Mitral valve insufficiency (regurgitation) is the condition characterized by backflow of the blood from the left ventricle to the left atrium during systole, due to mitral valve prolapse, rheumatic or ischemic heart disease, infective endocarditis, cardiomyopathy or mitral apparatus calcification. Depending primarily on the onset of the disease, acute or chronic, mitral valve insufficiency leads to various clinical pictures.
Presentation
Patients may be asymptomatic or may have manifestations like fatigue caused by reduced cardiac output, tachypnea or dyspnea, orthopnea, paroxysmal nocturnal dyspnea and hemoptysis due to pulmonary hypertension [1]. When atrial fibrillation due to left atrium dilatation occurs, most patients experience palpitations. In children, failure to thrive is an important hallmark of almost all serious heart conditions.
When mitral regurgitation happens abruptly, being caused by an acute accident like chordal or papillary muscle rupture due to myocardial infarction, compensatory mechanisms do not have time to install and symptoms are dramatic, as patients present with pulmonary edema or cardiogenic shock. In chronic severe mitral regurgitation, patients slowly progress to congestive heart failure and pulmonary edema [2].

If the condition persists, the patient can also develop atrial fibrillation and potentially congestive heart failure, leading to shortness of breadth, dizziness, chest pain, and fatigue. [myocor.com]
- Akinesia
Ischemic MR is characterized by restrictive mitral leaflet mobility due to dyskinesia or even akinesia of the ventricular wall which bears one or both papillary muscles, thus, extending the distance between the ventricular wall and the leaflets. [ncbi.nlm.nih.gov]
Workup
A clinical examination reveals a left atrial lift caused by the left atrium filling with blood during systole. The first heart sound is normal or diminished, while the second heart sound is split into early stages of the disease because the aortic valve closes early. The splitting interval diminishes as pulmonary hypertension starts [1]. A third sound caused by increased ventricular filling may also appear, while the pulmonary component of the second heart sound is accentuated if pulmonary hypertension has begun. Mitral valve prolapse is accompanied by an ejection systolic click.
The murmur caused by mitral regurgitation is best heard at the apex and radiates towards the axilla and subscapular area. It is usually pansystolic, but may also be presystolic in acute settings or telesystolic in mitral valve prolapse or papillary muscle dysfunction. The intensity decreases as the left ventricle dysfunction advances [2].
Peripheral pulse is sharp but has a small volume; atrial fibrillation presents late in the course of the disease and the characteristic pulse abnormality is noted. The dilated left atrium may compress the left main bronchus, leading to wheezing and, rarely, lung atelectasis and hyperinflation.
The postero-anterior radiography may show a normal aspect of the heart or enlarged left atrium and left atrial appendage; if mitral regurgitation begins abruptly, the X-ray shows signs of pulmonary edema with normal sized left atrium. The pulmonary edema might be more prominent in the right upper lobe [3]. Cardiomegaly is present in chronic regurgitations.
Echocardiography is the most valuable tool in assessing mitral regurgitation. Two-dimensional (2D) echocardiography is useful in measuring heart dimensions and characterizing the mitral apparatus while trying to identify the cause of the disease and associated abnormalities. Color flow echocardiography describes the direction of the flow [4]. Quantitative and semi-quantitative measurement methods should be used in evaluating disease severity [5].
Spectral Doppler (pulse and continuous) is useful in calculating the severity of the regurgitation (by measuring parameters such as vena contracta, proximal isovelocity surface area, and regurgitant fraction) and evaluating a possible concomitant mitral stenosis [5]. If doubt about severity persists, stress echocardiography and exercise testing should be performed [2].
Transesophageal echocardiography and heart catheterization are indicated in cases where heart anatomy is uncertain [6], whereas cardiac magnetic resonance imaging (MRI) is more accurate in determining ventricular function and size. Catheterization is also useful in grading the regurgitation [7].
Electrocardiography shows rhythm and conduction abnormalities, left atrial enlargement and right ventricular hypertrophy if pulmonary hypertension is present.
Brain natriuretic peptide has prognostic value in severe mitral regurgitation and can be used in risk stratification [8].
P Wave
- P Mitrale
Also, it may detect a dilated left atrium and ventricle and decreased left ventricular function.MOHAMMAD ALADAM 23. Electrocardiography: P mitrale is broad, notched P waves in several or many leads with a prominent late negative component to the P wave [slideshare.net]
Electrocardiography[edit] P mitrale is broad, notched P waves in several or many leads with a prominent late negative comp[[mb b [[]]]]onent to the P wave in lead V1, and may be seen in MR, but also in mitral stenosis, and, potentially, any cause of overload [en.wikipedia.org]
The most common finding is left atrial enlargement (P mitrale), but this finding disappears if the patient enters atrial fibrillation. Right heart strain may produce findings of right axis deviation and right ventricular hypertrophy on ECG. [healio.com]
Hypertrophy
- Left Ventricular Hypertrophy
In ICD-10-CM, the code for left ventricular hypertrophy is I51.7 Cardiomegaly. The heart is divided into right and left sides by a septum (a muscular wall). [aapc.com]
Eventually, these patients develop eccentric left ventricular hypertrophy and worsened contractility. EF can fall below 50% and regurgitant volume can exceed forward volume in severe MR. [openanesthesia.org]
The chronic compensated phase results in eccentric left ventricular hypertrophy. The combination of increased preload and hypertrophy produces increased end-diastolic volumes, which, over time, result in left ventricular muscle dysfunction. [emedicine.medscape.com]
Treatment
We found that although percutaneous treatment was effective at reducing mitral regurgitation, surgical treatment was more effective, as graded by an echocardiographic core laboratory. [nejm.org]
Mitral Valve Regurgitation Treatment The goals of treatment for mitral regurgitation are to limit or eliminate the leakage of your valve while providing symptom relief and improving the quality and longevity of your life. [upmc.com]
Treatment Treatment will depend on what symptoms you have, what condition caused the mitral valve regurgitation, how well the heart is working, and if the heart has become enlarged. [mountsinai.org]
Prognosis
The prognosis of these patients is good; however, sudden death, endocarditis, and progressive regurgitation occur rarely. [emedicine.medscape.com]
Mitral Valve Regurgitation Prognosis Prognosis for mitral valve regurgitation varies based on its severity, whether it be major or mild mitral valve regurgitation. Medication can ease symptoms, but cannot reverse mitral valve regurgitation. [baptisthealth.com]
