Background technology
Heart failure has become the healthy heavy burden in the whole world, and at present whole world heart failure patient there are about 26,000,000, and illness rate is
1-2%.More than 70 years old crowd's heart failure illness rate >=10% of American-European countries.In the 74% heart failure patient course of disease at least one
Easily there is the deterioration of disease in complication, such patient, cause admission rate again and the death rate high.Advanced heart failure prognosis
More worse than part entity tumour and myocardial infarction, 5 annual survival rates of severe patient are less than 20%.Heart failure brings for society simultaneously
Huge financial burden.
In recent years, paid attention to by clinic more and more, it main reason is that it becomes whole world morbidity and dead head
Want one of inducement, even and if calcification score technology development it is widely available instantly, still have 20%～50% myocardial infarction patient
Can switch to heart failure patient, and left ventricle geometry is used as one of the main prognosis of heart failure, particularly myocardial ischemia
Heart geometry can be changed.Especially it is easiest to myocardial infarction occur in three coronary arteries with descending anterior branch, as a result caused antetheca
, there is apex impaired movement even aneurysm in large area infarct, further increases remodeling ventricle and CHF occurs
Symptom.Myocardial necrosis and subsequent scarring, cause left ventricular remodeling after acute anterior wall myocardial infarction patients, cause left ventricle dilation and a left side
Ventricular systolic function declines.The important symbol of remodeling ventricle is exactly wall tension change and heart volume change.Therefore it is mechanical
The reduction bulk of left ventricle of property can mitigate wall tension so as to improve remodeling ventricle, here it is the theory of surgery partial left ventriculectomy according to
According to.Although the history in partial left ventriculectomy existing more than 50 years, surgery operating wound is larger, and the requirement to surgery patient compared with
Height is limited clinical practice.
