Our results with the Norwood procedure are similar to other series.
At this point, the oxygen-poor blood from upper and lower body flows through the lungs without being pumped driven only by the pressure that builds up in the veins. The main norwod of this intervention is the hemodynamic instability; in order to try and avoid it, in year the modification of Shunji Sano, 4 consisting of the substitution of the fistula for a non-valvulated tube introduced between the right ventricle and the pulmonary artery.
Views Read Edit View history. Gleen and Fontan procedures were completed in five and one patients, respectively.

This mortality can be considered high if we compare it with that obtained by other authors. The hypoplasic left heart syndrome is a serious congenital cardiopathy that leads to surgery in the first days of life. This procedure improves the growth of the pulmonary arteries with a more uniform distribution.
In the first 30 patients, pulmonary circulation was established using a modified Blalock-Taussig shunt Group 1while a right ventricle to pulmonary artery conduit was used in the remaining 12 Group 2.
Often, cardiac catheterization is performed to check the resistance before proceeding with the surgery. There are four variations of the Fontan procedure: Calls from Spain 88 87 40 9 to 18 hours. We initiated enteral nutrition through a transpyloric tube on the second postsurgical day, preferentially with hydrolyzed maternal milk or proteins.
In relation to the cardiac anatomy, hospital mortality was However, this results in hypoxiaso the fenestration may eventually need to be closed by an interventional cardiologist. Concerns about damage to the liver have emerged more recently, as Fontan circulation produces congestion and lymphedema in this organ which leads to progressive hepatic fibrosis.

The association between each individual variable and mortality was investigated. Fontan procedure for tricuspid atresia. This corrects the hypoxia and leaves the single ventricle responsible only for supplying blood to the body. In relation to the surgical times, only the time of ECC was associated significantly with mortality, so that it was greater in those that died in the operating room Table 6 and in PICU Table 3.
The Journal of Thoracic and Ve Surgery. All of our patients underwent hyperfiltration during their time on ECC, without any complications, and without the necessity of suspending it owing to hemodynamic instability.
For this motive, and coinciding with cifugia findings of previous studies, they have not been considered as prognostic factors for early mortality. Accepted for publication March 29, Screening protocols and treatment standards are emerging in the light of these discoveries. The fraction of the pulmonary dead space is considered normal if between 0.
This fact produces an increase of the dead space, which is translated in a difficulty to exhale carbon dioxide.
Abstract Introduction and objectives. In addition, groups 1 and 2 were compared in relation to mortality, intrasurgical, and postsurgical.
Pericardium Pericardiocentesis D window Pericardiectomy Myocardium Cardiomyoplasty Dor procedure Septal myectomy Ventricular reduction Alcohol septal ablation Conduction system Maze procedure Cox maze and minimaze Catheter ablation Cryoablation Radiofrequency ablation Pacemaker insertion Left atrial appendage occlusion Cardiotomy Heart transplantation.
This experience has made us consider the possibility of using a homograft in a systematic manner, as is being done by other authors with good results, 12 to elevate the position of the aortic arch and reducing the possibility of compressing adjacent structures.
Experience With the Norwood Operation for Hypoplastic Left Heart Syndrome
Although the results obtained in the last years have improved, 2,3 it continues to have a high mortality. Cardiovascular Surgical Procedures ; Heart defects, congenital. Its use has demonstrated in other studies an improvement in hemodynamics, reflected as a reduction in the heart rate and an incremented in the systolic and cirugiia pressure.
These differences, which relate the cardiac anatomy to hospital mortality, although spectacular, did not have statistical meaning. Progress in Pediatric Cardiology. The study was planned as prospective, descriptive, and observational, to be carried out in the period between October and June
