Patients who have undergone surgical repair of congenital heart diseases are usually not allowed to participate in competitive sports. In the present study we report our long-term experience with 9 male athletes aged 17 to 23 years who participate in competitive sports after undergoing surgical repair of ostium secundum atrial septal defect at a median age of 9 years; six of them play football and three of them volleyball. Competitive sport activities began 1 to 5 years after surgical repair. The mean duration of follow-up is 88 +/- 26 months. Sport fitness was granted on the basis of the following criteria: 1) a normal physical examination; 2) a normal working capacity on exercise test; 3) no arrhythmias on exercise test and Holter monitoring, recorded also during sport activities; 4) a normal M-mode and two-dimensional echocardiography, including the normalization of right ventricular size; the persistence of an abnormal ventricular septal motion did not exclude sport fitness. Recently we also performed Doppler and color Doppler echocardiography and gated equilibrium radionuclide angiography at rest and during exercise. We studied left ventricular diastolic filling through the pulsed wave Doppler evaluation of transmitral flow and measured cardiac output by continuous wave Doppler echocardiography during exercise test in the supine position. We also performed exercise test and M-mode, two-dimensional, Doppler and color Doppler echocardiography in a control group made up of 15 athletes (10 football players and 5 volleyball players). The exercise duration at graded treadmill exercise test (according to the Carù protocol), the maximal heart rate and the maximal systolic blood pressure were, respectively, 12.9 +/- 0.8 min, 192 +/- 10 beats/min and 198 +/- 12 mmHg. Left ventricular end-diastolic dimension, mass and ejection fraction (single-plane area-length method) were 50.3 +/- 2.8 mm, 210 +/- 38 g and 65 +/- 6%. M-mode right ventricular diastolic dimension was 23.4 +/- 1.6 mm; the right ventricular maximal diastolic diameter and area obtained on two-dimensional echocardiography from the apical four chamber view were 44.1 +/- 3.6 mm and 25 +/- 3.8 cm2 respectively. The evaluation of transmitral flow showed the following data: E velocity 77 +/- 12 cm/sec, A velocity 45 +/- 6 cm/sec, E/A ratio 1.7 +/- 0.3, the isovolumic-relaxation period 72 +/- 8 m/sec and the deceleration half-time of the early rapid filling 71 +/- 10 m/sec. A trivial tricuspid regurgitation was detected in 6 subjects; the peak velocity of the regurgitant jet was less than 2.1 m/sec.
