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

Over the past 30 years, several percutaneous transcatheter technologies and devices for interventions in structural heart diseases (SHDs) have been introduced (see Table 1). There are numerous technologies that are in development or are currently being used to treat patients with SHD that use transcatheter techniques. The variety of percutaneous treatment approaches has led to a revolution and… View more

Coronary CTA has rapidly gone from a test with potential to be considered a first-line test for patients with stable chest pain.1 It provides robust ability to exclude atherosclerosis and coronary artery stenosis and more recently has been shown to inform and guide clinical treatment making in a fashion that enables a reduction in myocardial infarction when compared to traditional stress testing… View more

Annular Rupture During TAVI
Author(s): JJ Coughlan , Thomas J Kiernan , Darren Mylotte , et al Added: 3 years ago
Transcatheter aortic valve implantation (TAVI) has emerged as an alternative treatment for symptomatic severe aortic stenosis in patients deemed to be at high operative risk for conventional surgical aortic valve replacement (SAVR). In these patients, TAVI has lower all-cause mortality than SAVR1 and recent data also suggest equipoise between these therapies in intermediate-risk patients.2–5… 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

Bicuspid aortic valve is the most common congenital cardiac malformation, affecting 1.3% of the population, and responsible for a significant proportion of aortic valve replacement in adults.1-3 Clinical presentation varies from severe valve disease in infancy to asymptomatic valve in old age, but symptoms typically develop in adulthood. Surgical aortic valve replacement is generally required at… View more
