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:
i. 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.

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. |

Clinical Measures of Benefit-Quality of Life (QOL) as Measured by Short Form (SF) 36
Time Frame: 12 months
|
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.
