- Use of Short-term Circulatory Support as a Bridge in Pediatric Heart Transplantation(2015) CANEO, Luiz Fernando; MIANA, Leonardo Augusto; TANAMATI, Carla; PENHA, Juliano Gomes; SHIMODA, Monica Satsuki; AZEKA, Estela; MIURA, Nana; GALAS, Filomena Regina Barbosa Gomes; GUIMARAES, Vanessa Alves; JATENE, Marcelo BiscegliBackground: Heart transplantation is considered the gold standard therapy for the advanced heart failure, but donor shortage, especially in pediatric patients, is the main limitation for this procedure, so most sick patients die while waiting for the procedure. Objective: To evaluate the use of short-term circulatory support as a bridge to transplantation in end-stage cardiomyopathy. Methods: Retrospective clinical study. Between January 2011 and December 2013, 40 patients with cardiomyopathy were admitted in our Pediatric Intensive Care Unit, with a mean age of 4.5 years. Twenty patients evolved during hospitalization with clinical deterioration and were classified as Intermacs 1 and 2. One patient died within 24 hours and 19 could be stabilized and were listed. They were divided into 2 groups: A, clinical support alone and B, implantation of short-term circulatory support as bridge to transplantation additionally to clinical therapy. Results: We used short-term mechanical circulatory support as a bridge to transplantation in 9. In group A (n = 10), eight died waiting and 2 patients (20%) were transplanted, but none was discharged. In group B (n = 9), 6 patients (66.7%) were transplanted and three were discharged. The mean support time was 21,8 days (6 to 984h). The mean transplant waiting list time was 33,8 days. Renal failure and sepsis were the main complication and causeof death in group A while neurologic complications were more prevalent en group B. Conclusion: Mechanical circulatory support increases survival on the pediatric heart transplantation waiting list in patients classified as Intermacs 1 and 2.

- Palliative Senning in the Treatment of Congenital Heart Disease with Severe Pulmonary Hypertension(2015) PENHA, Juliano Gomes; ZORZANELLI, Leina; BARBOSA-LOPES, Antonio Augusto; ATIK, Edimar; MIANA, Leonardo Augusto; TANAMATI, Carla; CANEO, Luiz Fernando; MIURA, Nana; AIELLO, Vera Demarchi; JATENE, Marcelo BiscegliBackground: Transposition of the great arteries (TGA) is the most common cyanotic cardiopathy, with an incidence ranging between 0.2 and 0.4 per 1000 live births. Many patients not treated in the first few months of life may progress with severe pulmonary vascular disease. Treatment of these patients may include palliative surgery to redirect the flow at the atrial level. Objective: Report our institutional experience with the palliative Senning procedure in children diagnosed with TGA and double outlet right ventricle with severe pulmonary vascular disease, and to evaluate the early and late clinical progression of the palliative Senning procedure. Method: Retrospective study based on the evaluation of medical records in the period of 1991 to 2014. Only patients without an indication for definitive surgical treatment of the cardiopathy due to elevated pulmonary pressure were included. Results: After one year of follow-up there was a mean increase in arterial oxygen saturation from 62.1% to 92.5% and a mean decrease in hematocrit from 49.4% to 36.3%. Lung histological analysis was feasible in 16 patients. In 8 patients, pulmonary biopsy grades 3 and 4 were evidenced. Conclusion: The palliative Senning procedure improved arterial oxygen saturation, reduced polycythemia, and provided a better quality of life for patients with TGA with ventricular septal defect, severe pulmonary hypertension, and poor prognosis.
