CTICasesNuPulse iVAS ambulatory counter-pulsation assist device
Imaging findings
Radiographs show a prior CRT-D device alongside a new investigational mechanical circulatory support device: a subcutaneous lead, a bullet-shaped connector, a radio-opaque anchoring ring at the subclavian artery insertion site, and a gas-filled balloon located in the descending thoracic aorta.
Key takeaways
The NuPulse iVAS (intravascular assist system) is an investigational ambulatory counter-pulsation device. It operates similarly to an intra-aortic balloon pump (IABP) but is inserted via the subclavian/axillary artery, allowing long-term outpatient circulatory support and ambulation.
