Current surgical risk scores overestimate risk in mini-AVR procedures

Minimally invasive aortic valve replacement surgery is a safer procedure than indicated by current surgical risk scores, according to Joseph Lamelas, M.D., chief and program director of cardiothoracic surgery at the University of Miami Health System.

Scoring system can help improve the diagnosis of concomitant heart diseases

Aortic stenosis is one of the most common heart valve defects. Its prevalence increases with age and it often requires treatment.

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.

Study shows best antiplatelet treatment after transcatheter aortic valve implantation

The POPular TAVI trial has challenged current guideline recommendations on antiplatelet treatment after transcatheter aortic valve implantation (TAVI) in patients not taking oral anticoagulation. The findings are presented in a Hot Line session today at ESC Congress 2020.

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.

Study reveals how overactive immune cells aggravate heart valve disease

A new study using organ-on-a-chip technology reveals how overactive immune cells aggravate heart valve disease and how this damaging hyperactivity could potentially be controlled.

Less invasive heart treatment now available to all Australians living with aortic stenosis

All Australians living with symptoms of severe aortic stenosis no longer face open heart surgery as the only treatment option, with public access to a less invasive therapy – previously reserved for only the sickest patients – now available to all Australians requiring treatment.

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.

How comorbidities affect SARS-CoV-2 viral entry

Almost from the start of the current COVID-19 pandemic, it has become clear that individuals suffering from other medical conditions like diabetes, cardiovascular disease, and lung disease are far more likely to contract the infection and to have a poorer outcome.

New study highlights inequity in access to TAVR procedure across Canada

Transcatheter aortic valve replacement is a revolutionary technology for the treatment of patients with severe calcific aortic stenosis.

Study adds a new dimension to heart disease

Using the Canadian Light Source (CLS) at the University of Saskatchewan, Marta Cerruti, an Associate Professor in McGill's Department of Materials Engineering, and her team analyzed damaged heart valves from patients who had undergone transplants.

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.

AI-based approach may allow EKGs to be used for detecting hypertrophic cardiomyopathy

An approach based on artificial intelligence may allow EKGs to be used to screen for hypertrophic cardiomyopathy in the future.

Study clarifies pros and cons of open-heart surgery versus TAVR for treating aortic stenosis

A new study from the Smidt Heart Institute at Cedars-Sinai and other centers nationwide shows that patients who underwent a minimally invasive transcatheter aortic-valve replacement, had similar key 5-year clinical outcomes of death and stroke as patients who had traditional open-heart surgery to replace the valve.

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.

Women with gestational hypertension have elevated cardiovascular risk later in life

Research published online today in Journal of the American College of Cardiology, confirms that women who have gestational hypertension or preeclampsia in at least one pregnancy will have higher cardiovascular risk than women without such a history, and that this elevated risk persists at least into their 60s.

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.
