加州大学旧金山分校使用几种不同类型的vad. The most common type, known as an LVAD, supports the left ventricle of the heart. Other devices support the right ventricle (RVADs) or both chambers (biventricular assist devices, 或BiVADS). 我们的团队将根据您的具体情况确定最佳方案.
VAD可用于支持心脏:
- 手术期间或手术后，直到你的心脏恢复.
- 在你等待心脏移植的时候.
- If you're not eligible for a 心脏移植手术 because of age or other medical conditions.
所有vad都由几个部分组成. A small tube is connected to the heart and carries blood to the pump, which may be worn outside the body or implanted in the abdomen or chest. Another tube carries blood from the pump back to your aorta, the main artery in the body. There's also a control system and a battery pack, which are worn outside the body. The VAD's external parts are connected to the internal parts via a tube through the side of your abdomen.
Until recently VADs were too big to fit into many people's chests, especially women and children. 但由于新的更小, 更可靠的设备, vad现在是大多数需要它们的人的选择.
评价
Our 团队 will evaluate your case to determine if you might benefit from a VAD.
During the evaluation we will discuss the various types of VADs available and which may be the best choice for you. We'll also answer any questions you have about the device and implantation procedure.
如果出现以下情况，十大赌博平台排行榜可能会建议使用VAD:
- 你在等心脏移植手术. The VAD will be implanted temporarily and you can return home while you wait for a donor heart to become available. 当你接受了新心脏，VAD就会被移除. 这种暂时使用VAD的方法被称为“桥接疗法”."
- 你不适合做心脏移植手术. A VAD can be a long-term solution to help your heart work better when medication isn't helping but you're not eligible for a transplant. In this case, the VAD will be permanently implanted, a treatment known as "destination therapy.“它可以显著提高你的生活质量.
- 你的心脏功能可以恢复正常. 如果你正在从心脏手术中恢复, a heart attack or other illness that has temporarily weakened your heart, a VAD can allow your heart to rest until it's healthy enough to pump blood on its own. In this case, you may only need the VAD for a few weeks or months. 一旦你好了，它就会被移除.
vad确实存在风险, 包括任何大手术的风险, 还有中风的风险, 切口或心脏出血或感染. There's also an ongoing risk of infection at the wound site where tubing connects the internal pump to the external power source.
过程
在获得VAD之前, you will undergo tests to assess your heart function and ensure you're healthy enough to undergo surgery. 这些检查可能包括:胸部x光检查, 超声心动图, 心电图, 血液检查或心导管检查.
Implanting the VAD requires open-heart surgery under general anesthesia. 你在手术过程中会睡着，不会有任何感觉. 手术大约需要4到6个小时. Afterward, you will be transferred to the intensive care unit for recovery. 你将戴上呼吸机, 或者呼吸机, 直到你醒过来，能自己呼吸.
During your hospital stay we will teach you and your designated caregiver about the device, including how to maintain and protect it and what to do in case of emergency. By the time you leave the hospital, you and your caregiver will be experts on your VAD.
We will communicate with your primary care doctor and your local emergency services — such as the ambulance service or fire department — to alert them that you have a VAD and to explain what this means for your care.
复苏
Once you're home you'll need to do a daily check to make sure the device is working properly. This takes just a few seconds and all you need do is press a button that cues the device to run a self-test. Your caregiver will also need to change the dressing covering the site where the device exits your body. 这需要15到30分钟. Depending on the type of VAD used, you may need to take a blood thinner medication.
你不能游泳，也不能洗澡, but once the exit site has healed you'll be able to take showers using a special covering that protects the device from getting wet. It's possible to damage your VAD by touching certain electronic equipment, so your health care 团队 will instruct you about handling electronic equipment before you're discharged from the hospital.
When you're discharged, we will give you contact information for the 机械循环支持方案 团队. 如果你的VAD有任何问题, 您将能够一天24小时联系您的支持人员, 一周七天.
