AI Article Synopsis
- Persistent left superior vena cava (PLSVC) is a rare congenital condition affecting about 0.3% of the population, usually draining into the right atrium without complications.
- In approximately 10% of PLSVC cases, it drains into the left atrium, leading to a right-to-left shunt that may cause health issues.
- A 60-year-old male patient with PLSVC draining into the left atrium experienced breathing difficulties and desaturation when changing body positions after a specific medical procedure, highlighting the need to consider this anomaly in similar cases.
Article Abstract
Persistent left superior vena cava (PLSVC) is a rare congenital anomaly whose prevalence is 0.3 % of general population. The majority of PLSVC drain into right atrium (RA) through the coronary sinus without clinical harm. However, in about 10 % of patients with PLSVC, it drains into left atrium (LA) causing right-to-left shunt. Here, we present a 60-year-old male patient with a PLSVC draining into LA, who developed dyspnea and desaturation depending on the body position after trans-catheter coil embolization of coronary to pulmonary artery fistulas. PLSVC draining into LA should be included in the differential diagnosis of positional desaturation.
