Mortality and morbidity thought
leaking heart valve
are an important part of cardiovascular pathology. The main changes
in the study of leaking heart valve involves an evaluation of their
function and etiology.
So, rheumatic etiology is declining, while the degenerative and ischemic etiology is growing.
Clinical evaluation methods have the same value (family history,
physical examination), but some paraclinical methods ( cardiac
ultrasound and Doppler) have an important role.
Types of leaking heart valve
Leaking heart valve may occur at the four heart valve: mitral valve, aortic valve, pulmonary valve and tricuspid valve.
The most common type of
leaking heart valve
is mitral regurgitation. It is characterized by regurgitation of blood
in systole ( contraction of heart) from the left ventricle into the left
atrium. There are two causes of mitral regurgitation: acute and
chronic. The etiology of mitral regurgitation can be inflammatory, but
also degenerative and structural. Chronic mitral regurgitation lead to
expansion of left atrium. Echocardiography provides important
information in mitral regurgitation.
Another type of leaking heart valve is aortic regurgitation. It is
incomplete closure of aortic valve in diastole (relaxation of heart).
Aortic valves are affected primary by acute articular rheumatism,
infectious endocarditis and degeneration and it can be acute or chronic.
Two other leaking heart valve are tricuspid regurgitation and
pulmonary regurgitation. Tricuspid regurgitation is characterized by
regurgitation of blood in systole from the right ventricle into the
right atrium because of the incomplete closure of the tricuspid orifice.
Leaking heart valve symptoms
Symptoms of patients with
leaking heart valve depends on
regurgitation grade and how to install (suddenly or gradually). Patients
with small regurgitation can be asymptomatic. There are some common
symptoms to the patients with leaking heart valve:
- dyspnea on effort (shortness of breath or air hunger);
- cough;
- angina pectoris on effort (chest pain on effort) or at rest;
- heart murmur;
- heart palpitations (heart beats more than 90 per minute);
- asthenia and adinamie;
- fatigue;
- rarely may occur syncope;
- pale skin on clinical examination.
Leaking heart valve diagnosis
Positive clinical diagnosis is based on present of heart murmur
(systolic or diastolic) with different characters. Most used methods for
diagnosis leaking heart valve are echocardiography, chest radiography, electrocardiography and Doppler exam.
Treatment and evolution of patients with leaking heart valve
Treatment of asymptomatic patients with leaking heart valve is not
necessary. To the patients with symptoms should avoid exercise and salt.
There are also treatments with drugs and surgery for leaking heart
valve.
Evolution and prognosis of leaking heart valve depend on the
importance blood reflux, of how to install (acute or chronic) and of the
etiology. Patients with small or average regurgitation may remain
asymptomatic a long time, but patients with complications (infectious
endocarditis, atrial fibrillation) have obvious symptoms. Patients with
acute leaking heart valve have serious prognosis.
