Key inclusion & exclusion criteria
|
Inclusion Criteria:
1. Adults =18 years of age
2. Symptomatic FMR of grade moderately severe to severe (3 to 4) with structurally normal
leaflets (preferably with echocardiographic evidence of EROA> 0.20 cm2)
3. NYHA Class II to IV
4. Left Ventricular Ejection Fraction (LVEF) 20%-50%
5. Treatment with optimal guideline-directed medical therapy for heart failure for at
least 30 days. Subjects must be receiving a beta blocker for 3 months and an ACE-I or
ARB for one month unless, in the investigator's opinion, the subject is intolerant to
beta blockers, ACE-I or ARB. Beta blockers and ACE-I (or ARB) doses should be stable
for one month prior to study entry. Stable is defined as no more than a 100% increase
or a 50% decrease in dose.
6. Subjects with a Class I indication for CRT implant according to current guidelines
should have CRT implant prior to entry into the study. Subjects who have existing CRT
implants may be included in the study if the implant has been in place for at least 90
days.
7. Left Ventricular End Diastolic Diameter (LVEDD) of 55 to 80 mm as determined by
transthoracic echocardiography.
8. Subject is willing and available to return for study follow-up
9. Subject or legal representative understands and provides signed informed consent for
participation in study
10. Acceptance of subject for trial enrollment after review of all subject baseline data
by Study Selection Committee
Exclusion Criteria:
1. Life expectancy of less than 12 months due to conditions other than cardiac status
2. Identified need for any cardiovascular surgery
3. Untreated clinically significant coronary artery disease
4. Any procedure, condition or cardiac anatomy that may impact or compromise the
pericardial space (e.g. prior mitral valve surgery, CABG, epicardial pacing leads,
pericarditis, or other procedure involving pericardial access)
5. Percutaneous coronary intervention, acute coronary syndrome (e.g. STEMI or non-STEMI
myocardial infarction, unstable angina) or clinically significant cardiac events (e.g
hypotension, syncope, arrhythmias, embolism, heart failure exacerbation or any
hospitalization) within 30 days of enrollment
6. Thoracic or cardiac surgery contraindication (e.g., acute respiratory distress,
endocarditis, myocarditis, pericarditis)
7. Significant structural abnormality of the mitral valve (e.g. flail leaflets, ruptured
or elongated chordae, prolapsed valve, perforated valve leaflets, significant
calcification in the annulus, or calcification in the leaflets that restricts motion)
8. Severe symptomatic carotid stenosis
9. Severe or sustained pulmonary hypertension, defined by resting pulmonary artery
systolic (PAS) pressure greater than or equal to 70 mm Hg
10. Physical evidence of right-sided congestive heart failure with echocardiographic
evidence of moderate or severe right ventricular dysfunction
11. Hypotension (systolic pressure <90mm Hg)
12. Hypertrophic cardiomyopathy, restrictive cardiomyopathy, or any other structural heart
disease causing heart failure other than dilated cardiomyopathy
13. UNOS status 1 heart transplantation
14. Creatinine > 2.5 mg/dL (221 µmol/L) and/or renal failure requiring dialysis
15. Active systemic infection or bleeding
16. Autoimmune disorders and/or the use of immune suppression therapy
17. Females who are pregnant (as documented by HCG beta pregnancy test in females of
child-bearing age) or lactating
18. Currently enrolled in another investigational drug or device study
Intra-Operative Exclusion Criteria:
1. Subjects with heart size outside of the offered VenTouch System size range
2. Significant structural abnormality of the mitral valve (e.g. flail leaflets, ruptured
or elongated chordae, prolapsed valve, perforated valve leaflets, significant
calcification in the annulus, or calcification in the leaflets that restricts motion)
3. Signs/indications of ischemia
4. Intra-operative coronary angiography demonstrates that there is compression of the
coronary arteries or reduction in coronary blood flow due to the VenTouch implant
