Rethinking mechanical heart valves in the aortic position: new paradigms in design and testing

Frontiers in Cardiovascular Medicine

Bileaflet mechanical heart valves (MHV) remain a viable option for aortic valve replacement, particularly for younger patients and patients from low- and middle-income countries and underserved communities. Despite their exceptional durability, MHV recipients are at increased risk of thromboembolic complications.

Heart-Valve-Surgery.Com and Medtronic Launch Novel "Aortic Stenosis Patient Activation Platform" to Empower Patients

DAIC

Aortic stenosis is a narrowing of the aortic valve which prevents the aortic leaflets from opening and closing properly. As a result, the heart must work "over time" to pump blood throughout the body. Without treatment, up to 50% of patients will die 24 months after the onset of symptoms1.

The importance of tissue science and valve design in relation to durability and hemodynamics of the DurAVR aortic heart valve

Frontiers in Cardiovascular Medicine

IntroductionClinical evidence highlighting the efficacy and safety of transcatheter aortic valve replacement (TAVR) and the 2019 Food and Drug Administration (FDA) approval for TAVR in low-risk (younger) patients has created a demand for durable and long-lasting bioprosthetic heart valve (BHV) leaflet materials.

World's most common heart valve disease linked to insulin resistance in large national study

Science Daily - Heart Disease

A large new population study of men over 45 indicates insulin resistance may be an important risk factor for the development of the world's most common heart valve disease -- aortic stenosis (AS).

Can this device prevent a stroke during a heart valve operation? New research shows potential benefit

Science Daily - Heart Disease

Recently published research shows a medical device may be beneficial for patients who have previously had a stroke and are planning to undergo a transcatheter aortic valve replacement, a type of heart valve operation.

Predictors of permanent pacemaker requirement in aortic stenosis patients undergoing self-expanding valve transcatheter aortic valve replacement using the cusp overlap technique

Frontiers in Cardiovascular Medicine

IntroductionSince TAVR was approved for lower-risk aortic stenosis (AS) patients, managing post-implantation conduction disturbances has become crucial, especially with self-expanding heart valves (SEV).
