Transcatheter Valve Procedures
Heart valve repair & replacement surgery
We’re home to New Jersey’s largest, most experienced transcatheter valve and structural heart program. Nationally ranked since 2012, our multidisciplinary team delivers expert evaluation, advanced treatment, and innovative, patient-centered care.
The latest in transcatheter valve technologies
Our multidisciplinary heart team includes cardiologists across subspecialties, vascular specialists, cardiac surgeons, and allied health professionals experienced in both traditional and novel treatments for a wide range of valve conditions.
A minimally invasive procedure to treat a narrowed or leaking aortic valve by placing a new valve through a catheter.
Balloon aortic valvuloplasty
A procedure that uses a balloon to open a narrowed aortic valve and improve blood flow.
Balloon mitral valvuloplasty
A balloon is used to open a narrowed mitral valve and improve blood flow.
Leaflet valve modification
Specialized techniques to reshape or improve valve leaflets to enhance valve function.
Transcatheter edge-to-edge repair (TEER – Mitral)
A minimally invasive repair that helps reduce leakage of the mitral valve.
Transcatheter mitral valve replacement (TMVR)
Replacement of the mitral valve using a catheter-based approach.
Transcatheter edge-to-edge repair (TEER – Tricuspid)
A minimally invasive repair to reduce leakage of the tricuspid valve.
Transcatheter tricuspid valve replacement (TTVR)
Replacement of the tricuspid valve without open-heart surgery.
Atrial septal defect (ASD) closure
Closure of a hole between the heart’s upper chambers.
Left atrial appendage occlusion (LAAO – Watchman™, Amulet™, etc.)
Seals off a small pouch in the heart to help prevent blood clots and reduce stroke risk in atrial fibrillation.
Patent foramen ovale (PFO) closure
Closure of a small opening between the heart’s upper chambers to reduce stroke risk.
Paravalvular leak repair
Treatment of leaks that occur around a previously implanted heart valve.
Ventricular septal defect (VSD) closure
Closure of a hole between the heart’s lower chambers.
Percutaneous thrombus and mass removal
Removal of blood clots or abnormal masses from the heart or blood vessels using catheter-based techniques.
Valve conditions we treat
Our cardiac specialists provide expert care for a wide range of heart valve conditions.
Prosthetic valve dysfunction (stenosis, regurgitation)
Paravalvular leak
Research and Clinical Trials
Pioneering heart valve therapies
Our cardiac team is dedicated to advancing heart valve care through groundbreaking research. We are actively participating in multiple national and international clinical trials to develop innovative treatment options.
TAVR program highlights
Gagnon Cardiovascular Institute at Morristown Medical Center was the first hospital in New Jersey to offer transcatheter aortic valve replacement (TAVR) for severe aortic stenosis. Gagnon treats more valve patients than any other hospital in New Jersey.
- We have performed more than 6,000 transcatheter aortic valve replacement (TAVR) procedures, the first in New Jersey and among the first to accomplish this in the United States.
- We perform more than 500 transcatheter valve procedures annually, placing our program in the top 1% of all structural heart programs in the United States.
- Received American College of Cardiology (ACC) Transcatheter Valve Certification. Only 6% of 750+ hospitals performing Transcatheter Aortic Valve Replacement (TAVR) have achieved this elite recognition of best practices and quality care.
- Comprehensive structural heart multi-disciplinary team including the latest in transcatheter valve technologies.
- Committed to research and are currently enrolling in thirteen national/global studies.
- Morristown Medical Center randomized the first patient in the world to the EARLY TAVR Trial (Evaluation of Transcatheter Compared to Surveillance). The trial was for patients with asymptomatic severe aortic stenosis.
- Morristown Medical Center performed world’s first catheter-based mitral valve repair in the CLASP IID Pivotal Trial.
- Our co-director was named one of the world’s most highly cited researchers. Only one in 1,000 scientists receive this designation. His papers rank in the top 1% of citations for clinical medicine for a second year.
- All of our valve and structural heart disease surgery patients recover in a dedicated, all-private, 36 bed unit.

Patient Story
"When the anesthesia wore off, I felt good enough to dance a jig. I didn’t need any pain medication. I could not believe that all I had was a small bandage, and the next day, an even smaller one. It was truly an amazing process, absolutely amazing."
Lynn M., TAVR recipient
Awards and designations
