Material and methods
Between November 1988 and June 1997, all 11 neonates seen with HLHC at The Montreal Children’s Hospital underwent biventricular repair. There were 5 boys and 6 girls. The median age was 7 days (range, 5 to 45 days). The mean weight was 3.59 ± 0.49 kg, and the mean body surface area (BSA) was 0.24 ± 0.04 m2.
Hypoplastic left heart complex consists of multiple hypoplastic structures of the left heart–aorta complex including the mitral valve (MV), the left ventricle, the left ventricular outflow
Postoperative hemodynamics
Most remarkable in the immediate postoperative period was the high LAP. Arterial blood pressure was usually stable with high-dose inotropic support. As early as 6 hours postoperatively, a marked decrease in LAP occurred and by 24 hours postoperatively, LAPs were almost normal (Fig 2).
Structural measurements
The postoperative data were the measurements made at the end of the hospital stay prior to discharge (see Table 1). They did not include measurements on the aortic arch and the ascending aorta, which were
Comment
Hypoplastic left heart syndrome is a term describing a tremendously variable set of structural defects in the left heart–aorta complex. The literature usually reserves this term for extreme underdevelopment of the left ventricle secondary to aortic atresia or stenosis, mitral atresia or stenosis, or both, which makes it incapable of supporting the systemic circulation [1]. Some patients in whom the left heart is unable to support the systemic circulation are probably also found in the
