BACKGROUND: The value of operation of atrial septal defect (ASD) in adults, especially after 40 years, is still discussed. METHODS AND RESULTS: In 1994-95 57 adults with unoperated ASD were examined clinically, echocardiographically and in 75% by catheterization. Type primum was present in 11%, type secundum in 77% and sinus venosus in 11%. Group A comprised 28 patients aged 20 to 40 years (average 29), group B comprised 29 patients aged 40 to 62 years (average 51). The groups (B:A) did not differ in pulmonary to systemic flow (Qp/Qs) (2.4:2.2) or pulmonary arteriolar resistance (PAR) (group B 2 U.m2, group A 1.7 U.m2), the older patients had worse New York Heart Association (NYHA) classification, more frequent tricuspid regurgitation (group B 96%, group A 45%), significantly larger right ventricles and pulmonary arteries, higher mean pulmonary artery pressure (group B 26 mmHg, group A 17 mmHg) and right ventricle end-diastolic pressure (RVEDP group B 10, group A 8.8 mmHg). All defects larger than 10 mm by transesophageal echocardiography (TEE) had Qp/Qs 1.5 or more. Forty patients were operated with zero mortality, in three cases by minithoracothomy. Postoperatively, 50% of group A and 63% of group B felt better, NYHA classification was significantly better in both groups. Tricuspid regurgitation decreased in both groups as well as the size of right ventricle. The size of the left ventricle enlarged after operation in group A. CONCLUSION: This study suggests to operate adults with ASD larger than 10 mm by TEE with signs of right ventricle overload and/or Qp/Qs 1.5 or more, who have normal PAR. Operative mortality was zero in both age groups, the functional repair was better in younger patients (under 40 years).
