Statement on the Measurement of Fetal Heart Rate

The AIUM released a Statement on Measurement of Fetal Heart Rate last month which can be found on their website, www.aium.org/publications/statements.aspx. As a result, because our ultrasound practice is accreditated by the AIUM, we changed our policy and only document the fetal heart rate by M-mode. I have had only a few instances where the M-mode was not successful due to maternal morbid obesity but in the majority of cases M-mode…See More

Lisa M. Allen replied to Juan Carlos pari salas's discussion 'VENTRICLES' in the group Obstetric Ultrasound Community

Two lateral ventrcles are noted with choroid plexus noted in each ventricle. In the second image, it appears that the CSP is present and the actual size of the atria of the cerebral lateral ventricle does not appear to be dilated. Did you…

Lisa M. Allen replied to Lisa M. Allen's discussion 'muscular ventricular septal defects' in the group Fetal Echocardiography Community

Thank you for your comments. As a follow-up, two of the cases that we had detected (that did receive a confirmatory formal prenatal fetal echo) have since delivered. One was a small apical muscular VSD and the other a large mid muscular VSD. Both…

David N Jackson replied to Lisa M. Allen's discussion 'muscular ventricular septal defects' in the group Fetal Echocardiography Community

Lisa, Once again you have been at the vanguard of stimulating an important discussion. You asked several key questions: 1) Is a small, isolated VSD significant? 2) What is the sensitivity of an…

Lisa M. Allen replied to Lisa M. Allen's discussion 'Fetal thymus' in the group Fetal Echocardiography Community

Thanks Joe, You are absolutely right, the thymus is difficult to delineate prenatally and does take some practice to image.

Joe Kreeger replied to Lisa M. Allen's discussion 'Fetal thymus' in the group Fetal Echocardiography Community

Lisa, Thanks for such beautiful examples and great articles. I think that this is a very helpful tip for sonographers to employ when findings are consistent with a conotruncal defect. The thymus gland (or lack thereof) is very…

Fetal thymus

I just posted this same information on the obstetric community. Here is a nice example of the fetal thymus gland at 33 weeks of gestation. This gland sits anterior and superior to the heart between the sternum and three vessel view. The thymus can be hypoplastic or absent with VCF (22q deletion syndrome associated with conotruncal abnormalities of the heart). If you see an anomaly of the outlfow tracts, try to assess the size of the thymus. The following articles may be helpful, many more were…See More

REGINA RACHAEL replied to Lisa M. Allen's discussion 'Single dose ultrasound couplant' in the group Obstetric Ultrasound Community

Thank You, Lisa Great info, as always from you. I just wrote to the company to get some samples. My concern is cost effectiveness, but we also must prioritize patient safety. I must admit, squeezing those gell bottles and right…

Dr MM Nurus shafi replied to Lisa M. Allen's discussion 'Single dose ultrasound couplant' in the group Obstetric Ultrasound Community

Single dose gel is a very nice concept. It will be decades before we people will use here. Specialized centres should use it. Certainly it will be costly. People here even do not like the use of couplant spread on the bodies. Once my…

Yes I am, and I was instructed by Dale to return of the volunters back before 12:00 am this past weekend in DC, in privious meetings some of the volunter's return later than 12:00 am.

Well regarding my day Monday call after returning from San Diego was not easy. I had a chance to see your case and I think the nuchal edema and neck lymphadema are all related to your cardiac anomaly unless there is another chromosomal disorder associated with suppression calcium of the nasal bone other than DNA issues with chromosome 21.

Despite the confounding co-variables, IVF has been demonstrated in multiple studies to be a risk factor for CHD. As a result, I consider IVF to be a reasonable indication for detailed fetal echocardiography. I hope this answers your question!
