What is mild mitral regurgitation?
Mitral regurgitation occurs when, due to the defective closure of the heart's mitral valve, blood flows in the opposite direction to normal, proceeding from the left ventricle to the left atrium.
What does mild mitral regurgitation involve?
Mitral regurgitation is a condition in which a defect in closing the mitral valve causes some of the blood pumped from the left ventricle to flow back into the left atrium rather than go into the aorta, causing fatigue and breathing problems.
How is mitral regurgitation treated?
A tiny paper clip to bring the mitral valve flaps back together when it no longer holds as it should, and is inserted without resorting to open heart surgery but through a catheter: it is the most famous minimally invasive system for repairing the mitral valve and is called MitralClip.
Where does the murmur of mitral regurgitation radiate?
The main sign of mitral insufficiency is the holosystolic (pansystolic) murmur, best audible at the apex with the diaphragm of the stethoscope and with the patient in left lateral decubitus. In mild mitral regurgitation, the systolic murmur may be shorter or occurs late in systole.
What are the symptoms of the mitral valve?
To recognize the alteration of the regular functioning of the mitral valve, the symptoms to look for are the following:- systolic murmur.
- dyspnea.
- fatigue.
- reduced effort capacity.
- palpitations.
- swelling in the lower limbs.
- dizziness.

What are mitral valve diseases?
The most frequent cause is idiopathic myxomatous degeneration. Mitral valve prolapse is usually benign, but complications include mitral insufficiency, endocarditis, and rupture of the chord.
What happens when the mitral valve doesn't close well?
The mitral valve is defined as "insufficient" when it does not close well and consequently a part of the blood, which the left ventricle should expel towards the Aorta to supply all the organs, instead goes back into the atrial cavity.
What does mild mitral regurgitation mean?
Reading in 2 min. Mitral regurgitation occurs when, due to the defective closure of the heart's mitral valve, blood flows in the opposite direction to normal, proceeding from the left ventricle to the left atrium.
What does the mitral valve prevent?
The mitral valve opens to allow blood from the left atrium to fill the left ventricle and closes when the left ventricle contracts to pump blood only out into the aorta and not back into the left atrium.
How do you know if you have a heart murmur?
Malignant heart murmur can manifest itself in a number of ways, including:- increased or decreased appetite,
- chest pain,
- shortness of breath,
- dizziness,
- fainting,
- excessive sweating.
When to operate the mitral valve?
In case of mild mitral insufficiency, heart surgery is not necessary, but periodic cardiological checks. In the case of moderate or severe mitral insufficiency, repair or replacement of the valve is necessary.
When should the mitral valve be replaced?
Replacement should be arranged when repairs are unable to ensure healing. This happens when, due to a rheumatic disease, the mitral area is so damaged that it has to be replaced with an artificial valve prosthesis.
How long does the mitral valve replacement surgery take?
The surgery to correct mitral insufficiency lasts one hour: from preparation to suturing the incision. Several advantages: reduced bleeding, lower risk of infections, such as hospitalization times (you go home in a week).
What is aortic insufficiency?
Aortic regurgitation refers to incontinence of the aortic valve that causes retrograde flow from the aorta to the left ventricle during diastole.
How many people suffer from mitral regurgitation?
One of these is mitral insufficiency, a defect in the heart's mitral valve closure that affects 250.000 people in Europe every year.
What life expectancy after aortic valve replacement?
Not only did it also emerge that patients operated on with Ross's technique have a life expectancy of 35 years and a life expectancy without future cardiac events of 26 years.
What does mild aortic regurgitation mean?
Aortic regurgitation is an abnormal condition in which the heart's aortic valve (one of the four heart valves) malfunctions, allowing oxygenated blood to flow back from the aorta to the left ventricle.
What is mild tricuspid regurgitation?
Tricuspid regurgitation is a backflow of blood through the tricuspid valve with each right ventricular contraction. Tricuspid regurgitation is caused by pathologies that thicken the right ventricle. Symptoms are vague, such as weakness and fatigue.
What is pulmonary regurgitation?
Pulmonary regurgitation is the backflow of blood through the pulmonary valve whenever the right ventricle relaxes. Usually it does not give rise to symptoms. Diagnosis is made by physical examination, while echocardiography is used to confirm the diagnosis.
How does mitral prolapse occur?
Mitral valve prolapse (PVM) or mitral valve prolapse consists of a malfunction in the closure of the valve that controls, allowing or preventing its passage, the flow of blood that from the left atrium, when the heart contracts (systole), passes into the left ventricle.
How is the mitral valve replaced?
Mitral valve replacement requires the implantation of a prosthetic valve which will completely replace the function of the diseased valve. Valve prostheses are divided into two large "families": mechanical; biological.
How many hours does the heart surgery last?
A first operation takes about three hours, but can take even longer in the case of complex operations. However, three hours are generally the time required for the heart surgeon to technically perform the operation.
How is heart valve replacement performed?
The heart is stopped and a heart-lung machine replaces heart and lung function. Then an incision is made in the descending aorta to identify the aortic valve. The damaged aortic valve is removed and replaced with the artificial valve.
How long does aortic valve repair take?
The replacement of the aortic valve or its repair is an operation that can last from 3 to 5 hours, therefore very long. The most time-consuming operations are the "open heart" ones.
How is tricuspid insufficiency treated?
The most popular tricuspid valve repair technique is annuloplasty with a prosthetic ring.
