| Detailed Study Protocol Parameters |
| Study Objectives |
The primary objective of this Portico PAS is to confirm the long-term safety and effectiveness of the Portico valve for
patients undergoing TAVR with the Portico valve and FlexNav delivery system (DS) in a contemporary real-world setting.
The study will be a prospective, single-arm, multi-center, observational real-world surveillance study.
|
| Study Population |
All patients that have undergone attempted TAVR with Portico valve (23, 25, 27, or 29-mm sizes) using FlexNav
Delivery System at a TVT Registry participating site, from the date of PMA approval (September 17, 2021) through
September 24, 2023.
|
| Sample Size |
There is no minimum sample size. The PAS will include all consecutive patients who have a Portico valve with FlexNav
Delivery System implant attempt at institutions participating in the STS/ACC TVT Registry within the first 2 years following
PAS start date.
|
| Key Study Endpoints |
This surveillance will monitor the following: (1) device success (intra-procedure); (2) all-cause mortality, all stroke,
life-threatening/major bleeding, new requirement for dialysis, new pacemaker implant, peri-procedural myocardial
infarction, and repeat procedure for valve-related dysfunction (surgical or interventional therapy) at 30 days
and 12 months; (3) neurological (non-stroke), vascular complications, and quality of life (KCCQ) outcomes at 30 days
and 12 months; and (4) all-cause mortality, all stroke, and repeat procedure for valve-related dysfunction (surgical or
interventional therapy) annually at 2-5 year post implantation.
|
| Follow-up Visits and Length of Follow-up |
Successfully implanted patients will be followed through one (1) year via STS/ACC TVT Registry and through five (5) years
via CMS claims data linkage. Patients with attempted but unsuccessful implants with the Portico valve will be followed
through 30 days post-procedure.
|
| Interim or Final Data Summary |
| Interim Results |
A single Portico valve was implanted in 99.1% of the patients; 2 patients required a second Portico valve.
• The mean Procedure Time was 67.4 -/+ 34.6 minutes.
• Fourteen patients (6.5%) required concomitant procedures.
• Three (1.4%) valve-in-valve implantations.
• A total of 214 patients were discharged after the procedure.
• 30-days endpoints:
o All-cause mortality = 1.0%
o All stroke = 2.9%
o Life threatening or major bleeding = 1.0%
o New requirement for dialysis = 0.0%
o New permanent pacemaker implantation = 17.2%
o Peri-procedural myocardial infarction = 0.0%
o Reintervention – Aortic valve related = 1.0%
o Neurological (TIA / non-stroke) events = 0.5%
o Major vascular complications = 1.4%
o Minor vascular complications = 4.2%

| Actual Number of Patients Enrolled |
216
|
| Actual Number of Sites Enrolled |
17
|
| Patient Follow-up Rate |
Of the 216 patients enrolled, 214 patients have discharge and 30-day follow-up data.
Two (2) patients died post procedure, but prior to discharge.
A total of 16 patients had no follow-up information available for the 30-day follow-up window as of the data cutoff.
