About this study
Official title: A Study of the Evalve® Cardiovascular Valve Repair (MitraClip®) System Endovascular Valve Edge-to-Edge REpair STudy (EVEREST II) EVEREST II High Risk Registry
Prospective, multi-center, single arm registry. Clinical follow-up at discharge, 30 days, 6, 12, 18 and 24, months, and 3, 4 and 5 years.
Concurrent Control (CC) group identified retrospectively from the patients screened for the HRR who did not enroll; patient survival determined at 12 months. NCT00209274 (EVEREST II RCT) Intended use Percutaneous reduction of clinically significant mitral regurgitation in symptomatic patients who are considered to be high risk for operative mortality (high surgical risk).
Read the detailed description
The EVEREST II HRR is a single-arm prospective, multicenter clinical trial enrolling high surgical risk patients of the EVEREST II study (NCT00209274).
Patients were considered high surgical risk if either their Society of Thoracic Surgery (STS) predicted operative mortality risk was ≥ 12%, or the surgeon investigator determined the patient to be high risk (≥ 12% predicted operative mortality risk) due to the presence of, at a minimum, one of the following pre-specified risk factors:
- Porcelain aorta or mobile ascending aortic atheroma
- Post-radiation mediastinum
- Previous mediastinitis
- Functional MR with ejection fraction (EF) < 40%
- Over 75 years old with EF < 40%
- Prior re-operation with patent grafts
- Two or more prior chest surgeries
- Hepatic cirrhosis
- Three or more of the following STS high risk factors:
- Creatinine > 2.5 mg/dL ii. Prior chest surgery iii. Age over 75 iv. EF < 35%
Upon completion of enrollment in the HRR, a process was initiated to ensure patient consent to participate in a Concurrent Control (CC) group was in place. Patients were identified to determine survival through 12 months with current standard of care treatment.CC patients were derived from a cohort of patients screened for enrollment in the HRR,yet did not enroll. All patients had moderate-to-severe (3+) or severe (4+) MR based on transthoracic echocardiography (TTE). To be considered eligible for inclusion in the CC group, the patient had to be classified as high surgical risk using the same criteria used for the HRR. Upon follow-up with the clinical sites, it was determined that some of the initially identified patients with moderate-to-severe (3+) or severe (4+) MR met the criteria for high surgical risk. Of these patients, some were not included due to; lack of Institutional Review Board (IRB) approval at the site, lack of informed consent and unable to be contacted. The remaining patients make up the CC group.

What is being measured
The primary outcome is the main question the study is designed to answer.
Composite Functional and Structural Measures - Freedom From Death
Defined as all causes of death for the primary safety Major Adverse Event (MAE) Endpoint. Death is further divided into 2 categories:
- Cardiac death is defined as death due to any of the following:
- Acute myocardial infarction.
- Cardiac perforation/pericardial tamponade.
- Arrhythmia or conduction abnormality.
- Stroke within 30 days of the procedure or stroke suspected of being related to the procedure.
- Death due to any complication of the procedure, including bleeding, vascular repair, transfusion reaction, or bypass surgery.
- Any death for which a cardiac cause cannot be excluded.
- Non-cardiac death is defined as a death not due to cardiac causes (as defined above).
Measured: 12 months
Percentage of Participants With Freedom From Death and Mitral Regurgitation (MR) >2+
Kaplan-Meier estimated percentage of patients who are alive and have a mitral regurgitation severity grade of 2+ or less
Measured: 12 months
Number of Participants With Clinical Measures of Benefit-New York Heart Association (NYHA) Class
The major effectiveness endpoint is an assessment of multiple functional and structural measures of benefit including New York Heart Association (NYHA) Class.
Class I: Patients with cardiac disease but without resulting limitations of physical activity.
Class II: Patients with cardiac disease resulting in slight limitation of physical activity. Patients are comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea, or anginal pain.
Class III: Patients with cardiac disease resulting in marked limitation of physical activity. They are comfortable at rest. Less than ordinary physical activity causes fatigue, palpitation dyspnea, or anginal pain.
Class IV: Patients with cardiac disease resulting in inability to carry on any physical activity without discomfort. Symptoms of cardiac insufficiency or of the anginal syndrome may be present even at rest. If any physical activity is undertaken, discomfort is increased.
Measured: 30 days
Number of Participants With New York Heart Association (NYHA) Class
Class I: Patients with cardiac disease but without resulting limitations of physical activity.
Class II: Patients with cardiac disease resulting in slight limitation of physical activity. Patients are comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea, or anginal pain.
Class III: Patients with cardiac disease resulting in marked limitation of physical activity. They are comfortable at rest. Less than ordinary physical activity causes fatigue, palpitation dyspnea, or anginal pain.
Class IV: Patients with cardiac disease resulting in inability to carry on any physical activity without discomfort. Symptoms of cardiac insufficiency or of the anginal syndrome may be present even at rest. If any physical activity is undertaken, discomfort is increased.
Measured: 12 months
Clinical Measures of Benefit-Quality of Life (QOL) as Measured by Short Form (SF) 36
Standardized quality of life surveys allow physicians to evaluate the effectiveness of different treatment methods and the physical and psychological benefits a patient is likely to receive from a particular treatment.In the EVEREST II HRR,the patients were asked to complete the SF-36 QOL survey at baseline, 30 days and 12 months. The physical \& mental function were assessed by the Physical Component Summary (PCS) score \& Mental Component Summary (MCS) score. The PCS \& MCS norms for 65-75 year olds are 44 and 52 respectively; and 31 \& 46 for congestive heart failure (CHF) patients respectively. Each scale from the SF-36 is an algebraic sum of responses for all items in that scale.For ease of analysis each scale is then transformed to a 0-100 scale using a formula that converts the lowest \& highest possible scores to 0 \& 100 respectively.The scoring of the SF-36 indicates that 0% in a domain represents the poorest possible QoL \& 100% indicates full QoL.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Prospective, multi-center, single arm registry. Clinical follow-up at discharge, 30 days, 6, 12, 18 and 24, months, and 3, 4 and 5 years.
Concurrent Control (CC) group identified retrospectively from the patients screened for the HRR who did not enroll; patient survival determined at 12 months. NCT00209274 (EVEREST II RCT) Intended use Percutaneous reduction of clinically significant mitral regurgitation in symptomatic patients who are considered to be high risk for operative mortality (high surgical risk).
Detailed description
The EVEREST II HRR is a single-arm prospective, multicenter clinical trial enrolling high surgical risk patients of the EVEREST II study (NCT00209274).
Patients were considered high surgical risk if either their Society of Thoracic Surgery (STS) predicted operative mortality risk was ≥ 12%, or the surgeon investigator determined the patient to be high risk (≥ 12% predicted operative mortality risk) due to the presence of, at a minimum, one of the following pre-specified risk factors:
- Porcelain aorta or mobile ascending aortic atheroma
- Post-radiation mediastinum
- Previous mediastinitis
- Functional MR with ejection fraction (EF) < 40%
- Over 75 years old with EF < 40%
- Prior re-operation with patent grafts
- Two or more prior chest surgeries
- Hepatic cirrhosis
- Three or more of the following STS high risk factors:
- Creatinine > 2.5 mg/dL ii. Prior chest surgery iii. Age over 75 iv. EF < 35%
Upon completion of enrollment in the HRR, a process was initiated to ensure patient consent to participate in a Concurrent Control (CC) group was in place. Patients were identified to determine survival through 12 months with current standard of care treatment.CC patients were derived from a cohort of patients screened for enrollment in the HRR,yet did not enroll. All patients had moderate-to-severe (3+) or severe (4+) MR based on transthoracic echocardiography (TTE). To be considered eligible for inclusion in the CC group, the patient had to be classified as high surgical risk using the same criteria used for the HRR. Upon follow-up with the clinical sites, it was determined that some of the initially identified patients with moderate-to-severe (3+) or severe (4+) MR met the criteria for high surgical risk. Of these patients, some were not included due to; lack of Institutional Review Board (IRB) approval at the site, lack of informed consent and unable to be contacted. The remaining patients make up the CC group.

Key inclusion criteria (17 listed)
- Candidates for the high risk arm of the study must meet all of the following inclusion criteria:
- Predicted procedural mortality risk calculated using the STS surgical risk calculator of ≥ 12% or in the judgment of the surgeon investigator the patient is considered a high risk surgical candidate due to the presence of one of the following indications:
- Age 18 years or older.
- Symptomatic moderate to severe (3+) or severe (4+) chronic mitral regurgitation (MR) and in the judgment of the investigator intervention to reduce MR is likely to provide symptomatic relief for the patient. MR is determined as defined in Appendix A of the EVEREST II study protocol. American Society of Anesthesiologists (ASA) physical status classification of ASA IV or lower.
- The primary regurgitant jet originates from malcoaptation of the A2 and P2 scallops of the mitral valve.
Key exclusion criteria (28 listed)
- Candidates will be excluded from the study if any of the following conditions are present:
- Evidence of an acute myocardial infarction in the prior 2 weeks of the intended treatment (defined as: Q wave or non-Q wave infarction having creatine kinase (CK) enzymes ≥ two times (2X) the upper laboratory normal limit with the presence of a Creatine Kinase MB Isoenzyme (CKMB) elevated above the institution's upper limit of normal).
- In the judgment of the Investigator, the femoral vein cannot accommodate a 24 F catheter or presence of ipsilateral deep vein thrombosis (DVT).
- Ejection fraction < 20%, and/or end-systolic dimension > 60 mm as defined in Appendix A of the EVEREST II protocol.
- Mitral valve orifice area < 4.0 cm2 as defined in Appendix A of the EVEREST II protocol.
Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.

Number of Participants With Clinical Measures of Benefit-New York Heart Association (NYHA) Class
Time frame: 30 days
The major effectiveness endpoint is an assessment of multiple functional and structural measures of benefit including New York Heart Association (NYHA) Class. Class I: Patients with cardiac disease but without resulting limitations of physical activity. Class II: Patients with cardiac disease resulting in slight limitation of physical activity. Patients are comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea, or anginal pain. Class III: Patients with cardiac disease resulting in marked limitation of physical activity. They are comfortable at rest. Less than ordinary physical activity causes fatigue, palpitation dyspnea, or anginal pain. Class IV: Patients with cardiac disease resulting in inability to carry on any physical activity without discomfort. Symptoms of cardiac insufficiency or of the anginal syndrome may be present even at rest. If any physical activity is undertaken, discomfort is increased.

Standardized quality of life surveys allow physicians to evaluate the effectiveness of different treatment methods and the physical and psychological benefits a patient is likely to receive from a particular treatment.In the EVEREST II HRR,the patients were asked to complete the SF-36 QOL survey at baseline, 30 days and 12 months. The physical \& mental function were assessed by the Physical Component Summary (PCS) score \& Mental Component Summary (MCS) score. The PCS \& MCS norms for 65-75 year olds are 44 and 52 respectively; and 31 \& 46 for congestive heart failure (CHF) patients respectively. Each scale from the SF-36 is an algebraic sum of responses for all items in that scale.For ease of analysis each scale is then transformed to a 0-100 scale using a formula that converts the lowest \& highest possible scores to 0 \& 100 respectively.The scoring of the SF-36 indicates that 0% in a domain represents the poorest possible QoL \& 100% indicates full QoL.
