The present series describes a group of adults with left-to-right shunts including partial anomalous pulmonary venous return (PAPVR) and/or an atrial septal defect (ASD) evaluated with ECG-gated 128-slice multidetector computed tomography (MDCT). PAPVR is defined as a left-to-right shunt where one or more, but not all, pulmonary veins drain into a systemic vein or the right atrium. PAPVR involv...

The Chiari network is described as a reticulated network of fibers connected to the Eustachian valve identified as the embryological remnant of the right valve of the sinus venosus. It is an incidental finding without any significant pathophysiological consequences. However, the presence of the Chiari network in the right atrium obliges the physician to differentiate from other right atrial pat...

Introduction Persistent left superior vena cava (PLSVC) is a congenital developmental abnormality of the sinus venosus with an incidence of 0.47% in patients undergoing cardiac implantable electronic devices. The 2 variants include a double superior vena cava (right and left SVC, with or without an innominate vein connecting the two) or a single left-sided SVC (without a right SVC), which may o...

Coronary artery disease causes acute myocardial infarction and heart failure. Identifying coronary vascular progenitors and their developmental program could inspire novel regenerative treatments for cardiac diseases. The developmental origins of the coronary vessels have been shrouded in mystery and debated for several decades. Recent identification of progenitors for coronary vessels within t...

Abstract A 21–year old male who underwent surgical closure of an isolated inferior type sinus venosus atrial septal defect (SV–ASD) at 6 years age was admitted to our institute for acute superior limb hypotonia and dysarthria, with brain computed tomography scan positive ischaemic event. The contrast transcranial Doppler (CTD) right–to–left shunt (RLS). transesophageal echocardiogram (TOE) reve...

The ductus venosus regulates the distribution of oxygen and placental nutrients by restricting the centralization of blood flow in fetal circulation. The ductus venosus is a small vein transmitting oxygen-rich blood from the umbilical vein to the fetal heart.. Increasing numbers of case reports are being published about ductus venosus agenesis with cardiac structural abnormalities, other malfor...
