Angiography

A medical imaging technique using x-rays and a contrast dye that allows Dr. Kiesz to evaluate if there are any blockages or narrowings in the arteries.

Angioplasty

A minimally invasive technique that involves a tiny balloon device which is used to push the soft plaque collected at the blockage of an artery to create a larger diameter and improve blood flow.

Ankle Brachial Index (ABI)

A test that compares blood pressures between the upper and lower limbs. Lower blood pressure in the legs may indicate blocked arteries due to peripheral artery disease.

Aortogram

The image resulting from placement of a catheter in the aorta and injection of contrast material while taking x-rays of the aorta, which is the main artery of the body originating from the heart.

Arteriogram/Angiogram

The film or image of blood vessels.

Atherectomy

A minimally invasive technique that uses a tiny blade-like device that cuts away plaque buildup in blocked or narrowed arteries.

Atrium

One of two upper chambers of the heart. The left atrium receives blood from the pulmonary (lung) circulation while the right atrium receives blood from the venous circulation. The blood is then passed on to the ventricles (lower chambers of the heart).

Catheter

A thin and flexible tube made from medical grade materials serving a broad range of functions. Catheters are medical devices that can be inserted in the body to treat diseases or perform a surgical procedure.

Electrocardiogram (ECG or EKG)

A graph (voltage versus time) of the electrical activity of the heart using electrodes placed on the skin. Changes in normal ECG patterns indicate cardiac abnormalities, such as heartbeat rhythm disturbances or poor blood flow of the coronary artery.

Intravascular Ultrasound (IVUS)

A medical imaging technique using a specially designed catheter with a miniaturized ultrasound probe attached to the end of the catheter. It produces an image of an artery to determine if there is blockage and if so, what type of plaque is causing it.

Renal

Relating to the kidneys, i.e. “Renal failure”.

Stent

A metal or plastic tube placed in the artery or blood vessel to keep the passageway open and ensure blood flow.

Stenosis

Abnormal narrowing of a blood vessel that results in poor blood flow.

Ventricle

One of the two main chambers near the bottom of the heart that collect and expel blood received from one of the atria (upper chambers of the heart).
