Implication

This report demonstrates earlier support with fluoroscopy-free Impella implantation in cardiogenic shock, highlighting its efficiency.

Key Points

To evaluate the feasibility and safety of fluoroscopy-free axillary Impella 5.5 implantation using transesophageal echocardiography for cardiogenic shock.
Developed a fluoroscopy-free technique using transesophageal echocardiography (TEE) guidance.
Utilized a preoperative flowchart for patient selection and access via the right axillary artery.
Implemented TEE-guided pigtail advancement, valve crossing, and device positioning on 19 adults.
Achieved 100% successful implantations without conversion to fluoroscopy-guided procedures or ECMO.
No strokes or major complications observed during the procedure.
All patients experienced optimal positioning and rapid hemodynamic improvement.
