From the Guidelines
A TAPS score of 2.0 is not a recognized standard medical term, and without additional context, it is unclear what this refers to in the context of Twin Anemia-Polycythemia Sequence (TAPS) diagnosis or management. The diagnosis of TAPS is typically made based on Doppler middle cerebral artery peak systolic velocity (MCA-PSV) values, with a suggested cutoff of >1.5 multiples of the median (MoM) for the donor twin and <1.0 MoM for the recipient twin, or an intertwin difference in MCA-PSV (D MCA-PSV) of >0.5 MoM 1.
TAPS Diagnosis Criteria
- MCA-PSV values >1.5 MoM and <1.0 MoM in donor and recipient twins, respectively
- D MCA-PSV >0.5 MoM
- Accompanying ultrasound findings such as discordant placental echogenicity, recipient twin cardiomegaly, or a “starry sky” appearance of the recipient liver
Given the information provided, it is not possible to determine if a "TAPS score of 2.0" is normal or abnormal without further context or clarification on what this score represents. In clinical practice, it is essential to rely on established diagnostic criteria and guidelines for TAPS, such as those recommended by the Society for Maternal-Fetal Medicine 1. If you are referring to a specific medical device, software, or treatment protocol, or if you have questions about TAPS diagnosis or management, consulting with a healthcare provider or a specialized fetal care center is recommended for personalized advice and care.
From the Research
TAPS Score Evaluation
- The provided studies do not directly address the question of whether a TAPS (Thrombocytopenia-Absent Radius Syndrome) score of 2.0 is considered normal, as they focus on Tricuspid Annular Plane Systolic Excursion (TAPSE) values in various patient populations 2, 3, 4, 5, 6.
- TAPSE is a measure of right ventricular longitudinal function, and its normal values vary across different age groups and populations, as reported in the studies 3, 4, 5, 6.
- For example, a study on healthy women over 70 years of age found a mean TAPSE value of 23.7 +/- 3.5 mm 4, while another study on pediatric patients reported TAPSE values ranging from 0.65 +/- 0.16 cm in healthy neonates to 1.79 +/- 0.33 cm in 18-year-old healthy adolescents 3.
- However, none of the studies provide information on TAPS scores or their interpretation, making it impossible to determine if a TAPS score of 2.0 is considered normal based on the available evidence.
