When do you replace mitral valve guidelines?

The most common indication for mitral valve surgery is symptomatic chronic severe primary mitral regurgitation, usually owing to degenerative valve disease, with a left ventricular ejection fraction (LVEF) of >30% (Class I recommendation); mitral valve surgery is indicated in symptomatic patients with severe LV …

What is the criteria for heart valve replacement?

Indications for aortic valve replacement (surgical or transcatheter) are as follows: Severe high-gradient AS with symptoms (class I recommendation, level B evidence) Asymptomatic patients with severe AS and LVEF < 50 (class I recommendation, level B evidence)

Who is not a candidate for heart valve replacement?

For TAVR to be recommended, the evaluation must confirm the following: You have aortic stenosis that is severe in nature and is causing symptoms. You are not a candidate for surgical aortic valve replacement or you’re at high risk for surgery and likely would benefit from TAVR therapy.

What is pressure half time for aortic insufficiency?

A pressure half-time of greater than 500 milliseconds (ms) is consistent with mild aortic regurgitation, from 500 to 200 ms with moderate, and of less than 200 ms with severe AR.

How long do you live after aortic valve replacement?

Pooled data from 85 studies estimated that 89.7% of people survived for two years after surgery, 78.4% at five years, 57.0% at 10 years, 39.7% at 15 years, and 24.7% at 20 years.

Which valve is most commonly repaired?

The mitral valve is the most common valve to be repaired. Only rarely is the tricuspid valve or the pulmonic valve repaired or replaced.

Do all heart valves require anticoagulation?

DOACs are not used — DOACs should not be used in patients with mechanical prosthetic heart valves. All patients with mechanical prosthetic valves require lifelong anticoagulation with a VKA (eg, warfarin).

Why can’t you take eliquis If you have a heart valve?

Blood Thinner Dangerous for Patients With Artificial Heart Valves, Study Finds. THURSDAY, Sept. 26 (HealthDay News) — When used by patients with mechanical heart valves, the blood thinner Pradaxa raises the risk of both dangerous clots and bleeding around the heart, a new study says.

What is a normal pressure half-time?

Pressure half-time is 60 msec. Flow in systole is mitral regurgitation. in 20 adults ages 21-72 years was 25-55 msec (mean 43 msec). In 20 children ages 1-16 years, pressure half-time was 20-60 msec (mean 49 msec).

Is a transcatheter valve-in-valve procedure reasonable at a comprehensive valve center?

For high surgical risk patients with prosthetic valve dysfunction (stenosis or valve regurgitation), a transcatheter valve-in-valve procedure is reasonable at a Comprehensive Valve Center (Class 2a).

What are the treatment options for asymptomatic heart valve disease?

Consultation with or referral to a Primary Valve Center or a Comprehensive Valve Center is reasonable for the discussion of treatment options in the setting of asymptomatic patients with severe valve disease, patients who might benefit from valve repair rather than valve replacement, and among patients with multiple comorbidities.

What’s new in the 2020 guidelines for valvular heart disease?

The 2020 guideline for the management of patients with valvular heart disease replaces the American Heart Association/American College of Cardiology (AHA/ACC) 2014 guideline and the 2017 focused update.

What are the contraindications for anticoagulation after mitral valve replacement?

Bioprosthetic SAVR or mitral valve replacement: Anticoagulation with VKA to an INR of 2.5 is reasonable for 3-6 months postoperatively (Class 2b). Mechanical valve prosthesis: The use of direct thrombin inhibitors (dabigatran) or anti-Xa direct oral anticoagulants remains a Class 3 contraindication.
