A rare congenital anomaly of the great veins characterized by unilateral or bilateral complete absence of the superior vena cava (SVC). Unilateral agenesis is mainly asymptomatic (most of the time diagnosed incidentally) and patients usually have otherwise normal heart structure. Bilateral agenesis however is frequently associated with other congenital cardiac anomalies and/or conduction abnormalities (such as tetralogy of Fallot atrial septal defect) and typically present symptoms of SVC syndrome.

Advocacy Organizations

Collaborative Research Advocacy for Vascular Anomalies Network (CaRAVAN)

As the research-based umbrella organization for all vascular anomalies, we are on a mission to develop a unified network of patients and their families, advocates, researchers, and clinicians who influence research from initial concept and design to patient care delivery

Project FAVA

Project FAVA is a 501(c)(3) non-profit patient advocacy group that promotes awareness of fibro-adipose vascular anomalies, educates patients, their families, and the global community, and provides helpful resources to those with FAVA. Project FAVA also advances research to move the needle towards more effective and less invasive treatment options for FAVA patients.
