“…When BSVC is strictly isolated, a genetic anomaly is usually absent. Conversely, single LSVC is usually an isolated antenatal finding 7–10,12 , as seen in this series. Genetic abnormalities are rarely reported in single LSVC 11 , and such an abnormality was seen in only one case in our series.…”

“…The aortic arch was normal in all fetuses. Only 13 cases of single LSVC have previously been reported prenatally, which were isolated [7][8][9][10]12 , with the exception of one case that was associated with VAC-TERL 11 . However, in postnatal series of single LSVC, there is a stronger association with CHD (46-100%) [4][5][6] , and some cases also had rhythm (25%) or chromosomal abnormalities, including trisomy 21 and trisomy 18 (7%) 5 .…”

“…This diagnosis is usually reported as an incidental finding during invasive procedures or autopsy series, with a reported incidence of 0.05% 4 , 5 , 6 . Only a few, isolated cases of antenatal diagnosis of single LSVC have been reported to date 7 , 8 , 9 , 10 , 11 , 12 .…”

Objectives: To describe the associated cardiac and extracardiac findings and estimate the prevalence of single left superior vena cava (LSVC) among fetuses referred for fetal echocardiography. Methods: This is a retrospective case series study of fetuses diagnosed with situs solitus and single LSVC at the Brompton Centre for Fetal Cardiology, from October 2006 to December 2020. Prenatal and postnatal outcome data were collected. Prenatal diagnosis was based on abnormal vessel alignment at the 3-vessel view (3VV) and/or 3-vessel and trachea view (3VT), showing a vessel to the left of the pulmonary artery, the LSVC, and absence of the usual vessel to the right of the ascending aorta, the right superior vena cava (RSVC), and further visualisation of the LSVC draining to the coronary sinus.Results: Amongst 19,968 fetal echocardiograms, 34 cases were identified (prevalence 0.17%).There were 32 livebirths, 1 lost to follow up and one fetal demise. Single LSVC was isolated in most cases. No major CHD was identified. One fetus showed mild isthmus hypoplasia, with no aortic coarctation postnatally. Two fetuses had umbilical vessel abnormalities. Genetic abnormality was found in one case. Conclusions:Antenatal diagnosis of single LSVC in situs solitus is usually a benign isolated finding. Nevertheless, investigation of other cardiac, extracardiac and genetic disorders should be considered.

“…Prenatal detection of a single LSVC has been rare, and previous publications are limited to case reports of 1-5 patients [14,17]. O ¨zsu ¨rmeli reported a series of 32 cases of prenatal diagnosis of persistent LSVC, all but one had bilateral SVCs [18].…”

A persistent LSVC with an absent right superior vena cava (RSVC) is unusual, encountered in about 10% of patients with persistent LSVC. We present 14 patients with a prenatal diagnosis of single LSVC and situs solitus, including prenatal findings and information on medium-term follow-up. We identified patients with situs solitus and a persistent LSVC born between March 2004 and March 2020, which had been diagnosed prenatally between December 2003 and November 2019. From this cohort, we identified those with absent RSVC. In the population of women undergoing fetal echocardiography, the prevalence of persistent LSVC in situs solitus was 0.43% (84/19,712). For the 84 identified patients and for the entire population respectively, 14/84 (17%) and 14/19,712 (0.07%) had a single LSVC (absent RSVC). Of 14 patients with a single LSVC, 8 (57%) were male. For the 84 identified patients and for the entire population respectively, 70/84 (83%) and 70/19,712 (0.36%) had bilateral SVCs. For a single LSVC (absent RSVC) and situs solitus, the majority had no associated cardiac, extracardiac, or syndromic abnormalities.

La presencia de la vena cava superior izquierda persistente (VCSIP) tiene una incidencia del 0.3 al 0.5% en la población general. En la mayoría de los casos, la vena cava superior derecha (VCSD) está presente, sin embargo, en raras ocasiones ésta puede estar ausente. Nuestro caso pretende mostrar la importancia de la evaluación ecocardiográfica inicial en el diagnóstico diferencial del seno coronario dilatado y la sospecha de malformaciones congénitas asociadas.
