Aortic Valve Insufficiency
Conditions
Brief summary
The purpose of this study is to assess the efficacy of sacubitril-valsartan compared to the combination of ARB/CCB on left ventricular remodeling in patients with chronic aortic valve regurgitation.
Detailed description
After being informed consent about the study and potential risk, all patients giving written informed consent will undergo a 1 month screening period to determine eligibility for study entry. At week 0, patients who meet the eligibility requirements will be randomized in an open-label manner in a 1:1 ratio to sacubitril-valsartan or amlodipine/losartan.
Interventions
50mg\ 100mg twice daily
amlodipine/losartan 2.5/25mg \ 5/100mg once daily

When it is judged that there are clinically significant abnormalities in physical examination, diagnostic examination, electrocardiogram, etc. at the time of the screening visit
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change of left ventricular end-diastolic volume index from baseline to 12 months follow-up | Baseline and month 12 | Change = \[LVEDV on CMR at 12 months\]-\[LVEDV on CMR at baseline\] |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change of EROA of aortic valve regurgitation from baseline to 12 months follow-up. | Baseline and month 12 | Measurement of regurgitant volume of AR is derived from Doppler imaging on echocardiography. Change = \[regurgitant volume at 12 months\]-\[regurgitant volume at baseline\] |
| Change of LV end-systolic volume from baseline to 12 months follow-up. | Baseline and month 12 | Change = \[LVEDV at 12 months\]-\[LVEDV at baseline\] |
| Change of regurgitant volume of aortic valve regurgitation from baseline to 12 months follow-up. | Baseline and month 12 | Change = \[regurgitant volume at 12 months\]-\[regurgitant volume at baseline\] |
| Change of NT-proBNP level from baseline to 12 months follow-up. | Baseline and month 12 | Change =\[NT-proBNP at 12 months\]-\[NTproBNP at baseline\] |
| Aortic valve replacement or repair operation | During 12 months after enrollment | Any surgical event for correction of AR |
| Holodiastolic flow reversal in the proximal abdominal aorta and descending thoracic aorta from baseline to 12 months follow-up | Baseline and month 12 | presence or absence of holodiastolic flow reversal in the proximal abdominal and descending thoracic aorta on echocardiography |
