Anti-coagulant medications quickly resolve blood clots that could impair valve motion

Heart valve replacements made from tissue (bioprosthetic valves) have long been thought to be spared the complication of blood clot formation. Researchers have now found that about 15 percent of all bioprosthetic aortic heart valve patients develop blood clots on the leaflets affecting valve opening, regardless of whether the patient received the new valve via open-heart surgery or a minimally-invasive catheter procedure, a new study from the Cedars-Sinai Heart Institute shows.

Non-invasive FFRCT test can reduce need for invasive tests in patients having chest pain

According to results of the PLATFORM (Prospective LongitudinAl Trial of FFRCT: Outcome and Resource Impacts) trial, a test known as FFRCT can obviate the need for invasive tests in up to 61% of patients who have chest pain and suspected coronary artery disease.

Arterial shunt in hybrid palliation better for hypoplastic left heart syndrome treatment

Children born with the major congenital heart defect hypoplastic left heart syndrome (HLHS) often must undergo a series of corrective surgeries beginning at birth. While most have the standard three-stage Norwood procedure, a hybrid strategy has been introduced to offset some disadvantages associated with the Norwood surgeries. In a report in The Journal of Thoracic and Cardiovascular Surgery, investigators compare whether outcomes can be improved if an arterial shunt is used as a source of pulmonary blood flow rather than the more conventional venous shunt as part of the hybrid strategy of HLHS surgical reconstruction.

Orlando Health Heart Institute first in Central Florida to use CoreValve Evolut R System to replace heart valves

Leading edge heart valve technology is helping improve patient outcomes and giving doctors greater accuracy when implanting replacement valves. Interventional cardiologists and cardiovascular surgeons at the Orlando Health Heart Institute are the first in Central Florida to use the newly approved recapturable, self-expanding CoreValve Evolut R System.

Stopping cocaine use may lower levels of ET-1 protein that plays key role in coronary artery disease

For people who use cocaine, stopping or reducing cocaine use is associated with decreased levels of endothelin-1 (ET-1)--a protein that plays a key role in the development of coronary artery disease, reports a study in the Journal of Addiction Medicine, the official journal of the American Society of Addiction Medicine.

Patients who receive intracranial stents at increased risk of experiencing another stroke

The risk of experiencing another stroke is higher if patients, after dilation of their blood vessels in the brain, receive not only clot-inhibiting drugs, but also have stents inserted. The recently published results of the VISSIT study confirm this conclusion of a rapid report by the German Institute for Quality and Efficiency in Health Care (IQWiG) of October 2014.

Re-Inflating balloon after carotid stenting appears to double risk of stroke and death

Patients with severe blockages typically undergo surgery to scrape off the fatty deposits from the walls of the vessel, the preferred approach that carries notably lower stroke risk but is not recommended for people too sick to withstand traditional surgery...

New Johns Hopkins study shows re-inflating balloon after carotid stenting fuels stroke risk

After reviewing outcomes from thousands of cases, researchers at Johns Hopkins report that patients with blocked neck arteries who undergo carotid stenting to prop open the narrowed blood vessels fare decidedly worse if their surgeons re-inflate a tiny balloon in the vessel after the mesh stent is in place.

National study comparing minimally invasive lumbar decompression (mild) with epidural steroid injections (ESIs) reaches full enrollment

Lumbar spinal stenosis is primarily a degenerative, age-related narrowing of the lower spinal canal resulting in compression of the nerve roots. MILD treats this compression by removing small portions of lamina and hypertrophic ligamentum flavum in a minimally invasive, outpatient procedure through an opening about the size of a baby aspirin...
