BACKGROUND: Aortic stenosis (AS) is a common valvular abnormality and transcatheter aortic valve implantation (TAVI) is being increasingly used to treat patients considered too high risk for conventional surgery. We aimed to assess the prevalence of...

Transradial access (TRA) is increasingly used worldwide for percutaneous interventional procedures and associated with lower bleeding and vascular complications than transfemoral artery access. Radial artery occlusion (RAO) is the most frequent post-...

Characteristics and outcome of acute heart failure patients according to the severity of peripheral oedema (2019)
Journal Article
Mamas, M., Rashid, M., & Nolan, J. (2019). Characteristics and outcome of acute heart failure patients according to the severity of peripheral oedema. International Journal of Cardiology, 40 -46. https://doi.org/10.1016/j.ijcard.2019.03.020

BACKGROUND: Most trials of patients hospitalized for heart failure focus on breathlessness (alveolar pulmonary oedema) but worsening peripheral oedema is also an important presentation. We investigated the relationship between the severity of periphe... Read More about Characteristics and outcome of acute heart failure patients according to the severity of peripheral oedema.

Mode of presentation and mortality amongst patients hospitalized with heart failure?: a report from The First Euro Heart Failure Survey (2019)
Journal Article
