Introduction And Objectives:
Anatomical correction of transposition of great arteries and double outlet right ventricle with subpulmonary ventricular septal defect is a surgical approach that has not been generally adopted in our clinical environment. Our aim with this paper is reporting on our initial experience with this technique.
Methods:
The clinical data and additional investigations are reviewed from 15 infants with transposition of the great arteries and 2 with double outlet right ventricle who underwent anatomical repair, with a postoperative follow-up of one year.
Results:
The survival rate has been 76% (13 out of 17 cases). The 13 survivors are in good hemodynamic condition, with no treatment whatsoever. Thirteen patients are in sinus rhythm with normal repolarization patterns and 5 patients show a right bundle branch block. Neither aortic nor pulmonary gradients have been detected on Doppler examination, and slight valvular insufficiencies are found at aortic level in 4 patients, pulmonary in 2 and mitral in one.
Conclusion:
Anatomical correction is the method of choice for transposition of the great arteries and double outlet right ventricle with pulmonary-related ventricular septal defect.
