Abstract

Objectives. The aim of this study was to perform a retrospective analysis of an institutional experience with a consecutive series of patients with post-stage I palliation for hypoplastic left heart syndrome (HLHS). Background. In a recent review of 212 consecutive patients who underwent stage I operations for HLHS at our institution between 1983 and 1993, we identified risk factors related to stage I mortality. We sought to examine the outcome for these patients at subsequent palliative procedures. Methods. All patients who underwent stage I reconstruction between January 1983 and June 1993 and also underwent subsequent palliation at our institution were included. Seventy patients underwent palliative procedures and two underwent heart transplantation. Patient-specific factors and features of the stage II operation were analyzed for impact on stage II mortality and actuarial survival. Results. The only independent risk factor for stage II mortality was the performance of a nonfenestrated Fontan operation (p < 0.001). There were nine in-hospital deaths (69%) in the 13 patients undergoing the nonfenestrated Fontan procedure at stage II. Fifty patients underwent intermediate superior vena cava to pulmonary artery anastomosis at stage II, with 4 (8%) early deaths. Pulmonary artery augmentation was performed in 19 patients (38%) at stage II, without increased operative risk. Hypoplastic left heart syndrome anatomic subtype did not influence stage II mortality. The modified fenestrated Fontan procedure has been performed as a third stage in 32 patients whose median age was 28.7 months, with one early death at a median follow-up of 24.5 months. Conclusions. A second-stage bidirectional cavopulmonary anastomosis for HLHS reduces second-stage mortality and improves intermediate survival. The modified fenestrated Fontan operation may then be performed as a final palliative stage with low operative risk.
