Key result
Conductance catheter and sonomicrometry yielded similar changes in right ventricular systolic contractility assessed by the preload recruitable stroke work relationship.
Why the study?
Does the conductance catheter technique provide similar assessments of right ventricular systolic myocardial performance compared to sonomicrometry in a swine model?
Does the conductance catheter technique provide similar assessments of right ventricular systolic myocardial performance compared to sonomicrometry in a swine model?
The conductance catheter technique is a suitable method for assessing changes in right ventricular systolic contractility, performing similarly to sonomicrometry in a swine model.
Confirms conductance catheter equivalence to sonomicrometry for RV contractility in swine; leaves open human translation.

Erb et al. (2002) studied this question. Conductance catheter vs. Sonomicrometry was evaluated on Agreement of preload recruitable stroke work slope. Conductance catheter and sonomicrometry yielded similar changes in right ventricular systolic contractility assessed by the preload recruitable stroke work relationship.
