The leading interventions due to congenital heart defects performed in adults are: (I) reconstructive operations, including: (a) newly diagnosed malformations, (b) previously adjudged to be inoperable defects, (c) so called "tardive" interventions due to pulmonary hypertension or right ventricle insufficiency. There is a growing number of (II) REDO operations, including: (a) correction of residual defects, (b) replacement of damaged or outgrown homografts, (c) recoarctation (aneurysm, dissection) of the aorta after surgical or catheter interventions, (d) Ross procedure, valve replacements due to previously performed aortic valvulotomy/valvuloplasty or corrections of different malformations (e.g. TGA).
Patients and results: 166 of all 4496 operations were performed in adolescents and adults (age: 16-52 years, mean: 28 years) between years 2001-2008. The distribution of these interventions: Ia: 77, Ib: 15, Ic: 4, IIa: 11, IIb: 22, IIc: 9, IId: 28. Mortality rates were the following: 0 intraoperative, 4 early postoperative, 1 pulmonary hypertensive crisis, 1 malignant rhythm disturbances, 2 multi-organ failure.
Conclusions: The main risk factors are pulmonary hypertension and right ventricle failure. Complex surgical solutions do not mean extreme problems for a congenital cardiac surgeon, but earlier diagnosis and the use of ECMO during therapy may improve the results.
