Hypothesis
Can we optimize imaging of coronary veins by understanding their motion during different heart phases in patients with varying ejection fractions?
Conclusion
Patients with low ejection fractions have a longer rest period during systole, while those with moderate ejection fractions have a longer rest period during diastole.
Supporting Evidence
- 95% of patients with low ejection fraction had a longer systolic rest period.
- 100% of CRT candidates had a longer systolic rest period.
- 85% of patients with moderate ejection fraction had a longer diastolic rest period.
Takeaway
Doctors looked at how the veins in the heart move to take better pictures of them. They found that some patients need to take pictures when the heart is resting in different ways.
Methodology
Patients were analyzed using cine MRI techniques to measure coronary vein motion during different heart phases.
Participant Demographics
Patients were divided into three groups based on ejection fraction and ECG results.
