The patient was a middle aged female. She was propped up in bed and breathless. We asked the trainee what her thoughts were and she replied that in the context of a cardiovascular examination, breathlessness would suggest the patient had heart failure.
She was of average height and weight.
On examination of her head, the only abnormality seen was flaring of the alae nasi in keeping with the impression that the patient was in heart failure.
On examination of her hands there was no abnormality.
Her pulse rate was 90 beats per minute regular in rhythm and volume. The pulse was large in volume and collapsing in nature. This was a definite collapse and a good example. We went through the technique of demonstrating a collapsing pulse (ACES for PACES page 159) We discussed the causes of a collapsing pulse (ACES for PACES page 194) and the trainee concluded that in the context of the PACES examination, a collapsing pulse would most likely indicate aortic regurgitation.
There was no bisferiens pulse. This made mixed aortic valve disease less likely.
On examination of her neck it was noted that the jugular venous pressure was elevated about 5 cms above the manubriosternal angle. This was further evidence in favour of the impression that the patient had heart failure. In this patient a pulsation in the neck could also be exaggerated carotid pulsation , Corrigan’s sign ( ACES for PACES page 200 abnormalities of the carotid pulse)
Hence, it was important to differentiate between this and the jugular venous pulse. We went through how to analyse pulsations in the neck (ACES for PACES page 162)
The trachea was in the midline.
On examination of the chest it was noted that there were no deformities or pulsations of the praecordium. The apex beat was in the 6th left intercostal space in the anterior axillary line and it was thrusting in nature.
A displaced apex in the context of a trachea in the midline would suggest the heart was dilated (not mediastinal shift).
See ACES for PACES page 201-203 abnormalities of the apex beat
This was in keeping with the impression that the patient had aortic regurgitation.
The thrusting apex was also in favour of this diagnosis.
There was no parasternal heave and there were no thrills.
There was an ejection systolic murmur in the aortic area, which did not radiate and there was a decrescendo early diastolic murmur at the left sternal edge, which increased in intensity when the patient leaned forward and held her breath in expiration.
On auscultation of her lung bases bilateral basal crepitations were heard.
On auscultation over her femoral arteries a systolic bruit was heard.
Diagnosis:
Aortic regurgitation, sinus rhythm, heart failure
We went through the questions that could be asked in relation to this case.
First, what are the causes of aortic regurgitation and after that how does one assess severity (ACES for PACES page 216)
Next, how does one investigate the patient? (See planning investigation ACES for PACES pages 571-574)
How does one manage this patient? (See planning management ACES for PACES pages 574-577)
