A stenosis is an abnormal narrowing in a blood vessel or other tubular organ or structure.

Unidentified valvular heart disease very common in elderly

Over half of community-living elderly people are likely to have valvular heart disease, show findings of OxVALVE-PCS.

Everolimus-eluting bioresorbable vascular scaffold shows promise in PAD

A first-in-human trial of an everolimus-eluting bioresorbable vascular scaffold has shown that the device can achieve a high 2-year patency rate and low 2-year target lesion revascularisation rate in patients with peripheral artery disease involving the external iliac artery and superficial femoral artery.

Unseen health risks of aortic stenosis: an interview with Dr Shelley Rahman Haley

Aortic stenosis means narrowing of the aortic valve, which is the out flow valve from the left ventricle, the pumping chamber of the heart. This is the valve which opens to allow blood to flood out of the heart and all-round the body.

Persistent low flow warns of mortality risk after TAVR

Patients with persistent low flow at discharge after transcatheter aortic valve replacement have an increased risk of dying during the subsequent year, report researchers.

Penn researchers explore possibilities to improve outcomes in low flow AS patients treated with TAVR

Aortic stenosis (AS), the narrowing of the aortic valve in the heart which causes restricted blood flow, is one of the most common and serious valve disease problems. For patients with one type of AS - low flow - transcatheter aortic valve replacement (TAVR), a minimally invasive procedure which corrects the damaged aortic valve, is often the best option for restoring the heart's normal pumping function.

Mayo researchers develop extremely precise assay to measure age-associated changes in GDF11

Researchers at Mayo Clinic have developed an accurate way to measure a circulating factor, called GDF11, to better understand its potential impact on the aging process.

Post PCI symmetry important for good clinical outcome

Postprocedural asymmetry following percutaneous coronary intervention is associated with an increased risk of adverse clinical outcome, particularly in patients with suboptimal expansion, researchers report.

TAVI matches SAVR for early and midterm mortality

Transcatheter aortic valve implantation has similar early and midterm mortality to surgical aortic valve replacement in patients with aortic stenosis, including those at low to intermediate risk, show results of a systematic review and meta-analysis.

Artificial intelligence could refine CAD prognosis

A study shows that machine learning can predict mortality in patients with coronary artery disease with greater accuracy than models based on coronary computed tomographic angiography or clinical variables.

Experts discuss new therapy options for stroke treatment at EAN Congress

There are more well-founded therapy options for the treatment of strokes than ever before. Care has to be reorganised before these innovations are actually used on patients. At the Congress of the European Academy of Neurology in Copenhagen, experts are discussing just how to do that successfully - from guidelines for the use of thrombectomy procedures all the way to the structure and expansion of stroke care units.

Health of 1 million over 65s at risk from low awareness of heart valve disease

New research has revealed that the UK’s over 60s could seriously be jeopardising their health due to a lack of awareness of heart valve disease.

Strategy choice impacts long-term mortality in bifurcation stenting

Using a provisional rather than a planned two-stent strategy for coronary bifurcation stenting may halve long-term mortality, pooled study data show.

Japanese surgeons develop new technique to relieve airway obstruction in children

Several pediatric medical conditions, such as congenital heart disease, vascular compression, and congenital softening of the cartilage lining the trachea or bronchi, can compromise the airway and cause breathing difficulty.

Study estimates half of transcatheter heart valves undergo degeneration within 10 years

Half of transcatheter heart valves may undergo degeneration within 10 years, according to estimates from the first study investigating the long-term durability of these valves in patients undergoing transcatheter aortic valve implantation (TAVI) reported at EuroPCR 2016.

RDAVR system improves survival of patients with severe aortic stenosis

When replacing a defective aortic valve with a new one, restoring function is the first priority. However, variables such as durability, length of surgery, duration of heart stoppage, size of the surgical incision, postoperative pain, and complications are other important considerations.

Arterial switch to 12 o'clock position linked to myocardial ischaemia risk in adolescence

Arterial switch to the 12 o'clock position is associated with abnormal coronary perfusion in adolescence, reveals research presented today at EuroCMR 2016.1 Babies born with transposition of the great arteries (TGA) undergo the arterial switch operation in the first days of life.
