Our Services
We provide comprehensive evaluation and management of structural heart disease using advanced, minimally invasive, catheter-based therapies. All patients are evaluated in the context of a multidisciplinary heart team approach, integrating imaging, clinical risk assessment, and guideline-directed decision-making to deliver individualized care.
Transcatheter Aortic Valve Therapies

Ventricular Septal Defect (VSD) Closure
Congenital or post-myocardial infarction (selected cases)
Minimally invasive closure in patients who are not optimal surgical candidates
Paravalvular Leak (PVL) Closure
Mitral, aortic, tricuspid
Treatment of leaks around prior prosthetic valves
Reduces heart failure symptoms and hemolysis
Tricuspid Valve Interventions
Transcatheter Tricuspid Edge-to-Edge Repair (T-TEER)
TriClip, PASCAL
Transcatheter Tricuspid Valve Replacement (TTVR)
Emerging technology
Left Atrial Appendage & Stroke Prevention
Left Atrial Appendage Occlusion (LAAO)
Watchman FLX
Stroke risk reduction in patients with atrial fibrillation who are not ideal candidates for long-term anticoagulation
Alternative to chronic oral anticoagulation in appropriately selected patients
Our Approach
- Multidisciplinary heart team model including interventional cardiology, cardiac imaging, and cardiothoracic surgery
- Care delivered in collaboration with accredited regional structural heart centers
- Emphasis on minimally invasive therapies, patient selection, and long-term outcomes
- Continuity of care from initial evaluation through post-procedural follow-up and longitudinal management
Frequently Asked Questions
What is TAVR and who qualifies for it?
Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure used to treat severe aortic stenosis. According to ACC/AHA guidelines, TAVR is appropriate for patients with symptomatic severe aortic stenosis across a range of surgical risk profiles. Patient selection is individualized based on age, anatomy, comorbidities, and heart team evaluation.
What is MitraClip (TEER) and when is it used?
Transcatheter edge-to-edge repair (TEER), commonly performed with devices such as MitraClip or PASCAL, is used to treat mitral regurgitation in patients who are not optimal candidates for surgery. It is guideline-supported for both primary and secondary mitral regurgitation in appropriately selected patients and can improve symptoms and reduce heart failure hospitalizations.
What is a Watchman device?
The Watchman device is used for left atrial appendage occlusion (LAAO). This procedure reduces stroke risk in patients with atrial fibrillation who are not ideal candidates for long-term anticoagulation. ACC/AHA guidelines support LAAO in carefully selected patients after shared decision-making.
What is a valve-in-valve procedure?
A valve-in-valve procedure is a minimally invasive treatment for patients with a failing surgical bioprosthetic valve. A new transcatheter valve is implanted within the existing valve, avoiding the need for repeat open-heart surgery in many cases.
What is PFO closure and who should consider it?
Patent foramen ovale (PFO) closure is a catheter-based procedure used to reduce the risk of recurrent stroke in select patients with cryptogenic stroke. It is recommended after careful evaluation and exclusion of other stroke causes, typically in collaboration with neurology.
What is tricuspid valve repair without surgery?
Transcatheter tricuspid valve repair (T-TEER) is a minimally invasive option for treating severe tricuspid regurgitation in patients at high surgical risk. Emerging therapies have shown improvement in symptoms and quality of life in appropriately selected patients.
Are structural heart procedures safer than surgery?
For many patients, transcatheter therapies offer a less invasive alternative to surgery with shorter recovery times. However, the best treatment depends on individual factors such as age, anatomy, and overall health. ACC/AHA guidelines emphasize shared decision-making through a multidisciplinary heart team.
How are patients evaluated for structural heart procedures?
Evaluation typically includes advanced imaging such as echocardiography and cardiac CT, along with clinical assessment and sometimes invasive hemodynamics. Cases are often reviewed by a heart team to determine the most appropriate treatment strategy.
