La importancia de la ecocardiografía fetal en la detección y el manejo de las malformaciones cardiacas congénitas

[Isolated fetal pericardial effusion follow-up: Should we worry?]

INTRODUCTION AND OBJECTIVES

Fetal pericardial effusion appears in different pathologies such as hydrops fetalis, heart structural or rhythm alterations, however, it can be observed in isolation but an increase in its incidence has been observed in relation to the presence of severe pathologies.

METHODS

Analysis of all cases of IFPE detected in Aragon and assessed in a cardiological consultation for prenatal diagnosis of a tertiary hospital collected over 10years, as well as the evolution of the patients to the present.

RESULTS

A sample of 38 fetuses was obtained from 37 pregnant women diagnosed with DPFA with spontaneous resolution in 86.8%. Two abortions (voluntary interruptions after prenatal diagnosis of 22q13 deletion and primary infection by cytomegalovirus) and one spontaneous fetal death were recorded. Pathological alterations were observed in 10/38 newborns: 2patients with metabolic disease, 2patients with chromosomopathies, one patient with pulmonary hypoplasia and unilateral hydronephrosis, one patient with hypertrophic cardiomyopathy, and 4patients studied for alterations in psychomotor development and/or congenital ophthalmological or hearing disorders. The overall morbidity rate was 34.2% and death rate 15.7%. The detection of other ultrasound alterations and the alteration in the first trimester screening were significantly associated with the presence of pathology.

CONCLUSIONS

IFPE has been classically associated with a good prognosis, although it is sometimes related to clinical entities with high morbidity and mortality: more than a third of the patients in our sample are affected. An exhaustive pre- and posnatal follow-up of these cases is recommended in order to perform an early intervention.

Clinical analysis of prenatal ultrasound diagnosis of fetal cardiovascular malformations in the first and second trimesters of pregnancy: A CARE-compliant article

Fetal cardiovascular malformations is widely focused and screened, but the accuracy of screening is not satisfactory. In this study, we compared the types of congenital heart malformation, accompanying diseases and fetal outcomes in the first and second trimesters of pregnancy to clarify the advantage of early screening.From January 2013 to June 2018, 230 fetuses were diagnosed with congenital heart malformations using ultrasound method in Qilu Hospital of Shandong University, and divided into 2 groups:the first trimester fetuses (group A) and the second trimester fetuses (group B). In addition, we collected and organized medical data of 347 cases diagnosed with congenital heart disease during 1998 to 2005 (group C). We compared the spectrum of congenital heart disease, associated comorbidities and outcome of fetuses diagnosed with congenital heart disease.There were differences in the types and incidence of cardiac malformations between the first and second trimesters of pregnancy. The number of cases of non-cardiac malformation, congenital heart disease with single ventricular circulation, fetal intrauterine death and premature pregnancy termination was significantly lower in the late stage (group A and group B) than that in the early stage (group C). More patients were screened for trisomy 21, 18, 13 syndromes and Turner syndrome in group A than group B (P <.001). More fetuses with a 22q11 deletion were screened in group B than group C.Early pregnancy screening using ultrasound diagnosis is very important for fetuses with congenital heart disease.
