Abstract
Bilateral pulmonary artery banding (PAB) has emerged to be an attractive option as an initial procedure for the treatment of hypoplastic left heart syndrome (HLHS), and some centers report excellent survival. However, its usage is variable among institutions and its true efficacy is unknown due to reporting biases. We aimed to describe the results of bilateral PAB use, preoperative risk factors, and long-term outcomes compared with primary Norwood procedure, using a national database. Infants who underwent bilateral PAB or Norwood procedure as an initial palliation for HLHS between January 2008 and December 2012 listed in the Japan Congenital Cardiovascular Surgery Database (JCCVSD) were included. The total number of patients diagnosed with HLHS was 334. Bilateral PABs were performed for 256 patients and primary Norwood procedures for 78 patients, as an initial procedure. Actuarial 5-year survival was 59.0%. The primary Norwood procedure group had better 5-year survival [75.5%; 95% confidence interval (CI) 63.2–84.1] than the bilateral PAB group (75.5 vs. 54.0%, log-rank p < 0.001). However, the bilateral PAB group had more significant risk factors. When the risk-adjusted outcomes were evaluated, there was no significant difference between the primary Norwood group and the bilateral PAB group (76.4 vs. 78.1%, log-rank p = 0.87) in higher volume institutions. The primary Norwood group had better 5-year survival than the bilateral PAB group, but preoperative risk was higher in the bilateral PAB group. Because outcomes are comparable when performed at higher HLHS volume institutions, proper patient selection is important in achieving good long-term result.
