چکیده

BACKGROUND Persistent left superior vena cava (PLSVC) is a variant of systemic venous return which is observed in 0.3% of autopsies in the general population and in 4-8% of patients with congenital heart disease. AIMS To evaluate associated cardiac, extracardiac and chromosomal anomalies in prenatally diagnosed cases of PLSVC and to review their outcome. STUDY DESIGN Retrospective comparative study. METHODS The data of patients with a prenatal diagnosis of PLSVC between May 2008 and January 2013 were reviewed retrospectively. RESULTS Data of 31 cases were reviewed. Fifteen (48.4%) cases were associated with cardiac defects and 17 (54.8%) cases had associated extracardiac sonographic or postpartum findings. Two fetuses had karyotype anomalies. Outcome was significantly more favorable in cases not associated with cardiac defects in comparison to those associated with cardiac anomalies (84.6% vs. 33.3%, p=0.009). All cases with isolated PLSVC survived, while among the cases associated with extracardiac anomalies, with cardiac anomalies and with both extra-cardiac and cardiac anomalies, the survival rate was 75%, 50% and 22.2%, respectively. The most frequent group of cardiac anomalies associated with PLSVC was septal defects and VSD was the most common heart defect individually, being observed in nine fetuses. CONCLUSION Prenatally diagnosed PLSVC is associated with cardiac and extracardiac anomalies in the majority of cases. Outcome is significantly worse if PLSVC is associated with a cardiac defect, and the prognosis is excellent in isolated cases.

Clinical characteristics of prenatally diagnosed persistent left superior vena cava in low‐risk pregnancies

OBJECTIVE To determine the incidence and clinical characteristics of persistent left superior vena cava (PLSVC) among low-risk pregnancies. We have also compared electrocardiography (ECG) parameters of infants with PLSVC with those of normal controls. METHOD At our institute, fetal echocardiogram is routinely performed in the midtrimester. We retrospectively reviewed the records of prenatally...

A persistent left superior vena cava.

Persistent left superior vena cava is the most common form of anomalous venous drainage involving the superior vena cava, and represents persistence of the left horn of the embryonic sinus venosus, which normally involutes during normal development to become the coronary sinus. Almost always, a persistent left superior vena cava enters the right atrium through the orifice of an enlarged coronar...

Left Atrial Drainage of a Persistent Left Superior Vena Cava

Although the most common form of the persistent left superior vena cava anomaly is usually clinically silent and often discovered incidentally, the risk of developing cyanosis, heart failure, and embolic cerebrovascular events is high among cases where the anomaly causes a right to left shunt. A rare case of persistent left superior vena cava draining into the left atrium through the superior l...

Bedside confirmation of a persistent left superior vena cava based on aberrantly positioned central venous catheter on chest radiograph.

This is a report of incidental diagnosis of a persistent left superior vena cava (PLSVC) based on an abnormal positioning of central venous catheter seen on chest radiograph and an abnormal pressure waveform. Non-invasive bedside tests included venography with simultaneous chest radiograph and a transthoracic echocardiography with an agitated saline microbubble contrast. These tests led to the ...

Persistent left superior vena cava in atrial septal defect sinus venosus type: diagnosis with saline contrast echocardiography—a case series

Persistent Left Superior Vena Cava (PLSVC) should be suspected if we find dilatation of coronary sinus. Sophisticated imaging is not always available in each health care provider. Transthoracic echocardiography (TTE) with agitated saline injections through the left and right antecubital veins provides a simple, and inexpensive, but effective study for a rapid bedside diagnosis of PSLVC.
