About this trial

The objective of this study is to demonstrate safety and efficacy of the EmStop Embolic Protection System when used as indicated to capture and remove thrombus/debris during self-expanding transcatheter aortic valve replacement (TAVR) procedures.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Meets FDA-approved indications for elective transfemoral self-expanding transcatheter aortic valve replacement (TAVR) procedure on a native or non-native (valve-in-valve) aortic valve. Note: Due to Neurologist availability and importance of capturing the neurological assessments, procedures must be performed Monday-Thursday.

Left ventricular ejection fraction ≥ 30% as confirmed by echocardiogram

Willing and able to provide written informed consent and written HIPAA authorization prior to initiation of study procedures

Willing and able to comply with the protocol-specified procedures and assessments

Disqualifiers

Requires use of a balloon-expandable transcatheter aortic valve for the index procedure

Documented history of stroke or transient ischemic attack (TIA) within the prior 6 months, or any prior stroke with a permanent major disability or deficit (National Institute of Health Stroke Scale [NIHSS] >1 at baseline)

Left ventricular ejection fraction <30%, cardiogenic shock, or hypotension requiring inotropes or mechanical circulatory support, within 3 months prior to index procedure

Acute myocardial infarction (MI) within 30 days of the planned index procedure

Trial outcomes

Primary outcomes

1

Non-Inferiority

Primary combined safety and efficacy endpoint is the rate of major adverse cardiac and cerebrovascular events (MACCE) at 30-days

Time frame
Non-inferiority of 30-day EmStop device MACCE patient incidence rate compared to the Sentinel device patient incidence rate

Secondary outcomes

1

Non-Inferiority

Hypothesis-driven secondary efficacy endpoint is the composite rate through 30-days post-procedure of NeuroARC defined ischemic embolic stroke, VARC-3 defined AKI, and systemic embolization

Time frame
30 days
2

Debris Capture

Hypothesis-driven secondary efficacy endpoint is the total debris capture, defined as the number of captured particles of at least ≥ 150micron

Time frame
30 days
