Evaluation of Fetal Heart Using Fetal Heart Quantification (fetalHQ) Technique in an Indian Cohort.

OBJECTIVE: To evaluate the intra- and interobserver reproducibility of parameters used to determine cardiac morphometry and deformation using FetalHQ in Indian population. METHODOLOGY: Two operators blinded to each other performed FetalHQ analysis independently on 35 normal fetuses of gestational age between 18 + 0 and 37 + 0 weeks and days. Intra- and interobserver correlation coefficient and limits of agreement were ascertained for parameters obtained from HQ analysis. RESULTS: Excellent reproducibility (ICC > 0.9) was observed for global morphometric parameters. Ejection fraction, stroke volume, stroke volume/kg demonstrated excellent reliability (ICC > 0.9), cardiac output, fractional area change showed a lower correlation (ICC < 0.8), and right and left ventricular global strain showed no correlation. Twenty-four segment sphericity index of left ventricle (LV) and right ventricle (RV) showed low to moderate correlation (LV-ICC 0.48-0.79; RV-ICC 0.43-0.82). Fractional shortening (FS) showed poor intraobserver reliability in RV. CONCLUSION: FetalHQ provides reliable estimates of the global cardiac morphometry but not for global cardiac strain. Regional transverse contractility represented by FS has poor correlation in right ventricle, especially in the apical region, possibly due to moderator band. Nevertheless, it is a promising tool which requires technical advancements and validation to improve its accuracy and reliability.

Bright and enlarged fetal kidneys: One phenotype different genotypes, and counseling dilemmas.

INTRODUCTION: In the present study we describe atypical cases with bright and enlarged fetal kidneys identified on fetal ultrasound with different genetic etiologies. METHODS: Exome sequencing was undertaken after prenatal counseling and after the initial diagnosis of enlarged fetal kidneys was made on ultrasound for four cases and the results were then correlated. RESULTS: In the present study we identified underlying variants in ACE, ETFA, PKD1, and MKS1 gene where the atypical presentation of fetal kidneys was noted either as a part of spectrum of syndrome or alone. CONCLUSIONS: In the era of exome sequencing, targeted gene sequencing is getting replaced and for better. However not all answers are direct, and sometimes the variant categorization is dependent on the acumen and agreement of all those involved in the process. It includes those involved the diagnostic as well those catering to the patients. It is very important to be updated on the relevance of multiple gene in causing similar phenotypes particularly in the prenatal context were coming up with a timely diagnosis is very important for any sort of intervention.

Anti-G with Concomitant Anti-D and Anti-C in a Pre-natal Patient, in India: Multi-disciplinary Approach to Diagnosis and Management.

'G' antigen belongs to the Rh family and it was first described by Allen and Tippet in 1958. Various anti-D, anti-C, and anti-G antibody combinations can be found in patients. Ruling out the presence of anti-D is important for administering RhIg prophylaxis in RhD-negative pregnant women to prevent hemolytic disease of fetus and newborn (HDFN). RhIg prophylaxis is not indicated in the presence of an anti-D antibody. Time-to-time monitoring and follow-up of cases of RhD-negative pregnant women with a multi-disciplinary approach including an obstetrician, neonatologist, and transfusion medicine specialist helps diagnose, manage, and monitor HDFN in such cases. This case report emphasizes the need for proper antibody identification (anti-G) and managing HDFN (with intrauterine transfusions and exchange transfusion) during the perinatal period.

First Trimester Diagnosis of Body Stalk Anomaly Confirmed Postnatally.

Body stalk anomaly, with a prevalence of 0.12 in 10,000 births, occurs when abdominal organs develop outside the abdominal cavity while remaining attached to the placenta in the fetus. This article relates to a rare case of body stalk anomaly detected in the first trimester of pregnancy. The images presented are characteristic to the anomaly. A postnatal evaluation confirmed the findings and helped in comprehensive counseling of the patient.

Universal Screening for SARS-CoV-2 in Asymptomatic Pregnant Women: A Multi-center Experience.

BACKGROUND: Novel coronavirus (SARS-CoV-2) is responsible for the current global pandemic and understandably, Obstetrics is not spared. Private maternity hospitals have a unique challenge of reassuring unaffected patients of uneventful delivery with the lowest possible rate of coronavirus infection while consequently offering compassionate and state of art services to women who turn out to be positive for SARS-CoV-2. This has led to a routine SARS-CoV-2 testing of all patients before admission in many of the private hospitals in India. The current study was undertaken to determine the incidence of SARS-COV-2 among asymptomatic pregnant women and to ascertain the utility of universal screening in these women. METHODOLOGY: A retrospective observational multi-center study was conducted over a period of approximately 5 months (1-May-2020 to 10-September-2020) in a chain of privately run maternity hospitals with presence in multiple cities across India. All asymptomatic pregnant women were tested for SARS-CoV-2 prior to elective/emergency hospital admission. RESULTS: Among 4158 women tested, 54 (1.3%) were positive for SARS-CoV-2 and intra partum and postnatal period was uneventful for all of them. CONCLUSION: Universal screening should be continued as preferred approach to ensure low anxiety levels of delivering women and safety of frontline workers. Further, universal screening helps avoid emergence of maternity centers as virus clusters by effective isolation of identified positive cases and minimizing points of contact.
