Key result
Coronary computed tomography angiogram successfully evaluated coronary anatomy and left ventricular function after a non-diagnostic stress scan, facilitating complication-free noncardiac surgery.
Why the study?
Does CCTA provide reliable preoperative cardiac evaluation in patients where stress MPS is non-diagnostic?

Does CCTA provide reliable preoperative cardiac evaluation in patients where stress MPS is non-diagnostic?
CCTA may serve as a feasible and reliable alternative for preoperative cardiac risk stratification when traditional stress imaging is non-diagnostic.
CCTA may enable preoperative evaluation after nondiagnostic stress imaging; leaves open need for prospective validation before routine use.
Preoperative assessment of the cardiac patients before noncardiac surgery is concern in the clinical practice of anesthesiologist, surgeon, and medical consultant. The preferred stress testing is exercise electrocardiogram (ECG) in patients who are able to exercise and have normal ECG; however, either stress myocardial perfusion scintigraphy (MPS) or stress echocardiography is necessary if further testing is appropriately indicated before surgery. Unfortunately, stress MPs or stress echocardiography is not widely available and has some limitations. Coronary computed tomography angiogram (CCTA) has demonstrated excellent diagnostic accuracy in detecting coronary artery disease and accurate left ventricle function measurement. CCTA seems to be feasible, reliable, and has strong potential of becoming sole screening test before surgery.

Ahmed Fathala (2011) conducted a case report in Preoperative cardiac evaluation (n=1). Coronary computed tomography angiogram (CCTA) vs. Stress myocardial perfusion scintigraphy (MPS) was evaluated on Perioperative cardiac complications. Coronary computed tomography angiogram successfully evaluated coronary anatomy and left ventricular function after a non-diagnostic stress scan, facilitating complication-free noncardiac surgery.
