Our encounter with left superior vena cava

Failing to learn from the past: Report of a patient with twice failed central venous cannulation

“…[ 3 ] Most common associations include atrial septal defect, ventricular septal defect, endocardial cushion defect, tetralogy of Fallot and cor- triatriatum. [ 4 ] Clinical implications of PLSVC include:[ 5 ]…”

“… Challenges during central venous cannulation, transvenous pacing and pulmonary artery catheter insertion through the left internal jugular or subclavian vein Cardiac conduction defects and cardiac arrhythmias, mainly atrial fibrillation, owing to involvement of atrioventricular node or bundle of His by a dilated coronary sinus Atypical drainage into the left atrium may result in systemic air embolism during cannulation due to direct entry of air into the systemic circulation Difficult cavopulmonary anastomosis PLSVC is considered a relative contraindication for retrograde cardioplegia as it can lead to steal in the systemic venous circulation during retrograde cardioplegia[ 5 ] Rarely obstruction to left ventricular inflow by enlarged dilated coronary sinus. …”
