Structural heart disease transcatheter procedures have become the fastest-growing cath lab procedure category, with the Cath Lab Market reflecting the expanding procedural volume driven by transcatheter aortic valve implantation, MitraClip mitral valve repair, left atrial appendage occlusion, and a growing pipeline of transcatheter structural interventions that are extending interventional cardiology beyond coronary artery disease into the valve and structural disease traditionally managed by cardiac surgery.

TAVI's remarkable growth trajectory — from fewer than ten thousand procedures globally in 2010 to over two hundred thousand annually — reflects the broadening of patient eligibility from inoperable and high-risk surgical candidates toward intermediate and now low-risk patients, with the PARTNER 3 and Evolut Low-Risk trials demonstrating TAVI non-inferiority to surgical aortic valve replacement in younger, lower-risk patients. The US FDA approval for low-risk patients in 2019 effectively opened the entire aortic stenosis patient population to TAVI consideration.

MitraClip — edge-to-edge mitral valve repair using a percutaneous clip device — has established transcatheter mitral repair as standard therapy for symptomatic secondary mitral regurgitation in heart failure patients ineligible for surgery, with the COAPT trial demonstrating fifty-three percent reduction in heart failure hospitalizations and thirty-eight percent mortality reduction at two years versus medical therapy alone. The CLASP trial results for the Edwards PASCAL device and the TRILUMINATE trial for tricuspid valve repair are extending the structural heart valve repair market.

Do you think transcatheter mitral valve replacement will eventually displace MitraClip edge-to-edge repair as the preferred transcatheter mitral intervention as device iterations improve implant success rates?

FAQ

What is TAVI in the cath lab? Transcatheter aortic valve implantation delivers a replacement aortic valve through catheter access without open heart surgery, currently approved for all surgical risk categories of symptomatic severe aortic stenosis and performed in specialized cath labs or hybrid operating rooms.

What is MitraClip procedure? MitraClip is a transcatheter mitral valve repair procedure using a clip delivered through the femoral vein to approximate the mitral leaflets, reducing regurgitation in patients with symptomatic mitral regurgitation ineligible or high risk for surgical repair.
