Is this trial a fit for you?

Likely a good fit

Adults (18 or older) who can give informed consent and are planning left atrial or left ventricular ablation or combined ablation with left atrial appendage occlusion that requires transseptal puncture are ideal candidates.

Probably not a fit

Patients who are pregnant or nursing, have intracardiac thrombus, recent thromboembolic events, recent myocardial infarction, prior septal patch or closure device, or who are clinically unstable are unlikely to be eligible or to receive benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, acute, first-in-human early feasibility study testing the Agilis RF Transseptal System to cross the atrial septum for left atrial and left ventricular access during electrophysiology and interventional cardiology procedures. The device is used during transseptal puncture in procedures such as left atrial or ventricular ablation and left atrial appendage occlusion device implantation. Subjects are treated in an acute hospital setting and monitored through hospital discharge with no scheduled post-discharge study visits. The study will record immediate procedural success and acute safety outcomes related to crossing the septum.

Why it matters

Potential benefit: If successful, the device could provide a more controlled way to cross the atrial septum, potentially reducing procedure time and acute complications.

How similar studies have gone: Radiofrequency transseptal techniques have been used previously and shown benefits for septal crossing, but this specific Agilis RF system is being tested first-in-human in this acute feasibility study.
