GroupInterventionDescription
Pediatric and adolescent patients receiving CRT with BVP for treating chronic heart failureCRT device implantPediatric and adolescent patients who are receiving cardiac resynchronization therapy with biventricular pacing as a method of treating chronic heart failure. Children of both genders, who are followed in the Division of Pediatric Cardiology at Primary Children's Medical Center, who meet all inclusion and no exclusion criteria are eligible for participation in this clinical study. No intervention is administered as part of this study. Prospective longitudinal case series study to describe and evaluate clinical and hemodynamic effects of CRT and to identify echocardiographic predictors of positive response to CRT in Group described.
Primary Outcome Measures
NameTimeMethod
Collection of quality of life information using the Pediatric Quality of Life Inventory 4.0 (PedsQl v4.0) in children and adolescents with chronic, advanced heart failure (defined by NYHA Functional Classification).Within 30 days of CRT implant to 12 months post implant

Composed of 23 items comprising 4 dimensions. 5-point Likert scale from: 0 (Never) to 4 (Almost always).

Higher scores = Better health related quality of life (HRQOL)

Collection of survival information using the Pediatric Quality of Life Inventory 4.0 (PedsQl v4.0) in children and adolescents with chronic, advanced heart failure (defined by NYHA Functional Classification).Within 30 days of CRT implant to 12 months post implant

Composed of 23 items comprising 4 dimensions. 5-point Likert scale from: 0 (Never) to 4 (Almost always).

Higher scores = Better health related quality of life (HRQOL)

Secondary Outcome Measures
NameTimeMethod
Echocardiographic measurement predictors of positive response to cardiac resynchronization therapy (CRT) in children and adolescent patients according to the American Society of Echocardiography guidelinesWithin 30 days of CRT implant to 12 months post implant

Describe the relationship between echocardiographic measures and subject response to CRT
