Abdominal aortic aneurysm is a localized dilatation of the abdominal aorta exceeding the normal diameter by more than 50 percent. Two types of procedures include the open procedure and the endovascular procedure.

This 3D medical animation shows the coronary vessels in the heart and the different ways they may become blocked. The symptoms of acute coronary syndrome (ACS) are depicted. The animation finishes up with common treatments for acute coronary syndrome and heart attack.

An aortic aneurysm is abnormal bulging in the wall of the aorta running through the chest. The possible locations of aortic aneurysms and the formation of an aortic dissection are shown.

Aortic Valve Replacement is the surgical replacement of the aortic valve with an artificial valve.

Atherosclerosis is a disease in which fatty material, called plaque, can build up in the arteries and block the flow of blood. Atherosclerosis in the coronary arteries of the heart can cause a heart attack.

Atrial fibrillation is a type of arrhythmia, which is an abnormality in the pace or force of your heartbeat. If you have atrial fibrillation, the heart's upper chambers contract in a fast, twitchy fashion, resulting in an irregular, uncoordinated heartbeat.

A blood transfusion procedure begins with the IV placement, and ends with the monitoring of vital signs.

A heart with abnormal signals and atrial fibrillation is shown forming a blood clot which results in a stroke. Steps of the cardioversion procedure are depicted: the placement of EKG electrodes, the placement of cardioversion paddles, the delivery of shock to the chest and heart, and the restoration of normal electrical signals within the heart.

Carotid artery stenosis may cause a transient ischemic attack or a stroke, causing you to undergo carotid endarterectomy. The steps involved in a carotid endarterectomy are shown: the incision, the placement of clamps and shunt, and the removal of the plaque.

A cerebral aneurysm is a ballooning of an artery in the brain. This 3D medical animation describes how aneurysms form in the circle of Willis and how they can rupture. Symptoms and treatments such as surgical clipping and endovascular coiling are also explained.

This video demonstrates the step-by-step procedures for checking blood flow in the leg and performing a capillary refill test, after lower extremity (leg, hip) surgical procedures. Symptoms requiring a follow-up call to the surgeon are listed.

This video demonstrates the step-by-step procedures for checking blood flow in the arm and performing a capillary refill test after upper extremity (arm, shoulder) surgical procedures. Symptoms requiring a follow-up call to the surgeon are listed.

The buildup of plaque in an artery wall of the heart, blocking the flow of blood could cause you to undergo a coronary angiography procedure.

Coronary artery angiography (cardiac catheterization,) involves threading a catheter through the femoral artery to the left coronary artery. Dye is injected into the artery, which allows for a clot to be seen on an x-ray image.

Coronary artery bypass graft (CABG) procedure is used to bypass blocked coronary arteries: the internal thoracic artery from inside the chest wall, and the saphenous vein from the leg.

An echocardiogram is a test that uses sound waves to create a moving picture of the heart. Four different types of echocardiograms are shown, including transthoracic, doppler, stress and transesphageal echocardiogram.

General anesthesia is a treatment used to block pain and put the body to sleep during surgical procedures. This video shows the different ways doctors give patients general anesthesia before a surgical procedure.

Healthcare-associated infections, or HAIs, are infections that people get in healthcare facilities, such as hospitals. This video shows risk factors, causes, types, and prevention of HAIs.

This video shows the health problems that result from smoking due to nicotine and other cancer-causing chemicals in tobacco.

This 3D medical animation depicts the anatomy of the heart. The chambers of the heart are shown, including the right atrium, left atrium, right ventricle and left ventricle. The valves are also shown, including the tricuspid, bicuspid (mitral), aortic and pulmonary valves. Blood flow through both sides of the heart and great vessels is portrayed. Blood supply to the heart through the coronary arteries is depicted.

This 3D medical animation delves into the cause and effect of heart failure in a generalized overview. It goes further to delineate between the effects of left sided heart failure and right sided heart failure. This animation then continues to discuss treatments for heart failure as well as preventative measures to keep the heart healthy.

This 3D medical animation depicts the factors that determine blood pressure. It also shows the walls of arteries and how high blood pressure affects them. Treatments for high blood pressure are presented, including key lifestyle changes and medications.

This 3D medical animation explains hyperlipidemia, commonly known as “high cholesterol.” The animation includes common diet and lifestyle treatments as well as cholesterol-lowering medications.

This 3D medical animation describes the basic anatomy and blood flow through a normal heart. It then explains the various birth defects that characterize left hypoplastic heart syndrome, and gives common treatment options and procedures.

An implantable cardiac device, or ICD, can be implanted to restore the heart's normal rhythm and prevent sudden cardiac death.

Dr. Randy Martin, an Atlanta cardiologist (heart doctor) explains mitral valve anatomy and repair in this unique medical animation + video from Nucleus and ShareWIK Media.

A non-cardiac percutaneous transluminal angioplasty, or NCPTA, is done to restore blood flow in an artery blocked by atherosclerotic plaque.

This video shows how doctors implant a pacemaker, a device that fixes certain types of arrhythmias, or abnormal heartbeats. A pacemaker restores a normal heartbeat by delivering low-energy electrical shocks through a wire in the heart.

Deep vein thrombosis (DVT or deep venous thrombosis) is when blood elements accumulate on the venous valves, creating a stationary blood clot, or thrombus, blocking the blood flow in the vein. When the thrombus breaks free of the valve leaflet, it is then called an embolus, which then lodges in the lung tissue to form a potentially life-threatening pulmonary embolism.

This 3D medical animation shows the normal anatomy and function of the heart’s mitral valve. Two main problems with the valve, called stenosis and regurgitation, are depicted. The robotic surgical system is shown, along with a brief depiction of how a surgeon uses this system to replace a damaged mitral valve.

Insulin is a hormone the body makes to maintain a proper blood sugar level. Type 1 diabetes is a condition in which the blood sugar level is too high because the body does not make insulin.
