[Anatomical correction in transposition of the great arteries and double-outlet right ventricle. Our initial experience].

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.
