JACC Heart FailPublished

  • Early feasibility study (single-arm)
  • multicenter
  • prospective

Authors' conclusion

Use of the preCARDIA system in patients with ADHF was feasible and well tolerated, with early exploratory signals of significantly reduced cardiac filling pressures and increased urine output.

Main finding

As reported in the abstract

Device safety and technical feasibility

Freedom from device- or procedure-related major adverse events

98.3% (n = 59/60)

Successful device deployment and removal

all subjects (N = 60)

Observational data: associations, not effects.

Secondary outcomes

Right atrial pressure, baseline vs end of device use (subjects with 24 ± 3 h use)

Decreased by 23% (18 ± 6 vs 11 ± 6 mm Hg)
P < 0.0001
  • n = 52

Pulmonary capillary wedge pressure, baseline vs end of device use (subjects with 24 ± 3 h use)

Decreased by 18% (30 ± 8 vs 24 ± 9 mm Hg)
P < 0.0001
  • n = 52

Net urine output, 24 h before vs 24 h during device use · up to 24 hours

Net urine output increased (−1.5 ± 0.9 vs −3.4 ± 2.4 L)
P < 0.001
