6 Mixed aortic valve lesion

Instruction

Examine this patient’s heart.

Examine this patient’s cardiovascular system.

Examine this patient’s pulse.

Salient features

• Pulse may be bisferious, small volume or large volume depending on the dominant lesion

• There is a displaced apex beat (remember a small LV is inconsistent with chronic severe aortic regurgitation)

• Early diastolic murmur of aortic regurgitation (Fig. 6.1)

• Ejection systolic murmur of aortic stenosis

• Proceed by telling the examiner that you would like to check the BP, in particular to determine the pulse pressure (systolic minus diastolic pressure).

Fig. 6.1 Phonocardiogram of the murmurs present in a patient with valvar aortic stenosis and regurgitation. Note the diamond-shaped systolic murmur peaking in early to midsystole and the high-frequency, lower-intensity murmur throughout diastole. 2 R.I.S., second right intercostal space; SM, systolic murmur; DM, diastolic murmur; 1, first heart sound, 2, second heart sound.

Diagnosis

This patient has mixed aortic stenosis with aortic regurgitation (lesion) caused by rheumatic heart disease (aetiology). He has a dominant stenosis and is in cardiac failure (functional status).
