What is a heart CT scan?

A cardiac computed tomography also may be called a coronary CT angiography, MSCT, CT, cardiac CT, coronary CTA or cardiac CAT scan

Your doctor may send you to a heart CT scan.  A traditional CT scan is an x-ray procedure that combines many x-ray images with the aid of a computer to generate cross-sectional views of the body. Cardiac CT uses the advanced CT technology with intravenous (IV) contrast (dye) to visualize your heart muscle and structures, coronary arteries, pulmonary veins, aorta, and pericardium (the sac around your heart).

Dr. Vidyasagar Kalahasti, staff cardiologist in our Section of Imaging states:

We use the cardiac CT for:   Diagnosis of blockages in the coronary arteries, assessment of pulmonary veins after ablation of atrial fibrillation, preoperative planning prior to repeat heart surgery,  and assessment of aortic aneurysm and pericardium.

The CT is a great test because:   Only a short time  is needed for the study to be completed,  it is noninvasive and  it provides excellent visualization of cardiovascular structures.

New technology is allowing us to also  use CT for:   planning prior to percutaneous heart valve implantation  and other interventional cardiac procedures.
