Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is designed to learn more about children who have blockage of the left side of their heart. The goal is to determine how much the heart muscle has thickened before surgery and how it changes in the months after surgery. Investigators are also looking for blood tests that may help them predict which patients will have the most thickening pre-operatively and the best return towards normal after surgery. The findings of this study will help the investigators develop new tests to monitor affected patients and develop new therapies to help minimize heart thickening.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Persistent hypertrophy

Elevated cardiac mass at follow-up time point as measured by Echocardiographic and Serologic evaluations.

Echocardiogram

Intervention Type PROCEDURE

2 and 3-dimensional echocardiographic images will be obtained to estimate LV mass, ejection fraction (Simpson's biplane), fractional shortening (M mode Doppler), and pulse-wave estimated pressure gradient across the outflow obstruction.

Serology

Intervention Type BIOLOGICAL

protein analysis targeting several potential protein biomarkers for cardiac remodeling and hypertrophy as well as targeting known miRNAs.

Normal geometry

Normal cardiac mass at follow-up time point as measured by Echocardiographic and Serologic evaluations.

Echocardiogram

Intervention Type PROCEDURE
