Persistent Left Superior Vena Cava
Persistent left superior vena cava (PLSVC) is a congenital venous anomaly occurring in 0.3% of patients with normal hearts and in 4.5% of patients with congenital heart disease. Regression of a caudal right superior cardinal vein during embryological development can lead to PLSVC with an absent right superior vena cava (RSVC), occurring in 0.07-0.15% of patients. This anomaly is usually asymptomatic and often detected when patients undergo CVC placement or work up for cardiac surgery. Our patient presented for aortic valve replacement, where antegrade cardioplegia was provided. We will discuss the variations of PLSVC, it’s associated hemodynamic derangements, and management techniques.
