Description

  • 49 years old man who presented at the outpatient clinic for a regular check-up.
  • He was asymptomatic, smoker, without any comorbidities and with a familial history free from cardiovascular events.
  • The physical examination revealed normal cardiac sounds plus a diastolic murmur at the basis of the heart, arterial blood pressure 130/70mmHg and heart rate of 64 beats per minute.
  • The electrocardiogram revealed normal sinus rhythm with no repolarization abnormalities.
  • Subsequently, the patient underwent transthoracic echocardiography examination.

Clinical case information

PLAX views

The PLAX image Showed slightly dilated left ventricle with normal systolic function (LVEDD 63mm, LVESD 41mm, FS 36%, EF 60%) severe dilatation of ascending aorta and aortic root (63mm) resulted in eccentric aortic regurgitation

Thus, more advanced techniques as proximal isovelocity surface area (PISA), were needed for the precise evaluation of the regurgitation due to its eccentricity (regurgitant volume 40-45ml).

Conclusion

Finally, aortic aneurysm accompanied by a moderate to severe eccentric aortic regurgitation was diagnosed and the patient was referred to a cardio surgeon for a combined surgery of aorta and aortic valve replacement.
