Evidence

Sample
N=N=204
Participants
Elderly patients (mean age 83) with heart failure and secondary mitral regurgitation

What This Study Found

Carillon device achieved 98.5% implantation success in 204 HF patients, with improved BNP, functional class, and mitral regurgitation at 3 months.

Key Numbers

N=204; age 83+/-6; 68% female; 72% HFrEF; 98.5% implant success; 94% NYHA improvement at 3 months; 91% MR reduction; 10.4% procedural complications.

How They Did This

Single-center retrospective study of 204 consecutive patients receiving Carillon device from 2021-2024.

Why This Research Matters

Many elderly heart failure patients are too frail for surgery — a minimally invasive 98.5% success rate option fills a critical treatment gap.

The Bigger Picture

Minimally invasive structural heart interventions are expanding options for elderly patients who were previously considered untreatable.

What This Study Doesn't Tell Us

Single-center retrospective study. Only 3-month follow-up. No control group.

Questions This Raises

  • ?Do the benefits persist beyond 3 months?
  • ?How does this compare to surgical mitral repair or MitraClip in similar patients?

Frequently Asked Questions

What is the Carillon device?

A minimally invasive device that repairs a leaking mitral heart valve through a vein, without open-heart surgery — it works by reshaping the valve ring.

Is this procedure safe for elderly patients?

This study showed a 98.5% success rate in patients averaging 83 years old, with low complication rates.
