ETIOLOGY AND PATHOLOGY


Rheumatic fever is the leading cause
less common etiologies of obstruction to left atrial
outflow:








congenital mitral valve stenosis
mitral annular calcification with extension onto the leaflets
systemic lupus erythematosus
rheumatoid arthritis
left atrial myxoma
infective endocarditis with large vegetations
pure or predominant MS occurs 40% of all patients
with rheumatic heart disease and a history of
rheumatic fever
lesser degrees of MS may accompany mitral
regurgitation (MR) and aortic valve disease
24
RHEUMATIC MS





the valve leaflets are diffusely thickened by fibrous tissue
and/or calcific deposits
mitral commissures fuse, the chordae tendineae fuse and
shorten, the valvular cusps become rigid, lead to narrowing
at the apex of the funnel-shaped ("fish-mouth") valve
initial insult to the mitral valve is rheumatic, later changes
may be a nonspecific process resulting from trauma to the
valve caused by altered flow patterns due to the initial
deformity
Calcification of the stenotic mitral valve immobilizes the
leaflets and narrows the orifice further
Thrombus formation and arterial embolization may arise
from the calcific valve itself, but in patients with atrial
fibrillation (AF), thrombi arise more frequently from the
dilated left atrium (LA), particularly the left atrial
appendage
25
PATHOPHYSIOLOGY






hemodynamic hallmark of MS: blood flows from the LA to
the left ventricle (LV) is propelled by an abnormally
elevated left atrioventricular pressure gradient
pulmonary venous and pulmonary arterial (PA) wedge
pressures = pulmonary compliance = to exertional
dyspnea
dyspnea are precipitated by clinical events that increase
the rate of blood flow across the mitral orifice = LA
pressure
the elevated LA and PA wedge pressures exhibit a
prominent atrial contraction and a gradual pressure
decline after mitral valve opening
In severe MS: pulmonary vascular resistance is
significantly increased, the pulmonary arterial pressure
(PAP) is elevated at rest and rises further during exercise,
often causing secondary elevations of right ventricular (RV)
end-diastolic pressure and volume
LV diastolic pressure and ejection fraction (EF) are normal
26
PULMONARY HYPERTENSION
passive backward transmission of the elevated LA
pressure
 pulmonary arteriolar constriction, triggered by LA and
pulmonary venous hypertension (reactive pulmonary
hypertension)
 interstitial edema in the walls of the small pulmonary
vessels
 organic obliterative changes in the pulmonary vascular
bed
 severe pulmonary hypertension results in RV
enlargement, secondary tricuspid regurgitation (TR) and
pulmonic regurgitation (PR), as well as right-sided heart
failure

APEX BEAT DISPLACEMENT
Patient AB: 7th LICS, MCL
 Lateral and/or inferior displacement of the apex
beat usually indicates cardiomegaly.
 May also be displaced by other conditions:

Pleural or pulmonary diseases
 Deformities of the chest wall or the thoracic vertebra

28
(+) ACCENTUATED S1

Mitral valve snaps shut more vigorously,
producing a louder S1
Blood velocity is increased-> anemia, fever,
hyperthyroidism, anxiety, and during exercise
 Mitral valve is stenotic

29
(+) DIASTOLIC MURMUR
Early diastolic
Begins with S2
Mid diastolic
Begins at clear
interval after S2
Late diastolic
(presystolic)
Begins immediately
before S1
30
(+) DIASTOLIC MURMUR
Heard with bell at apex, patient in left lateral
decubitus position
 Findings on examination



Low-frequency diastolic rumble, more intense in
early and late diastole, does not radiate; systole
usually quiet; palpable thrill at apex in late diastole
common; S1 increased and palpable at left sternal
border
Description
Narrowed valve restricts forward flow; forceful
ejection into the ventricle
 Often occurs with mitral regurgitation caused by
rheumatic heart fever or cardiac infection

31
LUNG FINDINGS
Occasional wheeze
 Musical respiratory sounds thaat may be audible
both to the patient and to others
 Suggests partial airway obstruction from
secretions, tissue inflammation, or a foreign
body.
 Wheezing is one of the manifestations of
pulmonary congestion (cardiac asthma).

ECHOCARDIOGRAM
Most specific and sensitive method of diagnosing and quantifying the
severity of mitral stenosis
Graphic outline of the heart's movement .
Two- dimensional (2-D) Echo is capable of displaying a cross-sectional
"slice" of the beating heart, including the chambers, valves and the
major blood vessels that exit from the left and right ventricle
Echo is often combined with Doppler ultrasound and color Doppler to
evaluate blood flow across the heart’s valves.
56
2D ECG: SIGNIFICANCE
Assess the heart’s function
Determine the presence of disease of the heart muscle, valves
and pericardium, heart tumors, and congenital heart disease
Evaluate the effectiveness of medical or surgical treatments
Follow the progress of valve disease
