Summary

Routine cardiac catheterization can identify undiagnosed abdominal aortic aneurysms (AAA). This screening is inexpensive, easily performed, and should be a standard part of the procedure for patients with AAA risk factors.

Area of Science:

  • Cardiovascular Medicine
  • Vascular Surgery
  • Diagnostic Imaging

Background:

  • Routine screening for abdominal aortic aneurysms (AAA) is recommended by many authorities.
  • Patients undergoing cardiac catheterization frequently present with AAA risk factors.
  • The clinical utility of AAA screening during cardiac catheterization warrants evaluation.

Purpose of the Study:

  • To assess the effectiveness of screening for abdominal aortic aneurysms (AAA) during cardiac catheterization.
  • To determine if AAA can be incidentally detected during this common cardiac procedure.

Main Methods:

  • Prospective examination of the abdominal aorta in 127 patients undergoing cardiac catheterization.
  • Primary imaging technique: panning down during left ventriculography.

Related Experiment Videos

  • Secondary imaging: formal abdominal aortogram if catheter advancement was difficult.
  • Off-line analysis of aortic morphology and diameters.

    • Main Results:

    • Adequate visualization of the abdominal aorta was achieved in 99 patients (78%).
    • Previously undiagnosed, asymptomatic abdominal aortic aneurysms (AAA) were detected in 8% of patients.
    • Difficulty advancing the catheter during cardiac catheterization was an independent predictor of AAA presence (OR=11.1).

    Conclusions:

    • Cardiac catheterization provides an opportunity to identify undiagnosed abdominal aortic aneurysms (AAA).
    • Screening for AAA during cardiac catheterization is cost-effective and simple to implement.
    • Incorporating AAA screening into routine cardiac catheterization procedures is advisable.
