Patients over 14 years of age who have undergone a surgical correction of a congenital cardiac malformations during period of August 1959 through December 1993 have been reviewed. During this period, there were 6894 cases of congenital cardiac
lesions
consisting of 4576 acyanotic and 2318 cyanotic cases.
Among them, a total of 1389 adults (20.1%) with various congenital cardiac malformations, 1126 acyanotic group and 263 cyanotic group were operated on. 677 patients were male and 712 patients were female. There were 444 patients under 20 years of
age,
365 patients between 20~24 years, 220 patients between 25~29 years, 138 patients between 30~34 years and 222 patients over 34 years. The most common defects were atrial septal defect which accounted for 500 cases (36.0%) and another common
malformations
were ventricular septal defect (276 cases, 19.9%), pat3ent ductus arteriosus (207 cases, 14.9%), tetralogy of Fallot (185 cases, 13.3%) and pulmonary stenosis (44 cases, 3.2%) in order of incidence.
Overall operative mortality for this series was 2.7% (1.5% of acyanotic group and 7.9% of cyanotic group) compared with 4.6% of operative mortality of total cases of congenital cardiac malformations (2.9% of acyanotic group and 16.7% of cyanotic
group).
This reviewed series reveals the incidence of operable congenital heart defects appearing in any adult life and demonstrates that surgical repair can be accomplished with a satisfactory low mortality rate.
