Filter by:The aim is to compare effective growth true hypoplastic pulmonary arteries using Right Ventricle Outflow Tract Reconstruction by femoral allogenic vein valve conduit and systemic-to-pulmonary artery shunts (modified Blalock-Taussig shunt)
Pulmonary artery rehabilitation procedure is done frequently in the catheterization suite for patients with pulmonary artery stenosis or small pulmonary arteries following surgical repair for patients with tetralogy of Fallot with pulmonary atresia and major aortopulmonary collaterals. Considering that the investigators' institution is a major center for treating these cases, the investigators wanted to do a retrospective review of the investigators' data to share the investigators' anesthetic management of these procedures.
The purpose of this study is to determine if the Medtronic Freestyle porcine valve is effective over a long period of time when it is used to replace the valve that normally allows blood to flow from the right lower pumping chamber of the heart to the lungs.
OBJECTIVES: I. Identify latent hypoparathyroidism in normocalcemic adult survivors with repaired conotruncal cardiac defects, by evaluating parathyroid gland secretory function after induced hypocalcemia. II. Determine the relationship of parathyroid hormone secretion to microdeletions in the same region of chromosome 22q11 as found in patients with DiGeorge anomaly.
