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.

Patients treated with edoxaban after TAVR do not find reduction in mini strokes, blood clots in the brain

Patients treated with the blood thinner edoxaban for six months after a heart valve replacement procedure experienced fewer symptomless blood clots inside the heart valve replacement than patients who were treated with two antiplatelet drugs, according to data presented at the American College of Cardiology's 71st Annual Scientific Session.

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.

Study finds no difference in physician-patient gender concordance

While some studies suggest female patients treated by female physicians have better outcomes, there does not appear to be a relationship between operator and patient gender and outcome in patients undergoing coronary angioplasty or stenting. T

REFLECT II clinical trial evaluates safety and efficacy of cerebral embolic deflection filter

The REFLECT II randomized clinical trial evaluating the safety and efficacy of a device designed to reduce cerebral embolization and ischemic stroke, complications of transcatheter aortic valve replacement (TAVR), found that the device met the primary safety endpoint compared to historical controls but did not demonstrate superiority of the device for the primary hierarchical efficacy endpoint.

New self-expanding bioprosthetic valve used in TAVR fails to demonstrate non-inferiority

In a randomized clinical trial, SCOPE II, a new self-expanding bioprosthetic valve used in transcatheter aortic valve replacement (TAVR) failed to demonstrate non-inferiority compared to an existing self-expanding valve.

3D-printed organ model can improve surgical outcomes for heart patients

Researchers from the University of Minnesota, with support from Medtronic, have developed a groundbreaking process for multi-material 3D printing of lifelike models of the heart's aortic valve and the surrounding structures that mimic the exact look and feel of a real patient.

TAVR market shows hopeful signs of resiliency, says GlobalData

“Following Edwards Lifesciences’ announcement of an expected 5% growth for its transcatheter aortic valve replacement (TAVR) business, GlobalData observes hopeful signs of resiliency in the TAVR market.

Thinner tissues induce problematic flutter in aortic heart valve replacements

You're in the middle of the aorta, the body's pipeline for oxygen-rich blood, looking back toward the heart's primary pump, the left ventricle.

COVID-19 and blood group in aortic valve replacement

The COVID-19 pandemic has been found to cause disproportionate harm in patients with cardiovascular disease, especially among the elderly population, among other risk factors. However, a new study published on the preprint server medRxiv* in June 2020 is the first to report its clinical features in patients with aortic stenosis who have had a transcatheter aortic valve replacement (TAVR).

UC physician-researcher explores why TAVR doesn't work well for some patients

A University of Cincinnati physician-researcher says unlocking the key to how platelets function before, after and during transcatheter aortic valve replacement (TAVR) may provide insight as to why some patients undergoing the heart procedure have better outcomes than others.

Trial confirms the effectiveness of TAVR strategy in a real-world setting

Patients who underwent transcatheter aortic valve replacement (TAVR) did not have a higher rate of death at one year compared with those who had their heart valve replaced via open-heart surgery, according to research presented at the American College of Cardiology's Annual Scientific Session Together with World Congress of Cardiology.

TAVR shows high rate of success and low risk of death in patients with bicuspid valve

Transcatheter aortic valve replacement procedures had a high rate of success and low risk of death or disabling stroke at 30 days in patients with a bicuspid, or two-leaflet, aortic valve, according to research presented at the American College of Cardiology's Annual Scientific Session Together with World Congress of Cardiology.

Adding antiplatelet therapy to oral anticoagulants raises risk for TAVR patients with atrial fibrillation

Patients with atrial fibrillation who took oral anticoagulants alone after undergoing transcatheter aortic valve replacement had a lower rate of bleeding complications without an increased risk of clotting-related complications compared to patients who took antiplatelet medication in addition to oral anticoagulants, in a trial presented at the American College of Cardiology's Annual Scientific Session Together with World Congress of Cardiology.

Research favors the use of surgical aortic valve replacement in young and middle-aged adults

While transcatheter aortic valve replacement (TAVR) continues to expand its pool of eligible patients, open heart surgery- resulting in excellent patient survival and fewer strokes when compared to TAVR- is the best option for young and middle-aged adults with aortic valve disease- at least for now, according to a scientific presentation at the 56th Annual Meeting of The Society of Thoracic Surgeons.

More patients may opt for minimally invasive heart valve procedure

Since August, when the Food and Drug Administration approved a minimally invasive heart valve procedure for an expanded group of patients with aortic stenosis, Raj Makkar, MD, vice president of Cardiovascular Innovation and Intervention at Cedars-Sinai, says many more patients are opting for the procedure known as transcatheter aortic valve replacement.
