Abstract
Objective
To investigate the prenatal imaging characteristics, genetic characteristics and pregnancy outcome of fetuses with cardiac rhabdomyoma.
Study design
The prenatal ultrasound, cranial MRI imaging information and genetic test results of 35 fetuses prenatally diagnosed with cardiac rhabdomyoma were collected and retrospectively analyzed, and the pregnancy outcome was followed up.
Result
Cardiac rhabdomyomas mainly occurred in left ventricular wall and ventricular septum; cranial MRI imaging was found abnormal in 38.1% (8/21) of the fetuses; genetic test was found abnormal in 58.82% (10/17) of the fetuses; the fetus was born in 12 cases and the pregnancy was terminated in 23 cases.
Conclusion
TRIO whole exome sequencing (TrioWES) is recommended as the genetic test regime for cardiac rhabdomyoma. The comprehensive evaluation of prognosis of fetuses needs to consider the genetic results and whether the brain is involved; the prognosis of fetuses with simple cardiac rhabdomyoma is good.
