“…The association between PLSVC and aberrant venous drainages has also been reported, consisting of right subclavian vein draining into the left superior vena cava (13). PLSVC can also be associated with left subclavian vein stenosis and absence of the right superior vena cava (14). Moreover, cases in which PLSVC drains into the left superior pulmonary vein and the presence of usual signs of a right-to-left shunt have been also reported (15).…”

Background/Aim: The presence of the superior left vena cava represents a rare anomaly of the thoracic venous system. Case Report: An asymptomatic case of this type of anomaly, discovered as an accident during investigations for a different pathology (superior left pulmonary lobe tumor), is presented. A 56-year-old, heavy smoker was admitted in our clinic with a tumoral mass in the left superior pulmonary lobe discovered during a routine chest x-ray. Physical and clinical examination was normal. However, transthoracic echography noted a coronary sinus enlargement, which led to the suspicion of a thoracic venous anomaly. Contrast chest computed tomography pointed out a venous anomaly at the level of the left hemithorax originating from the cervical region, crossing the aortic arch and draining in the coronary sinus. During the examination, contrast substance was not detected in the right superior vena cava, either early or late during the computed tomography. During surgery the presence of a persistent left superior vena cava was observed, coming from the cervical region, crossing lateral to the aortic arch and draining in the coronary sinus. Conclusion: The presence of an enlarged coronary sinus should warn the surgeon about the possibility of a thoracic venous anomaly. Identifying a persistent left superior vena cava is important due to its clinical implications, especially during certain procedures such as mounting central venous lines, cardiac cannulation or implantation of cardiac stimulators. 935

“…The prevalence of the latter is difficult to assess since the available information comes mainly from limited series derived from patients with other congenital abnormalities [14,15]. However, from the available data, its occurrence can be estimated to be at most one-fifth to one-third of LSVC cases [3,5,16].…”

Persistent left superior vena cava (PLSVC) is the most common variant of abnormal venous return to the heart. While usually asymptomatic, it is known to complicate transvenous cardiac procedures, such as implantation of cardiac electronic devices and ablations. PLSVC can present with or without the concomitant absence of right superior vena cava (RSVC). Depending on the operator's preference, implantation of permanent cardiac pacemakers (PPMs) may be performed from the left or right side. As most often the PLSVC is only identified at the time of intervention, it follows that the variant with the absence of RSVC can be diagnosed in practice only when implanting from the right side. For this reason, the true prevalence of this variant is largely unknown because most published cases of cardiac device implantations in patients with PLSVC have been performed from the left side. We present a short 3-case series of PPM implantations in a tertiary center from the right side in patients with PLSVC and absent RSVC. We found that the use of a standard curve for ventricular lead septal placement and a wide C-curve for right atrial lead placement in these patients was a feasible technique with good outcomes.
