Index 627 HISTORY
1. Chest pain: exertional, at rest (when angina is present, comment on the Canadian Cardiovascular
Angina class, p. 42).
2. Shortness of breath: exertional, at rest (when dyspnoea is present, comment on the New York Heart
Association class, p. 2), paroxysmal nocturnal dyspnoea.
3. Palpitations (see pp 35-6)
4. Dizziness, pre-syncope, syncope.
5. Swelling of feet. EXAMINATION OF THE CARDIOVASCULAR SYSTEM
1. Introduce yourself: 'I am Dr/Mr/Ms ............ May I examine your heart?'.
2. Ensure adequate exposure of the precordium: 'Would you take your top off, please?'. However, be
sensitive of the feelings of female patients.
3. Get the patient to sit at 45 degrees - use pillows to support the neck.
4. Inspection: comment on the patient's decubitus (whether he or she is comfort-able at rest or obviously
short of breath); comment on malar flush (seen in mitral stenosis).
5. Examine the pulse: rate (count for 15 s), rhythm, character, volume; lift the arm to feel for the
collapsing pulse. Feel the other radial pulse simultaneously.
6. Comment on the scar at antecubital fossa (cardiac catheterization scars).
7. Look at the tongue for pallor, central cyanosis.
8. Look at the eye for pallor, Argyll Robertson pupil.
9. Examine the jugular venous pulse: comment on the wave form and height from the sternal angle.
Check the abdominojugular reflux.
10. Comment on any carotid pulsations (Corrigan's sign of aortic regurgitation).
11. Examine the precordium: comment on surgical scars (midline sternotomy scars, thoracotomy scars
for mitral valvotomy may be missed under the female breast).
12. Feel the apex beat - position and character.
13. Feel for left parasternal heave and thrills at the apex and on either side of the sternum.
14. Listen to the heart, beginning from the apex: take care to palpate the right carotid pulse
simultaneously so that the examiner notices that you are timing the various cardiac events.
· Always comment on the first and second heart sounds. Mention any additional heart sounds (Am J Med
1959; 27: 360).
· If you do not hear the mid-diastolic murmur of mitral stenosis, make sure you listen to the apex in the left
lateral position with the bell of the stethoscope.
· If you hear a murmur at the apex, ensure that you get the patient to breathe in and out - the examiner
will be observing whether or not you are listening for the variation in intensity with respiration.
· If you hear a pansystolic murmur, listen at the axilla (mitral regurgitant murmurs are conducted to the
15. Using the diaphragm of your stethoscope, listen at the apex, below the sternum, along the left
sternal edge, the second right intercostal space and the neck (for ejection systolic murmur of aortic
stenosis, aortic sclerosis).
16. Request the patient to sit forward and listen with the diaphragm along the left sternal edge in the 3rd
intercostal area with the patient's breath held in expiration for early diastolic murmur of aortic
17. Tell the examiner that you would like to do the following: · Listen to lung bases for signs of cardiac
failure. · Check for sacral and leg oedema.
· Examine the liver (tender liver of cardiac failure), splenomegaly (endocarditis).
· Check the blood pressure.
· Check the peripheral pulses and also check for radiofemoral delay.
The New York Heart Association classification of dyspnoea: Class l
Asymptomatic (shortness of breath on unaccustomed exertion).
· Class l
l: There is slight limitation of physical activity and patients develop shortness of breath on
· Class III
Marked limitation of physical activity; patients develop shortness of breath on activities of
daily living such as having a shower, etc.
· Class IV
: Inability to carry out physical activity; shortness of breath at rest.
Rene Theophile Hyacinthe Laennec invented the stethoscope in 1816 and reported his early experience
with auscultation in a two-volume book published 3 years later (Laennec RTH 1821 A Treatise on the
Diseases of the Chest. London: T and G Underwood. Translated by and with a preface and notes by
British physician Sir John Forbes (1787-1861) is best remembered for popularizing the stethoscope
among English-speaking doctors. Forbes was born in Banff in the north east of Scotland. He studied at
Marischal College, Aberdeen, before he went to Edinburgh where he received his medical education.
Forbes translated Laennec's monograph in English in 1821 and published his own book on the subject in
1824 (Forbes J 1824 Original Cases with Dissections and Observations Illustrating the Use of the
Stethoscope and Percussion in the Diagnosis of the Diseases of the Chest. London: T and G
Underwood). The latter included a brief biographical sketch of the Austrian physician Leopald
Auenbrugger and the first English translation of his essay (which was in Latin) on percussion. It also
contained a summary of Parisian physician Victor Collin's recent manual on cardiac physical diagnosis.
This patient developed dyspnoea and orthopnoea during pregnancy, please examine her.
This 55-year old patient has atrial fibrillation, please perform the relevant clinical examination. SALIENT FEATURES
· Symptoms of left-sided heart failure: exertional dyspnoea, orthopnoea, paroxysmal dyspnoea.
· Less frequent symptoms: haemoptysis, hoarseness of voice, symptoms of right-sided failure (these
symptoms are somewhat more specific for mitral stenosis).
· Obtain a history of rheumatic fever in childhood. Examination
· Pulse regular or irregularly irregular (due to atrial fibrillation). · Jugular venous pressure (JVP) may be
raised. · Malar flush.
· Tapping apex beat in the 5th intercostal space just medial to midclavicular line. · Left parasternal heave
(indicating right ventricular enlargement). · Loud first heart sound.
· Opening snap (often difficult to hear; a high-pitched sound that can vary from 0.04 to 0.10 s after the
second sound, and is best heard at the apex with the patient in the lateral decubitus position).
· Rumbling, low-pitched, mid-diastolic murmur - best heard in the left lateral position on expiration. In
sinus rhythm there may be presystolic accentuation of the murmur. If you are not sure about the
murmur, tell the examiner that you want the patient to perform sit-ups or hop on one foot to increase
the heart rate. This will increase the flow across the mitral valve and the murmur is better heard.
· Pulmonary component of second sound (P2) is loud.
Remember. The signs of pulmonary hypertension include loud P2, right ventricular lift, elevated neck
veins, ascites and oedema. This is an ominous sign of the disease progression because pulmonary
hypertension increases the risk associated with surgery (Bt Heart J 1975; 37: 74-8).
· In patients with valvular lesions the candidate would be expected to comment on rhythm, the
presence of heart failure and signs of pulmonary hypertension.
· In atrial septal defect, large flow murmurs across the tricuspid valve can cause mid-diastolic
murmurs. The presence of wide, fixed splitting of second sound,
absence of loud first heart sound, and an opening snap and incomplete right bundle branch block should
indicate the correct diagnosis. However, about 4% of patients with atrial septal defect have mitral
stenosis, a combination called Lutembacher's syndrome. DIAGNOSIS
This patient has mitral stenosis (lesion) which is almost always due to rheumatic heart disease
(aetiology), and has atrial fibrillation, pulmonary hypertension and congestive cardiac failure (functional
What is the commonest cause of mitral stenosis?
Rheumatic heart disease. What is the mechanism of tapping apex beat?
It is due to an accentuated first heart sound. What does the opening snap indicate?
The opening snap is caused by the opening of the stenosed mitral valve and indicates that the leaflets are
pliable. The opening snap is usually accompanied by a loud first heart sound. It is absent when the valve
is diffusely calcified. When only the tips of the leaflets are calcified, the opening snap persists. What is the mechanism of a loud first heart sound?
The loud first heart sound occurs when the valve leaflets are mobile. The valve is open during diastole
and is suddenly slammed shut by ventficular contraction in systole. What is the mechanism of presystolic accentuation of the murmur?
In sinus rhythm it is due to the atrial systole which increases flow across the stenotic valve from the left
atrium to the left ventricle; this causes accentuation of the loudness of the murmur. This may also be
seen in atrial fibrillation and is explained by the turbulent flow caused by the mitral valve starting to close
with the onset of ventricular systole. This occurs before the first heart sound and gives the impression of
falling in late diastole; it is, however, due to the start of ventricular systole. What are the complications?
· Left atrial enlargement and atrial fibrillation.
· Systemic embolization, usually of the cerebral hemispheres.
· Pulmonary hypertension.
· Tricuspid regurgitation.
· Right heart failure. How does one determine clinically the severity of the stenosis?
· The narrower the distance between the second sound and the opening snap, the greater the severity.
The converse is not true. (Note. This time interval between the second sound and opening snap is
said to be inversely related to the left atrial pressure.)
in tight mitral stenosis the murmur may be less prominent or inaudible and the findings may be
primarily those of pulmonary hypertension. ADVANCED-LEVEL QUESTIONS
What are the investigations you would perform?
Broad bifid P wave (P mitrale); atrial fbrillation in advanced disease.
· Congested upper lobe veins.
· Double silhouette due to enlarged left atrium.
· Straightening of the left border of the heart due to prominent pulmonary conus and filling of the
pulmonary bay by the enlarged left atrium.
· Kerley B lines (horizontal lines in the regions of the costophrenic angles).
· Uncommonly the left bronchus may be horizontal due to an enlarged left atrium.
· Mottling due to secondary pulmonary haemosiderosis.
2D and Doppler echocardiography is the diagnostic tool of choice for assessing the severity of mitral
stenosis and for judging the applicability of balloon mitral valvotomy (N Engl J Med 1997; 337: 3241).
· It is able to identify restricted diastolic opening of the mitral valve leaflets due to 'doming' of the anterior
leaflet and immobility of the posterior leaflet.
· It also allows assessment of the mitral valve apparatus and left atrial enlargement. · Echocardiography
usually permits an accurate planimetric calculation of the valve area (Am J Cardiol 1979; 43: 560-8).
· It can also be used to assess the severity of stenosis by measuring the decay of the transvalvular
gradient or the 'pressure half-time', an empirical measurement (BrHeartJ 1978; 40: 13140).
· The mean transmitral gradient can be accurately and reproducibly measured from continuous wave
Doppler signal across the mitral valve with the modified Bernoulli equation.
· The mitral valve area can be non-invasively derived from Doppler echocardio-graphy with either the
diastolic half-time method or the continuity equation. The continuity equation should be used when
the area derived from the half-time does not correlate with the mean transmittal gradient.
· Doppler also allows estimation of pulmonary artery systolic pressure from the TR velocity signal and
assessment of the severity of concomitant MR or AR.
· Trans-oesophageal echocardiography is not required unless a question about diagnosis remains
after transthoracic echocardiography.
· Shows raised right heart pressures and an end-diastolic gradient from pulmonary artery wedge
pressure (or left atrium if trans-septal puncture has been done) to the left ventricle.
· Left and right heart cardiac catheterization is indicated when percutaneous mitral balloon valvotomy
is being considered.
· Cardiac catheterization is also indicated when there is a discrepancy between Doppler-derived
haemodynamics and the clinical status of a symptomatic patient.
· Coronary angiography may be required in selected patients who need intervention.
· Exercise haemodynamics should be performed when the symptoms are out of proportion to the
calculated mitral valve gradient area. What is the normal cross-sectional area of the mitral valve?
It ranges from 4 to 6 em2; turbulent flow occurs when this area is less than 2 cm2. What is the area in 'tight' mitral stenosis?
It is usually less than 1 cm2 and consequently the gradient across the valve is >10 mmHg. How would you manage the patient?
· Asymptomatic patient in sinus rhythm: prophylaxis against infective endocarditis only.
· Mild symptoms: diuretics to reduce left atrial pressure and therefore symptoms.
· Atrial fibrillation: (1) rate control (digitalis, beta-blocker or calcium channel blocker); (2)
anticoagulants (Eur Heart J 1988; 9: 291-4).
· Moderate to severe symptoms or pulmonary hypertension is beginning to develop: mechanical relief
of valve stenosis including (1) balloon valvotomy (N Engl J Med 1994; 331: 961-7; Br Heart J 1988;
60: 299-308) - percutaneous mitral balloon valvuloplasty is usually the procedure of choice when
there is a non-calcified pliable valve; (2) surgery. What are the indications for surgery?
· Patients with severe symptoms of pulmonary congestion and significant mitral stenosis.
· Patients with pulmonary hypertension or haemoptysis, even if minimally symptomatic.
· Recurrent thromboembolic events despite therapeutic anticoagulation. Which surgical procedures are used to treat mitral stenosis?
· Closed mitral valvotomy - involves the use of mechanical dilators, inserted through the apex of the
left ventricle. It is complicated by mitral regurgitation, systemic embolization and restenosis.
· Balloon valvuloplasty (a form of closed commissurotomy) - percutaneous trans-septal balloon mitral
valvotomy (or valvuloplasty). Remember, percutaneous balloon dilatation of the mitral valve is a
useful option in patients who are unable to undergo cardiac surgery, as in late pregnancy or when too
ill (severe respiratory disease, non-mitral cardiac disease, multiorgan failure).
Requires cardiopulmonary bypass and allows surgical repair of the valve under direct vision, resulting in
more effective and safer valvotomy than the closed procedure.
Entails risks including thromboembolism, endocarditis and primary valve failure. What factors determine the success of balloon valvuloplasty?
