New heart valve fix without Open-Heart surgery shows promise
NCT ID NCT07174531
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested a new device called the Renato® system, which allows doctors to place a new heart valve inside a failing one using a thin tube (catheter), avoiding repeat open-heart surgery. It enrolled 150 patients with deteriorated bioprosthetic valves who were at high risk for surgery. The goal was to see if the procedure is safe and effective at restoring valve function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Renato® transcatheter valve-in-valve system (a new artificial heart valve delivered through a tube)
- What this could lead to
- If successful, this could provide a safer, less invasive option for patients with a failed heart valve who are too high-risk for repeat open-heart surgery.
- What could go wrong
- This is a registry study, not a randomized trial, so results may be less definitive. The procedure still carries risks like stroke or need for a pacemaker, and long-term durability of the new valve is unknown.

Inclusion Criteria: 1. Pre-existing bioprosthetic valve with clinically significant structural deterioration (≥ moderate stenosis or regurgitation) in the mitral, aortic, or tricuspid position, mandating re-intervention. 2. Estimated high surgical risk (STS predicted risk of mortality ≥ 8 %) or formal contraindication to redo surgical as confirmed by an independent multidisciplinary heart-team review. Exclusion Criteria: 1. Small true internal diameter of the failing bioprosthesis deemed unsuitable for valve-in-valve therapy by the independent heart-team. 2. Failed mitral bioprosthesis with estimated post-procedural left-ventricular outflow tract obstruction (LVOTO) gradient ≥ 30 mmHg or LVOTO risk classified as "high" by the independent heart-team. 3. Failed tricuspid bioprosthesis with concomitant severe pulmonary hypertension (systolic pulmonary artery pressure \> 60 mmHg). 4. Any additional native or prosthetic valve lesion requiring concomitant surgical intervention, as determined by the independent heart-team. 5. More than trivial paravalvular leak around the failing bioprosthesis. 6. Intracardiac thrombus, mass, or vegetation documented by imaging. 7. Myocardial infarction, coronary-stent implantation, cardiac rhythm-device implantation, stroke, or transient ischemic attack within 30 days before screening. 8. Significant coronary artery disease mandating revascularization. 9. Active infective endocarditis within 6 months of screening. 10. Active infection requiring systemic antibiotic therapy at the time of screening. 11. Life expectancy \< 12 months for any non-cardiac condition.
