Objectives:The prolonged natural course of unoperated ventricular septal defects (VSD) in adults leads to complications that change the management of these patients. The need for a special approach to diagnosis and treatment in this group is actual.

The aim of the study is to determine the features of diagnosis and surgical treatment of VSD in adults; to present immediate and long-term results of VSD closure.

Methods:From 1998 to 2015, 162 adult patientsaged 28,4 ± 9.7 years inour center underwent VSD closure without any previous correction. VSD was perimembranous in 88,3%, subarterial in 9,3%, muscular in 1,2%, multiple in 1,2%. Atrial flutter was found in 4%, endocarditis – in 4%. Sinus of Valsalva aneurism rupture was noted in 8,8%, aortic regurgitation – in 9,6%, tricuspid regurgitation – in 5,6%, mitral regurgitation – in 4,2%, subaortic obstruction – in 3,3%, subvalvular pulmonary stenosis – in 9,7%.

Results:In 49,7% VSD was closed with a patch, in other patients VSD was sewed. Closure of sinus of Valsalva aneurism rupture was in 8,8%, aortic valve replacement – in 9,6%, tricuspid valve repair – in 5%, tricuspid valve replacement – in 0,6%, mitral valve repair – in 3,6%, mitral valve replacement – in 0,6%, correction of subaortic stenosis – in 3,3%, correction of subvalvular pulmonary stenosis – in 9,7%. 1 patient underwent CABG. In 72% there was no any associated complications. There was 1 early death due to arrhythmia. 2 patients underwent pacemaker implantation, another patients had uncomplicated hospital period. Survival at 5 years follow up was 100%, freedom from reoperation was 98,8%. 

Conclusions:VSD in adults, even small size, may cause to associated complications, such as arrhythmia, endocarditis or valvular insufficiency, that requires surgical correction. VSD closure in childhood is preferable.
