For patients who need a mitral or aortic valve replacement, Weill Cornell Medicine’s Department of Cardiothoracic Surgery offers several surgical options, including a minimally invasive technique called percutaneous transcatheter valve replacement (TAVR or TMVR).
Weill Cornell Medicine: Pioneers in transcatheter valve replacement surgery
TAVR is a minimally invasive approach in which a surgeon threads a catheter (thin tube) up to the heart through a blood vessel in the groin to replace the damage valve. This technique makes valve replacement possible for patients who would not tolerate conventional heart surgery.
Weill Cornell Medicine and NewYork-Presbyterian are leaders in the development this surgical technique—both for mitral and aortic valve replacement. In fact, our physicians participated as investigators in two pivotal clinical trials that established the effectiveness of percutaneous (transcatheter) valve surgery:
• The PARTNER Trial, which in 2011 demonstrated that transcatheter aortic valve implantation (TAVI) was as effective as conventional open-heart surgery for reducing mortality among high-risk patients with aortic stenosis. In 2010, PARTNER Trial investigators reported that patients who were not candidates for surgery fared much better with TAVI than patients who were treated medically. Currently, our team is conducting a new trial assessing the safety and efficacy of the SAPIEN 3 transcatheter heart valve in low-risk patients.
• The EVEREST II trial evaluated the percutaneous implantation of a clip that grasps and approximates the edges of the mitral valve leaflets. The percutaneous approach was associated with superior safety and similar improvements in clinical outcomes compared with conventional surgery.
Our physicians continue to play a leading role in the clinical trials assessing the latest percutaneous mitral and aortic valve replacement approaches, giving us more experience than most centers in these emerging new techniques.
Our TAVR patients also benefit from:
• Our superior record of excellent surgical outcomes
• Our surgeons works with each patient to develop an individualized, comprehensive treatment plan
• Collaboration with other specialists (such as cardiologists and anesthesiologists) to provide seamless, high-quality care
