Cardiovascular examination for MRCP PACES

The patient was a middle-aged man who was propped up in bed. He had an oxygen mask on. The fact that he appeared breathless made the trainees suspect that the patient may have left ventricular failure. He was of average height and weight.
On examination of his head he had flaring of his alae nasi, which gave the trainees further evidence of dyspnoea.
On examination of his hands there was clubbing which immediately brought up the suspicion of infective endocarditis.
His pulse rate was 90 beats per minute regular in rhythm. It was a large volume pulse and it was collapsing in nature. Sinus rhythm with a collapsing pulse made the trainee suspect that the patient had aortic regurgitation. Careful examination of the character of the brachial pulse revealed a Bisferiens pulse. This brought up the diagnosis of mixed aortic valve disease.
On examination of the neck the jugular venous pressure was elevated. the predominant wave was a systolic wave causing outward distension of the vein. The trainee though this was a V wave indicating tricuspid regurgitation. The trachea was in the midline.
On examination of the praecordium, the apex was palpable in the 6th intercostal space in the anterior axillary line. It was diffuse in nature. With the trachea in the midline the apex being palpable in the 6th intercostal space in the anterior axillary line indicated dilatation of the heart rather than mediastinal displacement. This would be in keeping with the suspicion of aortic regurgitation although it was not thrusting in nature.
On auscultation the first heart sound was soft suggesting mitral regurgitation.
The second heart sound was soft in keeping with aortic stenosis.
There was an ejection systolic murmur radiating to the neck and a blowing, decrescendo early diastolic murmur at the left sternal edge. Confirming our suspicion of mixed aortic valve disease. There was a blowing pan-systolic murmur at the mitral area that increased in intensity during expiration adding further evidence to the earlier suspicion that the patient had mitral valve disease (tricuspid regurgitation would have made the murmur increase in inspiration)
On auscultation of the ling bases there were fine late inspiratory crepitations in keeping with the earlier suspicion that the patient had left ventricular failure.
The trainee was then asked to listen over the femoral artery.
There was a systolic and diastolic bruit over the femoral artery, which confirmed the suspicion that the patient had aortic regurgitation.
Diagnosis
Mixed aortic valve disease (dominant regurgitation)
Mitral regurgitation
Tricuspid regurgitation
Possible infective endocarditis
Revision Tips
Revise character of the pulse (ACES for PACES page 194)
Revise differentiation of mixed valve disease (ACES for PACES pages 220-221)
Revise abnormalities of the femoral artery (ACES for PACES pages 223-224)
