This is a procedure performed using a multi-slice CT. The current multi-slice CT that exquisitely produces coronary artery images, is a 64-slice CT scanner.
This scanner has a special x-ray tube and rotation speed, capable of performing 3 rotations in a second. In each rotation, 64-slices are produced, giving us approximately 194 slices per second. This is the fastest scanner in the industry, currently. Speed is extremely important in the ability to "freeze" the heart. Since the heart is a rapidly moving structure, the only way to image structures within it, is if we can scan as fast as the heart beats or close enough.
All scans are gated to the ECG trace. This allows to position the data acquisition accurately in specific phases.
Using this modality the following procedures can be performed as part of a cardiac CT examination.
The applications of cardiac CT include the following : -
Detection and characterization of coronary artery occlusive lesions secondary to atherosclerosis, transplant arteriopathy, intimal dissection and vasculitis
Detection and characterization of coronary artery anomalies
Detection and characterization of coronary artery aneurysms
Coronary vein mapping
Characterization of cardiac chamber morphology and function
Characterization of native and prosthetic cardiac valves
Detection and characterization of congenital heart disease
Characterization of cardiac masses
Diagnosis of pericardial diseases
Detection and characterization of post-operative abnormalities
Who should get a cardiac CT done !
The following are situations in which a cardiac CT is of use : -
"To Rule Out Coronary Artery Disease"
The ability of cardiac CT to rule out coronary artery disease exceeds a predictive value of 99%. This means that when the study is reported to be normal, it will be normal. This makes it a more accurate test than stress-testing, stress-echocardiography, stress-thallium and stress-perfusion MRI. More importantly, the heart does not have to be stressed to get this information.
"To Rule Out Coronary Artery Disease" is an issue that often arises in the following situations : -
The Patient is Asymptomatic : -(i.e. there are no problems, such as chest pain or breathlessness, but coronary artery disease needs to be ruled out)
Family history of coronary artery disease
Persistent high triglyceride levels and other high risk factors such as smoking, diabetes, etc.
ECG abnormalities on a routine health check-up
Equivocal (plus/minus) abnormalities on a routine stress test, done prior to employment, insurance or as part of a routine health check-up
Moderate to severe hypertension
Prior to non-coronary surgery in the adult population, etc
Pre-ASD repair
Pre-valvular repair
Pre-tumor surgery
The Patient is Symptomatic : -(i.e. there is chest pain or breathlessness, but the physician / cardiologist is not convinced that there is coronary artery disease)
Cardiac CT is an excellent tool for assessing the status of bypass grafts.
Post-stent
For stents larger than 3mm in size, cardiac CT is an excellent tool for assessing in-stent lumen. For stents smaller than 2.5mm, the results are still equivocal.
Tumors
Cardiac CT is a good tool for assessing cardiac neoplasms
