Agenesia de vena cava superior derecha y persistencia de vena cava superior izquierda

Abstract

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.

Right Superior Vena Cava Agenesis and Persistent Left Superior Vena Cava: Literature Review and Case Report

“…The association with agenesis of the RSVC is exceedingly rare (3,4). Martinez-Villar reports 150 pediatric patients (0-18 years old) with LSVC, with only 12 patients (8%) having absence of the RSVC, among whom 58% (7 patients) had an association with congenital malformation and the remaining 42% had structurally normal hearts (López et al, 2019).During a routine dissection intended for undergraduate students, an observation was made of a persistent left superior vena cava (LSVC), accompanied by variations in the anterior cardiac vein and the right septal pouch (RSP), within the heart ofan approximately 48-year-old male cadaver.This highlights that this finding may be incidental. The persistent LSVC was found to drain into the right atrium via the coronary sinus.…”

“…Imaging modalities such as computed tomography (CT) angiography, magnetic resonance imaging (MRI), and echocardiography play a crucial role in diagnosing and characterizing venous anomalies. These techniques provide detailed anatomical information, allowing for accurate identification of RSVC agenesis, PLSVC, and associated cardiovascular abnormalities (López et al, 2019) (Mori et al, 2022).…”
