Hybrid management for hypoplastic left heart syndrome : an experience from Brazil.
Initial surgical reconstruction for hypoplastic left heart syndrome (HLHS) is associated with satisfactory outcomes only in a few referral centers. Moreover, there is a persistent high-risk period for sudden death while the patient waits for the next surgical procedure. The development of a less invasive approach, so-called "hybrid," postponing a major surgery outside the neonatal period, might reduce the immediate and late surgical burden on these patients. This is a retrospective study of a contemporary series of patients with HLHS seen in two separate institutions. Patients with HLHS or its variants who underwent a "hybrid" management were included in the study. Data are described as the mean and standard deviation or absolute numbers and percentage, as appropriate. From January 2004 to June 2006, 15 patients (10 male; 5 +/- 3.8 days old and 2.9 +/- 0.5 kg) were included in the study. Ten had both mitral and aortic atresia; the ascending aorta and atrial septal defect measured 2.5 +/- 1.4 and 4.9 +/- 1.2 mm, respectively. There were six hospital survivors after stage I (mortality rate 60%). During the interstage period, all but one patient needed additional procedures. One patient died of bacterial meningitis 4 months after stage I. Four patients were submitted to stage II operation at 6.6 +/- 0.5 months of age and one is waiting for the operation. All four required early reinterventions for pulmonary artery stenosis. Only one was discharged home and was not yet submitted to the third stage. The hybrid approach for HLHS was associated with poor results in this early experience from two independent institutions in a developing country. This might have been related to infrastructure and technical problems, as well as our own learning curve. Institutions working under the same conditions might face similar problems during their initial experience.
