An artificial heart valve
is a device implanted into the heart of a patient to replace a dysfunctional native heart valve
(valvular heart disease).
In a clinical study to evaluate safety and effectiveness, 503 patients with severe aortic stenosis at low risk for surgical complications were randomly selected to have aortic valve replacement with the Sapien 3 transcatheter heart valve
, and 497 were randomly selected to have aortic valve replacement with traditional open-heart surgery using an approved surgical tissue valve.
At an average 15- to 17-month follow-up, the results of the transcatheter heart valves
were comparable to those of traditional open-heart surgery.
The latest American College of Chest Physicians guideline for antithrombotic and thrombolytic therapy recommends the addition of low-dose aspirin (50-100 mg/day) to warfarin therapy in patients with mechanical heart valves

Nakano said he hopes that the discovery will pave the way to more permanently solve heart valve
conditions, perhaps by boosting or inhibiting heart-derived macrophages' activity in order to regulate heart valve
HVD occurs when the heart valves

Though rare, valve infections can be caused by something as simple as getting the teeth cleaned in patients who have a predisposition for valve disease, or a family history of heart valve

Healthcare company Abbott disclosed on Tuesday the receipt of approval from the US Food and Drug Administration (FDA) for the world's smallest Masters HP 15mm rotatable mechanical heart valve
that will allow doctors to treat babies and toddlers in need of a mitral or aortic valve replacement.
