The impact of combined mitral stenosis and aortic atresia on outcomes of Norwood procedures for hypoplastic left heart syndrome was examined in a single institution.  The incidence among 74 operated patients was 19%.  Mortality for affected patients was 29% vs 7% for the other patients.   The mechanism of mortality appeared to be myocardial ischemia.  Preoperative angiography did not assist in risk-stratifying patients.
