Overview
Brief Summary
The purpose of this study is to evaluate the safety and effectiveness of the 17mm MDT-2215 aortic valve bioprosthesis.
Detailed Description
This is a prospective, interventional, non-randomized, multi-center trial, with each site following a common protocol in Japan. A maximum of 20 subjects will be implanted at a maximum of 10 sites in Japan. The trial will include male and female patients of legal age to provide informed consent in Japan, requiring replacement for a diseased, damaged, or malfunctioning native or prosthetic aortic valve. Patients will be followed and assessed after implant for up to 5 years. This clinical trial information was submitted voluntarily under the applicable law and therefore, certain submission deadlines may not apply. (that is, clinical trial information for this applicable clinical trial was submitted under section 402(j)(4)(A) of the Public Health Service Act and 42 CRF 11.60 and is not subject to the deadlines established by sections 402(j)(2) and (3) of the Public Health Service Act of 42 CRF 11.24 and 11.44.)
Investigators
Eligibility Criteria
Inclusion Criteria
- •Patient has severe aortic stenosis or regurgitation, and there is clinical indication for replacement of their native or prosthetic aortic valve with a bioprosthesis, with or without concomitant procedures, which are limited to any of the following:
- •Left atrial appendage (LAA) ligation
- •Coronary artery bypass graft (CABG)
- •Patent foramen ovale (PFO) closure
- •Ascending aortic aneurysm or dissection repair not requiring circulatory arrest
- •Resection of a sub-aortic membrane not requiring myectomy
- •Patient is geographically stable and willing to return to the implanting site for all follow-up visits
- •Patient is of legal age to provide informed consent
- •Patient has been adequately informed of risks and requirements of the trial and is willing and able to provide informed consent for participation in the clinical trial
- •In the opinion of the investigator, pre-operative imaging indicates the patient may be suitable for a 17mm size valve
Exclusion Criteria
- •Patient has a pre-existing prosthetic valve or annuloplasty device in another position or requires replacement or repair of the mitral, pulmonary or tricuspid valve
- •Patient has had previous implant and then explant of the MDT-2215 aortic valve bioprosthesis
- •Patient presents with active endocarditis, active myocarditis or other systemic infection
- •Patient has an anatomical abnormality which would increase surgical risk of morbidity or mortality, including:
- •Ascending aortic aneurysm or dissection repair requiring circulatory arrest
- •Acute type A aortic dissection
- •Ventricular aneurysm
- •Porcelain aorta
- •Hostile mediastinum
- •Hypertrophic obstructive cardiomyopathy (HOCM)
Outcomes
Primary Outcomes
Number of Participants With Changes in NYHA Classification From Baseline to 1 Year Post-procedure
Time Frame: This outcome will be identified from measurement at baseline and 1 year.
Change in New York Heart Association (NYHA) functional classification from baseline to 1 year post-procedure will be evaluated. Measure Description: Cardiac Disease with Functional Classes (lower value is more desirable than higher value) I - No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation or shortness of breath. II - Slight limitation of physical activity. Comfortable at rest. Ordinary physical activity results in fatigue, palpitation, shortness of breath or chest pain. III - Marked limitation of physical activity. Comfortable at rest. Less than ordinary activity causes fatigue, palpitation, shortness of breath or chest pain. IV - Symptoms of heart failure at rest. Any physical activity causes further discomfort.
Effective Orifice Area Index at Baseline and 1 Year Post-procedure
Time Frame: This outcome will be measured at 1 year.
Effective Orifice Area Index (EOAI) at 1 year post-procedure will be evaluated. Effective Orifice Area Index (EOAI) in cm\^2/m\^2 EOAI = EOA/BSA Where: EOA is the effective orifice area in cm\^2, and BSA is the body surface area in m\^2
Number of Participants With Composite New York Heart Association (NYHA) Classification and Effective Orifice EOAI Endpoint Improvement From Baseline to 1 Year
Time Frame: This outcome will be identified from measurement at baseline and 1 year.
Composite number of participants with NYHA change from baseline to 1 year post-procedure of 1 or greater and effective number of participants with effective EOAI 0.6cm\^2/m\^2 or greater at 1 year post implant will be evaluated. The objective is met if at least 60% of the subjects achieve the specified improvement in NYHA and EOAI. See Objective 1 for NYHA definition See Objective 2 for EOAI definition
