چکیده

CONGENITAL cardiac defects involving the venous return to the heart and those affecting the partitioning of the atria should probably be considered as a group. The most commonly encountered and simplest to correct are defects in the interatrial septum of the ostium secundum type. Due to the lower resistance to emptying into the right ventricle from the two communicating atria, the shunt in such instances is left to right unless obstruction to flow is present in the tricuspid valve, in a hypoplastic right ventricle, in the pulmonary valve, or because of high pulmonary vascular resistance. Associated with defects in the interatrial septum various degrees of anomalous pulmonary venous drainage are also encountered. The simplest form involves drainage of the right pulmonary veins into the right atrium, with those from the left lung being normally inserted into the left atrium. Other variants include drainage of right-sided veins into the superior vena cava, and finally total anomalous pulmonary venous drainage into the superior vena caval system. Isolated anomalies of the venae cavae alone have also been described.1 The commonest is drainage of the superior vena cava into t:he coronary sinus or, more rarely, into the left atrium. This is generally associated with an interatrial defect but on occasions the superior vena cava is found to drain into the left atrium with an intact interatrial septum, resulting in a partial right-to-left shunt.2 Taussig 1 has described one instance of both

CONGENITAL HEART DISEASE Sinus venosus syndrome: atrial septal defect or anomalous venous connection? A multiplane transoesophageal approach

Objective: To discuss the anatomical features of sinus venosus atrial defect on the basis of a comprehensive transoesophageal echocardiography (TOE) examination and its relation to surgical data. Methods: 24 patients (13 men, 11 women, mean (SD) age 37 (17) years, range 17–73 years) with a posterior interatrial communication closely related to the entrance of the superior (SVC) or inferior vena...

Partial anomalous return of four pulmonary veins with intact interatrial septum defect. A rare case report.

We report on the rare case of partial anomalous return of four pulmonary veins in the right atrium and superior vena cava with intact interatrial septum in a five-year-old child. There were few symptoms in contrast with the left ventricular output dependent on the flow of the left upper lobe vein and from the lingula. Reduced compliance to the left led to a severe picture of pulmonary venocapil...
