Patients and Methods
This study was approved by the ethics committee of the Royal Children's Hospital. Between February 1980 and December 2010, 48 consecutive CAVSD–TOF/DORV patients (26 boys, 22 girls) underwent biventricular repair at the Royal Children's Hospital in Melbourne (Fig 2). Median age was 1.8 years (range, 0.2 to 14.8 years). Diagnosis was determined by echocardiogram or cardiac catheterization in all patients. DORV was diagnosed in 22 of 36 patients (45.8%), defined as aortic override greater than
Results
Between January 1980 and December 2010, 26 patients were operated on for CAVSD-TOF. This represented 1.7% of all TOF patients and 5.9% of all CAVSD patients operated on during the same interval. During this interval, 22 patients were operated on for CAVSD-DORV. This represented 13.6% of all DORV patients and 5.2% of all CAVSD patients. Detachment of the superior bridging leaflet was introduced in 1999 and was used in 13 patients, 1 of 21 (4.8%) from 1990 to 1999 and 12 of 17 (70.6%) from 2000
Comment
The CAVSD-TOF/DORV is a rare combination of cardiac anomalies. At the Royal Children's Hospital in Melbourne, 26 patients were operated on for CAVSD-TOF between February 1980 and December 2010. This represented 1.7% of all TOF patients and 5.9% of all CAVSD patients operated on during the same interval. During this time, 22 patients were operated on for CAVSD-DORV. This represents 13.6% of all DORV patients and 5.2% of all CAVSD patients. These figures are similar to those reported in other
