Why the study?
Does pericardiotomy alter right atrial mechanics and the compensatory response to elevated right ventricular afterload in an open-chest sheep model?
Does pericardiotomy alter right atrial mechanics and the compensatory response to elevated right ventricular afterload in an open-chest sheep model?
Pericardial integrity is essential for the right atrium's ability to compensate for acute increases in right ventricular afterload.
No takes yet. Share an insight, caveat, or question.
Should not change pericardiotomy practice; leaves open pericardial role in human RA compensation to acute RV afterload.
Maniar et al. (2003) studied this question.
