As an intra-cardiac right-to-left shunt, the patent foramen ovale (PFO) has gained attention over the last two decades because of its potential pathological importance in a number of disease processes including stroke, peripheral embolism, systemic oxygen desaturation (i.e. hypoxaemia) and migraine headaches. Percutaneous PFO closure, using a double-umbrella Clamshell device (Bard, USCI,…

Patent foramen ovale (PFO) is a common abnormality, occurring in 20–34% of the population.1 In the majority of infants, closure of the foramen ovale occurs soon after birth, as negative intrathoracic pressure associated with the first breaths closes the PFO. In some cases, the primum and secundum atrial septa fail to fuse and closure remains incomplete. There is continuing communication between…

Patent foramen ovale (PFO) is common and occurs in 20–34% of the population.1 In most infants, the foramen ovale closes soon after birth, with a reduction in pulmonary vascular resistance raising the left atrial pressure above that of the right atrium during the first few breaths, closing the septum. In a significant proportion of individuals, the primum and secundum atrial septa do not fuse, and…

The foramen ovale is an integral component of the fetal circulation, responsible for facilitating the flow of placental pre-xygenated venous blood from the right atrium to the left, thereby circumventing the quiescent developing lungs. Physiological closure is usually achieved after birth when pulmonary vascular resistance and right heart pressures reduce, resulting in the left atrial pressure…

Cerebrovascular events are associated with high rates of morbidity and mortality and are considered the global second leading cause of death.1 The majority of strokes are ischemic, although the etiology remains unknown in a considerable number of patients,2 commonly referred to as “non-defined” or “cryptogenic.”3 Data from epidemiologic studies point towards a relevant association between the…

The morphology and function of the inter-atrial septum changes dramatically from the period of in utero development until its role in normal adult cardiac physiology is established. Its anatomical construction is complex and involves the eventual formation of a septum secundum, fossa ovalis and septum primum. In utero a mixture of deoxygenated blood from the foetus and oxygenated blood from the…
