Atrial septal defect surgery in adults--populational and epidemiological analysis.

UNLABELLED

Atrial septal defect (ASD) is one of the most common congenital heart diseases found in adolescents and adults. Shunt may lead to serious further complications, such as pulmonary hypertension and right heart chambers overload. The aim of this study was the analysis of the population of adult patients with ASD together with the frequency of the annuloplasty tricuspid ring implantation in ASD II and the necessity of anterior mitral valve cusp suturing due to the cleft accompanying ASD I.

MATERIALS AND METHODS

The study group consisted of 58 males and 122 females aged 17 to 77. Individuals were divided into three age brackets: 17-30 years old--22%; 31-50--38,5% and 51-77--39,5%.

RESULTS

In 92,8% of cases median sternotomy was performed. Other approaches were: right mini- thoracotomy 5%, 2,2% underwent lower hemisternotomy. There were 16 annuloplasties accompanying ASD closure: 13 in ASD II patients, 1 in PFO patient, 2 in ASD I patients. Average size of the pericardiac patch used to ASD type II correction was bigger in patients, who also underwent annuloplasty tricuspid ring implantation (Mann- Whitney U test: -2,25, p=0,024).

CONCLUSION

Repair of ostium secundum and sinus venosus ASD can be performed safely via minithoracotomy endoscopic approach with similar outcomes as sternotomy. Beside the mitral cleft suturing in ASD I patients, annuloplasty tricuspid ring implantation is the most common additional procedure. ASD II patients, who had undergone such annuloplasties needed the bigger pericardial patches.
