalic vein is an extremely rare anomaly and has only been reported in 6 postnatal cases. Two prenatally diagnosed cases are reported. On the 3-vessel view, the vein appears as an aberrant vessel transversely coursing behind the aorta and trachea, which subsequently drains into the superior vena cava, giving rise to a U-shaped configuration. On color Doppler sonography, the U sign is bicolored. This anomaly should prompt the sonographer to carefully assess for other congenital heart defects, suggest consideration for genetic testing, and alert the cardiologist because it could affect central line procedures and cardiac interventions after delivery...

In sheep, there is a lack of information on the behaviour of hemodynamic indices and parameters of blood flow velocity of the uterine artery during pregnancy, making it impossible to determine the real meaning of the values found and their probable relevance in normal physiological or pathological states. The objective of the present study was to evaluate the blood flow velocity parameters and hemodynamic indices of the uterine artery in ewes (18) during pregnancy (33). Based on non-invasive colour Doppler sonography, we evaluated the peak systolic velocity (PS), end diastolic velocity (ED), time-averaged maximum and minimum velocity in a cardiac cycle (TAMAX and TAMEAN), pulsatility index (PI), resistance index (RI), systolic/diastolic ratio (S/D), heart rate (HR), arterial diameter (AD) and the blood flow volume (BFV)...
