Tetralogy of Fallot repair: optimal z-score use for transannular patch insertion.
OBJECTIVES Transannular patching is used to relieve significant pulmonary annular stenosis during tetralogy of Fallot repair. Although recent literature has focused on the deleterious effects of pulmonary regurgitation, inadequate relief of stenosis may increase postoperative mortality and the re-intervention rate. Patching criteria based on pulmonary annular z-scores are ambiguous because of t...
متن کاملLORETA Z Score Biofeedback
Today we are riding the crest of a wave of converging new neuroscience In the physics of source localization the forward solution is where a source inside a sphere determines the electrical potential on the surface as calculated using Maxwell's 1864 equations. In contrast, the inverse problem is where the sources are unknown and the location of the sources are estimated by measuring the electri...
متن کاملUse of a pulmonary neovalve with a transannular patch for repair of tetralogy of fallot.
INTRODUCTION AND OBJECTIVES To report on our initial experience with the implantation of a pulmonary valve using Nunn's technique in association with a transannular patch for the complete repair of the tetralogy of Fallot. METHODS In total, 21 patients were treated between September 2008 and February 2010. Their ages ranged from 7 months to 15 years (median 12 months) and weights from 6.8 kg ...
متن کاملThe Mystery of the Z-Score.
Reliable methods for measuring the thoracic aorta are critical for determining treatment strategies in aneurysmal disease. Z-scores are a pragmatic alternative to raw diameter sizes commonly used in adult medicine. They are particularly valuable in the pediatric population, who undergo rapid changes in physical development. The advantage of the Z-score is its inclusion of body surface area (BSA...
متن کاملA pediatric echocardiographic Z-score nomogram for a developing country: Indian pediatric echocardiography study – The Z-score
BACKGROUND Almost all presently available pediatric echocardiography Z-score nomograms are based on Western data. They may not be a suitable reference standard for assessing the sizes of cardiac structures of children from developing countries. OBJECTIVE This study's objective was to collect normative data of 21 commonly measured cardiovascular structures using M-mode and two-dimensional echo...
