About this study
Official title: The SAVVY Guidewire in Transcatheter Aortic Valve Replacement Procedures: A Feasibility Study
TAVR patients exhibiting post-procedural residual AR had higher mortality and hospitalization rates due to heart failure, with the extent of this association increasing proportionally to the severity of the regurgitation. Optimizing transcatheter valve performance by intra-procedural hemodynamic evaluation of AR and residual transvalvular gradient remains of high clinical importance.
Read the detailed description
Continuous technological development and procedural refinements are important to further reduce TAVR peri-procedural complications, facilitate the minimalist strategy and improve clinical outcomes following TAVR. Residual aortic regurgitation (AR) has been one of the main drawbacks of TAVR. TAVR patients exhibiting post-procedural residual AR had higher mortality and hospitalization rates due to heart failure, with the extent of this association increasing proportionally to the severity of the regurgitation.
Various actions could be undertaken to minimize AR and its consequences, either intraprocedural (balloon post-dilation, implantation of a second valve) or during follow-up (diuretic treatment, closest clinical follow-up or percutaneous leakage closure). Thus, an accurate diagnosis of the presence and severity of residual AR post-TAVR is key to implement the proper measures and optimize clinical outcomes.
The use of cardiac imaging remains the gold standard for evaluating AR post-TAVR, limitations of contrast amount along with the subjectivity of AR evaluation by aortic angiography, and the challenges of echocardiography at the time of the TAVR procedure represent a significant drawback. Thus, alternative tools for evaluating the presence and severity of AR would be very helpful in this setting.
Current data supports the implementation of hemodynamic measurements during TAVR procedures in order to improve the clinical decision-making process following valve implantation. However, these actions entail an inherent risk associated with the exchange of catheter-wires. The use of a support guidewire with pressure measurement capabilities would facilitate the hemodynamic evaluation of transcatheter valve performance in a safer and more rapid manner.
The new SAVVY guidewire, with both dedicated pacing properties and allowing a continuous hemodynamic pressure monitoring during the procedure, is a unique system in the field and may represent an important step forward in the process of optimizing the TAVR procedure while facilitating procedural steps.

Number of effective rapid pacing run
Effective rapid pacing will be defined as an adequate ventricular pacing capture for a minimum of 10 seconds, with no capture loss, and leading to a reduction of aortic pressure of at least 50%, with/or a systolic pressure value <60 mmHg. Efficacy will be assessed by the physician.

Who may be eligible to take part?
The sponsor lists 1 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Presence of Major complications (time frame: Periprocedural). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
