Morristown Medical Center reaches significant milestone of performing over 4,000 TAVR

Morristown Medical Center's Gagnon Cardiovascular Institute's structural heart program reached a significant milestone of performing over 4,000 transcatheter aortic valve replacement (TAVR) procedures with well over 650 in 2022 alone.

Minimally invasive procedure enables patients to be out of the hospital within a few days

Minimally invasive, catheter-based transcatheter aortic valve replacement (TAVR) has revolutionized treatment of aortic stenosis (AS), and both American and European guidelines have approved its use. However, there is a perception that TAVR is more expensive than surgical aortic valve replacement (SAVR). A budget impact analysis comparing the two options now shows that TAVR is an affordable and effective strategy for the treatment of AS. The study appears in the Canadian Journal of Cardiology, published by Elsevier.

A simple and low-cost method to identify valve dysfunction

Aortic valve stenosis occurs when the aortic valve narrows, constricting blood flow from the heart through the artery and to the entire body.

New risk assessment tool predicts mortality for atrial fibrillation patients after completion of TAVR

A large-scale international study led by Mount Sinai has yielded the first risk score that can help predict mortality for patients with atrial fibrillation (AFib) who have undergone a successful transcatheter aortic valve replacement (TAVR) and discharged home.

Less invasive procedure for common heart condition just as effective as conventional open-heart surgery

A study led by researchers at the National Institute for Health and Care Research Leicester Biomedical Research Centre has shown that a less invasive heart procedure for a common condition is just as effective as conventional open-heart surgery.

Calcium supplements may increase risk of death in older people with aortic valve stenosis

Calcium supplements, frequently given to older people to lessen the risk of brittle bones (osteoporosis) and fractures, are linked to a heightened risk of death among those with aortic valve stenosis, a progressive and potentially fatal condition, finds research published online in the journal Heart.

Experimental siRNA therapeutic shows promise to reduce an important driver of heart disease risk

While there are effective therapies to reduce the risk of heart disease by lowering low-density lipoprotein (LDL), or "bad" cholesterol, and other lipids, to date there are no approved treatments to lower lipoprotein(a), a lesser-known driver of heart disease risk.

Experimental siRNA therapy reduces a key driver of heart disease risk by up to 98%

Findings from a new Cleveland Clinic-led phase 1 trial show that an experimental "gene silencing" therapy reduced blood levels of lipoprotein(a), a key driver of heart disease risk, by up to 98%.

Research reveals the burden of aortic valve stenosis in the UK

An estimated 300,000 people in the UK have aortic valve stenosis, a progressive and potentially fatal condition, suggests research published in the open access journal Open Heart.

Oral penicillin may be a safer option for people with high-risk rheumatic heart disease

A growing body of evidence indicates that some people thought to have an allergic response to injectable penicillin, the standard treatment for rheumatic heart disease, may instead be experiencing a cardiac reaction to the medicine, according to a new American Heart Association presidential advisory published today in Journal of the American Heart Association.

Valve replacement surgery may be beneficial for patients with asymptomatic severe aortic stenosis

For people experiencing severe aortic stenosis who do not have symptoms or need symptom relief, early aortic valve replacement surgery may be beneficial because it reduces the risk of death, heart attack, stroke and heart failure, according to late-breaking research presented today at the American Heart Association's Scientific Sessions 2021.

Trial finds similar five-year outcomes with transcatheter or surgical aortic valve replacement

New five-year data from the SURTAVI trial found that there was no difference in all-cause mortality or stroke between patients at intermediate surgical risk who had transcatheter aortic valve replacement (TAVR) or surgery.

Cardiac CTA parameters predict mortality after transcatheter aortic valve replacement

According to ARRS' American Journal of Roentgenology (AJR), cardiac CTA-derived left atrium emptying fraction (LAEF) improves predictive performance of established clinical risk scores and may be used to assess patients' risk during pre-transcatheter aortic valve replacement (TAVR) workup and postprocedural surveillance.
