Dobutamine stress cardiac magnetic resonance role in patients with anomalous aortic origin of coronary arteries
Authors' conclusion
dsCMR is a reliable test for the evaluation of myocardial ischaemia in AAOCA, especially for those with intramural course, ischaemic LGE, and previous ACS episodes. Although rare, older patients may have a myocardial ischaemic scar without alteration of ventricular function.
Study context
- Population
- Anomalous Aortic Origin of Coronary Arteries (AAOCA) patients who underwent dobutamine-stress cardiac magnetic resonance (dsCMR), regardless of age, enrolled from 2015 to 2024AAOCA patients who underwent dsCMR
- Participants
- 100 patients
- Outcome
- Inducible myocardial ischaemia (positive dsCMR)
Main finding
As reported in the abstract
dsCMR positive
14 cases
Observational data: associations, not effects.
Further findings
Factors associated with inducible ischaemia
- Intramural course, ischaemic late gadolinium enhancement (LGE) and history of acute coronary syndrome (ACS) significantly associated with inducible ischaemia
Ischaemic LGE within the AAOCA territory
- Patients with small areas of ischaemic LGE
- Nine patients (9%)
- Patients with ischaemic LGE were older with a higher incidence of arterial hypertension, smoking habits and previous ACS episodes
