Atrial septal abnormalities are common congenital lesions remaining asymptomatic until adulthood in a great number of patients. The most frequent atrial septal defects in adults are ostium secundum atrial septal defect (ASD) and patent foramen ovale (PFO), both approachable by transcatheter closure using device implantation. The first non-surgical ASD closure was performed in 1975 by Mills and… View more

Percutaneous catheter-based structural heart disease procedures are a rapidly growing area of interventional cardiology, and represent a valuable option for cardiac patients with comorbidities who are ineligible for conventional surgery as well as demonstrating excellent outcomes.1,2 Catheter-based interventions include transcatheter aortic valve implantation (TAVI),3 percutaneous mitral valve … View more

Over the last three decades numerous transcatheter therapies for the treatment of congenital heart disease (CHD) have been developed. Interatrial Septal Defect Balloon atrial septostomy has been performed in patients with transposition physiology and in patients where egress of blood is needed from the left or the right atrium and in adults with pulmonary vascular disease where the creation of… View more

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,… View more

Among patients undergoing surgical valve replacement, 1–5 % of patients with an aortic valve replacement (AVR) and 2–12 % with a mitral valve replacement (MVR) may develop paravalvular regurgitation or ‘leak’ (PVL).1–3 In the era of transcatheter aortic valve replacement (TAVR) with first-generation balloon expandable valves, up to 17 % of patients may be left with moderate or severe PVL, also… View more

Paravalvular leak (PVL) occurs when there is backflow around a prosthetic valve. This can occur through a variety of causes. Paravalvular Leak is accompanied by regurgitation and is often a significant problem for patients with bioprosthetic or mechanical heart valves.1 Often manifesting as heart failure (85% of all presenting symptoms) and hemolysis (13–47% of all presenting symptoms and signs)… View more

The foramen ovale provides communication between both atria in utero, and although anatomical closure usually occurs in the first two years of life, it may remain patent (patent foramen ovale [PFO]) into adulthood. The autopsy prevalence of PFO was 27% among 965 otherwise normal hearts,1 and transoesophageal echocardiography detected PFO in 24.3% of 585 randomly sampled individuals.2 PFO is… View more

Imaging guidance is of major importance for successful outcomes in the interventional treatment of structural, congenital and valvular heart disease. Cardiac transcatheter treatment of these diseases is a rapidly growing field and, as a result, there has been substantial progress in image-guidance technology. During interventions, the major imaging focus is currently on echocardiography, which… View more

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… View more

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… View more
