Hypothesis
The study aimed to compare two methods of cavity delineation in patients with systemic right ventricle.
Conclusion
The choice of method for systemic RV cavity delineation significantly affected volume measurements.
Supporting Evidence
- Including trabeculations and papillary muscles resulted in higher systemic RV end diastolic and end systolic volumes.
- Ejection fraction was significantly lower when structures were included.
- Analysis time was shorter when using the method that included structures.
Takeaway
This study looked at how to measure the right side of the heart better in patients with certain heart conditions, finding that one way of measuring is faster and more reliable.
Methodology
Twenty-nine patients underwent CMR, comparing two analysis protocols for measuring systemic RV volumes and function.
Limitations
The sample size is relatively small, and the methods used were not suitable for determining which analysis approach was more accurate.
Participant Demographics
29 adult patients (69% male, mean age 34.7 ± 12.4 years) with systemic RV.
