Nearly one in 10 develop AF after aortic valve surgery

More research is needed to identify optimal management strategies, researchers say

Patients who develop atrial fibrillation after transcatheter aortic valve replacement (TAVR) are more likely to die within one year of surgery than those who don't develop AF, shows US research.

The observational study of more than 13,000 patients shows that nearly 10% (1100) of patients undergoing TAVR develop new-onset AF after surgery.

These patients were more likely to have had non-transfemoral access, as well as be older, female, have lower left ventricular function and severe COPD. 

Meanwhile, patients with a pacemaker had a lower risk of AF.

One year after surgery, mortality, stroke and bleeding rates were higher for patients with new AF than for patients without AF. 

They were 37% more likely to die one year post-op and nearly 32% were rehospitalised for bleeding compared with 23% of patients without AF.
