Coronary angioscopy

Introduction

SOurce Springimages

Coronary angioscopy is the current gold standard for the detection of intracoronary thrombus. In comparison with angioscopy; number of clinical studies have been reported the lack of sensitivity of coronary angiography to detect a coronary thrombus. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19]

Clinical use

Clinical use

  • Helpful tool to estimate plaque wall thickness
  • High resolution (10–50 ΞΌm)
  • Obtains good surface imaging (i.e., thrombus, color)
  • Provides forward viewing
Types of equipment

Types of equipment

Two types of modalities are available. A forward looking camera and a side looking camera.

Disadvantages

  • May cause vascular damage
  • Needs blood displacement
