B-24 | Identifying aortic stenosis using seismocardiography

Q: What is the clinical evidence from this study?

Population: Single-ventricle physiology (n=1). Intervention: Modified Micro Vascular Plugs (MVP) fenestration vs. Baseline (no device). Primary outcome: Ratio of total pulmonary to systemic flow (Qp:Qs).

Why the study?

Clinical application of transcatheter palliation using fenestrated Modified Micro Vascular Plugs is hindered by unpredictable Qp:Qs ratios and inconsistent fenestration sizing approaches.

Does seismocardiography-derived indexed amplitude accurately identify patients with aortic stenosis?

Structured PICO

Does seismocardiography-derived indexed amplitude accurately identify patients with aortic stenosis?

P

Population

Patients with aortic stenosis (class ≥2) and a comparative dataset of 78 participants without any history of aortic stenosis. AS patients: mean age 80 ± 6 years, 31% female. Non-AS participants: mean age 70 ± 5 years.

I

Intervention

1-minute resting supine seismocardiography (SCG) measurement to derive indexed waveform amplitude following aortic valve opening

C

Comparator

Comparative dataset of participants without a history of aortic stenosis

O

Outcome

Diagnostic accuracy (Area Under the Curve [AUC]) of indexed SCG amplitude for identifying aortic stenosissurrogate

Limitations

External validation is required for widespread application of SCG amplitude markers
