Sapien 3

Manufactured by Medtronic
Sourced in Ireland

The SAPIEN 3 is a transcatheter aortic valve replacement (TAVR) system designed for the treatment of severe aortic stenosis. The device is used to replace a patient's diseased aortic valve without open-heart surgery. The SAPIEN 3 system includes a bioprosthetic aortic valve and a delivery catheter system that allows for minimally invasive implantation.

Transcatheter Aortic Valve Implantation Outcomes

Check if the same lab product or an alternative is used in the 5 most similar protocols
Patients with severe symptomatic AS who were treated with TAVI at our institution between December 2014 and September 2016 were deemed eligible for inclusion. All patients were considered to have a moderate-to-high surgical risk according to common risk scores and other clinical parameters (e.g., frailty, presence of porcelain aorta, and sequelae of chest irradiation). Patients were excluded if they were undergoing TAVI because of a degenerated aortic bioprosthesis (valve-in-valve procedure) or an extra-aortic valve treatment (i.e., mitral or tricuspid valve). Patients who died during the periprocedural period were not included. Three different types of prosthesis were investigated in the current study: (1) Edwards Sapien 3® (S3), (2) Medtronic Corevalve® (CV), and (3) Medtronic CoreValve Evolut® R (EVR). The optimal prosthesis size was selected based on anatomical data obtained from computed tomography (CT), which was performed according to the current recommendations for CT imaging before TAVI [6 (link)]. All of the study patients were included in the French TAVI registry and provided their written informed consent.

TAVR was performed at the TAVR centre of the University Medical Center Göttingen, which is certified according to quality requirements of the German Society of Cardiology.17In most of the study participants, an Edwards SAPIEN 3™ (90%) or a Medtronic CoreValve (7%) prosthesis was implanted.

TAVI Protocol for Severe Aortic Stenosis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Between February and October 2016, we recruited subjects with severe AS from patients undergoing clinical TAVI for standard indications. Inclusion criteria demanded use of general anaesthesia, implantation of an Edwards SAPIEN 3 or Medtronic CoreValve Evolut valve, and native AS (no valve-in-valve). Exclusion criteria included moderate or severe aortic insufficiency, mitral regurgitation, or tricuspid insufficiency; hypertrophic cardiomyopathy; unrevascularized, severe coronary disease; myocardial infarction within the preceding 3 weeks; history of significant ventricular arrhythmia; or a prior severe reaction to dobutamine. All subjects gave written informed consent as approved by the medical ethics committee of the hospital.

Outcomes of TAVR in AS Subgroups

Check if the same lab product or an alternative is used in the 5 most similar protocols
This is a retrospective, observational study performed at a single center in the United States. The study was approved by the local institutional review board and exempted from needing an informed consent. All patients who underwent TAVR using a transfemoral approach and using newer generation balloonexpandable or self-expanding bioprostheses (Edwards Sapien 3, Medtronic Evolut R/Pro) at Hartford Hospital between September 2015 and November 2019 were screened for inclusion. Patients with LVEF <50%, low surgical risk, undergoing valve-in-valve procedures, patients with prior MV surgery, and patients with incomplete records were excluded from the analysis. From this cohort, 595 patients were grouped according to their MG determined by resting transthoracic echocardiography. Patients with a MG >40 mm Hg were included in the HG-AS group (n=395). The remaining patients (n=200) were further screened based on their Vmax (transaortic peak velocity) and stroke volume index (SVi to body surface area) where only patients with Vmax <4.0 m/s and SVi ≤35 mL/m 2 where included in the pLFLG-AS group.

Anesthesia Strategies in Transcatheter Aortic Valve Replacement

Check if the same lab product or an alternative is used in the 5 most similar protocols
Among TF-TAVR patients, general anesthesia was used in 242 (42%) and conscious sedation/local anesthesia in 333 (58%). Characteristics of patients undergoing both strategies were generally similar (standardized differences within ±10%), as shown in Supplemental Table E2.
TAVR valves implanted included Sapien (Edwards Lifesciences, Irvine, CA; n = 112, 19%), Sapien XT (n = 354, 63%), Sapien 3 (n = 41, 6.0%), CoreValve (Medtronic, Dublin, Ireland; n = 29, 5.1%), Direct Flow (Direct Flow Medical, Santa Rosa, CA; n = 11, 1.9%), Boston Scientific/Lotus (n = 3, 0.52%), and other (n = 25, 4.3%). SAVR was performed via reoperative full sternotomy in 304 (97%) of the 315 cases.

Prospective TAVI Cohort Study

Check if the same lab product or an alternative is used in the 5 most similar protocols
We conducted a prospective single-center cohort study. Consecutive patients with severe symptomatic aortic stenosis undergoing workup for TAVI with either balloon-expandable (Edwards SAPIEN 3) or self-expandable (Medtronic Evolut R or Evolut Pro) valves between November 2016 and December 2020 were eligible for inclusion at Hôpital Sacré Coeur de Montréal, an intermediate-volume TAVI center in Montreal, Quebec. Excluded patients had either not undergone all imaging modalities or images were not interpretable (i.e., artefacts, no valve section). Patients with a prior bioprosthetic aortic valve were also excluded. The study was approved by the ethics committee and consent was obtained for all participants.

Retrospective Analysis of Transcatheter Aortic Valve Implantation

Check if the same lab product or an alternative is used in the 5 most similar protocols
This retrospective analysis included transfemoral TAVI procedures performed between 2012 and 2019 with balloon-expanding (BE: Edwards Lifesciences Sapien-3), self-expanding (SE: Medtronic Evolut/Evolut-R/Pro, Boston Scientific Acurate-Neo, Abbott Vascular Portico) and mechanically expanding (ME: Boston Scientific Lotus) devices at four high-volume centers in Germany: University Heart Center Hamburg, Kerckhoff Heart and Thorax Center Bad Nauheim, University Heart Center Bonn and University hospital Cologne. In accordance with previous studies [8 (link), 9 (link)], patients with a SAA (defined as annulus area < 400 mm2, measured by multidetector computed tomography (MDCT)) were included. Patients with valve-in-valve procedures, treatment of predominant aortic regurgitation and procedures via non-transfemoral access routes were excluded. Patients were divided into five groups according to the implanted THV (Sapien-3, Evolut, Acurate-Neo, Portico and Lotus).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
