title: [Adult patients after surgery of ostium primum type of atrial septal defects in childhood: echocardiography study].
abstract: The authors examined, using transthoracic and transoesophageal echocardiography, 36 adult patients (15 men) aged 22 +/- 3.1 years (18-29 years) who were operated 12.2 +/- 3.7 years previously on account of a defect of the atrial septum type ostium primum. In these patients no other congenital cardiac defect was present. In addition to closure of the defect in the patients complete suture of the "cleft" of the anterior cusp of the mitral valve was performed, in 7 partial suture of the "cleft" of the anterior cusp of the mitral valve and in 4 commissuroplasty. In one instance later reoperation with replacement of the mitral valve by a mechanical prosthesis was performed. The control group was formed by 16 healthy volunteers (5 men) aged 22.1 +/- 3 years (19-31 years). Patients operated in childhood on account of an atrial defect of the ostium primum type have on echocardiographic examination, as compared with healthy volunteers, larger atria and the left ventricle, a thicker interventricular septum and left ventricular wall and a higher velocity of left ventricular filling during the late diastole. Higher values of parameters of the size and volume of the left ventricle are associated with the presence of mitral regurgitation. More marked changes of systolic or diastolic left ventricular function are not present, there are not even any echocardiographic signs of higher pressure in the atria and pulmonary artery. In none of the patients a residual shunt at the level of the atrial septum is present. Mitral regurgitation is found in two thirds of the patients, only in one case it was however moderately severe (grade 3). From the results it does not ensue which type of surgery of the "cleft" of the mitral valve has the best long-term results. In none of the patients tricuspid regurgitation of a higher grade than grade 1 is present.
