Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: Adult; Older Adult
• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

• Severe aortic valve stenosis diagnosed according to criteria established in current guidelines.
• Intermediate or higher surgical risk, defined as a Society of Thoracic Surgeons (STS) score ≥4%.
• Indication for transcatheter aortic valve implantation (TAVI).
• Willing and able to participate in the study and provide written informed consent.

Exclusion Criteria:

• Any condition considered a contraindication to implantation of a bioprosthetic heart valve (e.g., indication for a mechanical heart valve).
• Known hypersensitivity or contraindication to aspirin, clopidogrel, heparin, nitinol (titanium or nickel), or contrast media that cannot be adequately managed with premedication. This includes heparin-induced thrombocytopenia (HIT) or heparin-induced thrombocytopenia with thrombosis (HITTS).
• Blood dyscrasias, including leukopenia (white blood cell count <1,000/mm³), thrombocytopenia (platelet count <100,000 cells/mm³), history of coagulopathy, or hypercoagulable states.
• Active infection, including endocarditis.
• Cardiogenic shock manifested by low cardiac output, vasopressor dependence, or requirement for mechanical hemodynamic support.
• Stroke or transient ischemic attack (TIA) within 2 months prior to the index procedure.
• History of gastrointestinal bleeding or other bleeding that precludes anticoagulant or antiplatelet therapy.
• Estimated life expectancy of less than 24 months.
• Other medical, social, or psychological conditions that, in the investigator's opinion, may prevent the participant from providing informed consent or adequately complying with the study protocol.
• Pre-existing prosthetic heart valve, either biological or mechanical, in the aortic position.
• Concomitant severe mitral or tricuspid valve disease.
• Hypertrophic obstructive cardiomyopathy.
• Successful percutaneous coronary intervention (PCI) performed within 48 hours prior to TAVI.
• Femoral artery diameter <5.5 mm for SAFESYNC 20-24 mm, <6.0 mm for SAFESYNC 26-28 mm, or <6.5 mm for SAFESYNC 30 mm.
• High risk of aortic annular rupture or significant residual paravalvular leak due to severe calcification of the aortic valve or left ventricular outflow tract.
• High risk of coronary obstruction, defined by computed tomography angiography as coronary ostial height <10 mm with narrow sinuses of Valsalva (SOV), with a mean SOV diameter <3 mm greater than the bioprosthetic valve size.
• Left ventricular dysfunction with left ventricular ejection fraction (LVEF) ≤30%.
• Severe chronic kidney disease, defined as glomerular filtration rate (GFR) <30 mL/min/1.73 m².

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: INOVARE® SAFESYNC Next-Generation TAVI	Device: INOVARE® SAFESYNC Next-Generation Bioprosthetic Heart Valve; Participants will undergo TAVI via transfemoral access using the INOVARE® SAFESYNC Next-Generation Bioprosthetic Heart Valve and the B-Delivery System.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Device Success According to VARC-3 Criteria	Technical success; Absence of mortality; Absence of surgery or intervention related to the device or to major vascular, access-related, or cardiac structural complications; Intended valve performance, defined as mean transvalvular gradient <20 mmHg, peak velocity <3 m/s, Doppler velocity index ≥0.25, and less than moderate aortic regurgitation.	30 days after the procedure

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants Achieving Technical Success According to VARC-3 Criteria	Defined as freedom from mortality; successful vascular access, delivery of the device, and retrieval of the delivery system; correct positioning of a single prosthetic heart valve in the intended anatomical location; and freedom from surgery or intervention related to the device or to a major vascular, access-related, or cardiac structural complication. Results will be reported as the number and percentage of participants achieving technical success.	During the procedure
Incidence and Severity of Paravalvular Leak	Paravalvular leak will be assessed by transthoracic echocardiography and classified according to severity. The number and percentage of participants with paravalvular leak in each severity category will be reported.	30 days, 6 months, 12 months, and annually through 5 years
Mean Transvalvular Aortic Pressure Gradient Assessed	Mean transvalvular aortic pressure gradient will be assessed by transthoracic echocardiography and reported in mmHg.	30 days, 6 months, 12 months, and annually through 5 years
Distribution of Participants by New York Heart Association Functional Class	Functional status will be assessed using the New York Heart Association (NYHA) Functional Classification. The classification ranges from Class I to Class IV, where Class I represents no limitation of physical activity and Class IV represents inability to perform physical activity without symptoms and/or symptoms at rest. Higher NYHA classes indicate worse functional status. Results will be reported as the number and percentage of participants in each NYHA functional class.	30 days, 6 months, 12 months, and annually through 5 years
Incidence of New Permanent Pacemaker Implantation	New permanent pacemaker implantation following the index transcatheter aortic valve implantation procedure will be assessed. Results will be reported as the number and percentage of participants who undergo new permanent pacemaker implantation.	30 days, 6 months, 12 months, and annually through 5 years
Incidence of All-Cause Mortality	All-cause mortality will be assessed throughout follow-up. Results will be reported as the number and percentage of participants who die from any cause.	30 days, 6 months, 12 months, and annually through 5 years
Incidence of Stroke	Stroke events will be assessed based on clinical neurological evaluation and classified according to Valve Academic Research Consortium 3 (VARC-3) definitions. Results will be reported as the number and percentage of participants experiencing stroke.	30 days, 6 months, 12 months, and annually through 5 years
Incidence of Bioprosthetic Valve-Related Reintervention	Bioprosthetic valve-related reintervention will be defined as any surgical or transcatheter intervention performed to treat dysfunction or failure of the implanted study valve. Results will be reported as the number and percentage of participants undergoing valve-related reintervention.	30 days, 6 months, 12 months, and annually through 5 years
Incidence of Bioprosthetic Valve Dysfunction According to VARC-3 Definitions	Bioprosthetic valve dysfunction will be assessed according to Valve Academic Research Consortium 3 (VARC-3) definitions. Bioprosthetic valve dysfunction includes structural valve deterioration, non-structural valve dysfunction, valve thrombosis, and endocarditis. Results will be reported as the number and percentage of participants meeting the criteria for bioprosthetic valve dysfunction and according to the corresponding category.	30 days, 6 months, 12 months, and annually through 5 years
Incidence of Bioprosthetic Valve Failure According to VARC-3 Definitions	Bioprosthetic valve failure will be assessed according to Valve Academic Research Consortium 3 (VARC-3) definitions. Results will be reported as the number and percentage of participants meeting the criteria for bioprosthetic valve failure.	30 days, 6 months, 12 months, 24 months, 36 months, 48 months, and 60 months after the index procedure
