Tilt-table provocation for adults with vasovagal syncope

Multicenter RCT to Assess the Clinical Benefit of Provocation on Tilt-table in SYNCope Patients, TiltSYNC-trial

Not applicable Interventional Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA) · NCT07459478

This trial will test whether adding tilt-table provocation to biofeedback and standard care helps adults with confirmed or highly likely vasovagal syncope avoid future fainting.

What this trial studies

This is a multicenter randomized controlled comparison of two management strategies for adults judged to have certain or highly likely vasovagal syncope after guideline-based evaluation. One group receives biofeedback plus standard care with tilt-table provocation, and the other group receives biofeedback with standard care without tilt-table provocation. Patients are randomized to one of the two approaches and followed for clinical outcomes related to syncope recurrence and symptom burden. The trial addresses a current clinical equipoise because tilt-table testing is widely used but lacks robust randomized evidence for benefit.

Who should consider this trial

Good fit: Adults (age >18) judged to have certain or highly likely vasovagal syncope after standard diagnostic evaluation, who can provide informed consent and have no contraindication to tilt-table testing, are eligible.

Not a fit: Patients under 18, those with other forms of reflex syncope, pre-syncope only, learning disabilities, contraindications to tilt-table testing, or those already diagnosed and referred for specific treatments are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, adding tilt-table provocation could reduce recurrent fainting and help tailor treatment for adults with vasovagal syncope.

How similar studies have performed: Tilt-table testing is commonly used in practice but randomized controlled evidence comparing provocation versus no provocation is lacking, and no definitive RCTs have established clear benefit.
