approach was used in 34 patients. The implanted valve size was 23 mm in 38 patients (66.7%), 26 mm in 
14 patients (24.6%), and 29 mm in 5 patients (8.8%). 

No deaths, no strokes, no major vascular complications, no life threatening bleedings, one (1) renal 
failure, and no new permanent pacemakers were reported at 30 days post implant for the TF population. 
At 1 year post implant, 3 deaths were reported for the TF population.  

In the TA/TAo population, 3 deaths, 1 (major) stroke, 2 major vascular complications, 3 life threatening 
bleedings, and 4 new permanent pacemakers were reported at 30 days. At 1 year post implant, 
4 additional deaths, 1 additional (minor) stroke, 1 additional major vascular complication, and 1 additional 
new permanent pacemaker were reported for the TA/TAo population. 

The PARTNER II Cohort B Aortic Valve-in-Valve Registry (NR3/CANR3) 

A clinical study was performed to establish a reasonable assurance of safety and effectiveness of 
transcatheter aortic valve replacement with the Edwards SAPIEN XT valve in patients with a failing 
surgical bioprosthetic aortic valve (i.e., “TAV-in-SAV”). The study was carried out as a single-arm registry 
nested (i.e., the PARTNER II trial), which was designated as “NR3.” NR3 was originally approved for 
100 patients and later expanded under a Continued Access Protocol (CAP). Data from the original NR3 
cohort and the NR3 CAP (CANR3) cohort were pooled at 30 days and 1 year data was available for the 
NR3 cohort only. 

Patients were treated at 40 investigational sites between June 12, 2012 and December 10, 2013. The 
database for this PMA supplement reflected data collected through February 26, 2015 and included 
199 patients (2 patients withdrew prior to treatment). By the last database extract performed on 
February 26, 2015, all of these patients were included in the 30-day data analysis, and 97 patients were 
included in the 1-year analysis. 

The NR3 study was a single arm, prospective, observational, descriptive study without formal hypothesis 
testing. The patients were limited to those who were deemed by a heart team to have a mortality or major 
morbidity rate of 

≥ 50% for replacement of a failing surgical aortic valve and met the sizing requirements 

for the 23 mm or 26 mm SAPIEN XT valve. The specific sizing requirements were imposed because the 
29 mm SAPIEN XT valve was not available when the study was initiated.  

Contractors were utilized for analysis and interpretation of the clinical data, including an independent Data 
Safety Monitoring Board (DSMB) that was instructed to notify the applicant of any safety or compliance 
issues, a Clinical Event Committee (CEC) that was responsible for adjudicating endpoint-related events 
reported during the trial per definitions established 

a priori

, an Electrocardiography (ECG) Core Lab for 

independent analysis of rhythm and occurrence of myocardial infarction, and an Echocardiography Core 
Lab for independent analysis of all echocardiograms. 

Results of PARTNER II Cohort B Aortic Valve-in-Valve Registry (NR3/CANR3) 

Since identical protocols were used in the pivotal and CAP cohort investigations, data from the two 
cohorts were pooled.  

The “Attempted Implant” population consisted of all screen success patients for whom the index procedure 
was started. The “Valve Implant” population consisted of those patients for whom the valve implant process 
was completed. A total of 199 patients were screened for study participation. Two patients withdrew consent 
prior to treatment; therefore, there were 197 “Attempted Implant” patients. Two “Attempted Implant” patients 
were excluded from the “Valve Implant” population, because in one patient, intra-procedural TEE 
demonstrated a low transvalvular jet velocity (2.6 m/s) and gradient of 24 mmHg which did not meet the 
inclusion criteria, and in the other patient, the procedure was aborted due to inability to place the purse 
string sutures for transapical access. The patient disposition is summarized in Table 14. 

The demographics of the pooled study population are summarized in Table 15. The mean age was 
78.5 years, and 60.4% were male. A high proportion of patients had significant comorbidities, frailty, and 
prior cardiac interventions. The mean STS score was 9.7, and 95.4% of all patients were in NYHA 
classes III or IV. 

Table 16 provides a summary of the failed surgical valves treated, which consisted of 94.4% 
bioprosthesis, 4.6% homografts, and 1.0% other valve types. Aortic stenosis was the predominant cause 
of prosthetic failure (54.2%), followed by mixed lesion (23.4%) and insufficiency/regurgitation (22.4%). 

The primary endpoint of all-cause mortality, all stroke, moderate or severe obstruction, or moderate or 
severe paravalvular leak was 16.9% at 30 days and 38.0% at 1 year, as shown in Table 17.
