Intramural cardiac masses were detected antenatally in three fetuses by echocardiography. The masses were initially thought to be rhabdomyomas. All three pregnancies were terminated and histology showed dystrophic calcification in all, with no evidence of tumour. Therefore, dystrophic calcification of the fetal myocardium may have a similar appearance to single or multiple rhabdomyomas. This sh...

Double aortic arch (DAA) is the most common congenital anomaly of the aortic arch system, in which the trachea and esophagus are completely encircled by connected segments of the aortic arch and its branches, often resulting in variable airway compression. We present a case of fetal DAA prenatally diagnosed by fetal echocardiography and clearly confirmed at autopsy. The autopsy visualization al...

Fetal arrhythmias are not uncommon. The diagnosis of a fetal arrhythmia is challenging and normally requires referral for a detailed fetal echocardiogram. The first step in the ultrasound evaluation should be distinguishing whether the arrhythmia is an irregular rhythm, a bradycardia, or a tachycardia. This can be done by evaluating the arrhythmia using simultaneous atrial and ventricular M-mod...
