Novel biodegradable magnesium-alloy tracheal stents for children with airway obstruction

Pediatric laryngotracheal stenosis (LTS), a narrowing of the airway in children, is a complex medical condition. While it can be something a child is born with or caused by injury, the condition can result in a life-threatening emergency if untreated.

Henry Ford Health System is first in the U.S. to perform a procedure using CG-100 intraluminal device

Henry Ford Health System is the first in the country to perform a procedure using the CG-100™ intraluminal device, which is temporarily inserted into the gastrointestinal tract and designed to reduce diverting stoma rates, and the need for an ostomy bag, in patients undergoing gastrointestinal resection procedures due to colorectal cancer 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.

Small molecule restores normal heart development in animal model with rare genetic disorder

A research team at the Greenwood Genetic Center has successfully used small molecules to restore normal heart and valve development in an animal model for Mucolipidosis II (ML II), a rare genetic disorder. Progressive heart disease is commonly associated with ML II.

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 provides evidence on non-invasive diagnostic procedures for people with suspected CHD

The German Institute for Quality and Efficiency in Health Care (IQWiG) used an evidence map to investigate to what extent informative evidence exists on the benefit and harm of the diagnostic procedures "non-invasive computed tomography angiography" (CTA) and "stress MRI" in people with suspected coronary heart disease (CHD).

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).
