Molecular signature could be mechanistically related to bleeding risk after heart surgery

Postoperative bleeding is one of the most common complications after cardiac surgeries, especially in open heart ones. In this kind of surgery, surgeons need to resort to cardiopulmonary bypass, an extracorporeal circuit composed of tubes and machines that replicate the function of the heart and lungs.

Minimally invasive procedure enables patients to be out of the hospital within a few days

Minimally invasive, catheter-based transcatheter aortic valve replacement (TAVR) has revolutionized treatment of aortic stenosis (AS), and both American and European guidelines have approved its use. However, there is a perception that TAVR is more expensive than surgical aortic valve replacement (SAVR). A budget impact analysis comparing the two options now shows that TAVR is an affordable and effective strategy for the treatment of AS. The study appears in the Canadian Journal of Cardiology, published by Elsevier.
