PV Loop & Coarctation Study
Assessment of the Impact of Transcatheter Stenting of Aortic Coarctation on the Left Ventricular Afterload and Work Using Left Ventricular Pressure Volume Loops
University of Minnesota
20 participants
Jun 4, 2019
OBSERVATIONAL
Conditions
Summary
Coarctation of the aorta accounts for 4-7% of all congenital heart disease. While stent therapy, when feasible, is the standard of care for coarctation, it may not completely improve the work (and afterload) of the heart due to its effects on the elasticity of the aorta. This study will provide the information needed to understand the effects of current management on the cardiac mechanics and work.
Eligibility
Inclusion Criteria2
- Children 6 years of age and older and adults of all races and both sexes referred for elective cardiac catheterization and stent therapy for coarctation
- Those who provide informed consent for study participant.
Exclusion Criteria4
- Children who undergo other interventions in addition to the coarctation
- Children with single ventricle physiology.
- Renal impairment
- Participant unwilling to sign a consent form.

Interventions
The cardiac catheterization procedure will be done according to standard protocol as part of the standard clinical care. This has become the standard of care in any patient in which it feasible and is performed with low risk.
