Cardiology is a medical specialty and a branch of internal medicine concerned with disorders of the heart. It deals with the diagnosis and treatment of such conditions as congenital heart defects, coronary artery disease, electrophysiology, heart failure and valvular heart disease. Subspecialties of the cardiology field include cardiac electrophysiology, echocardiography, interventional cardiology and nuclear cardiology.
Coronary angiography involves the study of coronary arteries which supply the heart. It is done by injecting a dye into a peripheral artery.
Closure devices are used to close a defect or an opening between the right and left sides of the heart. Some of these birth defects are located in the wall (septum) between the upper chambers (atria) of the heart:
Patent Foramen Ovale (PFO)
Atrial Septal Defect (ASD)
A valvuloplasty, also known as balloon valvuloplasty or balloon valvotomy, is a procedure to repair a heart valve that has a narrowed opening. In this valve condition, the valve flaps (leaflets) may become thick or stiff, and they may fuse together (stenosis).
A pacemaker insertion is the implantation of a small electronic device that is usually placed in the chest (just below the collarbone) to help regulate slow electrical problems with the heart. A pacemaker may be recommended to ensure that the heartbeat does not slow to a dangerously low rate.
A coronary care unit (CCU) or cardiac intensive care unit (CICU) is a hospital ward specialized in the care of patients with heart attacks, unstable angina, cardiac dysrhythmia and (in practice) various other cardiac conditions that require continuous monitoring and treatment.
Coronary angiography is a procedure that uses a special dye (contrast material) and x-rays to see how blood flows through the arteries in your heart.
