结构性心脏病 is a branch of interventional cardiology offering cutting edge catheter-based and minimally invasive treatment options for diseases and conditions in the non-coronary structures of the heart, 比如内墙, 阀门, 动脉, 和静脉.
我们的服务包括:
- 先进的程序和治疗 心导管实验室 by board-certified interventional cardiologists with specialized training in structural heart disease, 与心脏外科医生合作.
- An emphasis on effective communication and decision making with you about complex structural heart treatments. Multiple team members participate in decision making with you using a shared decision making approach.
- Leading edge clinical research and trials of new structural heart devices and procedures, 包括TAVR PARTNER3试验, and a study on shared decision making in the treatment of aortic stenosis.
Much of structural heart disease focuses on those of you with valvular disease who are not ideal candidates for open-heart surgery. We participate in the interdisciplinary 心脏瓣膜病 program with cardiac surgeons, 心脏成像系统, and other specialists to review and recommend the best treatment approach.
治疗方案
TAVR/TAVI (Transcatheter Aortic Valve Replacement/Implantation)
Our center is one of the few in the country currently able to offer TAVR for patients of all risk levels—and the first in northern New England to offer TAVR with low-risk aortic valve stenosis through the PARTNER3 clinical trial.
Referred to as either transcatheter aortic valve replacement (TAVR) or transcatheter aortic valve implantation (TAVI), this minimally invasive procedure repairs the aortic valve without removing the old, 损坏的阀. 类似于在动脉中放置支架的方式, TAVR delivers a replacement valve to the aortic valve site through a catheter. The new valve is expanded and pushes the old valve leaflets out of the way to take over the job of regulating blood flow.
TAVR PARTNER3 trial for low-risk, severe aortic valve stenosis
Our center has participated in the PARTNER trial since its inception, which is studying the safety and effectiveness of placing a new valve device through a catheter rather than open surgery. We are one of just 50 centers currently offering enrollment in the PARTNER3 trial for those with severe aortic stenosis at low operative risk.
TMVR(经导管二尖瓣修复)与MitraClip®
We are one of the few centers in New England offering transcatheter mitral valve repair with MitraClip® to treat mitral valve disorders.
The minimally invasive TMVR procedure uses a catheter to guide the MitraClip device through a vein in the leg to reach the heart when you have a defective or leaky mitral valve and are not a candidate for open surgery. The MitraClip device clips together a small area of the mitral valve, which continues to open and close on either side of the clip. The device allows blood flow on both sides of the clip but reduces the back flow of blood in the wrong direction.
左心房附件(LAA)关闭WATCHMAN
The WATCHMAN procedure is an alternative to blood thinners for those of you with AFib (atrial fibrillation or irregular heartbeat) who are at high risk of stroke.
AFib can cause blood to clot in a small pouch of the heart called the left atrial appendage (LAA). Blood clots can break loose from the LAA and travel to the brain, 导致中风, 或者身体的其他部位. The WATCHMAN procedure utilizes a catheter to place a small umbrella-like device to block off the LAA and keep harmful blood clots from escaping.
复杂的结构性心脏病治疗
Additional complex procedures available through the 结构性心脏病 Program include:
- 瓣旁泄漏闭合, to address prosthetic 阀门 that are leaking following surgical or transcatheter placement.
- Percutaneous balloon valvuloplasty of the mitral valve for rheumatic mitral stenosis.
- Options for transcatheter valve replacement in the native mitral valve if you are at very high risk for surgery and have the appropriate anatomy. 除了, transcatheter valve-in-valve procedures are being performed in both the aortic and mitral position.
- Coronary fistulae closure to address abnormal connections from the coronary vessels to other parts of the heart, performed using a collaborative approach between adult and pediatric interventional cardiologists.
