What is mitral valve dehiscence?

What is mitral valve dehiscence?

Perivalvular leak due to valve dehiscence is a serious, yet uncommon complication of mitral valve replacement surgery. It is estimated to occur in 7-17% of patients, with 1-3% of patients requiring reoperation due to symptoms of heart failure [1,2].

What happens if mitral valve ruptures?

Rupture leads to acute mitral valve regurgitation, pulmonary edema, and cardiogenic shock. Survival is dependent on prompt recognition and surgical intervention.

What is valvular dehiscence?

Prosthetic cardiac valve dehiscence refers to breakdown of sutures leading to partial or complete detachment of the prosthesis from annulus; it is an uncommon complication which is reported in 0.1–1.3% of patients who undergo aortic valve replacement. 1.

What is mitral valve ring?

The ring around a valve in the heart (annulus) can widen and change from its usual shape. This may occur when the heart is enlarged or if you have a leaky valve (valve regurgitation). When the ring is widened, the valve flaps attached to the ring may not open and close correctly.

What is infective endocarditis?

Infective endocarditis, also called bacterial endocarditis, is an infection caused by bacteria that enter the bloodstream and settle in the heart lining, a heart valve or a blood vessel. IE is uncommon, but people with some heart conditions have a greater risk of developing it.

What is Paravalvular leak?

Paravalvular leak, also called paravalvular regurgitation, refers to a leak caused by a space left between natural heart tissue and the valve replacement from a previous transcatheter aortic or mitral valve replacement. This condition most often affects the mitral valve, rather than the aortic valve.

Is a slightly leaking heart valve serious?

With a leaky valve, sometimes not enough blood gets pumped to the rest of the body. Heart valve leakage/regurgitation can force the heart to work harder to do its job. The condition can lead to heart failure, sudden cardiac arrest, and death.

What is ring in heart surgery?

What is an annuloplasty ring? During annuloplasty, surgeons place a ring-like device around your heart valve. The ring may be mesh, metal or plastic. The ring mimics your heart valve’s natural movement and flexibility. It stays in place permanently and helps the valve open and close properly.

What is life expectancy after mitral valve replacement?

Median survival after MV ‐repair was 7.8 years, close to 8.5 years (95% CI : 8.2–9.4) in the age‐matched UK population (ratio 0.9). Rate of re‐operation for MV ‐dysfunction was 2.3% versus 2.5% (mitral valve replacement, P=1.0).

What are the warning signs of endocarditis?

Common signs and symptoms of endocarditis include:

• Aching joints and muscles.
• Chest pain when you breathe.
• Fatigue.
• Flu-like symptoms, such as fever and chills.
• Night sweats.
• Shortness of breath.
• Swelling in your feet, legs or abdomen.

Can you fully recover from endocarditis?

In many cases of endocarditis, antibiotics alone can cure the infection. However, in about 25-30 percent of patients with IE, surgery is needed during the early acute phase of infection due to severe valve leakage or failure to control the infection with antibiotics.

What is ring dehiscence rate in mitral annuloplasty?

CONCLUSION Annuloplasty ring dehiscence remains a rare but severe complication of heart valve surgery. In mitral annuloplasty ring repair, dehiscence rate has been found to significantly vary across types of rings, with rigid ring leading to more elevated rates when compared to flexible rings.

Is re-do mitral valve surgery to correct ring dehiscence feasible?

Re-do mitral valve surgery to correct ring dehiscence may not be feasible for patients at high risk of operative mortality or serious morbidity.

Which annuloplasty rings are best for mitral valve repair?

CONCLUSIONS Although rigid, semi-rigid and flexible annuloplasty rings provide acceptable valve repair outcomes, mitral annuloplasty ring dehiscence is clinically more common among rigid rings. Understanding the multifactorial nature of ring dehiscence will help in identifying the patients at high risk and improve their clinical outcomes.

What is non-ischaemic mitral regurgitation?

Dehiscence rate by pathology Studies were classified based on the causative pathology of regurgitation into ischaemic and non-ischaemic. Non-ischaemic included degenerative, functional, rheumatic, infectious and congenital mitral regurgitation.
