Study reveals risk factors and outcomes of infective endocarditis after TAVR

Study reveals risk factors and outcomes of infective endocarditis after TAVR

Among patients undergoing transcatheter aortic valve replacement, younger age, male sex, history of diabetes mellitus, and moderate to severe residual aortic regurgitation were significantly associated with an increased risk of infective endocarditis, and patients who developed endocarditis had high rates of in-hospital mortality and 2-year mortality, according to a study appearing in the September 13 issue of JAMA.

New study suggests major change in treatment of significant number of ACS patients

New study suggests major change in treatment of significant number of ACS patients

More than one quarter of heart attack patients who are normally treated with stents to re-open their blocked arteries might be able to forgo this procedure and receive anti-thrombotic medications only, according to results of a pilot study. [More]
BBK II trial compares two commonly used stenting techniques for coronary bifurcation

BBK II trial compares two commonly used stenting techniques for coronary bifurcation

Coronary bifurcations - a type of coronary artery narrowing - are best treated with a technique known as culotte stenting, as opposed to T-and-protrusion (TAP) stenting, when there is need for a side-branch stent according to results of the BBK II (Bifurcations Bad Krozingen) trial. [More]
CE-MARC 2 trial finds way to reduce rates of unnecessary invasive angiography

CE-MARC 2 trial finds way to reduce rates of unnecessary invasive angiography

Initial investigation of patients with suspected coronary heart disease (CHD) using functional imaging - rather than guideline-directed care - resulted in significantly less unnecessary angiography, according to results of the CE-MARC 2 trial. [More]

Lipoprotein apheresis may have new role in patients with refractory angina

Initial investigation of patients with suspected coronary heart disease (CHD) using functional imaging - rather than guideline-directed care - resulted in significantly less unnecessary angiography, according to results of the CE-MARC 2 trial. [More]
PACIFIC study may offer guidance to choose from number of non-invasive coronary artery imaging

PACIFIC study may offer guidance to choose from number of non-invasive coronary artery imaging

For patients presenting for the first time with suspected coronary artery disease (CAD) clinicians have had a number of non-invasive diagnostic tests to choose from, but little evidence for which is best. [More]
Invasive imaging technique can help achieve better outcomes in patients undergoing PCI

Invasive imaging technique can help achieve better outcomes in patients undergoing PCI

An invasive imaging technique called optical coherence tomography (OCT) can visualize the coronary arteries in patients undergoing percutaneous coronary intervention (PCI) and lead to better outcomes compared to standard angiography-guided PCI, according to new findings reported here. [More]
Alcohol-related hospitalisation linked to increased risk of ischaemic stroke in atrial fibrillation patients

Alcohol-related hospitalisation linked to increased risk of ischaemic stroke in atrial fibrillation patients

Alcohol related hospitalisation is associated with a doubled risk of ischaemic stroke risk in patients with non-valvular atrial fibrillation, according to a study presented at ESC Congress 2016 today by Dr Faris Al-Khalili, cardiologist, Karolinska Institutet, Danderyd Hospital, Stockholm, Sweden.

PinnacleHealth replaces aortic valve in two patients using minimally invasive surgery

PinnacleHealth replaces aortic valve in two patients using minimally invasive surgery

This week, PinnacleHealth became the first hospital in the country to implant the EDWARDS INTUITY Elite valve, a rapid deployment device for surgical aortic valve replacement, after U.S. Food and Drug Administration approval. [More]
Cerebral protection device reduces brain lesions after TAVI in patients with severe aortic stenosis

Cerebral protection device reduces brain lesions after TAVI in patients with severe aortic stenosis

Among patients with severe aortic stenosis (narrowing of the aortic valve) undergoing transcatheter aortic valve implantation, the use of a cerebral protection device (a filter that captures debris [tissue and plaque] dislodged during the procedure) reduced the number and volume of brain lesions, according to a study appearing in the August 9 issue of JAMA.

SAPIEN 3 trans-catheter aortic valve replacement system improves survival in patients with aortic stenosis

SAPIEN 3 trans-catheter aortic valve replacement system improves survival in patients with aortic stenosis

Overall one-year survival was over 85 percent for high-risk or inoperable patients who underwent aortic valve replacement with the SAPIEN 3 trans-catheter aortic valve replacement system, according to a study published in the July 12 issue of the American Heart Association journal Circulation.

Clinical study examines new treatment option for aortic stenosis patients with larger valve structure

Clinical study examines new treatment option for aortic stenosis patients with larger valve structure

A clinical trial exploring a new minimally invasive treatment option for some patients with severe aortic stenosis recently launched at Baylor Jack and Jane Hamilton Heart and Vascular Hospital. [More]
UTHealth researchers examine effectiveness of Sapien 3 TAVR in low-risk patients with aortic stenosis

UTHealth researchers examine effectiveness of Sapien 3 TAVR in low-risk patients with aortic stenosis

The Structural Heart Program team at McGovern Medical School at The University of Texas Health Science Center at Houston is among the first in the country to investigate the safety and effectiveness of Edwards Lifesciences Sapien 3 transcatheter aortic heart valve in low surgical risk patients who suffer from severe aortic valve disease.

Unidentified valvular heart disease very common in elderly

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. [More]
Everolimus-eluting bioresorbable vascular scaffold shows promise in PAD

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

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. [More]
Persistent low flow warns of mortality risk after TAVR

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. [More]
Penn researchers explore possibilities to improve outcomes in low flow AS patients treated with TAVR

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. [More]

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. [More]
