Przezskórna lub chirurgiczna naprawa zastawki mitralnej (PRIMARY)

23 października 2026 zaktualizowane przez: Annetine Gelijns

Przezskórna lub chirurgiczna naprawa wypadania mitralnego i niedomykalności u osób w wieku ≥65 lat (PODSTAWOWE)

This is a prospective, multicenter, open-label, randomized trial comparing mitral valve (MV) transcatheter edge-to-edge repair (TEER) to surgical repair (1:1 ratio) in patients with primary, degenerative mitral regurgitation (MR). The trial will be conducted in the U.S., Canada, Germany, Spain, and the United Kingdom, and is designed as a strategy trial. Thus, all devices legally marketed for TEER of primary degenerative MR in a particular country are eligible to be used in this trial.

Szczegółowy opis

The primary aim of this study is to evaluate the long-term effectiveness and safety of MV TEER compared with surgical repair in patients with primary, degenerative MR. The secondary aim is to analyze the relationship between the adequacy of MR correction at one-year post intervention and longer-term clinical outcomes (death, heart failure hospitalizations/urgent care visits, valve re-interventions, and quality of life). The tertiary aim of this trial is to evaluate a range of patient-centered outcomes (quality of life, functional status, and discharge location) of transcatheter edge-to-edge MV repair compared with MV surgical repair in patients with primary, degenerative mitral regurgitation. This study is closely integrated with the PRIMARY Ancillary Substudy (NCT07103733)

The patient population for this trial consists of adult patients with severe, primary degenerative MR for whom the local heart team has verified that an indication for MV intervention is present and for whom both transcatheter edge-to-edge and surgical repair strategies are anatomically feasible.

Because the use of the commercial edge-to-edge mitral repair device in the U.S. is approved only in patients considered to be at prohibitive risk of MV surgery by a heart team, use of such devices in this trial is considered investigational by the FDA. As such, this trial will be conducted under an Investigational Device Exemption (IDE).

Outcomes will be measured from randomization over a period of 5 years post intervention. The estimated enrollment period is 36 months, and all patients will be followed from randomization for up to 10 years post intervention for particular endpoints. Long-term follow-up will include leveraging administrative datasets linked to clinical trial data.

Aktywny komparator: Surgical mitral valve repair

Patients who are randomized to the surgical arm will undergo mitral surgery.
Procedura: Mitral valve repair

Patients who are randomized to the surgical arm will undergo mitral surgery. Mitral surgery will be conducted using general anesthesia and cardiopulmonary bypass. Mitral surgery may be performed via a sternotomy or a right thoracotomy approach with or without robotic assistance. Standard techniques commonly include a ring or band annuloplasty to correct and prevent annular dilatation; leaflet prolapse and redundancy may be corrected by leaflet resection techniques and / or chordal reconstruction.

Aktywny komparator: Transcatheter edge-to-edge repair

In the transcatheter edge-to-edge repair arm, patients will be treated with a commercially-approved edge-to-edge mitral repair device.
Urządzenie: Transcatheter edge-to-edge repair

Patients will be treated with a commercially-approved edge-to-edge mitral repair device. The steerable guide catheter (guide) is inserted into the femoral vein and advanced across the inter-atrial septum using image guided puncture. Fluoroscopic and echocardiographic guidance will be used to visualize the devices and assess the repair. The guide is positioned over the MV and the clip/clasp delivery system is inserted into the guide and positioned over the MV in accordance with the manufacturer's instructions. The delivery catheter is advanced until the clip/clasp emerges from the tip of the guide into the left atrium. The catheter is manipulated using the control handle until the clip/clasp is correctly oriented with respect to the line of coaptation of the mitral valve. The clip/clasp is opened, and advanced across the mitral valve into the left ventricle then pulled back to grasp the leaflets.

KCCQ has 23 items that map to 7 domains: symptom frequency; symptom burden; symptom stability; physical limitations; social limitations; quality of life; and self-efficacy. The symptom frequency and symptom burden domains are merged into a total symptom score, which can be combined with the physical limitation domain to create a clinical summary score. All scores are scaled 0 to 100, with higher scores indicating better health outcome.

Left Ventricular End Diastolic Dimension (LVEDD)
Ramy czasowe: up to 6 years post intervention

Left ventricular end diastolic dimension (LVEDD) is the diameter across the left ventricle of the heart at the end of diastole, that is, when the heart muscle is maximally relaxed, and usually corresponds to its largest diameter.
up to 6 years post intervention
Left Ventricular End Systolic Dimension (LVESD)

The valve gradient is the difference in pressure on each side of the valve. When a valve is narrowed (a condition called stenosis), the pressure on the front of the valve builds up as blood is forced through the narrow opening. This causes a larger pressure difference between the front and back of the valve. The valve gradient can be used to determine the severity of the valve disorder.
