Angina

Angina is chest pain or discomfort that occurs when your heart doesn’t get as much blood and oxygen as it needs. Over time, the coronary arteries that supply blood to your heart can become clogged with plaque. If one or more arteries are partly clogged, not enough blood can flow through, and you can feel […]

Angiogram

A Coronary Angiogram is a special X-ray test performed to find out if your coronary arteries are clogged, where and by how much. During an angiogram, your doctor inserts a thin tube (catheter) into an artery and up to the heart. Once in place, a dye that is visible by X-rays (contrast dye) is injected […]

Angioplasty

Angioplasty (also called percutaneous coronary intervention or PCI) opens blocked arteries and restores normal blood flow to your heart muscle. It is done through a small puncture in a leg or arm artery and opens a clogged heart artery by inflating a tiny balloon in it. It is often combined with implantation of a stent […]

Arrhythmias

An Arrhythmia is an abnormal rhythm of the heart and is caused by problems with your heart’s electrical system. The electrical impulses may happen too fast, too slowly, or erratically – causing the heart to beat too fast, too slowly, or erratically. There are two basic kinds of arrhythmias. Bradycardia is when the heart rate […]

Atrial Fibrillation

Atrial Fibrillation(also called AFib or AF) is a quivering or irregular heartbeat (arrhythmia) that can lead to stroke and other heart-related complications. In atrial fibrillation, the upper chambers of the heart (the atria) beat irregularly (quiver) instead of beating effectively to move blood into the ventricles.

Cardiac Resynchronization Therapy

Some people with heart failure develop abnormal heartbeats, or arrhythmias. Some arrhythmias may reduce how well the heart’s lower chambers (ventricles) function.Cardiac Resynchronization Therapy (CRT), also known as biventricular pacing, may be needed. In this procedure, a special pacemaker is used to make the ventricles contract at the same time. This helps the lower heart […]

Cholesterol and CAD

Coronary artery disease (CAD) occurs when the inside (the lumen) of one or more coronary arteries narrows, limiting the flow of oxygen-rich blood to surrounding heart muscle tissue. Atherosclerosis is the process that causes the artery wall to get thick and stiff. It can lead to complete blockage of the artery, which can cause a heart attack. […]

Hemorrhagic Stroke

Hemorrhagic Stroke results from a weakened vessel that ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surrounding brain tissue. The two types of hemorrhagic strokes are subarachnoid hemorrhage and intracerebral hemorrhage. Subarachnoid hemorrhage (SAH) occurs when a blood vessel on the surface of the brain ruptures and bleeds into the space […]

Pacemaker

A pacemaker is a small battery-operated device that helps your heart beat in a regular rhythm. It does this with a small electric stimulation that helps your heart to beat regularly. Your doctor puts the pacemaker under the skin on your chest, just under your collarbone. It’s hooked up to your heart with tiny wires.

Valve Repair

Though valve replacement surgery is very common, your doctors will always prefer to repair your natural valve before replacing it. When the outflow valves (aortic and pulmonary) are not functioning properly, a balloon catheter can sometimes be used to restore more normal function. This is called valvuloplasty, just like angioplasty is used to open coronary […]

Valve Replacement

Heart valves damaged beyond simple repair can often be replaced. The most commonly replaced valves are the aortic and mitral valves. When either of these valves exhibit advanced stenosis, they may be candidates for replacement. Some replacement valves are implanted using a balloon catheter, much like coronary angioplasty. When the mitral valve is too loose […]

Valve Stenosis

Stenosis literally means narrowing. When heart valves are stenotic, they do not fully open and the passageway for blood flow is narrowed. And sometimes valves with stenosis do not close properly, allowing blood to flow backwards (regurgitate). Stenotic heart valves cause the heart to work harder, trying to pump blood through a smaller opening. Stenosis […]
