Features of modern cardiac surgery
Cardiac and Cardiovascular Surgery - Surgery is the section dealing with the treatment of cardiovascular diseases using surgical methods. Today, cardiac surgery is the most effective way to treat certain types of heart defects and heart disease.
Cardiac surgery is a relatively young but rapidly developing science. If before heart surgery carried out only when you switch on the AIC circulation (heart-lung machine that replaces the heart during the operation), but today there are techniques that allow to carry out operations on a beating heart, without going to cardiopulmonary bypass. Finally, today, the methods and available equipment for endoscopic heart surgery when the skin of the chest made a small incision, allowing you to enter a special device by which heart surgery is performed, and the surgeon watches it and is controlled by the monitor and control panel .
In some cases, a heart surgery
Heart surgery is usually required in cases where the condition of the patient to normalize without operation becomes impossible, that is conducted conservative treatments and do not help the patient's condition deteriorates. Only surgical treatment require some heart defects, the defect structure of his blood circulation so that the patient can lead a normal life.
In recent years, increasingly with the help of heart surgery treat coronary heart disease, thus preventing severe complications, such as myocardial infarction, as well as surgically removing the effects of myocardial infarction
Myocardial infarction - the most formidable diagnosis
(eg, thinning and bulging of scarring occurring after myocardial infarction).
How to operate with coronary heart disease
The main cause of coronary heart disease (CHD) is atherosclerosis
Atherosclerosis - a chronic disease of the arteries
In which the walls of blood vessels are formed plaques gradually bridging vessel lumen. For the heart is very dangerous because the heart muscle (myocardium) can not function without a proper blood supply, blood delivers her nutrients and oxygen. If a blood vessel that carries blood to the myocardium (coronary artery disease), is sealed, then immediately comes necrosis (infarction) of the myocardium. The area of dead tissue is greater than most coronary artery ceased to function.
In order to prevent a myocardial infarction is made bypass surgery (CABG), when blood flow to the heart muscle is restored by bypassing constriction of a coronary vessel via shunt segments veins or arteries taken from the patient (for example in the extremities). Today CABG is done both with disconnection of the heart (instead of the heart works AIC), and without turning off, creating the stillness of the heart only in the treated area.
In addition to CABG currently undergoing balloon angioplasty surgery: using special equipment crushed atherosclerotic plaque in the artery, and then injected into the artery stent - a special device that prevents arteries subsides. Heart surgery in ischemic heart disease as required in the case where after a myocardial infarction in the heart muscle to thinning formed protrusion (aneurysm).
Operations at the heart defects
Heart defects can be congenital or acquired. Many of them do not require surgery, and some even take place unnoticed by the patient. But there are heart defects (especially congenital) in which the operation is vital. Most of these heart defects occur in the first hours of life. Cardiac surgery has been some progress in the treatment of certain severe congenital heart disease, but not all.
Sometimes a congenital heart defect
Heart defects - time heals?
age passes, but if he did not pass on their own and growing signs of heart failure
Heart failure - when the heart is unable to cope with the work
, The operation is shown. In many congenital heart diseases, there are waste and-proven methods of surgical treatment.
Acquired heart defects operate only when conservative treatment is ineffective, and the signs of the disease is increasing. In acquired heart diseases often suffer from heart valves that prevent blood flow in the reverse direction. In violation of the structure of these valves, the blood while reducing the attack is not only the right, but in the opposite direction, which can severely disrupt the blood circulation in general. In such cases, surgery is performed to replace the heart valve in the valve from animal tissue (it has a limited time operation) or a special device, replacing a heart valve.
Operation Heart Transplant
In some cases, the patient's life-saving resort to at least - a heart transplant. In our time, after such an operation, more than half of patients live more than five years. This is a good opportunity, given that cardiac surgery is developing very rapidly and it is possible within five years to such patients can help more than dramatically.
