Why the study?

Does videodensitometric quantitative angiography correlate better with intracoronary ultrasound than edge-detection angiography for measuring minimal luminal cross-sectional area after coronary interventions?

Population

150 patients who underwent successful balloon angioplasty (n=100) or directional atherectomy (n=50)

Comparison

Videodensitometric quantitative angiography and… vs Intracoronary ultrasound (ICUS)

Design

Cohort

Discussion

Member takes

Implication

VID may improve postintervention luminal assessment accuracy versus ED in complex lesions; leaves open need for outcome trials before changing practice.

Intervention

Videodensitometric quantitative angiography (VID) and edge-detection quantitative angiography (ED) before and after intervention

Comparator

Intracoronary ultrasound (ICUS)

Outcome

Correlation of minimal luminal cross-sectional area measurements between imaging techniquessurrogate

Videodensitometric quantitative angiography shows better agreement with intracoronary ultrasound than edge-detection angiography in assessing complex coronary lesions after angioplasty or atherectomy.
