Study links atrial fibrillation to poorer brain clearance and cognitive decline

Researchers found that people with atrial fibrillation had lower MRI-based glymphatic activity and poorer cognitive performance than healthy controls, with the greatest impairment seen in non-paroxysmal AF. In patients who underwent catheter ablation, glymphatic activity improved after sinus rhythm was restored, suggesting a possible link between heart rhythm, brain waste clearance, and cognition.

Transcatheter valve-in-valve procedure improves short-term outcomes in high-risk patients

In patients with a poorly functioning bioprosthetic mitral valve in the heart, a minimally invasive procedure to insert a new valve was associated with a lower rate of death or disabling stroke within one year, compared with patients who underwent standard repeat mitral valve replacement surgery, according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Novel vFFR method performs similar to invasive coronary assessment

A novel, minimally invasive method of determining whether fatty deposits in a coronary artery are restricting blood flow to a patient's heart performed similarly to the standard, more-invasive procedure in a large multi-country European randomized trial presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

AI-based tool matches standard method for coronary blood flow assessment

A novel, minimally invasive computer software-based method that uses artificial intelligence to determine whether plaques in a coronary artery are restricting blood flow to the patient's heart performed similarly to the standard, more invasive wire-based procedure, according to a large international randomized trial presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Angioplasty improves symptoms in chronic total coronary occlusion patients

In what is believed to be the first randomized placebo-controlled trial of its kind, patients with a chronic total blockage of a coronary artery who received a nonsurgical procedure to reopen the artery showed statistically significant reductions in chest pain and improvements in quality of life compared with patients who received a placebo procedure.
