Cardiology is a branch of medicine dealing with disorders of the heart. The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology.
A pacemaker is a small device that’s placed in the chest or abdomen to help control abnormal heart rhythms. This device uses low-energy electrical pulses to prompt the heart to beat at a normal rate.Pacemakers are used to treat arrhythmias. Arrhythmias are problems with the rate or rhythm of the heartbeat.
Angiography or arteriography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers. This is traditionally done by injecting a radio-opaquecontrast agent into the blood vessel and imaging using X-ray based techniques such as fluoroscopy.
Angioplasty or Ballon Angioplasty
The usefulness of angioplasty depends upon the severity of arterial narrowing. Angioplasty is often recommended when arterial narrowing is moderate to severe, or when only one or two coronary arteries are severely narrowed.
The doctor threads a thin tube through a blood vessel in the arm or groin up to the involved site in the artery. The tube has a tiny balloon on the end. When the tube is in place, the doctor inflates the balloon to push the plaque outward against the wall of the artery. This widens the artery and restores blood flow.
Coronary angioplasty (AN-jee-o-plas-tee), also called percutaneous coronary intervention, is a procedure used to open clogged heart arteries. Angioplasty involves temporarily inserting and inflating a tiny balloon where your artery is clogged to help widen the artery.
Heart Valve Surgery
During heart valve surgery, one or more valves are repaired or replaced. Repair means that the valve is mended to help it work better. Replacement means your diseased valve is removed and a new valve is inserted in its place. Whether a valve will be repaired or replaced can only be decided once surgery has begun. Your surgeon will talk with you about his or her plans for surgery and any other procedures you may need.
