Echocardiography is the standard for follow-up of prosthetic heart valve (PHV) function, but has several well-known limitations. (shda.org.au)
CT is prone to artefact in older valves and showed no advantage over echocardiography for detection of vegetations or periprosthetic regurgitation. (shda.org.au)

The two most common valvular disorders in older adults are aortic stenosis and mitral regurgitation. (dan.org)

Oxidized low density lipoprotein ( oxLDL ) is often implicated in common, chronic conditions caused by inflammation like aortic valve stenosis. (abcentra.com)
This review explores a hypothesis that PD-1/PD-L1 blockade accelerates the progression of atherosclerosis and promotes plaque rupture, by synthesizing the evidence of vascular inflammation, as well as plaque progression, destabilization and rupture via T-cell activation and effector function.

People with prosthetic heart valves might be at elevated risk of infective endocarditis when they get invasive dental procedures, researchers concluded from a French national database study in BMJ , although the findings were inconclusive. (medpagetoday.com)

The slope of the regression of the aortic jet velocity on the time elapsed since the baseline study was used to define the rate of progression of stenosis. (eur.nl)
The annual progression of aortic jet velocity was 0.09 ± 0.15 m/s per year. (eur.nl)
Greater jet flow velocity with a gradient of less than 20 mm Hg is considered mild stenosis. (medscape.com)
Serially measured peak aortic jet velocity was the primary effect estimate. (elsevierpure.com)
In adjusted analyses, lower baseline peak aortic jet velocity and higher pretreatment LDL levels increased the effect of randomized treatment (p = 0.04 for interaction). (elsevierpure.com)
In conclusion, in a non-prespecified post hoc analysis, the efficacy of lipid-lowering therapy on impeding AS progression increased with higher pretreatment LDL and lower peak aortic jet velocity (SEAS study: NCT00092677). (elsevierpure.com)

The reduced rate of progression of atherosclerosis associated with intensive Statin treatment is significantly related to greater reductions in the levels of both atherogenic lipoproteins and C-reactive protein (CRP). (readabstracts.com)

are at increased risk for atherosclerosis, and more recently, psoriasis has been tied to an increased risk of aortic stenosis. (msdmanuals.com)

The changes in aortic valve function were reflected by dilation and hypertrophy of the left ventricle, as well as a decreased left ventricular ejection fraction. (nih.gov)
LF is a common finding within the aortic stenosis population and, in contrast to LV ejection fraction or mean pressure gradient, an independent predictor of all-cause and cardiovascular mortality. (omicsdi.org)

Routine endocarditis prophylaxis is indicated if there is prior history of endocarditis, prosthetic valve placement or for 6-months after complete repair of heart defect. (medscape.com)
The prognosis is especially poor in the setting of acute heart failure, for which aortic valve replacement provides the least benefit. (medscape.com)
The function of the aortic valve is to make sure that blood, once it has been pumped by the heart, does not flow back (to the left ventricle) and reaches the various tissues with the necessary volume and pressure. (portugalresident.com)
Together, these three essential signaling pathways help form the cardiac cushions and populate them with mesenchyme and, consequently, set off the cascade of events required to develop mature heart valves. (springer.com)
Furthermore, integration and cross-talk between these pathways generate highly stratified and delicate valve leaflets and septa of the heart. (springer.com)
Rabkin E, Aikawa M, Stone JR, Fukumoto Y, Libby P, Schoen FJ (2001) Activated interstitial myofibroblasts express catabolic enzymes and mediate matrix remodeling in myxomatous heart valves. (springer.com)
We don't know if reducing the workload on the heart can alter this process, protect the heart muscle, and possibly improve the lives of people with aortic stenosis. (otago.ac.nz)
It happens when heart valves wear out, hardening and restricting blood flow in the heart. (healthxchange.sg)
It can tell us if the heart valve is opening and closing properly, and if it is calcified or damaged," said Prof Yeo. (healthxchange.sg)
However, although it is a condition that is predominantly age-related, heart valves can wear out due to other causes such as infection, heart attacks and high blood pressure as well. (healthxchange.sg)
Two main problems can crop up in heart valves as we age: regurgitation or backflow, and stenosis. (healthxchange.sg)
As the valves are now tight, blood has problems travelling through or exiting the heart chambers. (healthxchange.sg)
In cases when the mitral valve (the heart valve between the left upper and lower chambers) is leaking, the left lower chamber of the heart keeps pumping harder to cope with the leakage of blood. (healthxchange.sg)
the heart chamber keeps leaking and the leaking valve makes it take longer for the heart to fill," said Prof Yeo. (healthxchange.sg)
Practicing good dental hygiene can also help since bad teeth can cause a heart infection, which can lead to valve damage. (healthxchange.sg)
When the blood flow through the aortic valve is reduced or blocked, the heart needs to work harder to pump blood. (abcentra.com)

Surgeon Q&A: Can A Patient Have A Healthy Heart With Multiple Leaking Valves? (heart-valve-surgery.com)
During his extraordinary career, Dr. Johnston has performed over 3,000 heart valve operations. (heart-valve-surgery.com)
Adam Pick is a heart valve patient and author of The Patient's Guide To Heart Valve Surgery. (heart-valve-surgery.com)
Having healthy heart valves is essential if your heart is to properly pump and circulate blood throughout your body. (dan.org)
Some people are born with structural anomalies in their heart valves or in the walls. (dan.org)
a heart murmur - detected when the heart is examined with a stethoscope - is often the first sign of valve damage. (dan.org)
The problem arises as a result of excess tissue and loose connective tissue in the heart's mitral valve, so that part of the valve protrudes down into the left ventricle during each contraction of the heart. (dan.org)
The trivial/trace aortic regurgitation you have is so common and often noted even in people without BAV, in fact trivial regurgitation is often found in the other valves of the heart and cardiologists don't worry about it when it is described as trivial or trace. (valvereplacement.org)
Connective tissue provides strength and flexibility to structures such as bones, ligaments, muscles, blood vessels, and heart valves. (iomcworld.org)
I probably get more inquiries from athletes with bicuspid aortic valve (BAV) than any other single heart problem. (athletesheart.org)

Mitral valve prolapse (MVP) may also be referred to as "click-murmur syndrome" or "floppy-valve syndrome. (dan.org)
It was only when I was 53 that a gastroenterologist I consulted about an abdominal issue heard the murmur of the valve and said I ought to see a cardiologist again and referred me to one. (valvereplacement.org)
Next, they'll use a stethoscope to detect the presence of the characteristic aortic stenosis murmur. (drraghu.com)

Variables associated with aortic stenosis and regurgitation progression, adjusted by follow-up time, were presence of raphe, hypertension and dyslipidemia and basal valvular dysfunction, respectively. (gencat.cat)

Currently, the use of new-generation devices and the growing attention toward a careful pre-procedural planning have led to an improvement of procedural results, with outcomes nowadays comparable to tricuspid valves ( 16 , 17 ). (frontiersin.org)

The normal right and left aortic leaflets form at the junction of the ventricular and arterial ends of the conotruncal channel. (medscape.com)
As the left ventricle becomes less compliant, the diastolic pressure-volume loop shifts upwards and rotates counterclockwise, resulting in elevated left ventricular end-diastolic pressure ( Figure 65-1 (B)). Although forward flow is affected, there is little change to the other cardiac chambers as long as the mitral valve remains competent. (mhmedical.com)
Consequently, the atrial contribution to ventricular filling ("atrial kick") is critical in aortic stenosis. (mhmedical.com)

A congenitally bicuspid aortic valve has two functional leaflets. (medscape.com)
The bicuspid valve is composed of two leaflets or cusps, usually of unequal size. (medscape.com)
Of the valves without raphes, more than 30% of the leaflets were unequal in size. (medscape.com)
Postrheumatic aortic stenosis is another common cause of acquired aortic stenosis, and is a result of remote infection from group A streptococci that triggers an autoimmune process resulting in scarring of the valve leaflets. (medscape.com)
Regurgitation happens when the valve leaflets do not close completely, and blood flows back from the valve or leaks through the flaps. (healthxchange.sg)
Each valve consists of a set of flaps (also called "leaflets" or "cusps") that open and close to enable blood to flow in the correct direction. (dan.org)
To quickly review, individuals with BAV have an aortic valve with 2 unequal-instead of the usual 3 equal sized-leaflets. (athletesheart.org)
This can lead to stretching apart of the valve leaflets and leakage at the valve, known as regurgitation . (athletesheart.org)

Following are $250,000- 20 year term "range of cost" rates you can expect to pay if you have a bicuspid valve with no more than mild regurgitation and good health otherwise. (americanterm.com)

Getting life insurance with bicuspid aortic valve is not always difficult, but you must deal with an independent agent or broker who's familiar with cardiac issues and can offer you rates from all of the competitive insurance companies. (americanterm.com)

Defective valves may be either repaired or replaced by prosthetic valves. (dan.org)

The tricuspid valve, between the right atrium and the right ventricle. (dan.org)

At least half of all congenitally bicuspid valves have a low raphe, which never attains the plane of the attachments of the two commissures and never extends to the free margin of the conjoined cusp. (medscape.com)
Most bicuspid valves get progressively worse as you age and many will ultimately require an aortic valve replacement or repair. (americanterm.com)
