- Planned elective CABG for coronary artery disease.
- CABG is the primary indication for surgery (but may include treatment of mild-moderate
- Age: ≥40 years.
- Technical feasibility of the cardiac CT exams: redo-CABG, significant
arrhythmia/mal-conduction, congenital conditions, severe valvular disease or
cardiomyopathy (to the extent that the CT acquisition is technically challenged),
inadequate understanding of the English language (to provide consent or follow
instructions during the exams).
- Overall safety: unstable clinical condition (clinical heart failure, unstable angina,
myocardial infarction <1 month prior).
- Radiation risk: pregnancy (cannot be ruled out), body weight >100kg.
- CT contrast medium-related: known allergy, renal failure
- Vasodilator related: known allergy, bronchial asthma requiring daily use of
bronchodilators, Mobitz II or 3rd degree AV block, sick sinus node disease, clinically
significant carotid artery narrowing, severe aortic stenosis or LVOT narrowing,
systolic blood pressure below 90mmHg, (continued) use of dipyridamole or
- Inability to provide informed consent.
