Use of a Percutaneous Ventricular Assist Device/Left Atrium to Femoral Artery Bypass System for Cardiogenic Shock07:39

Use of a Percutaneous Ventricular Assist Device/Left Atrium to Femoral Artery Bypass System for Cardiogenic Shock

4.1K
The following article describes the stepwise procedure for placement of a device (e.g., Tandemheart) in cardiogenic shock (CS) that is a percutaneous left ventricular assist device (pLVAD) and a left atrial to femoral artery bypass (LAFAB) system that bypasses and supports the left ventricle (LV) in CS.

Summary

Percutaneous techniques can repair left ventricular assist device (LVAD) outflow graft obstruction, a cause of heart failure symptoms. This approach avoids open-chest re-sternotomy, offering a less invasive solution for LVAD dysfunction.

Area of Science:

  • Cardiology
  • Medical Devices
  • Interventional Procedures

Background:

  • Advanced systolic heart failure (HF) often requires left ventricular assist devices (LVADs) for support.
Keywords:
