The clinical effectiveness of heart transplant is substantially better than simple drug control heart failure.But there is a serious shortage of while facing row to heart donor
The problem of different reaction, infection and other secondary diseases, and the development of left ventricular assist device, it is increasingly becoming the weight for solving serious heart failure
Want approach.
Left ventricular assist device mainly has long-term auxiliary and short-term two kinds of auxiliary, develops main experienced three stages, and first
Generation is bionical beating pump, by pneumatically or electrically driving diaphragm blood pump, generates pulsation blood flow, is commonly used for transition before transplanting and controls
It treats, but the disadvantages of its volume is big, noise is big, appeal is high, blood pump inner membrance is tearable, valve is easy to aging, influences minimal invasive treatment's matter
Amount, it sometimes appear that fatal complication.Second generation left ventricular assist device volume is smaller, and infection rate is lower, and noise is bright
It is aobvious to reduce, quality of life can be obviously improved.Third generation left ventricular assist device further reduces the volume of artificial blood pump, adopts
With magnetic levitation technology, there are preferable hemodynamic characteristics, bleeding and thrombus complication can be reduced.Left ventricle assist fills at present
It sets, Heartware, the Maquet etc. assisted in short term such as assisted for a long time, it is constant current that international occupation rate is larger at home
Pump, and pulsation type heart pump can apish heart, have the systole phase and diastole similar to heart, there are positive phases and negative
The pressure phase improves the perfusion of the organs such as brain, heart and tail vein, promotes human metabolism.
Long-term left ventricular assist device needs are implanted into the patient, and are assisted human heart, and operation is complicated, and cost compared with
It is high.For short-term left ventricular assist device, what use was most wide at present is ECMO (extracorporeal membrane oxygenation system), mostly in the ward ICU
It uses, machinery equipment is very big, performs the operation more complex, costly, 2,000,000-300 ten thousand, patient's single makes general machine expense
70,000 or so are just needed with the expense of consumptive material.Equipment price is high, and operating difficulty Risks are to restrict left ventricular assist device application to push away greatly
A wide major reason.In fact, postoperative 6 months survival rates reach 87% for long-term ventricular assist device, survive within 1 year
Rate reaches 85%, and 2 years survival rates reach 79%, and survival rate reaches 73% within 3 years.And for some acute onset patients, the short-term heart
Room auxiliary device is the unique sharp weapon for saving patient.
