It attempts to make the right ventricle act like a systemic ventricle, connecting the trunk of the pulmonary artery to the aorta.
Síndrome del corazón izquierdo hipoplástico | American Heart Association
All the analyses were made with SPSS software, version The PICU treatment initiated in the operating room was continued, with the objective to optimize cardiac output and to reduce to the systemic and pulmonary vascular resistance to the maximum.
Norwood procedure is used as the first stage in the palliative treatment of the hypoplastic heart syndrome and can be used, with some technical modifications, in other forms of univentricular heart with aortic stenosis or hypoplasia. Descriptive statistic of the qualitative variables was done, using absolute and relative frequencies. Cardiac arrest with profound hypothermia was used in all and regional cerebral perfusion was used in cirufia.
This article needs additional citations for verification.
The single ventricle is doing nearly twice the expected amount of work because it has to pump blood for the body and lungs. Use of a right ventricle to pulmonary artery conduit did not improve postoperative survival.
The P 50 of the Ce time, aortic clamping and circulatory shutdown was of These differences, which relate the cardiac anatomy to hospital mortality, although spectacular, did not have statistical meaning. July Next article. The one obtained in group 1 was Due to the advancements in medical and surgical treatments, survival of these children in the past years has increased, but they must be intervened 3 times throughout their norwoood, with the risk inherent to this.
Sedation and analgesia were obtained with midazolam and fentanyl, and we only resorted to the neuromuscular paralysis with vecuronium in children whose sternal closure was deferred.

Experience With the Norwood Operation for Hypoplastic Left Heart Syndrome
Six of the patients belonged to group 1 and 2 to group 2. In a similar manner to other authors, 12 we nnorwood also proven that time on ECC is a risk factor for early mortality in the PICU, in the sense that the longer the time on ECC, the most likely the patient will die. A Pediatric Heart Network multicenter study”.
For this motive, and coinciding with the findings of previous studies, they have not been considered as prognostic factors for early mortality. This page was last edited on 4 Augustat The treatment is palliative and it is made in several stages, of which the intervention of Norwood 1 is the first. Cirguia patients died in the perioperative period and three died in the follow up two, four onrwood 10 months after the procedure. Retrieved from ” https: The inferior vena cava IVCwhich carries blood returning from the lower body, continues to connect to the heart.
Because of this, some authors support the systematic use of ventricular assist devices in the operating room and during nodwood patients stay in the PICU, arguing that it improves cardiac output and therefore the survival, of these patients.
Both a long cardiopulmonary bypass time and primary sternal closure were associated with increased mortality.
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. Primary sternum closure was also a risk factor in the sense that the children that underwent such a procedure in the operating room had a higher mortality, both intrasurgically Table 6 as norwoof in the PICU Table 3.
This corrects the hypoxia and leaves the single ventricle responsible only for supplying blood to the body. This fact is related in part with the introduction of a modification in the classical Norwood technique, consisting in the substitution of the fistula for a tube connecting the right ventricle with the pulmonary artery. Between Morwood and June42 children underwent the Norwood procedure.
In most of our patients, nitric oxide was suspended on the third day, and ventilatory support was suspended between the third and ninth day.
The time of aortic clamping only was significant when we compared it with the surgical technique, so that it was superior in children of group 1 Table 7. All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License.
We did not find significant differences either between mortality in PICU and the surgical technique used. The hypoplasic left heart syndrome is a cardiopathy with many anatomical variants that are frequently associated with other malformations or genetical alterations; its proper evaluation and presurgical diagnosis allows us to establish a prognosis, which is independent of the surgical technique and the postsurgical care.
Although the results obtained in the last years have improved, 2,3 it continues to have a high mortality. The second stage, also called Fontan completioninvolves redirecting the blood from the IVC to the lungs. In a review, Dr. In relation to the surgical technique, up until some years ago some authors 16 reconstructed the aortic arch without a homograft; in this way, it was thought, long term growth of the new aorta was benefited without any residual stenosis.
The work done in the previous years has improved short and long-term survival. Seminars in Thoracic and Cardiovascular Surgery.
