Effects of beta blockers on patients undergoing TAVI for aortic valve stenosis
Official title: Impact of Beta-blocker Continuation Versus Interruption in Patients Undergoing Transcatheter Aortic Valve Implantation
Run by National and Kapodistrian University of Athens · NCT05721170 · Data updated 2026-11-12
This study is testing whether stopping or continuing beta-blocker medication helps adults undergoing heart valve surgery feel better and have fewer complications afterward.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older with severe symptomatic aortic stenosis who are at high risk for surgical aortic valve replacement and currently receiving beta-blockers.
✕Probably not a fit
Patients who do not have severe symptomatic aortic stenosis or are not currently on beta-blocker therapy may not benefit from this study.

What this trial studies
This clinical trial investigates the impact of continuing or withdrawing beta-blocker medication in adults undergoing transcatheter aortic valve implantation (TAVI) for severe aortic valve stenosis. Participants will be randomly assigned to either continue or stop their beta-blocker treatment at least 72 hours before and 7 days after the procedure. The primary focus is on the rates of permanent pacemaker implantation within 7 days post-TAVI, while secondary outcomes include mortality, cardiogenic shock, and arrhythmias over a 12-month period. The study aims to clarify the role of beta-blockers in patients with severe valvulopathy undergoing TAVI.
Why it matters
Potential benefit: If successful, this study could optimize treatment protocols for patients undergoing TAVI, potentially reducing complications and improving outcomes.
How similar studies have gone: While the role of beta-blockers in valvulopathy is not fully understood, similar studies have explored their effects in heart failure and arrhythmias, indicating potential for meaningful insights.
