Successful cardiac resynchronization therapy for treatment of secondary (arrhythmogenic) dilated cardiomyopathy in young children after cardiac surgery
The article presents clinical cases of successful implantation of cardiac resynchronization device (CRT-P). Young children received surgical correction of congenital ventricular septal defect (VSD). Due to the intraoperative development of complete atrioventricular heart block, the electric cardiac pacemaker (ECP) was implanted. The following progression of dilatation of the cardiac cavities, decrease in the left ventricular ejection fraction (LV EF), inefficacy of drug therapy, and the worsening of heart failure required CRT-P implantation.
