简要总结

The purpose of this prospective study is to compare point-of-care focused cardiac ultrasound (FOCUS) to thoracic computed tomographic angiography (CTA) in the measurement of ascending aortic dimensions. We hypothesize that FOCUS will demonstrate good agreement with CTA in the measurement of ascending aortic dimensions and accurately detect dilation and aneurysmal disease.

详细描述

Nonspecific chest pain is frequently encountered in the emergency department. Accounting for over 13,000 deaths annually, aortic aneurysmal disease is a potential cause of chest pain.There are multiple diagnostic imaging modalities in practice to interrogate the thoracic aorta, with the most common being computed tomographic angiography (CTA), trans-thoracic echocardiography (TTE) and trans-esophageal echocardiography (TEE), each with its own advantages and limitations. In the ED setting, point-of-care (POC) focused cardiac ultrasound (FOCUS) is increasingly being used as an adjunct to the emergency physician's (EP) workup of undifferentiated chest pain. Based on prior retrospective data FOCUS and CTA appear to have good agreement. This studies aims to confirm these findings through prospective evaluation

Specific Aims

Aim 1: To prospectively compare Point of Care (POC) Focused Cardiac Ultrasound (FOCUS) to thoracic computed tomographic angiography (CTA) in the measurement of ascending aortic dimensions.

Maximal diameter measurements of the ascending thoracic aorta by FOCUS will be compared to CTA. Bland Altman plots with 95% limits of agreement will be used to determine clinical and statistical significance.

Hypothesis: 95% limits of agreement between FOCUS and CTA will be within +/- 5 mm.

结局指标

主要结局

Maximal diameter measurements of the proximal ascending aorta by CTA and FOCUS

时间窗: during emergency department visit (estimated average 3-6 hours)

Maximal diameter measurements of the ascending thoracic aorta by FOCUS will be compared to CTA. Bland Altman plots with 95% limits of agreement will be used to determine clinical and statistical significance.

次要结局

  • Time to Emergency Department Disposition(estimated time frame 3-6 hours)
  • Number and percent probabilities of differential diagnosis((estimated time frame 0 -3 hours))
  • Time to diagnostic imaging(estimated time frame 0-6 hours)
