Hybrid therapy for hypoplastic left heart syndrome: Myth, alternative, or standard?

OBJECTIVE This retrospective study presents our operative results, mortality, and morbidity with regard to pulmonary artery growth and reinterventions on the pulmonary artery and aortic arch, including key features of our institutional standards for the 3-stage hybrid palliation of patients with hypoplastic left heart syndrome. METHODS Between June 1998 and February 2015, 182 patients with hypoplastic left heart structures underwent the Giessen hybrid stage I procedure. Among these, 126 patients with hypoplastic left heart syndrome who received a univentricular palliation or heart transplantation were included in the main analysis. Median age and body weight of patients at hybrid stage I were 6 days (0-237) and 3.2 kg (1.2-7), respectively. Comprehensive stage II operation was performed at 4.5 months (2.9-39.5), and Fontan completion was established at 33.7 months (21.1-108.2). Operative and interstage mortality, morbidity, growth and reinterventions on the pulmonary arteries, and long-term operative results of the aortic arch reconstruction were assessed. RESULTS Median follow-up time after Giessen hybrid stage I palliation was 4.6 years (0-16.8). Operative mortality at hybrid stage I, comprehensive stage II, and Fontan completion was 2.5%, 4.9%, and 0%, respectively. Cumulative interstage mortality was 14.2%. At 10 years, the probability of survival is 77.8%. Body weight (<2.5 kg) and aortic atresia had no significant impact on survival. McGoon ratio did not differ at comprehensive stage II and Fontan completion (P = .991). Freedom from pulmonary artery intervention was estimated to be 32.2% at 10 years. Aortic arch reinterventions were needed in 16.7% of patients; 2 reoperations on the aortic arch were necessary. CONCLUSIONS In view of the early results and long-term outcome, the hybrid approach has become an alternative to the conventional strategy to treat neonates with hypoplastic left heart syndrome and variants. Further refinements are warranted to decrease patient morbidity.

Application of Continuous Wound-Infusion Catheters in Lung Transplantation: A Retrospective Data Analysis

Background Lung transplantation is the only treatment option for many patients with end‐stage pulmonary disease. Therefore, postthoracotomy pain therapy is of vital interest. Thoracic epidural analgesia (EPI) is the “gold standard” for postthoracotomy pain, but especially in lung transplantation contraindications, and potential infectious complications limit its advantages. Under these circumstances surgically placed postthoracotomy catheter‐assisted continuous paravertebral intercostal nerve block (PVB) could be of advantage. Methods We performed a retrospective cohort study of patients who underwent lung transplantation between 2005 and 2012. Groups were defined according to the type of postoperative pain therapy: PVB, EPI, and SYS (systemic analgesia). Total 44 patients were eligible. Results Postoperative opioid requirement of the PVB and EPI group was comparable and less than that of the SYS group. Patients of the PVB group were weaned earlier from mechanical ventilation after lung transplantation. Conclusion The potency of postoperative pain therapy of EPI and PVB seemed to be comparable and superior to SYS. Considering the risks and benefits, PVB could be a better choice than EPI for postthoracotomy pain therapy, especially in lung transplantation.
