Persistent left superior vena cava accompanying congenital heart disease in children: Experience of a tertiary care center

Abstract

Increased awareness about the association of certain CHD with persistent left SVC and a careful echocardiographic examination can facilitate the diagnosis of persistent left SVC. In addition, precise prior diagnosis of persistent left SVC can prevent complications during surgery.

Persistent left superior vena cava: clinical importance and differential diagnoses

“…According to a study, while right atrial isomerism in patients with PLSVC is about 7%, left atrial isomerism is about 9% [14]. In another study, those prevalences are nearly 15% and 30%, respectively.…”

“…To date, many CA associated with PLSVC have been identified and grouped in different ways [1,14,15]. The subgroups of these anomalies are listed in Table 3.…”

“…Additionally, heterotaxy forms another disease spectrum associated with PLSVC and will be discussed under a separate title. In the literature, there is a wide range of information about the frequency of cardiac anomalies accompanying PLSVC [1,6,[14][15][16][17][18][19][20][21][22]. According to Lendzidan et al, the most common cardiac anomalies accompanying PLSVC are single ventricle, atrioventricular septal defect (AVSD), and tetralogy of Fallot (TOF).…”

“…Furthermore, there may be constriction or atresia of the CS ostium. In this case, the catheterization will be challenging and may result in serious complications, such as dangerous arrhythmias, cardiogenic shock, and tamponade [2,9,12,14].…”

Persistent left superior vena cava accompanying repaired tetralogy of Fallot: Does it pose a challenge for device implantation?

“…Persistent left superior vena cava was reported in 5.9% of tetralogy of Fallot patients. 6 In patients with persistent left superior vena cava, cardiac resynchronisation therapy device implantation can be performed successfully through the persistent left superior vena cava despite several anatomical difficulties. We also performed successful implantation with the methods mentioned above.…”
