Interventional Cardiology

Innovating and Excelling at Complex Interventional Care

Collaboration across interventional cardiology and cardiac surgery creates optimized care plans for each patient—minimizing surgical trauma and recovery time.


  • World-renowned experts in all structural heart procedures, including transcatheter aortic valve replacement (TAVR) and transcatheter mitral valve repair and replacement
  • Most experience in the world in transcatheter tricuspid valve replacement
  • Pioneers in advanced procedural planning for transcatheter valve therapies
  • Leadership in numerous clinical trials evaluating transcatheter valve replacement for mitral, tricuspid and pulmonary valves, published in journals such as The New England Journal of Medicine, The Lancet and JAMA
  • Faculty editors and contributors to Complex Cases in Structural Heart Intervention, a compilation of richly documented case studies to guide users through complicated situations in interventional cardiology
  • Robust and collaborative teams offering a range of procedures via minimally invasive catheterization


  • Routinely conducting angiography, angioplasty, atherectomy, ablations and valvuloplasty
  • Implantation of temporary and permanent pacemakers, defi brillators and stents

the case

Tom Mazzei (59), male. Patient was referred to CedarsSinai after a heart attack necessitated treatments unavailable in Guam. Mazzei and his wife made the journey to Los Angeles expecting open-heart surgery.

the care

Advanced imaging revealed a blockage in the left anterior descending artery that could be treated via a robotic mammary artery bypass—a procedure available at only a few hospitals across the globe. His surgeon diverted the mammary artery to feed blood to his heart. After a brief inpatient recovery period, Mazzei underwent minimally invasive stent placement via catheterization to relieve the blockage in his right coronary artery. Cross-disciplinary collaboration allowed reduced surgical trauma and a swifter return to physical activity for Mazzei.

the conclusion

Back in Guam for follow-up care with his own cardiologist, Mazzei has renewed his passion for longdistance bike rides and world travel—hobbies he is free to enjoy again with family and friends.

"I was anxious that my life would never be the same after my heart attack. Now, I’m back out there, doing the things I love to do. I was really fortunate to be treated at CedarsSinai.”
