Background
The left superior vena cava (LSVC) is a common anomaly of the systemic veins. It usually drains to the coronary sinus. Its prevalence in the general population is 0.1-0.5 % . It is more in patients with congenital heart disease (CHD) (3-5 % ).The importance of detecting LSVC prior to cardiac surgery is paramount for the systemic veins canulations during cardiac surgery. Failure to detect its presence before surgery may lead to some difficulties and prolongation of the surgical operation.
Objective
To estimate the prevalence of LSVC in patients with or without congenital heart disease in our patient population.
Methods
All echocardiographic studies of patients seen at our institute between December 2010 and October 2011 were reviewed for presence of persistent LSVC. The demographic data, CHD diagnosis, presence of LSVC and associated diseases or syndromes were documented. The incomplete studies were excluded from the analysis.
Results
The total numbers of patients were 1802. Patients with no CHD made 47 % and those with CHD were 53 % of the referrals. The prevalence of LSVC in the healthy children was 0.9 % and in those with CHD was 7 % . Down syndrome was commonest associated syndromes. The most common cardiac lesion associated with LSVC was complete atrioventricular septal defect. In all patients the LSVC drained into the coronary sinus except in one where it drains to left atrium.
Conclusion
The prevalence of LSVC in the current population is higher than reported in the literature. Down¡¯s syndrome has higher prevalence, especially those with atrioventricular septal defect.
