    Prenatal Ultrasound showing overdeveloped/thicker papillary muscle

    I recently had my 20 week ultrasound. The ultrasound tech informed the doctor the papillary muscle was more visible than normal. The doctor rescheduled an ultrasound for 3 weeks due to the baby's positioning they couldn't get a good overall view of the heart to make sure that there isn't any other issues. I am very worried. What does this mean?

    Hi:

    In general, as reported, the papillary muscles contract during the heart's pumping phase (systole) to prevent regurgitation (a back-flow of blood) into the atria (upper chamber/s). A hypertrophic or overdeveloped or thickened papillary muscle may/can affect this prevention aspect, which may/can then lead to other associated problems.

    Most important, communicate/interact well with your doctors.

    Hope all goes as well as possible with the pregnancy.

    Take care,
