About this trial

Mitral regurgitation may be seen in the setting of cardiogenic shock. Transcatheter edge-to-edge repair (TEER) has been shown to improve outcomes in patients with chronic heart failure. Observational studies suggest improvements in clinical outcomes in patients with mitral regurgitation in the setting of cardiogenic shock; however, there remains a lack of randomized clinical data to support the use of TEER in cardiogenic shock.

This study will be a multicenter, open-label, randomized-controlled trial with two study arms: medical therapy and TEER. Patients admitted to the Cardiac Intensive Care Unit (CICU), Cardiac Surgery Intensive Care Unit (CSICU) or Intensive Care Units (ICU) at participating centers will be recruited.

The study aims to answer the question: "Does TEER in patients with SCAI stage C or D cardiogenic with concomitant moderate or greater mitral regurgitation improve outcomes as compared to medical therapy?"

The study hypothesis is that TEER will lead to an overall improvement in the composite outcome as compared to the medical therapy arm.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Participants or substitute decision maker is able and willing to provide written informed consent

Age ≥ 18 years

SCAI stage C or D cardiogenic shock with persistent inotrope/vasopressor/non-durable mechanical support or unable to wean ventilatory support due to pulmonary edema for 24 hours prior to randomization

Greater than or equal to 3+ MR as determined by a study center's transesophageal echocardiogram (TEE)

Disqualifiers

Unwilling or unable to obtain informed consent from the participant or substitute decision maker

Revascularization of coronary artery disease performed in the 48 hours prior to randomization

If the mechanism of MR is deemed to be degenerative, in the opinion of the heart team the participant is eligible for surgical intervention

Prior mitral valve leaflet surgery or implanted mitral valve prosthesis (excluding ring)

Time frame
Through duration of hospitalization, generally up to 12 weeks following admission

Other outcomes

1

All-cause mortality

Death from any cause

Time frame
6 months
2

All-cause hospitalization

Hospitalization is defined as admission to an inpatient unit or ward in the hospital for ≥24 h, including an emergency department stay. Hospitalizations planned for pre-existing conditions are excluded unless there is worsening of the baseline condition.
