Invasive Right Anomalous Coronary Arteries Assessment: Intravascular Ultrasound and Adenosine vs Dobutamine Fractional Flow Reserve.

ABSTRACT:

Background

In the right anomalous aortic origin of a coronary artery (R-AAOCA), invasive fractional flow reserve during dobutamine (FFR_Dobutamine) allows to assess dynamic interarterial/intramural compression that may lead to ischemia. However, FFR_Dobutamine requires expertise and is procedurally complex. Therefore, a simpler alternative is needed, but it remains uncertain whether routine intravascular ultrasound (IVUS) and standard FFR during adenosine (FFR_Adenosine) can reliably determine hemodynamic relevance.

Objectives

This study aimed to compare the diagnostic accuracy of FFR_Adenosine and IVUS-based minimal lumen area (IVUS-MLA) against the reference standard of FFR_Dobutamine for identifying hemodynamically relevan
