Predictors of Rapid Aortic Root Dilation and Referral for Aortic Surgery in Marfan Syndrome.

Few data exist regarding predictors of rapid aortic root dilation and referral for aortic surgery in Marfan syndrome (MFS). To identify independent predictors of the rate of aortic root (AoR) dilation and referral for aortic surgery, we investigated the data from the Pediatric Heart Network randomized trial of atenolol versus losartan in young patients with MFS. Data were analyzed from the echocardiograms at 0, 12, 24, and 36 months read in the core laboratory of 608 trial subjects, aged 6 months to 25 years, who met original Ghent criteria and had an AoR z-score (AoRz) > 3.

A pilot study of the feasibility of heart screening for sudden cardiac arrest in healthy children.

Background: In children, sudden cardiac arrest (SCA) is associated with structural and electrical cardiac abnormalities. No studies have systematically screened healthy school children in the United States for conditions leading to SCA to identify those at risk.

Methods: From June 2006 to June 2007, we screened 400 healthy 5- to 19-year-olds (11.

Abnormalities of cardiac repolarization in Williams syndrome.

Williams syndrome (WS) affects 1 in 8,000 live births and has a high risk of sudden death. No previous studies have evaluated corrected QT (QTc) prolongation in WS. Retrospective review of all patients with WS evaluated at our institution from January 1, 1980 to December 31, 2007 was performed.

Guidelines for the outpatient management of complex congenital heart disease.

An increasingly complex group of children is now being followed as outpatients after surgery for congenital heart disease. A variety of complications and physiologic perturbations, both expected and unexpected, may present during follow-up, and should be anticipated by the practitioner and discussed with the patient and family. The purpose of this position article is to provide a framework for outpatient follow-up of complex congenital heart disease, based on a review of current literature and the experience of the authors.

The development of the pediatric cardiac quality of life inventory: a quality of life measure for children and adolescents with heart disease.

Objective: Mortality after surgery for congenital heart disease (CHD) has decreased. Quality of life (QOL) assessment in survivors has become increasingly important. The purpose of this project was to create the Pediatric Cardiac Quality of Life Inventory (PCQLI).
