二尖瓣经导管边缘到边缘修复术(TEER)

评价

To assess the condition of your mitral valve and determine whether you are a candidate for TEER, your doctor may request one or more of the following diagnostic tests:

• 冠状动脉造影. A catheter is threaded through a blood vessel in your wrist or groin to an artery in your heart, and a harmless dye that shows up well on X-rays is injected into the catheter. The test provides detailed images that reveal how well the coronary arteries are functioning. The cardiac catheterization for this test also allows doctors to measure the pressure inside the heart chambers.
• 超声心动图. This test uses sound waves to produce detailed images of your heart, allowing doctors to assess the structure of chambers and valves and to observe blood flow. 经胸超声心动图, the images are captured by placing an ultrasound transducer (the device emitting sound waves) in various spots on the chest and abdomen. 经食管超声心动图, 一根细管将换能器送入食道, enabling doctors to obtain clearer heart images from inside the body.
• 血管超声. This imaging test uses sound waves to let doctors see how blood moves through veins and arteries.
• 血液测试. Analyzing a blood sample helps doctors assess a variety of health-related factors. Tests may quantify red blood cells and levels of electrolytes (elements such as sodium and potassium). 血液测试 can also indicate how well the kidneys, liver and thyroid are functioning. In some instances, 血液测试 can point to the cause of a heart problem.

当你的评估完成时, our team of specialists – which includes general cardiologists, 介入心脏病学家, heart surgeons and imaging specialists – meets to discuss your case and determine whether TEER is an appropriate option for you.

过程

TEER is performed in the UCSF cardiac catheterization lab rather than a standard operating room. 这个过程通常需要两到三个小时, and patients are under general anesthesia (completely asleep).

开始, the doctor makes a small incision in the groin area to access the femoral vein and – guided by X-ray and ultrasound imaging – threads a catheter through this blood vessel up to the heart. A tool on the catheter tip makes a tiny hole in the thin layer of muscle dividing the heart's chambers, so that the catheter can pass through and be guided to the mitral valve. The MitraClip or Pascal device is inserted through the catheter and brings the valve flaps closer together, facilitating better closure when the heart beats and reducing the backflow of blood. Once the device is in place and working, the doctor removes the catheter.

复苏

遵循程序, patients are monitored in either the post-anesthesia care unit or intensive care unit, 取决于需要的护理水平. 病人 are generally encouraged to be up and walking within 24 hours, and most are able to do so. You will likely spend one to two nights in the hospital. 在你术后住院期间, your care team will conduct follow-up tests to ensure the device is functioning properly. 这可能包括胸部x光检查, 血液测试, an electrocardiogram (EKG) and an echocardiogram (heart ultrasound).

回家之前, your heart team will talk with you about how to care for yourself, 提供饮食指导, 锻炼, 小心你的切口, 以及使用现有或新的药物. You will likely receive guidance about blood thinners.

出院后, you need to have regular checkups with your primary care provider and local cardiologist. 你会在需要的时候看到你的UCSF心脏团队. These checkups are important to ensuring the device is functioning properly and to detecting any potential problems early.
