Key result
Cardiopulmonary bypass significantly altered diastolic function, increasing end-diastolic pressure (8 to 16 mm Hg, P<0.05) and chamber stiffness, while systolic indices remained constant.
Why the study?
Does perioperative assessment using the conductance catheter method provide feasible load-independent quantification of left ventricular function in patients undergoing coronary artery bypass grafting?
Observational (n=8)

p-value: p=<0.05
The conductance catheter method is feasible for perioperative pressure-volume analysis, revealing significant changes in diastolic function despite unchanged systolic indices immediately after cardiopulmonary bypass.
No takes yet. Share an insight, caveat, or question.
Post-CPB diastolic impairment may warrant monitoring despite preserved systolic indices; single-case data leaves open conductance catheter role in CABG care.
Tulner et al. (2003) conducted an observational in Coronary artery bypass grafting (n=8). Cardiopulmonary bypass (CPB) vs. Before CPB was evaluated on Left ventricular function parameters (including end-diastolic pressure, relaxation time constant, and chamber stiffness) (p=<0.05). Cardiopulmonary bypass significantly altered diastolic function, increasing end-diastolic pressure (8 to 16 mm Hg, P<0.05) and chamber stiffness, while systolic indices remained constant.
