Structural Heart & Interventional Cardiology

Procedures

Expert performance of the full spectrum of structural heart and complex coronary procedures — NYU Langone Health, New York. Each page covers the procedure in depth — what it is, who needs it, how it's done, and the latest evidence.

Structural Heart Procedures

Aortic Valve · Structural Heart

TAVR — Transcatheter Aortic Valve Replacement

Replacing a diseased aortic valve through a catheter without open heart surgery. The most common structural heart procedure — now preferred for most patients with severe aortic stenosis.

Left Atrial Appendage · AF

Watchman — LAA Occlusion

Sealing the left atrial appendage to prevent stroke in atrial fibrillation — an alternative to lifelong blood thinners for patients who cannot safely anticoagulate.

Tricuspid Valve · Structural Heart

Tricuspid TEER & TTVR

TriClip edge-to-edge repair and Evoque transcatheter tricuspid valve replacement for severe tricuspid regurgitation. The fastest-growing field in structural cardiology.

Mitral Valve · Structural Heart

MitraClip — Mitral Valve TEER

Repairing a leaking mitral valve with a clip — no surgery required. For both primary degenerative MR and secondary functional MR in heart failure patients.

Congenital · Structural Heart

PFO & ASD Closure

Closing holes between the heart's upper chambers to prevent cryptogenic stroke (PFO) or treat right heart volume overload (ASD). Same-day procedure for most patients.

Coronary & Interventional Procedures

Advanced Heart Care · MCS

Cardiogenic Shock & Impella

Expert management of the most critical cardiac emergency — using Impella, VA-ECMO, and advanced hemodynamic monitoring to restore circulation and save lives.

Coronary · Complex PCI

High-Risk & Complex Coronary PCI

Left main PCI, rotational atherectomy, intravascular lithotripsy, bifurcation stenting, CTO intervention, and protected PCI with Impella for severely complex coronary disease.

Coronary · Imaging Guided

IVUS & OCT-Guided PCI

Every complex coronary case guided by intravascular imaging — the standard of care that reduces MACE by 30–40% and is now Class I in the 2025 ACC/AHA guidelines.
