Standard vs. 3-Dimensional Coronary Angiography: a Paired Comparison

Status Completed

Clinical Trial Summary

Aim of this study is to evaluate whether the length of coronary segments, assessed by an experienced operator, using the "optimal view" of standard 2-dimensional coronary angiography, is over/underestimated with respect to the one evaluated automatically with the help of a 3-dimensional coronary reconstruction model. Moreover, both techniques are compared with an "in-vivo" surrogate of the real length of the coronary segment under evaluation, i.e. an intra-coronary marker guide-wire, which is a wire with markers placed at fixed and known distance along its length in its distal (intra-coronary) part. Two hypotheses are tested: (1) the length of a coronary segment evaluated with a standard 2-dimensional "optimal view" over/underestimates the length assessed by a 3-dimensional coronary model that automatically detects the least foreshortened length of the segment under evaluation, and (2) the 3-dimensional model approximates more closely than standard 2-dimensional angiography, the real length of the segment detected by the marker guide-wire.

Clinical Trial Description

The potential to improve the accuracy of the assessment of the coronary tree by means of 3-D modeling reconstruction may lead to an evaluation of the coronary artery anatomy that approximates more correctly the real anatomy, thus subsequently leading to a more tailored diagnosis and therapy for the patients with ischemic heart disease.

Aim of the current study is to assess whether a 3-D model of the coronary tree offers a less foreshortened and less operator-dependent evaluation of the length of the coronary arteries with respect to standard coronary angiography. Furthermore, for the first time "in-vivo", a comparison with the "real" length of the vessel will be performed using as "gold standard" an intra-coronary guide-wire with radiopaque markers at fixed and known distance one from the other along its distal part. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
