Official Title: Cardiac Remodeling and Circulating Biomarkers in Pediatric Left Ventricular Pressure Loading Lesions
Brief Summary: 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.
