Does a novel catheter technique accurately measure pericardial constraint compared to balloon transducers and DeltaLVEDP in open-chest dogs?
A novel catheter technique accurately measures pericardial liquid pressure, demonstrating that it defines the diastolic constraining effect of the pericardium and suggesting previous measurements were artifactually low.
