Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Subjects were recruited from patients presenting to the cardiac catheterization laboratory for scheduled elective percutaneous coronary intervention. Subject's medical history and angiographic coronary anatomy were used to evaluate eligibility.

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Technical limits of the prototype device factored into the data set reduction(28 patients).Data made available to evaluate handling of the device(30 patients) could not be prospectively evaluated for the primary endpoint of Spectral Similarity.
