Abstract

Hypoplastic left heart syndrome (HLHS) with intact (IAS) or highly restrictive atrial septum (RAS) has extremely poor outcomes largely related to pulmonary pathology. At birth, immediate left atrial (LA) decompression is required to remain viable, but there is a tradeoff between residual increase in LA pressure and pulmonary overcirculation, either of which exacerbates the pulmonary status. From August 2010 to April 2013, a retrospective chart review was performed on consecutive patients with a prenatal diagnosis of HLHS with IAS/RAS presenting to a single center. The management strategy was immediate LA decompression followed by placement of bilateral pulmonary artery bands (bPAB) and subsequent conventional Norwood procedure. Six patients were born with HLHS with IAS/RAS during this time period with this planned management strategy. Four patients underwent LA decompression and subsequently developed low cardiac output with pulmonary overcirculation. bPAB were used with improvement in cardiac output and pronounced diuresis. These patients all survived the Norwood and subsequent Glenn procedures and remain alive [median follow-up 2.2 years (range 11 months-2.7 years)]. Two patients did not survive with therapy being withdrawn before the Norwood procedure. It is hypothesized that a strategy of total LA decompression followed by bPAB maximizes preoperative systemic perfusion and minimizes ongoing injury to the pulmonary system. This may enhance patient candidacy for the Norwood procedure and long-term survival.
