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.

Globaldata: Cardiovascular procedures not impacted by COVID-19 as heavily as other therapy areas

The COVID-19 crisis is not impacting cardiovascular procedures as heavily as it is other therapy areas, since the majority of these procedures are essential, according to GlobalData, a leading data and analytics company. GlobalData estimates that 96.7% of cardiovascular procedures performed in the US are essential procedures.

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.

Heart valve that grows with the child lowers the need for risky multiple heart surgeries

A breakthrough medical technology can save the lives of children with heart defects. Scientists have developed the first-ever heart valve that grows with the child, reducing the need for risky heart surgeries 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.

MCG scan shows promise in evaluating chest pain for acute coronary artery syndrome

Undiagnosed chest pain sends 8-10 million Americans to Emergency Departments annually, making it the second most common complaint. Emergency physicians must rapidly identify patients whose chest pain is cardiac-related.

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.
