背景技术Background technique
心脏是人体最重要的器官,心脏分为左右两部分,每一部分又包括心房和心室。左右心房和左右心室分别由房间隔和室间隔分开。在心脏内存在四个心脏瓣膜,即三尖瓣、肺动脉瓣、二尖瓣和主动脉瓣。在人体血液循环机构中,四个心脏瓣膜起着至关重要的作用。体循环机构的缺氧血液经腔静脉进入右心房,然后通过三尖瓣进入右心室,右心室收缩将血液通过肺动脉瓣压入肺循环机构,经过肺氧饱和后的血液经肺静脉回到左心房,再经二尖瓣到达左心室,左心室收缩将血液通过主动脉瓣排入主动脉而重返体循环机构。主动脉瓣膜下有左右冠状动脉开口。四个心脏瓣膜的结构保证了血液顺方向时瓣膜开放,逆方向时关闭,防止了血液返流而引起的心脏负担加重。但是,由于各种原因,可以导致心脏瓣膜的后天性损伤或病变,如风湿,动脉粥样硬化等。此外,先天性心脏病如法乐氏四联症,术后远期也可产生肺动脉瓣膜病变。瓣膜病变后表现为瓣膜功能逐渐丧失,如瓣膜关闭不全导致血液返流,瓣膜狭窄导致血液流通不畅,或关闭不全和狭窄二者兼并,以至加重心脏负担,导致心脏功能衰竭。对于心脏瓣膜的后天性损伤或病变,传统的治疗方法是开胸,心脏停跳后,在低温体外循环支持下,打开心脏进行病变瓣膜的外科修复或用人工心脏瓣膜置换。现有的人工心脏瓣膜分两大类:金属机械瓣膜和生物瓣膜。生物瓣膜由牛心包、牛颈静脉瓣、猪主动脉瓣等动物材料处理后制成。上述开心手术的方法,手术时间长,费用高,创伤大,风险大,金属机械瓣膜置换后病人需要长期抗凝治疗,生物瓣膜的材料寿命有限,通常需要再手术。The heart is the most important organ of the human body. The heart is divided into two parts, the left and the right, and each part includes the atrium and the ventricle. The left and right atria and right and left ventricles are separated by the atrial and ventricular septum, respectively. There are four heart valves in the heart, namely the tricuspid valve, pulmonary valve, mitral valve and aortic valve. In the human blood circulation mechanism, the four heart valves play a vital role. The hypoxic blood from the systemic circulation mechanism enters the right atrium through the vena cava, and then enters the right ventricle through the tricuspid valve. The contraction of the right ventricle pushes the blood into the pulmonary circulation mechanism through the pulmonary valve, and the oxygen-saturated blood returns to the left atrium through the pulmonary vein, and then Through the mitral valve to the left ventricle, the left ventricle contracts to expel blood through the aortic valve into the aorta and return to the systemic circulation. There are left and right coronary artery openings under the aortic valve. The structure of the four heart valves ensures that the valves open when the blood flows in the forward direction and close when the blood flows in the opposite direction, preventing the heart from increasing the burden caused by the backflow of blood. However, due to various reasons, acquired damage or disease of heart valves can be caused, such as rheumatism, atherosclerosis, etc. In addition, congenital heart disease such as tetralogy of Fallot can also cause pulmonary valve disease in the long term after surgery. After valvular disease, the valve function is gradually lost, such as valvular insufficiency leading to blood regurgitation, valvular stenosis leading to poor blood flow, or both insufficiency and stenosis, which will increase the burden on the heart and lead to heart failure. For the acquired damage or disease of the heart valve, the traditional treatment method is to open the chest, and after the heart stops beating, the heart is opened to perform surgical repair of the diseased valve or replace it with an artificial heart valve under the support of hypothermic extracorporeal circulation. The existing artificial heart valves are divided into two categories: metal mechanical valves and biological valves. Biological valves are made from processed animal materials such as bovine pericardium, bovine jugular valve, and porcine aortic valve. The above-mentioned open-heart surgery method has long operation time, high cost, large trauma, and high risk. After metal mechanical valve replacement, the patient needs long-term anticoagulant treatment, and the material life of the biological valve is limited, and reoperation is usually required.
为了解决上述开心手术治疗心脏瓣膜存在的问题,现在已有人尝试不作开心手术,而采用经皮介入方法输放人工心脏瓣膜。现有技术的介入式人工心脏瓣膜有二种:In order to solve the above-mentioned problems of open-heart surgery for the treatment of heart valves, some people try not to perform open-heart surgery, but use percutaneous intervention to deliver artificial heart valves. The interventional artificial heart valve of prior art has two kinds:
1、球囊扩张型1. Balloon-expandable
这种球囊扩张型人工心脏瓣膜为生物瓣膜,其介入方法是在一个可塑性变形的支架上分别固定生物瓣膜,通过径向压缩在一个球囊上后直径变小,经皮输放,然后给球囊加压使支架扩张固定,达到工作状态。This balloon-expandable artificial heart valve is a biological valve. The intervention method is to respectively fix the biological valve on a plastically deformable stent, radially compress it on a balloon, and then reduce the diameter, deliver it percutaneously, and then give it to the patient. The balloon is pressurized to expand and fix the stent to reach the working state.
1989年Henning Rud ANDERSEN(专利号WO9117720)率先进行了猪主动脉瓣经导管人工心脏瓣膜置换(文献…European Heart Journal 1992 13,704-708)。In 1989, Henning Rud ANDERSEN (Patent No. WO9117720) took the lead in carrying out porcine aortic valve transcatheter artificial heart valve replacement (document... European Heart Journal 1992 13, 704-708).
2000年Philippe BONHOEFFER(专利号EP1057460)和Alain CRIBIER(专利号EP0967939)分别首次进行了在人体的经导管介入的肺动脉瓣膜和主动脉瓣膜的人工心脏瓣膜置换。In 2000, Philippe BONHOEFFER (Patent No. EP1057460) and Alain CRIBIER (Patent No. EP0967939) carried out the artificial heart valve replacement of the pulmonary valve and aortic valve in the human body for the first time respectively.
球囊扩张型人工瓣膜存在的缺点和问题是:其直径由球囊直径所决定,如果人工瓣膜的直径一开始没选择好,或某些生理变化后,如自然生长、病理性血管扩张等,自然瓣膜的口径大小可能增大,而人工瓣膜的口径不能适应性增大,人工瓣膜有松动或滑脱的危险,只能进行二次球囊再扩张。The disadvantages and problems of the balloon-expandable artificial valve are: its diameter is determined by the diameter of the balloon. If the diameter of the artificial valve is not selected at the beginning, or after some physiological changes, such as natural growth, pathological vascular expansion, etc., The caliber of the natural valve may increase, but the caliber of the artificial valve cannot be adaptively increased, and the artificial valve may loosen or slip off, so only secondary balloon re-expansion can be performed.
2、自扩张型2. Self-expanding
这种人工瓣膜设有一个弹性变形支架,径向压缩后可自行扩张。This prosthetic valve features an elastically deformable stent that expands on its own after being radially compressed.
Marc BESSLER(专利号US5855601)和Jacques SEGUIN(专利号FR2826863,FR2828091)也设计了经导管人工心脏瓣膜置换。不同的是他们用了一个可弹性变形支架,径向压缩后可自行扩张。Marc BESSLER (Patent No. US5855601) and Jacques SEGUIN (Patent No. FR2826863, FR2828091) also designed transcatheter prosthetic heart valve replacement. The difference is that they used an elastically deformable stent that can expand by itself after radial compression.
Philippe BONHOEFFER(专利号EP1281375,US2003036791)的人工心脏瓣膜利用一个可弹性变形支架,在支架上游端或远端装有触头,压在内外两个鞘管内。The artificial heart valve of Philippe BONHOEFFER (patent No. EP1281375, US2003036791) utilizes an elastically deformable stent, and contacts are housed at the upstream end or the distal end of the stent, and are pressed in the two inner and outer sheath tubes.
本申请人曾在中国发明专利申请号200410054347.0中提到使用了中段为鼓型的支架瓣膜和自扩型加强化合成支架瓣膜,及捆绑式输放装置。The applicant once mentioned in the Chinese invention patent application number 200410054347.0 that he used a drum-shaped stent valve in the middle section, a self-expanding reinforced synthetic stent valve, and a bundled delivery device.
自扩张型人工瓣膜存在的缺点和问题是:自扩张型人工心脏瓣膜与鞘管间摩擦力大,影响人工瓣膜准确释放。The disadvantages and problems of the self-expandable artificial heart valve are: the frictional force between the self-expandable artificial heart valve and the sheath tube is large, which affects the accurate release of the artificial valve.
该捆绑式输放装置的支架拉线,穿过人工瓣膜的可变形单元时摩擦力大,不穿过时拉线易脱位。The bracket stay wire of the bundled delivery device has a large friction force when passing through the deformable unit of the artificial valve, and the stay wire is easy to dislocate when not passing through.
上述球囊扩张型和自扩张型人工心脏瓣膜存在的共同缺点和问题是:The common shortcoming and the problem that above-mentioned balloon expansion type and self-expanding artificial heart valve exist are:
1、现有的介入式人工支架瓣膜的输放装置和径向压缩下的支架瓣膜较硬,弯曲性差,经过主动脉弓不容易,不能对准自然主动脉瓣膜口。1. The delivery device of the existing interventional artificial stent valve and the stent valve under radial compression are relatively hard and poor in flexibility. It is not easy to pass through the aortic arch and cannot be aligned with the natural aortic valve orifice.
2、即便在x光透视帮助下,介入式人工支架瓣膜和它的输放装置的轴向上下游定位也因对解剖位置的判断不准和血流冲击下的人工瓣膜不稳定而变得不容易。介入式人工主动脉瓣膜如果位置偏上游可影响二尖瓣,如果位置偏下游可堵阻冠状动脉开口。2. Even with the help of X-ray fluoroscopy, the axial upstream and downstream positioning of the interventional artificial stent valve and its delivery device becomes uncertain due to the inaccurate judgment of the anatomical position and the instability of the artificial valve under the impact of blood flow. easy. The interventional prosthetic aortic valve can affect the mitral valve if it is positioned upstream, and it can block the coronary artery opening if it is positioned downstream.
3、介入式主动脉瓣人工支架瓣膜和它的输放装置的旋转方向定位没能解决。介入式人工主动脉瓣膜如果旋转位置不对可堵阻冠状动脉开口。3. The rotation direction positioning of the interventional aortic valve artificial stent valve and its delivery device cannot be solved. The interventional prosthetic aortic valve can block the opening of the coronary artery if it is rotated incorrectly.
4、自扩型人工支架瓣膜高度压缩下,鞘管的回退会遇到很大的阻力。退鞘管的阻力和困难还会使操作者将已定好位的人工支架瓣膜移位。4. When the self-expanding artificial stent valve is highly compressed, the retraction of the sheath will encounter great resistance. The resistance and difficulty of withdrawing the sheath can also cause the operator to displace the fixed artificial stent valve.
5、在释放过程中,支架瓣膜逐渐半扩张到全扩张,所需时间超过一个心跳周期。扩张的支架瓣膜会阻碍血流,支架瓣膜也可因血流冲击而使其位置改变。特别是球囊扩张型人工支架瓣膜在球囊扩张过程中完全阻断血流。5. During the release process, the stent valve gradually expands from half to full expansion, and the required time exceeds one heartbeat cycle. The expanded stent valve can obstruct blood flow, and the stent valve can also change its position due to the impact of blood flow. In particular, balloon-expandable prosthetic stent-valves completely block blood flow during balloon expansion.
6、如果病人已有冠状动脉搭桥(Coronary Artery Bypass),已植入的人工支架瓣膜不应该在升主动脉处影响搭桥开口的血液灌流。6. If the patient has coronary artery bypass (Coronary Artery Bypass), the implanted artificial stent valve should not affect the blood perfusion of the bypass opening at the ascending aorta.
7、Jacques SEGUIN和Philippe BONHOEFFER的主动脉瓣自扩型支架瓣膜如能成功植入,虽然术后不会马上影响冠状动脉的灌流,但是支架中部在主动脉根部不贴血管壁,让血流从支架网眼中流过,一方面会有血栓形成的可能;另一方面会影响或妨碍未来可能的冠状动脉介入诊断和治疗。7. If the aortic valve self-expanding stent valve of Jacques SEGUIN and Philippe BONHOEFFER can be successfully implanted, although the perfusion of the coronary artery will not be affected immediately after the operation, the middle part of the stent will not stick to the vessel wall at the aortic root, so that the blood flow Flow through the stent mesh, on the one hand, may cause thrombus formation; on the other hand, it will affect or hinder possible future diagnosis and treatment of coronary artery intervention.
8、释放扩张后的支架瓣膜的固定也存在以下问题:8. There are also the following problems in the fixation of the stent valve after release and expansion:
a)收缩期和舒张期血流冲击会使固定不好的人工支架瓣膜移动。a) The impact of blood flow during systole and diastole will move the poorly fixed artificial stent valve.
b)有些主动脉瓣关闭不全的病人其主动脉根部术前已有病理性扩张,需要很大的支架瓣膜才能与其吻合固定。b) Some patients with aortic valve insufficiency have pathological expansion of the aortic root before surgery, and a large stent valve is needed to anastomose and fix it.
c)有些病人在人工支架瓣膜植入后局部会有解剖性变化,如扩张,使不能相应变化的支架瓣膜失去有效固定。c) Some patients will have local anatomical changes after the artificial stent valve is implanted, such as expansion, so that the stent valve that cannot be changed accordingly will lose effective fixation.
9、扩张固定后的人工支架瓣膜在很多情况下有瓣周漏(Para valvularleaks),即血液从支架瓣膜和血管壁之间漏过。9. The artificial stent valve after expansion and fixation has paravalvular leaks (Para valvular leaks) in many cases, that is, blood leaks between the stent valve and the vessel wall.
11、如果为了固定好而采用大直径支架瓣膜,瓣叶联合点(Commi ssure)会承受很大应力,造成瓣膜叶联合点撕损。11. If a large-diameter stent valve is used for fixation, the commissure of the leaflets will bear a lot of stress, resulting in tearing of the commissure of the valve leaflets.
