What does this research mean for the field?

A liquid-containing flat balloon accurately measures pericardial constraint across all pericardial liquid volumes, whereas a liquid-filled open-ended catheter significantly underestimates pericardial pressure unless substantial fluid is present.

Does a liquid-containing flat balloon measure pericardial constraint more accurately than a liquid-filled open-ended catheter in a canine model?

Population

Six open-chest anesthetized dogs

Intervention

Pericardial pressure measurement using a liquid-containing flat balloon

Comparator

Pericardial pressure measurement using a liquid-filled open-ended catheter

Outcome

Accuracy of measured pericardial pressure compared to calculated pericardial pressure (difference between left ventricular diastolic pressure before and after opening the pericardium)surrogate

A liquid-containing flat balloon provides a more accurate measurement of pericardial constraint than an open-ended catheter in a canine model.
