Primary

MeasureTime frameDescription
Absence of implant or delivery related serious adverse events at 30 days30 daysAbsence of implant or delivery related serious adverse events at 30 days

Secondary

MeasureTime frameDescription
Procedural Success30 daysAll of the following must be present: I. Deployment of the device II. Absence of major device- or procedure-related SAEs, including: 1. Death 2. Stroke 3. Life-threatening bleeding (Mitral Valve Academic Research Consortium \[MVARC\] definition) 4. Major vascular complications requiring surgery to repair 5. Major cardiac structural complications requiring surgery to repair 6. Stage 2 or 3 acute kidney injury (including new dialysis) 7. Myocardial infarction or coronary ischemia requiring percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) 8. Unexpected cardiogenic shock requiring intensive care unit (ICU) admission and treatments such as ultrafiltration or hemodynamic assist devices, including intra-aortic balloon pumps or left ventricular (LV) or biventricular assist device, or prolonged intubation for \> 48 hours. 9. Any valve-related dysfunction, migration, thrombosis, or other complication requiring surgery or repeat intervention
Device Success30 days, 3, 6, 12 months and annually up to 5 yearsAll of the following must be present: 1. Absence of procedural mortality or stroke; and 2. Proper placement and positioning of the device; and 3. Freedom from unplanned surgical or interventional procedures related to the device or access procedure; and 4. Continued intended safety and performance of the device, including: 5. No evidence of major structural or functional failure 6. No specific, major device-related technical failure issues and complications 7. Reduction of MR to either optimal or acceptable levels\* without significant mitral stenosis (i.e., post-procedure effective orifice area \[EROA\] ≥ 1.5 cm2 with transmitral mean gradient \< 5 mmHg), no greater than mild (1+) paravalvular leak (PVL), and no hemolysis
Patient Success1 yearAll of the following must be present: 1. Deployment of the device 2. Patient returned to the pre-procedural setting; and 3. No rehospitalizations or reinterventions for the underlying condition (e.g., MR, heart failure); and 4. Improvement from baseline in symptoms (e.g., New York Heart Association \[NYHA\] Class improvement by ≥ 1 class); and 5. Improvement from baseline in functional status (e.g., 6-minute walk test/distance \[6MWT/D\] improvement by ≥ 50 m); and 6. Improvement from baseline in quality-of-life (e.g., Kansas City Cardiomyopathy Questionnaire \[KCCQ-12\] improvement by ≥ 10 points)
Change in NYHA Class30 days, 3, 6, 12 months and annually up to 5 yearsNew York Heart Association (NYHA) functional classification of heart failure is based on how much a patient is limited during physical activity. The rating ranges from Class I-IV. Class I = no limitations of physical activity; Class II = slight limitations of physical activity, ordinary physical activity results in fatigue, palpitation, shortness of breath; Class III = marked limitations of physical activity, less than ordinary activity causes fatigue, palpitation, or shortness of breath; Class IV = unable to carry on any physical activity without discomfort, symptoms of heart failure at rest.
Increase in 6MWDfrom baseline to 30 days, 3, 6, 12 months and annually up to 5 years
Technical SuccessProcedureAll of the following must be present: i. Absence of procedural mortality; and ii. Successful access, delivery, and retrieval of the device delivery system; and iii. Successful deployment and correct positioning of the first intended device; and iv. Freedom from emergency surgery or reintervention related to the device or access procedure.
Reduction in MR gradefrom baseline to 30 days, 3, 6, 12 months and annually up to 5 years
Atrial septal defects requiring closure30 days, 3, 6, 12 months and annually up to 5 years
Change in Montreal Cognitive Assessment (MoCa)Discharge and 30 daysThe Montreal Cognitive Assessment is a 30-point test assessing multiple cognitive domains, including short-term memory recall, visuospatial abilities, executive function, attention, concentration, working memory, language, and orientation to time and place. Scores are on a 30-point scale; scores 26 and above indicate normal cognitive function. Lower scores may indicate mild cognitive impairment (scores 19-25), moderate impairment (scores 10-18), or severe impairment (scores less than 10).
Composite of MVARC criteria30 days, 3, 6, 12 months and annually up to 5 yearsNumber of patients who experience composite endpoint events: death due to any cause, repeat hospitalization due to heart failure, disabling stroke, myocardial infarction, life-threatening major bleeding, acute kidney injury, or specific device-related major technical failure issues and complications. b. Repeat hospitalization for heart failure c. Disabling stroke d. Myocardial infarction e. Life-threatening major bleeding f. Acute kidney injury g. Specific device-related major technical failure issues and complications
Quality of life change (KCCQ-12)from baseline to 30 days, 3, 6, 12 months and annually up to 5 yearsThe Kansas City Cardiomyopathy Questionnaire (KCCQ) is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. An overall summary score can be derived from the physical function, symptom (frequency and severity), social function, and quality of life domains. Scores are transformed to a range of 0-100, in which higher scores reflect better health status.
