Between 1959 and 1975 at St. Louis University Medical Center, 71 patients underwent surgery with the Blalock-Hanlon technique. Thirty-nine had simple transposition of the great vessels. The mean age at the time of operation was 3.4 weeks. Sixty-four percent were less than 1 month of age. Eighty-five percent survived the operation. In 11 the Blalock-Hanlon procedure was performed after failure of balloon septostomy. Arterial saturation was increased from a mean of 47% to 73%. There were three late deaths prior to Mustard repair (intra-atrial baffle procedure). Sixteen patients underwent Mustard repair at a mean age of 4 years and a mean follow-up of 2½ years. There were three deaths after surgery and three late deaths after the Mustard procedure. The Blalock-Hanlon procedure achieves prolonged palliation, avoiding an emergency Mustard procedure in infancy with its risk of late vena caval obstruction.
