Heart failure & cardiomyopathies
Mechanically Reducing Cardiac Preload With the preCARDIA System in Acutely Decompensated Heart Failure
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.
